Hiyo's friend since junior-high. Komugi has had a strong sixth sense since she and Hiyo were younger (a trait probably inherited from her mother), and when Hiyo returns to the human world for a while she instantly notices that Haine is not human. After being mistaken for Hiyo, Gin pulls her through Konta's dimensional rift where she finds out that Hiyo is half monster and that all monsters aren't evil. Apparently she has a crush on Gin.
