Kokuma Jutsu is a canon character who attends Akademi High School.
Kokuma has short dark blue hair with bangs that fall in the middle of her forehead. Her eyes are light purple with dark circles beneath them. She always has a shadow on the top half of her face. She wears the default uniform unless customized by the player, along with a moon choker if the Occult Club is active and bandages over her right eye.
Kokuma has the Coward persona. If Ayano tries to take a photo of her face without being in the Photography Club, she will hide behind her hands. If she witnesses murder, she will begin to beg Ayano to spare her in exchange for her silence.
- Her hair was inspired by Rei Ayanami from Neon Genesis Evangelion.
- Her name basically translates to "black magic" in English.
- Her student profile states that she claims the bandages on her face are there due to an attack from a wild animal. Some of the students believe that she is actually regularly beaten by a family member and was blinded in her right eye during a domestic dispute.
