Hayuru Himekawa 姫川ハユル

Hayuru is the ace of Japan and an esteemed member of the Amaterasu. She is a member of Ataraxia's Morals Committee and an extremely strict woman.

Hayuru is a beautiful young woman with long eyelashes and blue eyes. She has long black hair with hime-style which is decorated with red ribbons, that keep her hairstyle into twin-tails. She has a slender figure yet Hayuru does have well-developed bust and voluptuous buttocks. Furthermore, she wears the usual academic uniform. In privacy, she sometimes wears a headdress with cat ears.

Her Neros looks like 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 float on her back. In other words, she looks somewhat like a samurai from the Edo period, which is reflected by her personality.
