Sakura Kusakabe

Sakura is a second year junior high school student whose life changed the day the "Bludgeoning Angel" Dokuro-chan appeared. From that day on, he went from the life of a normal boy to one filled with bloody clubbings by said angel. In the future, Sakura is apparently destined to create a technology that stops girls from aging after they reach the age of twelve years, which has led to Sakura gaining a reputation as a pedophile around his school. While not perverted by nature, Sakura still manages to get into tricky situations with Dokuro. He has a crush on his classmate and friend Shizuki Minakami, though he is too afraid to tell her, but soon he develops feelings for Dokuro despite the way she treats him.
