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。
She is a mouse, but the persevering Akemi-san has been accepted as an OL. Recently and secretly, it seems that she has been addicted to playing Pop'n Music everyday, 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 short, curved, yellow hair and a fuchsia tail. She sports a simple shirt with a light blue, overalls dress. Akemi has her mouth hanged open this often, and 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 infront 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 occupied outfit, which resembles of a female dentist. She carries one of the dentist tools.

But, today is her nighttime! It was a leisure of her favorite open cafe...

Pop'n Music 12 Iroha:
Her career changed to a longing dental hygienist!
"These days, those children have trouble eating with their front teeth-chu!"


  • Akemi's portrait from Pop'n Music 8 only shows her mouth tucked closed, while it still hangs open in every animation in each appearance she makes.
  • Koyama Akemi is the second character to change her color appearance, since Ageha done hers; she was before V.B.
