Bludgeoning Angel Dokuro-chan

In a future where humanity's pursuit of eternal youth has offended the divine, a junior high student named Kusakabe Sakura is destined to invent immortality, halting the aging process for women after the age of twelve. As a consequence, an angel from the future, Dokuro-chan, is dispatched to eliminate him. However, Dokuro-chan chooses to spare Sakura's life, instead opting to keep him perpetually occupied, preventing him from ever developing the immortality technology. Her unorthodox method of protection often spirals out of control, with Dokuro-chan periodically killing Sakura with her trusty bat, Excalibolg, only to effortlessly revive him, all while maintaining a peculiar and humorous demeanor.
