Lambo vs. Rauji Ooyama
Tsuna and Gokudera are trapped within a crystal cage and can only watch Lambo and Rauji. Just then, Reborn arrives and comments on Rauji's plan to lure Lambo. When Tsuna tells Lambo that he will help him, Rauji informs him that the ceiling is being help by the strength of the wall and that breaking the wall will cause the ceiling to collapse on Lambo. He also informs them that the way they came through have already been sealed and that they can only sit and watch. Lambo is completely unaware of the situation and tries to get Rauji to play as his servant. A serious Rauji grabs him and begins to throw him around, saying that he will no longer be Lambo's slave. Lambo thinks that the fight is just another game since he thinks that Rauji is timid since they haven't seen each other for a long time. Rauji refuses to play, saying that Enma is his only boss and that after he kill Lambo, he will kill the others one by one. Lambo still does not understand the situation and begins to prepare his toys for them to play with.
As Lambo teases Rauji with his candy, Rauji approaches him and destroys his toys. An enraged Lambo is determined to have Rauji play with him, his determination manages to awaken the Vongola Stone and upgrade it to the Vongola Gear which changes into the Thunder Helm Version X. However, he decides to take it off since it's too tight for his head, much to Tsuna and Gokudera's dismay. Rauji tricks Lambo into playing, sumo wrestling with him with the first one to leave the platform being the loser. Lambo happily accepts and Rauji immediately attacks him causing him to fall off the platform. Rauji thinks that Lambo is dead and thinks that even if he is alive, he will be imprisoned by the Vindice. However, Lambo managed to use his Ten Year Bazooka and changed into his future self, who managed to cling on the edge of the platform and gets ready to fight against Rauji...
