You are Takuya Aihara, an average junior college student with one character flaw: you're a bit of a weakling. No matter how hard you try, it seems that all the girls around you are constantly pushing you around: your teasing step-sister Natsumi, the genius president of your chemistry club Mami, but especially Asuka, your beautiful childhood friend. No matter how hard you try, you just can't assert yourself.
One fateful day, while cleaning some shelves in the chemistry room, you spill a mysterious chemical on yourself. The next thing you know, you've been transformed into a girl! And so begins this hilarious erotic adventure in which poor Takuya gets some very interesting lessons in anatomy and sex education!
As a woman, Takuya discovers a new world of experiences, some welcome and others not. Can Takuya find a way back to normal, while avoiding the many temptations that come with his new female body? Can he find a way to express his feelings for Asuka, without hurting another who loves him?
