Pop'n Music Wiki

Akemi Koyama is one of the CS characters from Pop'n Music 7.


ハツカネズミなんだけど、そのガンバリが認められ OLになった明美さん。 最近ひそかに、ポップンミュージックというゲームに ハマって会社帰りに毎日やってるらしいよ。
Akemi-san is a mouse, but recently, she's been accepted as an office lady for her hard work. Recently and secretly, it seems that she has been addicted to playing Pop'n Music everyday, and she does so every day after work.

Akemi is a talking Japanese mouse who works as a secretary at a legal office. She writes romantic thriller books and plays Pop'n Music in her spare time.



Akemi appears to be a bisque-colored mouse with buck teeth, short, blonde hair and a fuchsia tail. She sports a simple shirt with a light blue, overalls dress. She wields a pen with fuchsia flower patterns and a light pink bird on the clicker.

Miracle 2[]

Akemi gains a new attire, which includes a light honeydew, long-sleeved blouse, and a white knee-length skirt with light pink flower prints. She is located in front of a tea cup with the same manner as her skirt, while she is sitting on a chair.


Akemi's appearance is dramatically different, unlike her first two appearances. Her hair is tinted in chocolate brown, and she wears a light-pink dentist's outfit. She carries around a mouth mirror with a sickle probe on the bottom. The 2P palette retains her original color scheme, and she also gains a blue and white dentist's outfit.
