Sibling relationships are always wacky, but ONIMAI takes it to a new level. Mihari, a mad scientist, drugs her brother so that he wakes up as a girl.
Miraculously, it works. It works too well, in my opinion, and now the poor guy has to figure out his life anew.
Well, you can’t really argue with anime logic, so what you can do is enjoy the bizarre life of Mahiro as he falls into an existential crisis.
The odd comedy anime, ONIMAI: I’m Now Your Sister!, is on its way to receiving an anime adaptation.
If you want a detailed walk-through of the series, check out the latest teaser that contains a voiced portrayal of the manga panels.
Accompany Mahiro as he wakes up without a significant part of his manhood (all of it, actually.) Although he is confused at first, he quickly realizes that this is because of an illegal experiment his sister performed on him.
Now he can’t even play his favorite erotic games (eroge) because of being spooked by his sister. Thus begins a tug-of-war between the two siblings. So far, Mahiro seems to be losing extravagantly.
The video also reveals the voice actors of the two protagonists:
| Character | Cast | Other Works |
| Mahiro Oyama | Marika Kōno | Nemu Emmott (Overlord) |
| Mihari Oyama | Kaori Ishihara | Tiese (Sword Art Online) |
The newly released visual shows Mahiro with a shy expression. The boy started off as an eroge-addicted shut-in but changed to a timid girl overnight. You’ve got to admit that Mihari has freakish science skills.
Studio Bind is animating ONIMAI: I’m Now Your Sister! and has just revealed its main staff members:
| Position | Staff | Other Works |
| Director | Shingo Fujii | Fullmetal Alchemist: Brotherhood (Key Animation) |
| Script Writer | Michiko Yokote | Tsurune |
| Character Design | Ryo Imamura | Mushoku Tensei (Key Animation) |
By now, you must have already guessed that ONIMAI is going to be a perfect comedy where logical things will rarely ever happen. Will Mihari’s experiment lead her to greatness or jail? Moreover, will Mahiro ever return to his normal self?
