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! 5th place of Tsugi Manga Awards, Category Webmanga - Retail: (Direct Retail From the Mangaka) ![](https://i.imgur.com/0e9KPgq.png) Official Melon Books ![](https://i.imgur.com/t9hf4kQ.png) Official Toranoana ![](https://i.imgur.com/lGJEbPa.png) Official DLSite (jp)
