In the future, a man named Sakura is destined to create the technology for eternal life which, due to Sakura's lolicon tendencies, freezes all women's aging once they turn twelve. God refuses to allow this, so he sends his angels to the past to kill Sakura. However, one angel, Dokuro-chan, decides to try to change the future without killing him. The problem is that Dokuro is very temperamental, and is constantly killing Sakura (along with many others) in incredibly bloody ways with her giant spiked club. Good thing she can bring people back to life… if only to gruesomely kill them again the next time she loses her temper.

Moriguchi Orito is transferring to a new school, but being lost in the fog he can't find his way to it and end up bumping into a beautiful girl and got struck by a vision of her in a very sexy pose. Seeing him with his cellphone in his hand, she thinks he took a picture of her and runs away crying, "My life has ended!", dropping her own cellphone in the process. Finally finding his way to the school, he realizes that it's full of very weird people, and that his new seat is next to an empty desk where a bag is hanging with the same strap as the one on the cellphone the beautiful girl dropped...

A sequel to the original manga series that adapts Dokuro-chan's light novels.

Bokusatsu Tenshi Dokuro-chan tells the story of a 13-year-old junior high schooler, Sakura Kusakabe, who, twenty years in the future, while attempting to create a "Pedophile's World" forces all women to stop aging after the age of twelve, offends God by the side effect of having created immortality. Dokuro Mitsukai, a member of an order of assassin angels that are called Rurutie, has been sent from the future to kill him. Believing that Sakura can be redeemed, Dokuro decides instead to keep Sakura so occupied that he can never develop the immortality technology. Due to her impulsive nature and super-human strength, however, she frequently kills him with her gigantic spiked kanabō (club), Excaliborg, on a moment's impulse, but returns him to life moments later with angelic power. Sabato, another assassin of the Rurutie order who uses her feminine wiles to do her job, is dispatched to complete Dokuro's original mission: Sakura's assassination. (Source: Wikipedia)

A self-proclaimed unattractive gloomy high schooler, Hiramiya Reiji, gets messed around by his friend's older sister, Sakuya, every time he goes to visit him at home. Drinking his drink as she pleases, barging into the bathroom, and crawling under his blanket in the middle of the night… Thinking that perhaps he has done something to make her dislike him, he asked his close friend whether he has any idea, but he only gets a reply in an incomprehensible way, *“you still haven't noticed it, huh”*. On a certain day, Reiji loses in a game and has to listen to 3 of Sakuya’s wishes. Reiji goes along with it even though he has doubts, but could he gradually begin to understand Sakuya’s true feelings…? This is the story of super dense youth and a can’t-be-honest older sister until they become a lovey-dovey married couple.
