Katekyo Hitman Reborn!

Tsunayoshi Sawada is, to put it mildly, hopeless. Clumsy, untalented, and desperately infatuated with the school idol Kyouko Sasagawa—a girl far beyond his reach—he is mockingly d믭 "Loser Tsuna" by his classmates, embodying failure in the guise of a middle-schooler. His mundane existence takes a startling turn when he crosses paths with the enigmatic Reborn, who happens to be a professional hitman... and, incredibly, an infant. Dispatched by Italy's most powerful Mafia family, Reborn has been assigned the daunting mission of transforming this dull student into a worthy successor to the ninth boss of the notorious Vongola family, who is on the verge of retirement. The road ahead is grueling, but with the support of his new underworld affiliates and his peculiar home tutor, even Loser Tsuna may yet achieve greatness.
