ONIMAI: I'm Now Your Sister!

Ongoing

お兄ちゃんはおしまい!

Mahiro Oyama is a shut-in who spends his days playing erotic games at home. One morning, he wakes up to discover that his body has changed: he is now a girl. The culprit is his younger sister Mihari, a brilliant scientist who used him as a test subject for one of her experiments.

While Mahiro wants nothing more than to return to his old life and lock himself away again, Mihari is determined to study the effects of her experiment. Forced to adapt to his new body and to a world that now treats him differently, Mahiro must learn to live as a girl.

As Mihari pushes him to go outside, attend school, and make friends, Mahiro struggles to hold on to his identity while navigating increasingly awkward and unfamiliar situations.
