A Passionate High School Tale as a Cute, Soft Little Girl

After countless cycles of reincarnation and battles, she goes from being a timid, useless high school senior boy to a little girl.

And not just any little girl: she's the neighbor's younger sister, the one he used to bully as a child before reincarnating.

This world worships martial strength. In the post-apocalyptic base cities, the law of the jungle is the only law. Schools are breeding grounds for the ruthless: fighting is allowed, and teachers won't interfere as long as nobody dies. Everyone wants the bottle of evolutionary serum that can transform them and make them superior to others.

But this body of hers is small and frail, utterly powerless, and even running a couple of steps leaves her panting.

Though she has a wealth of skills and combat experience, the battles raging across this city are bound to be grueling. But she is no longer timid, and she no longer fears a challenge!

This is the story of a soft and adorable little girl who uses her fists to fight for redemption and passion in a post-apocalyptic school ruled by the law of the jungle.

The cuter she looks, the harder she hits.
