草壁 桜

Sakura is a 13-year-old second-year junior high school student whose life changed the day the "Bludgeoning Angel" Dokuro-chan appeared. Since then his life has become one of her gory clubbings and resurrections. This has come about because some time in the future, Sakura is apparently destined to create a technology that stops girls from aging after they reach the age of twelve years. Dokuro, an angel assassin, is sent back in time to prevent this by killing him. She fails to do so because she falls in love with him. Sakura's life is still in danger because a second angel assassin has been sent back in time to ensure his elimination. 

Due to having two young heart-breakingly beautiful angels attracted to him, Sakura gains a reputation as a pedophile at school (though this is only because the male population are jealous of him). While not perverted by nature, Sakura finds himself in tricky situations with Dokuro and her sister, Zakuro. 

Sakura has a crush on his classmate and childhood friend, Shizuki Minakami, who he spends much of his time with but is too afraid to confess his feelings. Despite gradually developing feelings for Dokuro, despite the way she treats him, Sakura continues to pursue Shizuki, even going on a date with her which fails when Dokuro and Sabato intervene. He is indecisive, and he is unable to choose between Shizuki and Dokuro even towards the end of the series.
