|The Missing Reborn|
|Volume||Ten Years Later|
The World, 10 Years Later
Tsuna catches up to Lancia, Basil, and Reborn, asking them why they were leaving for Italy without a word, to which Basil and Lancia reply with their own reasons. Lancia then gives Tsuna his former boss's ring, and Basil presents Tsuna with Dying Will Pills. Lambo comes and, thinking the Dying Will Pills were candy, tries to eat it. However, Reborn beats him up, causing Lambo to fire his Ten Year Bazooka, but backfiring, as Reborn hit him, causing the missile to fly wild. The missile ended up hitting Reborn instead, but with no replacement from the future, much to Tsuna's shock.
Tsuna recalls the fact that it would reverse in 5 minutes, but after a day, Reborn was still missing. Tsuna runs into Gokudera and Haru, informing them that Reborn was missing, causing them all to split up and look for him. Tsuna goes into his house and asks Lambo if he could replace himself with his older self, Lambo denying that the bazooka existed. However, Tsuna finds it in his hair and tugs for it, but ends up firing it at himself instead. He travels to the future, lifting a lid off of a coffin, coming face to face with an older Gokudera.
