Loner (1/1/16 – 1/15/16)
|Appears||Week 1 (Debug)|
She has short, dark, navy blue hair with a purple-grey bandage covering her right eye. Her bangs are shaggy and fall in the middle of her forehead. Her visible eye is purple, but the other eye's color is unknown. The top half of her face is slightly shadowed. She wears a black choker with a crescent moon on it. If the Occult Club disbands, she will not wear the choker anymore.
Among the personas currently implemented in the game, she is a Coward. If Kokuma sees a corpse, she will run away from the school and call the police. If she witnesses a murder, she will start begging the player to spare her life in exchange for her silence. She cannot participate in physical fights against murderers. If she witnesses Yandere-chan commit murder, she will think that Yandere-chan is possessed by a demon, according to Oka Ruto. Because she is a Coward, if the player has their camera aimed at her face, she will hide it.
At 7:05 AM, Kokuma enters the school grounds. She walks to her locker at 7:10 AM and changes from her outdoor shoes to her indoor shoes. At 7:15 AM, she walks to the Occult Club on the first floor to chat with other club members then they will go to research the seven mysteries of the school.
At 8:00 AM, she walks into Classroom 1-2 and sits at her desk. She starts her morning classes at 8:30 AM, and leaves to go to the outside of the Occult Club to eat her lunch at 1:00 PM.
Kokuma walks back to class again at 1:30 PM and participates in cleaning time between 3:30 PM and 4:00 PM. Afterwards, she heads to the Occult Club and stays there until the end of the day. If the player joins in club activities, she will unsuccessfully try to summon a demon with the other members from 5:30 PM to 6:00 PM.
If the Occult Club is inactive, she will socialize with the other former members outside of the club during periods when she would normally attend it (7:15 AM, 1:00 PM, and 3:30 PM).
- She was implemented in the January 1st, 2016 Build.
- Her hairstyle is a reference to Rei Ayanami from the anime Neon Genesis Evangelion.
- A blue version of her hairstyle can be found when pressing H. It is the ninth hairstyle available.
- Her name is a play on words, coming from the Japanese word kokumajutsu (黒魔術) meaning "black magic".
- As stated in her Student Profile, she claims that the bandages on her face are the result of being attacked by a wild animal shortly before the school year began. However, there are rumors that the true reason she wears bandages is because she is regularly beaten by a family member, and was blinded in one eye during a domestic dispute.
