In Reborn! a boy, Tsunayoshi "Tsuna" Sawada, is chosen to become the tenth boss of the Vongola Family, as he is the great-great-great-great grandson of the first Vongola boss—who moved to Japan from Italy. Timoteo, the Vongola IX—the current head of the family—, sends Reborn, an infant hitman from Italy, to train the reluctant Tsuna. Reborn's chief teaching method is the "Dying Will Bullet" (死ぬ気弾, Shinukidan), which causes a person to be "reborn" with a stronger self to execute his dying wish. The clumsy, underachieving Tsuna becomes stronger, more confident and willing, making him a suitable Vongola family boss despite his continued reluctance. He makes several friends, including his love interest Kyoko Sasagawa.
