She has short dark 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 or 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.

Kokuma walks back to class again at 1:30 PM and finishes her afternoon classes at 3:30 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).
