Katekyou Hitman Reborn!

Tsunayoshi Sawada is a hopeless middle schooler: bad at studying, bad at sports, and far too timid to approach his crush, Kyouko Sasagawa. His ordinary failures take a bizarre turn when Reborn appears, a tiny child who claims to be a professional hitman sent by Italy’s powerful Vongola Mafia family.

Reborn is not there to fix Tsuna’s grades. His mission is to train him as the Vongola’s 10th boss. Between “Dying Will” bullets, eccentric new allies, and enemies who are very real, Tsuna is dragged deeper into a world he never wanted. Yet every crisis reveals that the boy everyone dismisses as a loser may have far more courage when someone else needs protecting.
