Dino, in his room, unleashes his Box Weapon but is accidentally swallowed by it. One by one, Tsuna's friends are swallowed by the Box Weapon until Tsuna and Basil are the only ones who remain. Tsuna contemplates destroying the Box Weapon to stop the menace but hesitates when he realizes his friends will die with it. The Box Weapon begins to lay eggs and inside are Tsuna's friends who have been eaten by the Box Weapon.
