Kiku

Endou Kiku, a delinquent lone wolf, is pissed off with the world and everyone in it. Until he meets Senji and Sanji, who were just like him until they met each other. This one volume story follows Kiku as he finds out what it means to have friends and not be alone in the world, while also kicking ass and taking names in the meantime. This is the original Takahashi Hiroshi delinquent manga, predating his more famous works Crows, QP and Worst.
