- Sakura is a 13-year-old 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 an 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 undeserved reputation as a pedophile around his school (though this is only because the male population are jealous of him having two heart-breakingly beautiful angels attracted to him). While not perverted by nature, Sakura still manages to get into tricky situations with Dokuro and her sister, Zakuro. Sakura has a crush on his classmate and childhood friend, Shizuki Minakami, whom he spends much of his time with but is too afraid to confess his feelings. Despite gradually developing feelings for Dokuro even with the way she treats him, Sakura continues to pursue after Shizuki, even going on a date with her which ultimately fails when Dokuro and Sabato intervene.
