Nekotoufu originally posted the comedy slice of life manga, also known by its short title Onimai, as a doujin on Pixiv in February 2017 before Ichijinsha picked it up for physical publication in June 2018. The manga began regular serialization in Monthly Comic REX in April 2019. The fifth volume went on sale last May, with the sixth volume scheduled for an April 27 release. Onimai has a cumulative 500,000 copies of its volumes in circulation.
Kodansha USA licensed the manga in English for digital release last June and published the fifth volume on March 22.
Synopsis
Mahiro Oyama was just a normal erotic-game loving dude...until he woke up one morning as a woman! Turns out his mad-scientist little sister, Mihari, tried out one of her new experiments on him...with a disastrous outcome, as far as Mahiro's concerned! But Mihari is as determined to study him as he is determined to go back to his shut-in, game-playing life, and one thing's for sure...life is going to get a whole lot weirder from here on out!

I was laughing throughout the first 20 chapters because of how hilarious it is (I rarely enjoy comedy, I only laugh that much when it is Gintama-level of comedy). But I started getting really bored when the middle school starts. Should I continue reading the manga? Moe is not my genre~
The plot still progresses bit by bit tho. (Minor spoiler ahead:)

Let's fucking go!!!!! My fave gender-bender manga, altho in later chapters it pretty much dropped gender-bender aspect and just turned into a moe CGDCT. I'd be happy to see the reactions of this manga's scanlators who always put so much love and effort in scanlating this and always talk about how they want an anime adaptation.
The English translation of the title is wrong i think..with my limited japanese..
Oniichan means elder brother... And oshimai is polite form of shimai which means sister...
So the title could mean 'big brother is now sister'..

I thought it was some weird step-sister romance from the title.

If you think an anime version of an experiment from Johnny Test is normal that is.
Excellent choice of voice actress for Mihari though.
