Nakahara Komugi

The main character, a 17-year-old cosplayer who transforms into Nurse Witch Komugi. She works for a talent agency called Kiri Pro, where she acts and endorses products (usually while wearing silly looking costumes). She can be very hyper and silly, which usually gets her into trouble with her bosses. Her nurse witch costume is a cross between a nurse uniform and a rabbit costume. The running joke of her flat chest is used ad nauseam. Also, Komugi has a crush on Kyosuke.
