Onii-chan wa Oshimai! / Onii-chan is Done For! / ONIMAI: Sekarang Aku Kakak Perempuanmu! / อวสานพี่ชาย กลายเป็นพี่สาว / 不當哥哥了！ / Я стал сестрой! / ONIMAI: Ab sofort Schwester!Summary
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!
