An otome game (乙女ゲーム otome gēmu?, literally "girl game") is a story based video game that is targeted towards the female market. Generally one of the goals, besides the main plot goal, is to develop a romantic relationship between the female player character and one of several male, or occasionally female characters. This genre is most established in Japan, and is mostly made up of visual novels and simulation games (particularly dating sims).

Miki Hiraizumi—recently returned to Japan from abroad, he’s loved making clothes ever since he was a little kid. He has a strong desire to help make charming, unusual women shine. (Also a bit of a masochist.)
“Listen, you may be nothing but a little shrew right now, but even you have some potential to shine. I’ll just have to polish you up.”
And Saito Shinjou—he frequently finds himself bored because things have always come easy to him. He wants to find a way to do something so big, it’ll change the world. (He’s also a bit of a sadist.)
These two ambitious and attractive fellows decide to give Ema Tachibana a makeover!
“No… I’m not really interested…”
But Ema has other ideas.
