## Description
No matter how hard he tries, Aihara Takuya is just a weakling. Not only the boys, but the girls pick on him too! His step sister, Natsumi, the president of his school's chemistry club, Mami, and even his childhood friend, Asuka, they all enjoy teasing him.

Just when he thinks his life couldn't get any worse, he spills some vials of chemicals while cleaning up his school's chemistry room, splashing some onto his body as well. He looks down to assess the mess, and finds a new pair of breasts sticking out of his chest! He grabs them in disbelief, and discovers that he's been transformed into a girl!

And so begins Takuya's hilarious erotic adventure to search for a cure. Along the way he discovers a whole new world of experiences, some welcome and others not. Will he find a way back to normal, or will he be trapped in a girl's body for the rest of his life?

## Characters
### Aihara Takuya (相原 拓也)
Aihara Takuya is a normal, unimpressive guy. Most people don't notice him because he's short, weak, and sort of a nerd; his only extracurricular interest is the chemistry club. Accidents with chemicals have caused Takuya some unique and painful problems in the past, but his next one just may change his entire life! A seemingly innocuous spill has changed Takuya into a woman this time!

Natsumi's boyfriend, [url=https://vndb.org/c17526]Seiji[/url], might also find the new Takuya interesting. With such peculiar people interested in him, Takuya's time as a female will likely (not) be as fun as he hopes it to be.

Will his confession be answered with the same kind of feelings by Takuya?
