Neon

Neon is the captain of Uruha Oto (Sound) and one of the two Jyushinshuu female members, including herself and Mikoto. In strength, she is the 8th strongest next to Noroi, Kai, Raiha, Joker, Rasen, and Meguri Kyōza in raw power.

Neon is a slender, but curvaceous and attractive woman. She has multi colored hair which is mainly black, but with two red streaks in it. She is also fairly busty. Her outfit is fairly revealing, consisting of one piece outfit closed at her waist by a belt and opening again under it, falling down to her ankles. A musical note is adorned at the bottom, signifying her affiliation to the sound element. The crystal for her madōgu Fukyo Waon was placed on her right breast before it shattered.

In the anime, her multi-colored hair becomes dark red as her two streaks are orange. She retains her outfit in the manga but has a single blue pauldron armor at the right side of her outfit.
