Character OutlineTsunayoshi "Tsuna" Sawada (沢田 綱吉, Sawada Tsunayoshi) is the main protagonist of Katekyō Hitman Reborn! Although at first a cowardly and useless junior high student, Tsuna is suddenly thrust into fulfilling the role as the tenth generation Boss of the Vongola Famiglia, the most prominent Mafia Famiglia in the world, forcing him to gather his own Guardians to eventually battle for the survival of the world. His character development from a weak individual who easily gives up to a leader dedicated to and willing to fight for the protection of his friends, family, and Famiglia is a critical element of the series. Although he himself does not wish to have anything to do with the Mafia, he nevertheless finds himself thrust into numerous battles, so far involving escaped Mafia exiles, a rival group of elite assassins within the Vongola, ten years in the future, the Millefiore Famiglia, a rival Famiglia in the process of eliminating the Vongola which ended with Tsuna defeating the rival Famiglia's leader, Byakuran, a battle with the Simon Famiglia, former ally of the Vongola, caused by the first generation Mist Guardian Daemon Spade's meddling, and the Representative Battle of the Rainbow, a battle fought to free one Arcobaleno from their curse, Tsuna fighting for Reborn.
As the protagonist of the series, Tsuna appears in all the series' video games, as well as special appearances in both Shōnen Jump compilation games, Jump Super Stars and Jump Ultimate Stars. He also appears in the Hidden Bullet light novels, albeit in a minor role. On July 8, 2008, Pony Canyon released a character CD containing media from both his and Reborn's voice actors.
At the beginning of the series, Tsuna is a junior-high student known in school as "No Good Tsuna" for his poor grades, wimpy attitude, bad luck, and lack of athleticism, a fact which Tsuna freely admits.
Tsuna is generally depicted as comically horrified by the outrageous actions of those around him, generally causing him to become nearly hysterical, especially by Reborn's training methods. His lack of confidence and tremendous lack of luck generally contrast humorously with the positions of leadership and external pressure Reborn puts him in. Despite his title, he seems an earnest individual with great potential; unfortunately, Reborn discovers that often the only way to force Tsuna to fulfill this potential is to put him in a life or death situation.
Although told by others that he is to be the 10th generation Vongola Boss, Tsuna is generally unwilling to take part in anything that has to do with the Mafia. He always denies the fact that he is a going to be Mafia Boss and tries to avoid anyone and anything involved with the Mafia, clinging to any element of an ordinary life he can, even stating that his Guardians and subordinates are just his friends and upperclassmen. Later, though he dislikes the violent history inherent in the Mafia, stating that he would rather destroy the Vongola Famiglia then to accept such a heritage, Tsuna is grateful for the friends he has made since meeting Reborn. He cares a lot for his Famiglia and puts himself in the way of danger and even death in order to protect the members.
Tsuna's personality has developed greatly since the beginning of the manga, from being a cowardly, useless individual who gave up easily, to an individual of great resolve to do whatever he must do to protect the companions he has made. Later, he is depicted as being comfortable with leadership, as the others in his Famiglia look to him for decisions he dispenses without hesitation.
The Tsuna of the future is said to be deceased, having been gunned down; however, not without making arrangements for the future. It is later revealed that the bullet used to gun down Tsuna was just another special bullet (similar to Dying Will Bullet) that replaced the normal bullet in the gun, the deed done by Shoichi Irie. Presumably, the future Tsuna has now settled comfortably into the role of the tenth Vongola Boss.
There have been many similarities between Tsuna and founder of the Vongola Famiglia, Giotto, including physical appearance, fighting techniques, and weapons used. Both of their personalities are likely to be very similar as it has been shown that they have similar goals and ways of standards; for example, neither had problems with appointing Guardians from outside the Famiglia or accepting past enemies into their Famiglia.
One day, the hitman Reborn came to Japan from Italy in order to train Tsuna for the role of being the 10th Vongola Boss. Tsuna was chosen because he was the great-great-great grandson of the First Vongola Boss, who had moved to Japan a long time ago. In the arc, Tsuna always faced trouble caused by either Reborn or his associates with Tsuna saving the day through his Dying Will Mode. It is in this arc that he meets and befriends most of the people that would be his future Famiglia. His Famiglia in this arc was made up of only Gokudera and Yamamoto. He befriended Gokudera when he saved Gokudera from his own attack that had not yet been perfected. Yamamoto became Tsuna's friend when he talked him out of jumping off the roof of Namimori Middle School. The attempt was not shown in the anime because in it, they became friends after a volleyball game. Tsuna also started to bond with Kyoko, becoming friends with her and making a girl named Haru have a crush on him.
Students from Tsuna's school started to get attacked by an unknown group, and Tsuna was assigned to find and to defeat them. When he found that the Gang attacked based on Fuuta's ranking of the strongest people in the school, he realized that Gokudera was their next target. He quickly ran to warn Gokudera, only to find him having already beaten Chikusa. Chikusa, having figured out that Tsuna was the Vongola Boss, he quickly attacked. However Gokudera protected Tsuna, severely hurt himself in the process. Chikusa then continued to attack Tsuna, only for Yamamoto to protect Tsuna too and forced Chikusa to retreat. They then took Gokudera to the school hosptial, and Tsuna blamed himself for not moving in time and forcing Gokudera to protect him. Reborn then told him that the group was Kokuyo Gang, a gang that was exiled from the Mafia and had escaped from a prison. Reborn then read a letter by the Ninth, which told him to destroy the gang or face death.
Tsuna then leaves with Gokudera, Reborn, Yamamoto and Bianchi to the gang's hideout. When Yamamoto is attacked and forced into a one on one match with a gang member named Ken, Tsuna states he should not have brought Yamamoto, as Yamamoto was still playing baseball. That made Reborn kick Tsuna into the fight, forcing Yamamoto to protect Tsuna again and defeat Ken. Afterword they take a break, only to be attacked by M.M. He watches as Bianchi defeats M.M., only for Birds to step forward. Birds reveal his plan to have the Twins attack Haru and Kyoko, unless Tsuna is beaten by his comrades. Tsuna desperately asks Gokudera and Yamamoto to punch him, only for Bianchi to do so, but he states her punch did not hurt at all. Birds then states for Tsuna to stab himself with a secretly poisoned knife, or Kyoko would be hurt. Tsuna, remembering all his friends have done for him, thought that it was nothing for Kyoko. Just as he is about is to stab himself, he sees Dr. Shamal on the screen, and stops as Shamal saves Kyoko and easily defeats one of the twins. Birds says Haru is still in danger, only for him to see Haru protected by Future I-Pin and Future Lambo. Reborns then kicks Tsuna, allowing Tsuna to punch Birds, and then Gokudera defeats Birds. Fuuta then reveals himself and states he now follows Mukuro, causing Tsuna to follow him in the woods. He then mets Mukuro, but does not know who he is. Tsuna then returns to his comrades to find Lancia, who he thinks is Mukuro, eventually beginning to fight him. Tsuna then enters Dying Will Mode and defeats Lancia after a hard fight; however, after the fight he states that Lancia is not evil, suprising Lancia, that he tells Tsuna, he is not truly Mukuro and that Mukuro has messed up his life. Lancia is attacked by Chikusa, only furthering Tsuna's hate towards Mukuro.They then enter the main building where Mukuro is; they then meet Chikusa where Gokudera stays behind to fight Chikusa, allowing Tsuna and everyone else to leave. They meet Fuuta, where he attacked Bianchi, with Reborn stating he is being controlled. Tsuna is able to break Mukuro control of Fuuta, causing Fuuta to faint. Mukuro then attacks, showing Tsuna is hopeless outclassed, until Gokudera with Hibari. Hibari then continues in Tsuna place, seemly defeating Mukuro, only for Mukuro to wake up, and shoot himself. Bianchi then wakes up, and attack both Gokudera and Reborn, with Reborn realizing that Mukuro shoot himself with a special bullet, that allows him to possess anyone, that has been cut by his trident. Mukuro then attacks Tsuna with Gokudera, Bianchi, Chikusa, and Ken's bodies. Tsuna realizes that Mukuro is pushing the bodies to their limits and not caring, and begs him to stop, only for Mukuro to reveal his plan is to take Tsuna's body, to control the Vongola and then destory the Mafia and then start WWIII to destroy the world. Tsuna, feeling desperate, asks Reborn what to do, and Reborn states, do what you feeling tell you to do. Tsuna then states he wants to beat Mukuro, causing Leon to create the Rebuke bullet and the X-gloves. After being shoot by the bullet, he hears everyone rebukes of himself, transforming him to Hyper Dying Will Mode and his X-Gloves to their combat mode, allowing him to defeat Mukuro. He then hear Mukuro past from Ken and Chikusa, causing him to lose his hatred of Mukuro, and feels sorry for all three of them when they are taken by the Vindice, but is happy when the Vongola arrive and provide medical attention to him and his comrades, till he collapses form pain of entering Hyper dying will mode Basil, an agent of the CEDEF, as he was attacked by a swordsman. The swordsman was revealed to be a member of the Varia whose leader, Xanxus, attempts to become the 10th Vongola Boss. Tsuna and his Guardians train with their own tutors for the next ten days in preparation for the Varia's arrival. It is revealed that Tsuna's Father (who was revealed himself to be head of CEDEF) picked Tsuna instead of Xanxus as the Vongola Boss and such, the candidates for the next Vongola Famiglia had to fight against each other for possession of the Vongola Rings.
During the Lightning Ring Battle between Lambo and Lussuria, Tsuna was disqualified (as a result of saving Lambo which rule prohibited) and as such was forced to give up the Sky Ring. After the Cloud Ring Battle, Xanxus sent already defeated Gola Mosca on a rampage and Tsuna was forced to destroy it. However it was revealed to have been powered by the captive Ninth Vongola Boss and his Dying Will Flames. Xanxus accused Tsuna of attempting to assassinate the Ninth and challenged him to a fight. During the "Sky Ring Battle" Xanxus managed to acquire all of the seven Vongola Rings. However his blood was rejected as he was not the Ninth's real son, but only an adopted child of the Ninth, and as a result Tsuna was declared the Tenth Vongola Boss.
Tsuna and company resume their daily routine, but Tsuna is abruptly thrust into another dangerous situation when Reborn unexpectedly disappears instead of being exchanged with his future self when he is shot by the Ten-Year Bazooka. While searching for Reborn, Tsuna himself is shot with the Ten-Year Bazooka and transported 9 years and 10 months into a bleak future, waking up in a coffin, having supposedly died. He is then met by Future Gokudera, who tells him to find and assassinate a boy named Shoichi Irie to prevent this strange Future from happening, although what specifically this would do was not yet revealed. Before he can explain further, he is replaced by his Past self. Much to their surprise, they do not returned to the past after five minutes. Tsuna and Gokudera soon come in contact with the future Vongola Famiglia, who are being slowly annihilated by a rival Famiglia, the Millefiore Famiglia, and driven into hiding. It seems that the Future Tsuna ordered the destruction of the Vongola Rings, putting the Vongola at a disadvantage; most of the Famiglia's higher-ups and allies have already been eliminated.
Motivated by a desire to prevent this Future from coming about, as well as to return to the Past, Tsuna is advised by Reborn to gather the Guardians, starting with the strongest Guardian, Hibari. In the process, the Vongola Battle numerous times with the Millefiore; while, fortunately, Tsuna learns how to use his Vongola Ring. His antics also alert the Millefiore to the presence of not only the existance of Tsuna being alive, but the Vongola Ring's location.
Events soon conspire that transfer most of Tsuna's friends and Famiglia to the future, making it imperative to return to the past; in order to accomplish this, Gokudera reveals it is necessary to defeat Byakuran, the head of the Millefiore Famiglia, with the Vongola Rings. Thus, Tsuna and the Guardians from the Past undergo training to learn this Generation's unique style of fighting that is, using Boxes and Rings, in preparation for an attack on the Millefiore Base to be conducted in tandem with Vongola operations against the Millefiore worldwide.
Tsuna's training with Hibari drives him near death, forcing him to undergo the Vongola Trial of Succession. Tsuna's declaration of his resolve before the former Vongola Bosses yields the ability to combine the power of the Vongola Ring with his X-Gloves, producing the X-Gloves Version V.R. (Vongola Ring); while more powerful, the Gloves are unbalanced and difficult to handle. However, Tsuna is able to use the Gloves' increased to power to develop a new technique, the X-Burner, before the scheduled raid on the Millefiore Base. During this time, Tsuna also receives a premonition about a circular white machine with Shoichi Irie standing in front of that seems to have something to do with traveling back to the Past. Tsuna also begins to become more accustomed to the idea of Leadership. However, the Millefiore discover the location of the Vongola Base and attempt to ambush the Vongola in the middle of the night, forcing the Vongola to attack earlier than expected. Tsuna and company infiltrate the Melone Base, which they discover is conveniently led by Shoichi Irie. Although the group dispatched several Millefiore thugs, Shoichi Irie soon plays his hand and manipulates the placement of the Base's rooms to separate the group.
Additionally, Tsuna is captured by a Millefiore technician, Spanner, after remaining behind as a decoy and defeating a force of Strau Mosca robots. Surprisingly, Spanner does not kill him, but instead offers to help Tsuna complete the X-Burner technique, on the grounds that he wishes to see it completed. Tsuna cooperates with Spanner after Reborn (who appears via hologram) urges him to; Spanner constructs Tsuna to use Contacts Lens to improve his X-Burner. Tsuna proceeds to use the X-Gloves to obliterate numerous Millefiore agents and obstacles, developing new Techniques, as he and Spanner, who are labeled a traitor, make their way to the control room to confront Shoichi Irie.
After receiving word of the Varia's victory in Italy, learning of the Real Six Funeral Wreaths and of the plot hatched between Future Tsuna, Future Hibari, and Future Irie. Tsuna asks Spanner and Irie to join the Vongola Famiglia and receives the Sky Vongola Box from the Future Irie. He begins training again in preparation for the Battle of Choice initiated by Byakuran. However, his Box Weapon attacks him when he first tries to open it.
To make matters worse, mid-training, Haru and Kyoko decide to stop doing household chores, as both become aware they are being left out of the loop; Tsuna ultimately reveals the entire situation to both of them, receiving advice from Kyoko that allows him to open his Vongola Box correctly.
An anime filler Arc in which Tsuna and his Guardians are sent momentarily back to the past to obtain the seven Arcobaleno Seals, which are requirements for opening the Vongola Boxes. In the manga, there is no such requirement. Instead of Tsuna and everyone going back to the past for the Trials, Byakuran reveals he'd known Irie was going to betray him all along and informs them of the real Millefiore Guardians/Funeral Wreaths.Tsuna has just cleared all the Trials. He had cleared Colonnello's Trial that tests Combat Ability and Skull's Trial of Charisma in the same day. He has also completed Mammon's (Viper's) trial of adaptability. In that Trial, Mammon had pretended to take Kyoko as a hostage while she was actually shopping/drinking tea with "Himeko" (Belphegor). The Trial involved solving riddles and battling box weapon prototypes. Only Tsuna, Ryohei and Yamamoto participated in this trial. In the end, Tsuna defeated Mammon using the X-Burner. Fon, the holder of the Red Pacifier, was next with his Trial of Leadership. The test was to catch him in one hour with all the people Tsuna had in the school: himself, Haru and Lambo, and also secretly, I-Pin, who showed herself in the end to help Tsuna catch her master. With Hibari also there (he doesn't help, but beats Tsuna up, which causes him to fall unconscious and catch Fon), they succeeded and Tsuna got the Seal.
With only 3 days remaining until they had to return to the Future, Aria, the holder of the Orange Pacifier (which doesn't have any qualities the Arcobaleno have, except the Pacifier, rather the appearance of a woman), gave Tsuna the Trial of Tolerance, the acceptance of others even though he doesn't know them thoroughly. Tsuna passed the Trial and received the Sky Arcobaleno Seal. At the end of the day, Reborn states that he will be the one to give Tsuna and the Guardians the next Trial. Reborn gives the Trial on Namimori Island with all of the Guardians involved. Starting the Trial, Reborn kicks Tsuna into a boulder, knocking him unconscious. After that, Reborn defeats the Vongola Guardians one by one. Tsuna awakens and has a chance to defeat Reborn with the X-Burner but stops mid attack, thinking that he can't hurt Reborn because of their friendship. Reborn then defeats Tsuna and tells him that he has failed the trial.
All the Guardians except Hibari and Lambo later awaken to find themselves in a tower on the beach. After contemplating what to do next, Tsuna, Ryohei, Yamamoto, and Gokudera decide to ask Reborn for another chance. Before Reborn can answer, Verde shows up and, announcing that he wants the Vongola Rings to try to perfect his Box Weapons, attacks the weakened Vongola Guardians, including Hibari and Lambo, both of whom are in Namimori Town. By not giving his own Trial saying "he could not care less about the pact", Verde has broken the Arcobaleno Pact and the other Arcobaleno join in to help. This was Verde's plan all along and he captures all the Arcobaleno and demands that Tsuna gives him the Rings. Tsuna refuses and they try to save the Arcobaleno. Verde blows up the Arcobaleno, but it is revealed that they were never captured but were instead hidden in an illusion by Viper. Tsuna ends the battle with his X-Burner and destroys Verde, but he turns out to be a robot.
Tsuna senses that Verde is near and is in Namimori. Reborn thinks that maybe Tsuna's prediction may be correct. Gokudera thinks that maybe Verde is in Bumpy Rock, the small island where they had once held a swimming competition around. They have found Verde's secret underground laboratory, so Tsuna passed Verde's Trial of Intuition. With 6 Seals, they asked Reborn if they could have another fight but Tsuna didn't know that he already passed his Trial. Tsuna had actually passed it when he battled Verde and the Box Weapons even with their injuries, and thus is granted the seal. With all 7 seals, they went home. The next morning, Tsuna, Gokudera, Yamamoto, Ryohei, Chrome, Lambo, Reborn, Kyoko, Haru, and I-Pin go to the Namimori Shrine, and they return to the Future using the 10-Year-Bazooka they found there, except for Tsuna and Reborn, who were waiting for Hibari. After a long time of waiting, Hibari did not show up, and Reborn forces Tsuna into the Bazooka. In the Future, they realize that Hibari actually went there early.Millefiore Mist Funeral Wreath, Torikabuto; however, Tsuna was ultimately trapped within an Illusion. During the Battle, he demonstrates not only his increased strength and the power of the Vongola Sky Box but again with his role as the Tenth, giving orders when the battle turns grim. However, he was too late to prevent Shoichi from being attacked, and the Vongola lost the Choice Battle. Shoichi woke up to find out that they had lost the Choice Battle. Tsuna didn't understand why it is so important to win even if it is for all of humanity. Shoichi then goes on to explain his past experiences and Byakuran's power.
Shoichi continues to explain that the reason Byakuran's so powerful is that he could take the best of the parallel worlds he exists in and use that knowledge to conquer each of them. Another big surprise is that Shoichi used a special bullet to put Future Tsuna into a death like state and was actually alive and that he knew the only help to defeat the Millefiore was that the Past Vongola Decimo and his Guardians defeat them. Tsuna finally understands why they are the only hope but it is too late. Byakuran demands the Vongola Rings as they had lost, but Shoichi asks for a rematch as the last time they played Choice, Byakuran had lost, failed to pay and therefore had offered Shoichi any condition that Shoichi wanted next time they played. Byakuran denies this had ever happened and rejects the rematch as Boss of the Millefiore Famiglia. However the Sky Arcobaleno Yuni arrives, having been cured form an inflicted Drug which 'erases' emotions, and reveals that this bet, had taken place. When Byakuran continues to deny this, Yuni leaves the Millefiore, and asks Tsuna to protect her.
After he and the others managed to escape from Byakuran, he along with everyone else from the past, gathered at Irie's device and returned to the past. He meets with Vongola Primo at Namimori Shrine, where they were told that they had yet to inherit the true power of the Vongola and to gain it, they had to be accepted as a true boss and true Guardians by the first-generation Vongola Famiglia.
He cheered for Yamamoto during his trial, and played a role in convincing the First Generation guardians during Lambo and Gokudera's trials, while in Alaude and Knuckle's trial, he, along with everyone else, tried to convince Hibari to take the test, but in vain. He was later involved in trying to evacuate the students when Skull went on a rampage.
In Daemon Spade's trial on the way to Kokuyo Land, he and the others met Ken and Chikusa who immediately blamed them for Chrome's strange behavior. When they arrived at Kokuyo Land, they found Chrome in a depressed state. The girls requested the guys to leave Chrome to them. When evening fell, Tsuna and the guardians (excluding Hibari) decided to go check on the girls, as they haven't returned yet. When they get there, Daemon Spade traps the girls inside the building and confronts the guardians, saying that he didn't approve of any one of them who will carry on the Vongola Famiglia.
Daemon Spade revealed that he controlled Chrome to draw out Kyoko and the others so that he could force Tsuna and the others to accept his demands. Tsuna, Gokudera, Yamamoto, Ryohei and Lambo accept Daemon's challenge, and soon begin to battle clones of themselves. During the battle, Daemon comments that Tsuna is weak and not worth protecting, Gokudera, however, protects Tsuna and asks him to run while he holds Daemon back, but Tsuna chooses to join the fight by going into Hyper Dying Will Mode.
As the battle goes on, Daemon Spade reveals to Tsuna and Gokudera that he is the one who forced Giotto to step out of the Vongola and flee to Japan, not the Vongola Secondo. Tsuna and Gokudera were shocked to hear that. Tsuna then was hit by Daemon Spade (who had transformed into an illusion of Tsuna) many times until Tsuna used the X-Burner; however, Daemon Spade mimicked his X-Burner. When Tsuna was about to fire it, Gokudera tripped in between them so Tsuna stopped his attack. Daemon then fired the X-Burner. However, he did not know that Tsuna could use the Zero Point Breakthrough: First Edition. Daemon Spade asked him why he did not want to succeed the Vongola using his strength, and follow their sins, to which Tsuna told him that he did not want a Vongola like that, and would destroy the Vongola if he had to continue the tradition.When he, along with the other Guardians, was finally freed from Daemon's illusion with Hibari's help, Daemon challenged him to a direct combat and used his alternative weapon with Tsuna fighting him alone without any guardians' interference. During the fight, Daemon stated that he could not let the Vongola Famiglia fall apart because of Tsuna's foolish thoughts. Tsuna understood this, but said that he only fought to protect his friends, much to Daemon's annoyance, after which he started to attack the girls, but Tsuna managed to stop him. He then trapped Tsuna in his illusion while he was preparing a weakened X-Burner, but was tricked by Daemon, so that he launched the X-Burner to the girls. However, Mukuro immediately switched with Chrome and blocked the X-Burner with his trident. After some short conversation between Daemon and Mukuro, Tsuna attacked Daemon and finally managed to use his X-Burner on Daemon with Mukuro's aid. Daemon appeared again, but no longer had any intention to fight, and decided to deem Mukuro worthy of his inheritance, to which Tsuna replied by saying thank you, much to Daemon's surprise. Tsuna was then ready for Giotto's test; however, Giotto had already accepted him because he had been watching him when his Guardians were struggling to gain their inheritance and Tsuna always thought of his Guardian's well-being before his own, which fulfilled all of Giotto's expectations for him, and so, Giotto granted his inheritance. The next day, he and the others gathered at Namimori Shrine and returned to the Future for the final battle with Byakuran. Six Funeral Wreaths, Tsuna saves everyone after defeating Ghost the Lightning Funeral Wreath, he fought Byakuran,who showed up at the scene with his powers transported by Ghost. During the fight between Byakuran he was momentarily defeated, but after some words from Reborn he stood back up and told Byakuran he didn't regret anything and would give his life to protect everyone and suddenly Vongola Primo appeared. Vongola Primo then explained to him that the Vongola Rings aren't at their originally full power and that it had its highest Flame output restrained so that it can be safely passed down to their proper successors. Vongola Primo then entrusts Tsuna and changes his and his Famiglia's Vongola Rings back to their original form saying "the current form of the Vongola Ring is only temporary", and that he believes that he will understand the true meaning of both the Ring and his will. Vongola Primo told Tsuna to "Give That Mare Boy (Byakuran) What He Deserves" before leaving. Byakuran then says what a fool of an ancestor he has. Tsuna then continued fighting Byakuran, overwhelming him with his new increase in power and revealed that both his Vongola Box's Cambio Forma had changed shape, their power also increasing to a higher velocity. Byakuran notices that Tsuna's reflexes are fast. Tsuna then overwhelmed Byakuran with his new power and ripped off both his wings, asking if he was reduced to nothing without his wings. Byakuran then gets up laughing stating that he's happy that he can fight someone at full strength. Byakuran and Tsuna fight it out to see who won and Yuni was preparing to sacrifice herself to revive the other Arcobaleno, Tsuna tried to convince Yuni out of it but she had already decide while outside the barrier the other try their best to stop Yuni from sacrificing herself with the help of Alfin , Basil's Box Weapon and the rest of the Vongola Boxes and Varia Boxes ,Basil was able to crack the barrier for Gamma to leap in and talk to Yuni and said that he is willing to help Yuni revive the Arcobaleno. In the end,both Yuni and Gamma were sacrificed, but the revival was delayed and Byakuran blamed Tsuna for killing Yuni and said that he had ruined his plans to obtain the Tri Ni Set, Tsuna countered that it was Byakuran who made the world this way which caused Yuni to sacrifice herself. Both of them then prepared to use all of their power to see who will dominate this battle. Tsuna fired the X-Burner and Byakuran was unable to stop it and had a flashback where the Cervello approached him and gave him the Sky Mare Ring and after that Byakuran was incinerated and leaving the Sky Mare Ring on the ground,colourless. The Arcobaleno then revived and promised to send Tsuna and the rest back to the past. After Tsuna and his friends return to the past, the arc ends with Tsuna's future self looking at his coffin.
Before Tsuna and the rest went back to the present, an earthquake occurred. Because of this, 7 students from the Simon Middle School transferred to Namimori Middle School. They were P. Shitt, Kaoru Mizuno, Koyo Aoba, Julie Katou, Adelheid Suzuki, and Enma Kozato. They belong to the Simon Famiglia and are guests to Tsuna's Inheritance Ceremony. Not only that, but Reborn receives a letter from the 9th Boss about Tsuna officially inheriting the Vongola Famiglia.
As the days go by, Tsuna, on his way home from school, sees Enma getting bullied; Reborn pushes him into the fight leading him to get beaten up as well. After this incident, the two begin to talk, and unexpectedly their rings begin to resonate with each other, and Enma runs away accidentally dropping his books in the process. Tsuna catches up with him, as he was trying to return the books, and in a display of both their clumsiness, fall into the river. They then go to Tsuna's house to dry off.
This incident makes the two realize that they had a lot in common, and they soon warm up to each other. During the next few days, Tsuna finds out that Enma's group are actually members of the Simon Famiglia, and had come to attend Tsuna's inheritance ceremony. The two families start to bond with each other and does activities to support each other.
As the day of the Ceremony draws nearer, Tsuna has a meeting with the 9th, who puts Tsuna under no pressure to accept his role, simply telling him that it was his choice. But the 9th did explain a little bit about the history of the Vongola, and tells Tsuna to think about what he should do before making a decision.
Tsuna, who was a bit confused as to what he should do consults with Enma about his conversation with the Ninth. But Enma, seemed a bit agitated and told Tsuna how he and his Famiglia had to deal with a lot of abuse from other Mafia Famiglias because of their status. However, he said that Tsuna was different from the other scary mafia people, and he feels he can be friends with him. Enma, after his conversation with Tsuna, calls Adelheid, and tells her his opinion on Tsuna. Adelheid asks Enma to test Tsuna, and Enma responds by writing a letter to Tsuna, telling him that he had been captured by the enemy, and asking Tsuna to come help him. However, Tsuna never got a chance to see this letter, as a wind blew the letter away, leaving Enma to be alone, feeling betrayed, in an abandoned factory yard.
Later, Tsuna visits the 9th once again, to give him his answer. Tsuna declines the role of the Vongola Boss, and as he was preparing to leave, gets an urgent call from Gokudera telling him that Yamamoto had been attacked, and was in critical condition at the hospital.
Reborn and Tsuna both hurry to the hospital, where the doctor informs them that even if Yamamoto were to survive, he would most likely not walk again. However they soon learn that after Yamamoto was attacked, he had left a message written in his own blood, as a warning.
After asking the Simon to leave, Reborn explains that the word that Yamamoto had written "Delitto", means "Sin", and goes on to explain a tradition of the Vongola, and the Vongola Sin. Reborn asks what Tsuna wanted to do, and Tsuna determined to catch the culprit, asks Reborn to tell the 9th to go ahead with the ceremony.
On the day of the ceremony, the culprit attacked the Ninth and managed to wound him, destroying the Sin; however, the broken vial turned out to be a fake, and the real Sin was being held in a Dying Will safe that couldn't be destroyed by any weapon or Dying Will Flame; however, the Simon Famiglia managed to break it and take the sin, proving that they were the ones who attacked Yamamoto and the Giegue Famiglia. Enma then revealed that the Sin was originally the Simon's, and that they transformed with its power. Tsuna then goes into Hyper Dying Will Mode to fight Enma. When Tsuna asks why the Simon Famiglia attacked Yamamoto, Enma replies that he was a Vongola Guardian and that it was ``rightful atonement``. Enma then went on to explain that the Sin belonged to the Simon Famiglia and that it was the blood of their first boss. Adelheid tells the story that during Vongola Primo's time, the Simon and Vongola Bosses were as close as brothers, but when the Vongola planned to take over Europe, they used the Simon Famiglia as bait.
Timoteo says he never heard that story. Enma then asks Tsuna if he's ever heard the story since he is carrying the blood of Vongola, which Tsuna replies, he swears upon his grave that Vongola Primo is not a man who would do such a thing. This angers Simon and they make the declaration that Enma will inherit their Famiglia as the tenth boss and take revenge of the Vongola by gathering mafia from all over the world and standing above them as leader. The purpose of the war was to gain back the pride of Simon. Adelheid and the others then release their rings as Enma says that the reason that Vongola Primo got rid of Simon was because they had a power that rivaled the Seven Flames of the Sky, which is the Seven Flames of the Earth. Alone, Enma defeated Tsuna's Guardians (excluding Lambo and Yamamoto) and broke their Vongola Rings with ease, which enraged Tsuna and he attacked him. He asked why he was doing this, which Enma replied that it was his own fault. He told Tsuna that the power of the Simon Famiglia is not yet complete and it is only at a seventh of it of its full power. Enma decided that he will leave for now since he only wanted to show the Vongola the living hell and immediatley defeated Tsuna and broke his Vongola Ring and Tsuna become unconscious. Tsuna start to feel regret commented that he can't even fight back. However, Talbot came and said there is still hope to repair the Vongola Rings and it can be upgraded with Tsuna's and the others Vongola Box Rings and the blood of Vongola Primo, "Penalty", and have a power like never before. However, if they fail, the Vongola Rings will lose their spirits and will never shine again. Talbot then asked Tsuna what will he do, Tsuna hesitated for a while, but he want to get Simon back for having done that to Yamamoto and also want to save Chrome no matter what it takes, Tsuna become determined and agreed to upgrade the rings.
After finding the location of the Simon Famiglia base on an unmapped island, the Ninth gives the task of subduing Simon to Tsuna and his guardians, with Reborn along as an observer. Before leaving, Shoichi sends Tsuna a package telling him how both he and Spanner got visions from past and in the package are new contacts and headphones from Spanner. After arriving on the island and meeting the Simon Famiglia again, the Vindice intervene. They explained that the Simon and Vongola should never fight each other, but if they did, because of the oath between the founders of each Famiglia, the losers would be locked in Vendicare Prison forever. After agreeing to the fight, Enma explains that they will be ready for their goal in six days and they return back into their base. Tsuna activates his new X-Gloves and tries to give chase, but finds out they have vanished. After searching the island they eventually come upon Koyo Aoba and he and Ryohei agreed to fight with their pride as a boxer on the line. However, since their battle eventually ended in a tie, the Vindice arrived and took both of them.After the first key is seen, Tsuna is sadden that Ryohei was taken, but Reborn states, that Ryohei came on his own accord, and that he should follow Ryohei words, and protect their pride. They then rest, where Lambo is led to an island surrounded by lava and Rauji also on the island, challenges Lambo to fight, while Tsuna, Gokudera, and Reborn are hopless to stop it. When Lambo awakened his Vongola gear, Tsuna was amazed and glad that Lambo was not completely defenseless. But when Rauji pushed Lambo into the lava he was distressed, but was relieved when he saw 15-year old Lambo. He later stated his guilt of forcing Lambo to fight, when he was rebutted by Lambo, stating that he was happy that Tsuna took him everywhere and wanting Tsuna to continue doing so. After Enma revealed to Tsuna that Tsuna's father Iemitsu "killed" his family and sister, Tsuna suffered from shock to the point even one of Reborn's comedic attacks had no effect on him. However, during Hibari's fight and Daemon Spade's revelation, and after receiving the fourth and fifth keys that revealed Giotto never betrayed Cozarto, Tsuna is determined to defeat Daemon Spade who has manipulated the Simon Famiglia from behind the scenes and save Enma and Chrome, finally coming to terms with his own weakness, stating that he will never lose to his own heart anymore and he will believe in Iemitsu to the very end. When he and the others arrive at Enma's throne inside the underground castle, he confronts Enma and tries to reason with him but to no avail, because Enma has already been consumed by hatred and only has the desire to mainly kill Tsuna for revenge. Tsuna then tells everyone to leave everything to him before he charges at Enma. Just as he is about to be sucked in by one of Enma's black holes, Tsuna commands Natsu to transform and managed to evade it. As the battle progresses, Tsuna's voice finally reaches Enma who then snapped out from the Simon Ring's control before remembering that Cozarto was never betrayed by Giotto. However, Enma is unable to control his own power and creates a huge black hole that will suck everything including himself. Tsuna refuses to run away and vows to save him, using XX Burner from his both hands and blasts it to the black hole, saving Enma in the process. Enma asked what Tsuna's pride is. Tsuna explains that Hibari has given him a hint and he learns that pride is something that could never be given up. He confidently and sincerely answered that his pride is his comrades, his friends. In the middle of their reconciliation, the Vindice appears and decides that Enma was the loser and gave the Sixth key, a clear pacifier. After witnessing the memory, Reborn questions the Vindice why did they have the pacifier. The Vindice refuse to answer, which makes Reborn somewhat bothered by it. Tsuna is surprised to see Reborn being this bothered for the first time and wonders if there is a secret behind the clear pacifier. The Vindice tells them that as the Simon Boss, Enma must watch the battle until the end and after the final Guardian's battle, he will be imprisoned. This makes Tsuna realize that the last Guardian battle would be Chrome against Daemon Spade. Tsuna and the others arrived when the fight is over; they're shocked to find that Mukuro has already defeated Daemon. After Mukuro left Chrome's body, Tsuna saved her from falling flat onto the ground. Later, the group is shocked when Mukuro, now possessing Mukurou, said he can't return to his original body because Daemon took over his body while Mukuro was possessing Chrome. When the Vindice arrived, Tsuna and Enma made a deal with them that if they defeat Daemon now in Mukuro's body the Vindice will negate the war between the Simon and Vongola and free the guardians from the Vendicare Prison. Once the battle with Daemon began in earnest, Tsuna was saved from being captured into Daemon's illusionary space. He later witnessed the brief showdown between Daemon and Hibari and was surprised to learn that Daemon not only could utilize the six Rings of the Earth but also the Vongola Gears as well. After Hibari was also sent to the illusionary space, Tsuna went into Hyper Dying Will Mode and charged at Daemon. However, he was quickly overwhelmed by a combination of the Storm and Lightning Vongola Gears until Enma joined the fight. After learning that Daemon was the true perpetrator behind the death of Enma's family, both Tsuna and Enma were determined to take him down. Without prior planning, the two bosses of Vongola and Simon became the "Hyper Duo" and combined their attacks to damage Daemon. When the smoke cleared, they were surprised to see Daemon use another Vongola Gear to lessen the damage.When the battle took a turn for the worst, Tsuna was faced with the decision of sacrificing Enma to defeat Daemon. While he was hesitating, Chrome stepped in and protected Enma, with the support of Mukuro, thus allowing Tsuna to fire XX Burner at its full potential. The attack drained Tsuna of every last ounce of his energy, but Daemon managed to survive. The situation
turned even more dangerous when Daemon began his attack on the helpless Tsuna. Just as Daemon was about to strike the finishing blow, the Simon Ring flew off and merged with the Vongola Ring. After the union of the Vongola Ring and Simon Ring, the Seventh Key was shown to the all guardians and Daemon. It contained the last piece of memory of Cozarto and Giotto and revealed the oath between the two bosses. After the vision, the Flame of Sky and Earth united to form the Flame of Oath. Tsuna used the special properties of the flame to repair his broken bones and enhanced them with a coat of Gravity. He then proceedes to overwhelm Daemon with the Flame of Oath. With determination in his eyes, Tsuna challenged Daemon to the final showdown. With the new gained power of the Flame of Oath, Tsuna manages to easily overpowers Daemon and about to finish him off when the latter intended to run away using the attribute of Vindice. However, Tsuna against this and instead tells Daemon to give in and atone for his sins. Daemon refuses this and two of them clashes each other until Daemon leaves Mukuro's body and about to escape through the portal. However, Bermuda interferes and dismisses the portal since it could only be entered by someone with physical body. With the opportunity he has, Tsuna blasts X-Burner at Daemon's soul. As Daemon's soul slowly begins to fading away, the pocketwatch that he always kept with him fell and opened. Tsuna picks the pocketwatch and sees with a sympathy like expression the photograph of Vongola Primo and his Guardians with a woman cuddled close to Daemon.Daemon, who's on the verge of death, says that the woman is his lover, Elena. He explains that he used to be an aristrocat who despised his own status for not becoming a backbone of society, an ideal shared by Elena, a duke's daughter who then introduced him to Giotto. Together, they joined the Vongola. Daemon reveals how he loved the Famiglia at that time until Giotto decided to disband his military forces to avoid fighting for selfish ambitions. This move left their territory open to attack and, as a result, Elena was killed in an ambush by the enemy forces. To fulfill his promise with Elena, Daemon swore to make the Vongola she loved stronger. After hearing this, Tsuna wonders does Elena truly like the Vongola that way, angering Daemon who then questioned does Tsuna understand how Elena feels. Seeing that Daemon could die soon and not wanting Daemon to die while still bearing hatred and regret, Tsuna answered he did, surprising Daemon. Tsuna lied that he could feel it with the Vongola Hyper Intuition that Elena feels gratitude towards Daemon and she would have probably thanked him. Hearing this, Daemon starts to cry as he begs for Elena's forgiveness for unable to save her back then. As Daemon's time came, Reborn assured Daemon to leave the Vongola to Tsuna, since Daemon should already know that Tsuna is not weak. Finally at peace, Daemon accepted Tsuna as the true Vongola Boss and dies, but not before telling him not to bring shame to Vongola's name since it's the Famiglia that Elena loved. Afterwards, Tsuna comments that Daemon saw through his lie about the Vongola Hyper Intuition and Reborn added that the reason Daemon continued to live most likely was to hear the same words that Tsuna told him from Elena. Tsuna and the others are overjoyed when Gokudera, Ryohei, Lambo, Yamamoto, and the Simon Guardians are freed and they are reunited, but then are interrupted by the Vindice, who tells to entrust them with the last key left by Giotto and Cozarto. The memory explained how the Simon according to the oath made with Giotto, decided to live away from the rest of the world in order to fool Daemon's eyes. When asked by their Famiglia about how right this decision was Cozarto answered that this sacrifice was for the sake of the future generations to come, for both, Giotto and Cozarto hoped for a future where their both families would be able to smile together again. And so, this was reflfected in the tenth generation which some weeks after the incident, both Enma's and Tsuna's Families were again at school together as friends, living their lives in peace.
Tsuna began to wonder the true nature of Arcobaleno and decided to ask Reborn directly about it. The next day, he and the others were surprised to found out that Chrome had been transferred to Namimori-Middle and surprised even more when she suddenly hugged Kyoko and cried. At the rooftop, it was then revealed that Mukuro had abandoned her. According to what Kyoko heard, when Chrome awoke in the morning she found a letter that tell her to get out and a Namimori-Middle uniform and Kokuyo Land empty. Tsuna questioned Mukuro's action, which Gokudera concluded that Mukuro no longer need her since he's already free, though, Tsuna doubts it.
At this time, Reborn arrived and told them that they had to accept Chrome in Namimori. Tsuna asked where he had been since morning. Reborn replied that Mukuro convened him to talk about Chrome and explained that Mukuro and his gang had gone to France to recruit Flan and meanwhile, he left Chrome in Namimori. Tsuna asked again why he only leaving Chrome but Reborn himself doesn't know but he had received her living expenses and for a meantime, Chrome will stay at Kyoko or Haru's place. After deciding they will throw out a party for Chrome, Tsuna asked Reborn about the Arcbaleno and Reborn said that it's about time that Tsuna knew everything. However, he added that he still want to make sure Tsuna's growth by winning mimicry game at Chrome's party, making Tsuna thought that Reborn had fooled him again. He watched the mimicry game with the others and then felt sympathy for Chrome and wondered that if he knew Arcobaleno secret, he somehow felt that the everyday life that they had will lost and might be better that he doesn't know anything. When it was Tsuna's turn to mimic, Tsuna tried his best to mimick Leon but Leon gave him 0 points as the result.
Later, Reborn requested Tsuna to do a favor for him, which Tsuna at first denied, thinking that Reborn would have him do something tedious. However, after Reborn explained his dream with the rest of the Arcobaleno and the curse of the Arcobaleno, Tsuna agreed alongside Dino, stating that teaming up with Dino made him feel reassured.
The next day, on his way to school, he along with Reborn, Gokudera, and Yamamoto were confronted by Kokuyo Junior High Gang, who declared war against Tsuna and Guardians as Mukuro stated that he would defeat Tsuna and destroy Vongola Famiglia. Tsuna refused this declaration, saying that he don't want to fight anymore. However, Mukuro revealed that he and his gang had became Verde's representatives for the upcoming Arcobaleno battle and thus, their fight cannot be avoided.
Tsuna and Reborn then head to Dino's hotel together, where Tsuna is subsequently taken to Xanxus's room in the hotel by Belphegor. As Xanxus makes threats to Tsuna and his team, Wonomichi arrives and announces the start of the Representative Battle of the Rainbow in four days.
1st Day of Representative Battle of the Rainbow
Later, as the first day of the the Representative Battle of the Rainbow arrived, Tsuna was at first nervous, but then felt at ease when he noticed that his friends were acting normally and hoped that they day would continue that way. After school, however, the wristwatches announced the start of the Representative Battle, and during his way out of the classroom, he encountered Iemitsu, who prepared to battle him, stating to Tsuna that it was time he himself should treat him as an adult.
As the battle starts, Tsuna has various regrets about facing his dad; however, he quickly gets annoyed by his dad's responses to his worry and prepares to fight. Tsuna charges at Iemitsu, punching him, but Iemitsu appears unfazed. Tsuna punches even harder, this time activating his Cambio Forma Version X, but it still isn't enough. Iemitsu casually enters Hyper Dying Will Mode and tells Tsuna to watch carefully, as what he was about to do was a real punch; he then proceeds to punch Tsuna away through the ceiling. Tsuna, after landing, appears to be unconscious. Reborn, Tsuna, Dino, Gokudera,Yamamoto, and Ryohei gather around a table in Namimori Diner to discuss the results of day one of the Representative Battle of the Rainbow. Tsuna sadly recounts how his dad beat him with one punch, but didn't destroy his boss watch. Reborn explains that he made a deal with Iemitsu- if Iemitsu didn't destroy Tsuna's watch, they would make an alliance with Colonnello's team. Suddenly, all of the boss, representative, and Arcobaleno watches start speaking. The speaker congratulates all of the participants and introduces himself as Checker Face.The watches then display the results of the first day's battle.Team Reborn concludes that they had to watch out for Team Verde. Gokudera suggests that they skip school to not participate in the battle, but Reborn states that he didn't want their schooling to suffer from the battle. Dino also expresses his guilt that he didn't fight with them in the first battle, and that he should stay nearby their school. Reborn, however, just tells him and Romario, whom he called over, to search for two remaining representatives.
The group leaves Namimori Diner, and Tsuna is troubled, mentally commenting that he didn't want to return home to see his dad after such a devastating defeat to him. Yamamoto, seeing his troubled state, invites him to go over to his house, as he had just bought a new baseball game. Gokudera opts to go over to, just in case someone attacks Tsuna in the middle of the night, but expresses his excitement over Yamamoto's sushi restaurant.
2nd Day of Representative Battle of the RainbowThe next day at school, Tsuna expresses his shock at Enma's announcement that he and his fellow Simon Ring Holders had become part of Team Skull. As class starts, Dino walks in and introduces himself as their new English teacher. On the balcony as they regroup, Reborn states that they had to go get some "valuable intel". They head to a mansion in the middle of a forest where Reborn states that one of their allied teams knew some information about Team Verde. When they arrive, Yuni greets them cheerfully, opening the door. Inside, she serves them tea as Bluebell and Nosaru stick their tongues at them, Yuni mentioning that she had got to know them really well and that she hung out with them a lot. Yuni explains that Tazaru, Torikabuto, and Daisy all had their watches destroyed by Team Verde. Yuni reveals upon Tsuna's question that her Arcobaleno Curse was a short life. Tsuna expresses his concern, but Yuni tells them to fight for Reborn with all their strength, for two teams would be eliminated in the second day of the battle. Once more at Team Yuni's rented mansion, Byakuran reveals that he had found a counter to Verde's machine, stating that they would fight genius with genius and machine with machine. Spanner and Shoichi then show themselves and Byakuran recalls his future self's encounters with the two geniuses with a smile on his face. Spanner and Shoichi greet Tsuna. Suddenly, the wristwatch beeps and announces one minute until the battle starts. All of Team Yuni's members rush to their room, ready to fight, and Reborn notes that Team Verde was about to arrive. Byakuran answers Tsuna's question that he was Team Yuni's boss representative and flies out into the sky with his wings, Tsuna following him by entering Hyper Dying Will Mode, propelling himself with Sky Flames from his X-Gloves. However, the wristwatch announces the battle this time to be 30 minutes long as it commences the battle.
24 minutes and 30 seconds of the battle remain. Tsuna and Byakuran are up in the sky keeping a lookout for enemies. Tsuna questions Byakuran why he, who killed thousands in both the future and parallel worlds, was fighting with all his heart for a single Arcobaleno. Byakuran simply explains to Tsuna that he was like him back then in the future, willing to fight for Yuni. As they are talking, Team Verde attacks. Tsuna flies to Mukuro and attempts to stop him but much to Tsuna's frustration Mukuro taunts him which causes him to lash out fiercely, still feeling insecure after the tragic defeat from his father.
Meanwhile, Colonnello had released his curse and was planning to snipe Team Verde and Team Uni. As Mukuro and Tsuna continue to fight Colonnello fires his Maximum Rifle. Simultaneously, Ken, Byakuran, Mukuro, Chikusa, Flan, Gamma, and Kikyo are hit as Team Reborn's members watch in a mixture of shock, awe, and horror. Lal Mirch announces that Kikyo, Ken, and Chikusa had been eliminated, continuing to announce that although they were unable to confirm Gamma, Byakuran, Mukuro, and Flan's watches' destruction, they had all suffered injuries from trying to protect their watches. Iemitsu contacts Tsuna through his X-Headphones to check if he was alright. lemitsu tells Tsuna to get as far away from the battle as possible, as Colonnello was going to fire a shot that would eliminate Byakuran and Mukuro, eliminating Team Yuni and Team Verde. Tsuna refuses to allow them to hit Byakuran, so lemitsu announces that the alliance between them had been officially terminated and that Colonnello would be firing at them as well in the next shot. lemitsu tells him that if they were going to stop them from eliminating Byakuran, then he had to re-assess their alliance, telling Tsuna to quickly make his decision, as he wouldn't wait much longer. lemitsu asks Tsuna on the course of action, and Tsuna tells Iemitsu to shoot. Tsuna then activates Mitena di Vongola Primo and tells his teammates to prepare for the second shot. lemitsu tells Colonnello to shoot. Lal Mirch isn't sure about the shot, but Iemitsu tells him that his un-cursed time couldn't go to waste, and to shoot. Colonnello fires Maximum Rifle. Tsuna charges and so does Gamma. Yuni cries out in anguish but Reborn rushes to stop the attack, mentally saying that Gamma was useless in this situation and that Tsuna would be defeated at this rate. As Tsuna, Gamma, and Reborn are all about to be hit, Byakuran intervenes, stating that they couldn't lose. Tsuna asks why, and Byakuran reveals that despite his dreams in the future, he was only awaiting death. He mentions how Yuni became the warmth of his life, and states that this time, he would be the one to protect her heart. Byakuran then tells Tsuna to charge and defeat his father.Byakuran falls to the ground, heavily wounded and his Rainbow Wristwatch destroyed, signifying Team Uni's defeat. Tsuna rushes towards lemitsu to avenge Byakuran, saying he will never forgive lemitsu. Iemitsu tells Colonnello to leave this to him and to save his un-cursed time, and Colonnello states, "Present, stop" and wishes Iemitsu luck. Tsuna punches Iemitsu into the ground, but the latter kicks the former, sending him hurtling back. Iemitsu comments to Tsuna that he hadn't improved at all, but Tsuna, enraged, tells him to shut up and slams him into the ground again. However, Iemitsu appears to be unfazed and slams Tsuna into the ground next to him. Tsuna wonders, in his pain, why he still couldn't beat Iemitsu. Tsuna recalls how Iemitsu left him and Nana in their house all alone, how he, when he returned, would only sleep or talk about meaningless things. Iemitsu, now sitting beside Tsuna, apathetically states that it was boring fighting with him. Tsuna exits Hyper Dying Will Mode and bursts out at Iemitsu if he was insulting him. Lal Mirch notes that since Tsuna's exited Hyper Dying Will Mode, his willpower and energy had collapsed. Iemitsu, meanwhile, doesn't respond and Tsuna repeats the question furiously, but Iemitsu still doesn't respond and tells Tsuna to take of his boss watch so that he could destroy it. Tsuna refuses, so Iemitsu lifts a boulder and hurls it at Tsuna. Colonnello and Lal Mirch shout out that it was going to crush Tsuna. However, Tsuna is saved by Reborn in the nick of time, who was in his curse-released time. Reborn shoots the boulder and destroys it into letters, spelling out the word "C-H-A-O-S" and they land around Tsuna. Iemitsu appears to be shocked, and Lal Mirch and Colonnello chorus in unison that there was only one person who could pull off a feat like that. Reborn, in his curse-released form, stands before them, with his hat shading his eyes. Tsuna asks Reborn who he is, not recognizing him in his adult form. Reborn looks at Tsuna with a hard expression and tells him that it was lesson time. Reborn easily heavily injures Iemitsu while in his un-cursed form, Tsuna being oblivious to the adult Reborn's identity. Reborn tells Tsuna two weaknesses of his for when he has to fight Iemitsu again. When Reborn runs out of his un-cursed form time, Tsuna is still oblivious to Reborn's identity when Reborn changes into his cursed form right behind a boulder. Reborn reminds Tsuna of his un-cursed form's lesson, which Tsuna takes into mind, and fights Iemitsu. Tsuna's skill and speed have suddenly improved, which Iemitsu notes, and Reborn mentally tells Tsuna to show him what his student was capable of.
Tsuna uses Zero Point Breakthrough: Revised and absorbs Iemitsu's Flames. Colonnello and Lal Mirch note that Tsuna's Flame combustion power was increasing. Tsuna finishes absorbing the Flames of Iemitsu's attack and pushes himself back, then propels himself with his X-Gloves towards Iemitsu once more. Tsuna and Iemitsu trade blows, but ultimately Iemitsu grabs hold of Tsuna's leg. Tsuna quickly reacts and thrusts his hand towards Iemitsu's face and uses X-Burner at point-blank range, much to Iemitsu's surprise, though he manages to escape. Suddenly, their Rainbow Wristwatches beep out and announce the end of the second day's battle. Tsuna and Iemitsu stop their battle and Iemitsu compliments Tsuna, stating that he was sincerely trying to break his boss watch at the end. Iemitsu comments that the battle was fun, angering Tsuna, who scolds him for taking the battle un-seriously. Iemitsu once again comments that Tsuna sounded just like Nana. Tsuna, despite that, tells him that he would win next time, Iemitsu responding with an "OK." Tsuna once again wonders who the man in the suit was, when suddenly Gokudera and Yamamoto arrived, having arrived here by bike by propelling themselves with Gokudera's bombs.
Gokudera and Yamamoto congratulate Tsuna on his tie with Iemitsu. Tsuna says modestly that it was all thanks to the mysterious man in the suit, which Reborn reacts with a glint in his eye. As Iemitsu asks Lal Mirch on the other teams' situation, Basil's voice comes through her headphones, frantically saying that things were bad and to connect him with lemitsu immediately. Basil had been spying on Team Skull when a large group of Vindice led by the Vindice Arcobaleno had attacked all of the members of Team Skull, leaving them mortally wounded. Skull had been attacked and wristwatch stolen and changed to Bermuda. Team Reborn is informed of the unfolding events until suddenly Checker Face announces the accumulated results for the second day. Tsuna and his representatives rush to Namimori Hospital to see of the Simon were alright when they meet an upset Basil who reassures them that they would make a full recovery. Suddenly, Kyoko arrives and states worriedly to Tsuna that Chrome was unwell and her internal organs were gone. She tells him that Chrome had been calling out for "Boss." Tsuna rushes to Chrome along with Kyoko. Tsuna apologizes for not noticing her condition earlier, but is cut off by Chrome who requests to join as a representative for Team Reborn. Tsuna firmly refuses for her well being.
Later in Yamamoto's dad's sushi shop, Gokudera and Yamamoto commend Tsuna on his decision, stating that Reborn would have done the same. Gokudera wonders where Reborn was, to which Tsuna answers that he was apparently meeting with the other Arcobaleno to discuss Bermuda. Suddenly, however, everyone notices an ominous Flame. As Reborn returns from the meeting, he finds Tsuna, Gokudera, and Yamamoto battling a Vindice member. As soon as Reborn reaches them, the Vindice vanishes. Afterwards Team Reborn's members discusses the day's events, and Reborn triumphantly states that he had found a new representative.
3rd Day of Representative Battle of the Rainbow
At exactly 12 A.M., the watches signal the start of the third day of battle. Tsuna expresses his shock that the third day was starting so soon. They quickly get changed and run to the playground to avoid involving the locals getting involved. Team Reborn runs into Mukuro and the rest of their team. Reborn questions his presence, but Mukuro dismisses the question and comments that the situation was fortunate, as he didn't need to waste time finding them. The Rainbow Wristwatches announces the start of the third day of battle, the time limit being 12 minutes. Ken confidently announces that he and Chikusa had spare watches. As with the other battlefields, 3 Vindice arrive on this battlefield. The Vindice suddenly attack Mukuro with their chains, creating an enormous explosion. Each team's representatives call out to their bosses, worrying about them. As the explosion's smoke cloud clears, Mukuro and Tsuna agree to temporarily team up, with their strongest weapons at the ready. With Flan sleeping, Mukuro Rokudo and the rest of his gang decided to team up with Tsunayoshi Sawada and his team to defeat the three Vindice members. Gokudera unleashed his Sistema C.A.I. to shield them from the attack of the Vindice. They group members work together using combined attacks. Tsuna uses Hyper X-Stream as Mukuro summons corpse eating crows to devour the Vindice. After the explosion destroys Vindice's hats and coats, they reveal their faces. Everyone was shocked to see Pacifiers hung on their necks.
Mukuro and Tsuna comment on the zombie like appearance of the Vindice, who proceed to praise them for their valiant effort and attack them again, refusing to reveal any information. Tsuna fires with X-Cannon to distract so Mukuro able to finish them off. Mukuro is unable to do the combo move of Genjuu Gagaia, as Fran is still asleep and the Vindice easily deflect his attack. Realizing that they were overwhelmed, both teams started to lose hope. At this time, however, Chrome Dokuro appears as Reborn's representative and offered to support Mukuro's illusion to help them.
Chrome arrives on the battlefield and Tsuna expresses his surprise as she is still without organs but had still managed to arrive to fight. Verde equips Flan's equipment onto Chrome to do the combo move in Fran's place. Tsuna grabs Mukuro by the shirt and demands why he had not supported Chrome with his illusionary organs, and it is revealed that Chrome had been refusing Mukuro's illusions. After they stopped sharing one body, Chrome began to change and expressed her desire to be seen as an individual, and not just Mukuro's replacement. She makes her resolve to protect everyone she loves and generates a powerful Flame, recreating her illusionary organs in the process. With her energy regained and her resolve found, Chrome combines her strongest illusion with Mukuro's and creates Genju Mugaia.
Mysteries of the Arcobaleno
With the majority of the Vindice defeated, Tsuna proceeds to fight the remaining Vindice. Reborn realises he is protecting the boss watch and yells at him not to care about it and to fight with his dying will. Tsuna successfully defeats the Vindice and Reborn reveals his true motive for entering the Representative Battle, which was because of Tsuna's bad grades. Suddenly Bermuda requests to speak with Reborn and sucks him into a black hole, and Tsuna flies after him only to be sucked in too.
They land into a cave, which had ominous carvings of the Arcobaleno cycle. The engravings on the cave walls tell the story of how the strongest people of the era are taken to a mountain and turned into Arcobaleno, doomed to protect the pacifiers until they cannot be used anymore and a new cycle of the strongest people begins. Jager and Bermuda arrive and further explain that the Vindice were in fact what became of Arcobaleno- if they survived the removal of the Pacifiers. Bermuda also reveals that the curse wouldn't be removed; it was just a farce to gather the seven strongest people. Bermuda asks Reborn to assist him to destroy the Arcobaleno system by killing Checkerface, but in the process all the Arcobaleno will die. Suddenly Tsuna cuts in and yells that he would not accept it and he will find another way, which leads to a brief skirmish between the two parties.
Tsuna is losing, which causes Reborn to yell in panic. Bermuda uses this fight as an example and says that whether or not they assist him, they were all going to burn in hell no matter what is done and they exit. Reborn tells Tsuna in defeat that it was clear that he could not beat Jager in the first place, and he tells Tsuna to give up on him and the Arcobaleno. Tsuna expresses his dismay over Reborn's odd statement, shouting that it was weird that Reborn said he couldnt win as Reborn was the one who was always telling him he could. Reborn replies that those times he knew tsuna could win, but this time he cant. They leave the cave and Tsuna runs home in anger and despair, and decides to take initiative despite Reborn admitting defeat.
Tsuna arrives home and finds about lemitsu's injuries, and then attempts to sleep but cannot. He goes down to the kitchen and sees Lambo, trying to mix Basil's strawberry juice with his grape juice. Lambo proceeds to fill up the missing part of Basil's drink with his grape and claims it was perfect. Tsuna suddenly realizes by 'filling up the missing part' he could solve it. He quickly calls the 9th to ask for someones adress and enters hyper dying will mode. He goes to all the Representative Bosses homes and requests each of them to lend him their strength.
The next morning, Tsuna falls asleep against a wall. He is awakened by Kyoko, who greets him and asks for his good luck charm, as she wanted to add more prayers to it with Haru. When Chrome appears and leaves with Kyoko, Tsuna thinks of the conversation he had with Talbot the night before and their discussion on saving the Arcobaleno. Lambo had given Tsuna the idea of replacing an Arcobaleno's removed Flame with another Flame of the same type. Reborn interrupts Tsuna's thoughts and Tsuna takes him to Namimori Shrine. Reborn provokes Tsuna, causing him to go off on Reborn about giving up hope of living. After Tsuna finishes his rant, he exhaustedly sits down on a step and says that he will not let Reborn die. As he said this, however, Tsuna found Reborn fell asleep. He tried to wake him up but quickly changed his mind when remembering what he will do if he forcefully woke him up, leaving him no choice but to return home alone. Unbeknowst to him, Reborn just pretended to be asleep and was proud of his student even though he said that it still impossible to prevent him from dying.Tsuna visits Gokudera and Yamamoto at hospital, saying that he has something to discuss with them and he had told Xanxus, Mukuro, Byakuran, and Enma yesterday, much to Gokudera's dismay since he's a day late even though he's his right-hand man. Tsuna quickly apologizes and explains that since he had been dependant on his Guardians and Dino, he felt that they will help him anyway as he considers them as his family, apologizing that he should've told them first since they're friends, to which Gokudera and Yamamoto reply that they are family and there's no need for him to be formal. Tsuna thanks them and begins to explain everything he has heard yesterday from Bermuda along with his plan. After explaining everything to them, Tsuna goes to Dino and Hibari at Namimori Mountain and was shocked to find out that they've been fighting ever since the last battle with Mammon. They stopped, however, when Tsuna reveals how urgent the situation he's going to explain and they are shocked to know what will happen to Reborn and how powerful Team Bermuda is. After school, Tsuna gathered all people he has visited in his house and request for all of them to fight together, explaining everything about the Vindice, Checker Face, and information that Talbot has provided him as they arraning plans to defeat Team Bermuda.
4th Day of Representaative Battle of the Rainbow
Tsuna, along with Enma and Basil became the Commanding unit of the entire Allied Team. Tsuna decided to defeat the Vindice one by one, starting from Alejandro who comes alone while the other remaining squads prevents Jager, Big Pino, and Small Gia to leave from their places. The three of them encounters Alejandro and briefly fought Alejandro's dolls, Ginger Bread. With the three's teamwork, they able to easily defeat Ginger Bread and destroyed Alejandro's wrist watch, disqualfying him from the battle.
They immediately went to where Small Gia and Big Pino are, who were being occupied by Gokudera, Yamamoto, Chrome, and Flan. They arrived just in time to save the four right before Big Pino's attack hit them, fighting them in their place. While Tsuna and Enma managed to defend themselves from Small Gia's attacks, Basil, however, was defeated by Big Pino's attack. In anger, Tsuna attacks Small Gia, but the latter uses one of his weapons to make a flash that momentarily blinding Tsuna's vision. Small Gia was about to deliver a blow at Tsuna, but Yamamoto quickly seizes him from behind with Gokudera's dynamites in hand and Gokudera distracts Big Pino until he's close enough to reach his battler watch. With Enma's gravity manipulation that stopping the two's movements and with Chrome's and Flan's illusions, they were able to destroy Small Gia's and Big Pino's wrist watches without harming both Gokudera and Yamamoto.
Tsuna is often flustered by Gokudera's enthusiasm (which is only towards him), but sees him as a true friend. He even told Gokudera to abandon his Half Ring during his fight with Belphegor (as the circumstances would have ended up killing Gokudera). Future Tsuna apparently appoints Gokudera as his right hand man.
Initially, Tsuna clings to Yamamoto as one of the last bastions of normalcy in his life, otherwise dominated by violence and the Mafia, especially as Yamamoto continues to think that the entire situation is merely a gigantic role-playing game. Unfortunately for Tsuna, Yamamoto takes the "role-playing game" very seriously, and Tsuna often finds himself unwillingly dragged along by Yamamoto's seemingly misplaced calmness and confidence. However, Tsuna definitely sees Yamamoto as a true friend, albeit much more sensible than Gokudera; Tsuna seems to not have to worry about Yamamoto as much. Both also find common ground in their lack of effort at school, as both end up taking supplementary classes.
Yamamoto, likewise, views Tsuna as a friend, ever since Tsuna stopped him from committing suicide. He generally accepts Tsuna as the Tenth, and he seems fine with following Tsuna's leadership.
As Hibari is one of the most bloodthirsty characters in the series, Tsuna is never comfortable with him (often getting "bitten to death"). Nevertheless, Tsuna generally feels more confident when Hibari is around, due to Hibari's deserved reputation as an excellent and merciless fighter. On the other hand, Hibari generally is aloof to Tsuna, often describing him as a "herbivore." He avoids Tsuna and the rest of the Guardians due to his dislike of "crowds," and views them as weak and not worth his time. However, in Inheritance Ceremony Arc, before he fought Adelheid, he noticed Tsuna making a 'boring face' due to the mental shock he received and told him to watch his fight closely, which surprised Tsuna. This possibly means that Hibari has started acknowledging the current Tsuna. After he won the fight with Adelheid, he also mentioned that "it is the sky that allows the cloud to move about freely." as further emphasis of his recognition of Tsuna.
Tsuna is often flustered by Ryohei's passion, and the confidence Ryohei has in his strength. He is often roped into fights alongside Ryohei (often schemes to get Tsuna into the boxing club), leaving Tsuna wondering how he could be Kyoko's brother. However, Tsuna values him as a good friend, referring to him as an older brother. Tsuna also shows reluctance whenever Ryohei fights, due to how his injuries could affect Kyoko.
Even though Lambo often drives Tsuna crazy, he seems to deeply care for him. Evidence of this can be seen during the Varia Arc when Tsuna saves Lambo from Leviathan during their match for the Vongola Lightning Ring. However, during the Future Arc, Tsuna was beginning to succumb to the frustration due to their current situation and eventually snaps at Lambo and Haru saying that they don't know anything. They later reconcile when Tsuna apologizes to him. Tsuna always tries to put Lambo out of danger, believing it to be unfair for such a young child to be put to battle and always blames himself if Lambo is in a danger.
Tsuna initially hated Mukuro greatly for the horrible things he had done to his friends, in order to lure Tsuna out. After hearing about Mukuro's past from Ken, Tsuna lost his hatred towards him. Although Reborn often tries to remind him about those horrible things, Tsuna remains concerned over Mukuro's well-being, as seen in Future Arc when Tsuna knew that Mukuro is still trapped in the Vendicare Prison after 10 years. He does not see Mukuro much of an enemy and seems worried whenever bad things have occurred to him.
She seems to appear out of nowhere with Tsuna in some scenes, though it could be coincidence. She also seems to like Tsuna as he was the only one who trusted her to be his Mist Guardian out of everyone in the group for the Ring Battle and rewarded him with a kiss, much to his embarrassment. Despite Chrome's connection to Mukuro, Tsuna seems to see her as an important ally and even shows concern for her well-being, such as bringing onigiri to her during the Arcobaleno Trials Arc. He thinks of her as an important friend, as one of the reasons he went to battle Simon was to rescue, and is generally cares for her well-being, wishing that Mukuro would return, so Chrome would calm down
Family & Allies
Tsuna's mother, Nana Sawada, is a kind woman and a good mother who sometimes displays a paradoxical lack of concern for her son. She is very much in love with her husband, but, like many characters in the series, is oblivious to both Tsuna's and her husband's involvement with the Mafia. Despite the dangerous situations she and her son always seem to be embroiled in of late, she curiously is generally unfazed. Similarly, as with both her husband and her son, she seems to be accustomed to caring for and not giving up on people who others see as lazy and worthless layabouts. Tsuna's father, Iemitsu Sawada, is another story altogether. He has been absent for much of Tsuna's life and is viewed by his son as a lazy slacker and a deadbeat dad, although ultimately his character comes off as outrageous, taking ludicrous jobs and wantonly distributing alcohol. Although Tsuna thinks very lowly of him, his father seems to have great respect and high hopes for Tsuna's future, since he is the one who suggested making Tsuna the next Vongola Boss of the Vongola Famiglia. Despite his worthless appearance, Tsuna's father has also steadfastly provided for his family for years and pulls strings behind the scenes for his son, as well as being the head of CEDEF
Giotto is Tsuna's ancestor and the founder of the Vongola. Tsuna trusts Giotto completely and seems to hold him in high regards. He stands up for Giotto when someone questions his actions, like when Enma told Tsuna about Giotto's betrayal of Cozarto Simon. He stated quite confidently that Vongola Primo was not the kind of person who would do such a thing.
In turn, Giotto sees Tsuna as his true successor and has helped him when he seemed to be in trouble, such as in Tsuna's battle with Byakuran, where Giotto appears to unlock the true power of the Vongola Ring; something which he had not done for eight generations of Vongola Guardians, as he believes that Tsuna will understand the true meaning of the Rings and his will.
As the IX's most trusted assassin, Reborn was sent to Japan to educate Tsuna and make him a true successor of the Vongola Famiglia. Although Reborn is usually quite cryptic and hard on Tsuna he only has the best intentions. They have been through quite a bit together and have formed a bond of friendship that allows them to work very well together. Initially, Tsuna was wary of Reborn due to Reborn's involvement with the Mafia and often tried to avoid contact with him, due to Reborn's spartan methods of training, which more often than not involved Tsuna getting shot, facing danger, and humiliated. Tsuna was also often shocked by Reborn's random appearances in numerous costumes, his use of insects as a spy network, and his casual use of violence, though ironically he depended upon and looked to Reborn for help in numerous situations. Ultimately, the two form a close teacher-student bond that has brought about a drastic improvement in Tsuna's character and ability to lead the Vongola, something that Tsuna recognizes. This relationship has changed in recent times to more that of comrades-in-arms, though Reborn still largely remains a teaching figure. The true extend of their bond is finally shown when Tsuna lashed out at Reborn when the latter thinking that he would die a worthless death, which makes Tsuna felt not being trusted by his tutor and stated that he won't let Reborn die to the point of challenging him when the latter ask for him to return his boss watch and showing his resolve to save him and the other Arcobaleno, something that Reborn is proud of.
Haru has a deep one sided admiration for Tsuna that started when he saved her from drowning. She is a bit over enthusiastic towards Tsuna in the expression of her feelings towards him. Unlike Kyoko, Haru knew about Tsuna's position in the Mafia and seems to love him more for it. Unfortunately for her, while Tsuna sees her as a friend, he also sees her as a little crazy. During the Future Arc, Tsuna is seen yelling at her states that she doesn't know anything. Holding back her tears, Haru states that she is willing to listen but that Tsuna has never tried to explain anything. Though she leaves the room crying, they later reconcile after Tsuna apologizes.
Both are not in good terms, Xanxus hates Tsuna and never acknowledge him as the true successor of Vongola, which is why he and the Varia he leads only take orders from the ninth and he also the only one who refused to attend Tsuna's Inheritance Ceremony. Tsuna at first scared at him and think of him and his group as scary and prefered him to be the Vongola boss rather than him. However, this changed after he realized what kind of person Xanxus is especially what he did to the ninth and will never let him succeed the Vongola. However, despite this, whenever the Vongola was attack, both have no hesitation to work together as stated by Xanxus that the Vongola always fight as one.
Enma has demonstrated in multiple ways that he is similar to Tsuna; likewise, Tsuna thinks of him as a good friend. However, after Tsuna unknowingly failed the test he had set up, their relationship became strained, making Enma believed that Tsuna is no different from the cruel Vongola bosses. After Enma and his Famiglia stole the Vongola Sin, their relationship worsened, as Enma claimed that he would never forgive Tsuna and would no longer have any hesitation to kill him. Tsuna stated that he is also angry at Enma for making his friends suffer, and also for insulting Giotto, but he also symphatized Enma's past and current condition, as he still regards him as his friend. After witnessing from the fourth and fifth keys that Cozarto was never betrayed by Giotto and saved Enma from Daemon's control, they reconciled, becoming friends again.
Initially, Tsuna and Byakuran didn't have a good relationship in the future for what Byakuran had done to his family and friends and people close to him. Tsuna has shown numerous time of his desire to defeat Byakuran at all cost and this deepened after Yuni sacrifised herself to revivew the Arcobaleno and when Byakuran insulted her action, which angered Tsuna who then stated that he won't forgive him and led him to kill Byakuran. Byakuran has also shown his annoyance of Tsuna's interference in every parallel world. However, in the present, they seemed to be much on better terms, since Byakuran has a change of heart and even offered alliance with his team and even protected him when Tsuna almost hit by Collonnelo's attack. It is unknow whether Tsuna has forgiven him or not for what he had done int he future, but Tsuna seems to regard him as his one of his comrades after they fight together during the secondd ay of Representative Battle of the Rainbow, and showed concern when Byakuran was injured by Collonnelo's attack, prompting Tsuna to promise he will defeat his father. Though, sometimes Tsuna found Byakuran's cheerful attitude to be odd as he doesn't really know about him. According to Yuni, both Tsuna and Byakuran are similar in some way, which both didn't really understand.
Weapons and Abilities
Tsuna is capable of using the Dying Will Flame (when shot with special bullets or having taken certain pills), which is a form of high pressured energy capable of having destructive powers or purifying evil auras. It initially lies within a person's body until it is awakened, helping increase a person's strength. When a person is able to control the full potential and power of the Dying Will they are able to go into (Hyper) Dying Will Mode at any time. Reborn said that any one has the potential to do this, but not many people can withstand the training phases.
- Dying Will Mode: This mode is activated when Tsuna is shot by Reborn's Dying Will Bullet or having taken a Dying Will Pill. It uses the pressure he faces during a crisis to externally remove Tsuna's body limiters. He then uses his increased strength and renewed confidence to fulfill his dying will, which is the last thought he regretted before being shot.
- Hyper Dying Will Mode: This is when one has been hit with the Criticism Shot or ingested two Dying Will Pills. Hyper Dying Will, instead of removing external limiters on the body and using pressure during a crisis, removes internal limiters; therefore, releasing the person's hidden awareness. When the internal limiters are lifted, it awakens his Hyper Intuition.
- Oath Flame: A combination of the Earth Flame and Sky Flame that forms a extremely powerful Flame. This flame has the abilities of both the Sky and Earth Flame and was created when the Earth Simon Ring and the Ring of the Sky Version X fused together.
- Sky Vongola Ring: Won after the Ring Battles with the Varia. Tsuna usually wears this Ring around his neck, but he wears it behind his right glove when he is fighting. In the future, both Future Tsuna and Present Tsuna learned how to release Sky Flames with the Harmony characterization. Tsuna is also able to open any kind of Box Weapon using the Sky Flames produced by the Sky Vongola Ring, though the power is less than those opened with the original Flame attribute. In addition, it can also not bring out the true potential of the box weapons. During his battle with Byakuran, a manifestation of Vongola Primo appeared and granted Tsuna and his Guardians the true power of the Vongola Rings. As a result, Tsuna's Flames and techniques have dramatically increased in power.
- Vongola Box Ring (Natsu): After Byakuran was defeated, the Vongola were told that they couldn't take the Vongola Boxes with them. But with Verde's help, the Vongola Boxes were turned into Rings and were brought back to the present with the Vongola.
- Ring of the Sky Version X: A newly formed ring created by combining the Sky Vongola Ring and Vongola Box Ring (Natsu).
- X-Gloves (エクスグローブ, Ekusu guroobu): Created by Reborn's pet, Leon. At first, they appear to be white, wool mittens, but when used with the Dying Will Flame, they change into a pair of black, metal-clad Gloves.
- X-Gloves, Version Vongola Ring: Though otherwise identical to the X-Gloves the Vongola Ring Version Gloves have a large crests resembling the Sky Vongola Ring on the back of each hand.
- X-Gloves, Version Vongola Gear: The new gloves now seem to be mostly red, unlike the previous gloves' black. The normal crystal blue Vongola Emblem in the middle now has a red cross on top of it reading "Vongola Famiglia," and Flame type designs cover the bases of the gloves. Also, as part of the gear, a leg bangle has been added. This bangle is similar to the Ring of the Sky Version X, as it is connected by a chain to a simple belt with an "X" as a buckle.
- Flame Resistant Clothing: These are spun from special Flame Resistant Cloth made by Leon and are capable of withstanding the Dying Will Flame to an extent.
- Contact Lenses: Created by Spanner, these Special Contacts display a targeting system, as well as a system to gauge the strength of the Flames in both X-Gloves. Using these Contacts, Tsuna is able to maximize the power of the X-Burner without propelling himself. The Contacts are apparently interfaced with his earphones.
- X-Headphones: Created by Giannini during the Future Arc, as a method of communication during the Merone Base invasion. Per Reborn's request, this headset is able to project holograms to allow Reborn to help Tsuna from a distance. Spanner later linked the headsets to the contact lenses he created to help Tsuna perfect his X-Burner. The present Spanner created upgrades for these along with upgrades for the contact lenses.
- Lancia's Boss's Ring: Lancia gave this Ring to Tsuna before the latter left with Basil for Italy. Tsuna brought it with him to the future, and found out that it was a special ring until it was detected by a Strau Mosca shortly after meeting Lal Mirch. It also protected him from Byakuran's Mini White Dragon.
- Motorbike/Airbike: In the manga, Tsuna has a Honda 250cc NSR Rothmans. In the anime, the airbikes have identical appearances aside from differences in coloration, so Tsuna's color is primarily white with some blue.
- Leone di Cieli Version Vongola (Vongola Sky Lion): Tsuna's Vongola Box Weapon, which takes the form of a young lion with a mane made of Sky Flames.
- Cambio Forma Modo Difesa (Mantello di Vongola Primo): Through Cambio Forma, Natsu changes into a long, black Cloak. The Cloak is attached to a metal plate on the X-Gloves. The Cloak's Ability is to nullify attacks using the Sky's Harmony characterization.
- Cambio Forma Modo Attaco (Mitena di Vongola Primo): Natsu combines with the X-Gloves and turns into a Gauntlet. While using this, Tsuna can concentrate all his Flames into a single attack without charging.
- Leone di Cieli Version X: This is the Vongola Gear version of Natsu, Tsuna's Vongola Box Weapon. With the upgrade, Natsu has armor on his legs and is wearing armor with the Vongola crest on his forehead. Natsu is capable of merging directly with Tsuna for the latter's Cambio Forma.
- Version Vongola Gear: Natsu fuses with Tsuna and his Vongola Gear X-Gloves and turns into flame-patterned arm thrusters. These thrusters can be used to support the XX-Burner or emit Flames powerful enough to escape the gravity of a black hole.
- Modo Attaco (Attack Mode: Vongola First's Gauntlet): Natsu fuses with Tsuna's right Vongola Gear Glove and turns into a gauntlet used by the first Vongola Boss.
- Vongola Hyper Intuition - It is described by Reborn as being "a power that could see through all."
- Minus State - Tsuna can rest his Flames and pass out. After, Tsuna can return to his Hyper Dying Will Mode without getting hit with a Criticism Shot or having to ingest two Dying Will Pills.
- Zero Point Breakthrough: Revised: Tsuna's own version of the Zero Point Breakthrough. The revised Technique allows Tsuna to not only absorb the enemy Flames, but convert the Flames into his own power.
- Zero Point Breakthrough: First Edition: The Technique used by the First Vongola and later the Ninth Vongola and Tsuna. It takes Tsuna to be in the opposite state of the Hyper Dying Will State to create ice, which is highly negative compressed energy that can seal Dying Will Flames away and can only be melted by the Dying Will Flames.
- X-Burner: A powerful blast of Dying Will Flame from the X-Gloves Version Vongola Ring usable on the ground and in the air.
- XX Burner: Tsuna's upgraded version of X Burner, used after gaining his Cambio Forma Version Vongola Gear. Soft flames fired out backwards absorb the recoil of the front facing flames.
- X-Stream: Tsuna dives down at the enemy, and rapidly begins to circle them from bottom to the top, flames lagging behind, until they are completely covered with spiraling flames.
- Hyper X-Stream: Hyper X-Stream is a more powerful version of the original X-Stream attack used by Tsuna. Tsuna flies toward his enemy and rapidly circles them from bottom to top, Flames lagging behind his feet, until his target is completely trapped in a tornado of Sky Flames.
- Big Bang Axle: Tsuna concentrates Flames in his fist while using Mitena di Vongola Primo to deliver a powerful punch which is said to rival the X-Burner in power.
- Burning Axle: After gaining the Original Vongola Rings, the Big Bang Axle gained more power, and was dubbed the Burning Axle.
- X Cannon: After gaining the new Cambio Forma Version Vongola Gear, Tsuna can shoot two powerful blasts with an X shape from the hand with the other hand on the arm.
- Gravity Manipulation: After gaining the power of the Oath Flame, Tsuna is able to utilize the power of the Earth Flame and uses its Gravity Manipulation powers.
- Flame-Enhanced Punch: Tsuna coats his arms in Sky Flames and punches the target.
- His nickname, "Tsuna", is often connected to "tuna." His bedroom door has a tuna fish with his name on it. A common shorthand of his name used among fans is "27", while his Hyper Dying Will Mode is "72" the opposite of normal Tsuna. In Japanese, 2 sounds like "Tsu" and 7 is pronounced "Nana"; hence, "Tsu-na."

- In the game, Jump Ultimate Stars, where Tsuna and Reborn are characters, when Reborn shoots Tsuna with a Dying Will Bullet, Tsuna's flame is blue instead of the original orange, which reflects the Sky Flames.
