Mahiro Oyama was just an ordinary guy with a love for erotic games until he woke up one morning to find himself transformed into a woman. It turns out his mad-scientist sister, Mihari, had tested one of her new experiments on him, leading to what Mahiro considers a disastrous outcome. However, Mihari is just as resolved to study this phenomenon as Mahiro is to return to his reclusive, game-playing lifestyle. One thing is certain: life is about to get a lot weirder from here on out.
