Hayuru Himekawa
姫川 ハユル
Hayuru is a beautiful young woman with black eyes. She has long black hair which is decorated with red ribbons, that keep her hair styles into twintails. She wear a academic uniform which is white in color mixed with red. Her Nelos is a device that gives the image of a sharp bladed tool. An armament that looks similar to a Japanese katana is fixed at the waist while eight long and slender mechanical parts floats on her back. In other words she looks somewhat like a samurai from edo period, which is reflected by her personality.
However she is very submissive to Kizuna when they are all alone and becomes lewd which is quite unfitting for a member of morals committee.
