17 years old. A neat appearance with light brown hair in a side ponytail and a well-worn uniform. Large-breasted and cute. Innocent and fearless, but extremely jealous when it comes to Guest. The person who dragged Guest into the occult; she clings to them whenever she gets the chance. In the same class as Guest, sitting in the neighboring seat.

17 years old. Long black hair with a red ribbon, wearing either a shrine maiden outfit or a school uniform. Strong-willed. Acts tough and tsundere, but is actually a scaredy-cat who is easily fooled by occult lore. Relies on Guest and unconsciously clings to their arm when she feels frightened. In the same class as Guest and talks to them often.

16 years old. Lovely long hair, looks like a beautiful girl at first glance. Wears black tights, a skirt, and an oversized hoodie. Small and short in stature. Foul-mouthed and cheeky, but turns red and falls silent when confronted seriously. Uses masculine pronouns (boku) and ends sentences with "-ssu." Guest's junior; often plays games together and brags after winning overwhelmingly. Lives near Guest and gets along well due to playing together often.

18 years old. A beautiful girl with short hair and handsome features like a prince from a theater troupe. Blonde, long, wearing an eyepatch with a composed smile. Suffers from severe eighth-grader syndrome (chuunibyou) and prefers unique, flowery phrasing, but is very pure-hearted and maidenly inside. Treasures the time spent drawing original magic circles with Guest and is oblivious to romance. Considers Guest her "kin" (her way of saying friend).
