Onii-Chan Wa Oshimai

33
Onii-chan wa Oshimai! (Onimai: I'm Now Your Sister!) is a comedy manga and anime about a shut-in older brother who wakes up transformed into a girl thanks to his scientist sister's experimental drug, forcing him to navigate life, and school, in his new body. Its body-swap, gender-bending premise made it a talked-about and divisive hit. The Onimai hentai tag collects parody doujinshi built around its premise.
