Tsunayoshi Sawada isn't good, to put it mildly. He's clumsy, untalented, and hopelessly in love with Kyouko Sasagawa, the school's idol, a girl far out of his league. His classmates have dubbed him "Loser Tsuna," and he appears to be the personification of failure disguised as a middle-schooler.

Tsuna's mundane existence is turned upside down when he meets the mysterious Reborn, who happens to be a hitman... and, more unexpectedly, a baby! Reborn is sent from Italy's most powerful Mafia family with the difficult task of grooming a drab middle schooler to succeed the legendary Vongola family's ninth leader, who is about to retire. The dull boy faces a difficult journey ahead of him, but with the help of his friends, he can get through it.Loser Tsuna faces a difficult road ahead, but with the support of his new criminal associates and his odd home instructor, he may be able to reach greatness.
