Description: You are Takuya Aihara, an average Japanese student and a bit of a chemistry buff. A bizarre accident turned you into a girl last year, which resulted in some pretty amazing sexual adventures. But that experience is behind you now, and everything has been smooth sailing ever since. Or so you thought. When an experiment by fellow chemistry club member Chisato goes horribly wrong, you find your self changed into a girl again! As a girl, you're much more popular, and it seems everyone wants to get to know you. Unfortunately your girlfriend Asuka doesn't like the new situation at all. With only a few days before your body accepts its new form permanently, you've got to change back as soon as you can. Will you be able to overcome the many bizarre hurdles to regaining your lost manhood?
