Katekyou Hitman Reborn!

Definition

There is no putting it lightly—Tsunayoshi Sawada is just no good. He is clumsy, talentless, and desperately in love with the school idol Kyouko Sasagawa, a girl so completely out of his league. Dubbed "Loser Tsuna" by his classmates, he seems to be the very personification of failure in the guise of a middle-schooler.
