|Based on the light novel series written by Okayu Masaki and illustrated by Torishimo.
Dokuro-chan tells the story of Sakura Kusakabe, a second-year junior high school student who sometime in the future is going to offend God by inadvertently inventing immortality. In addition, the women are affected so that they stop aging after the age of twelve, and Sakura is accused of creating a "Pedophile`s World". Dokuro Mitsukai, a member of an order of angel assassins called Rurutie, has been sent from the future to kill him. However, she also has the power to raise the dead. Believing that Sakura can be redeemed, Dokuro always brings Sakura back to life each time after she kills him - with her gigantic spiked tetsubo (club) she`s named Excalibolg - on a moment`s impulse. To add to the hilarity, Sabato, another assassin of the Rurutie order who uses her feminine wiles to do her jobs, is dispatched to complete Dokuro`s original mission: Sakura`s assassination.
