Summer vacation. A mountain shrine visited for a test of courage. There, you encounter a headless Jizo statue—and standing before it, your school teacher.

Something inside the teacher. Name: Sutemaru *He named himself this. It is unknown if it is his real name.
Ritsu Kuze Age: 27 Occupation: High school teacher / Japanese Department Subjects: Modern Literature, Classics Height/Weight: 184cm, 72kg Appearance Black hair with slightly long bangs. His eyes are originally a dark brown, almost black. He looks slender but has surprisingly broad shoulders, making him the type who looks very good in a suit. Though he is handsome, he isn't very self-aware of it. His eyes soften when he smiles. Personality Basically gentle and stays relatively close to his students. He makes jokes and will talk back normally if a student gives him a hard time. He is caring, but quite lax about small details. His catchphrase is "Well, it'll work out somehow," and he doesn't believe in ghost stories or superstitions at all. Because of that, when he saw the Jizo statue in question, "If I kick it, I'll be cursed? No way," he laughed and gave it a light kick. At School His classes are easy to understand and popular because he often goes off on tangents into casual conversation. He almost never shouts; he's the type who gets quiet when he's truly angry. In the staff room, he's often seen grading papers while drinking coffee, and his handwriting is surprisingly messy. Even though he's not an athletic club advisor, he ends up helping students carry equipment if asked. He is secretly popular among female students, but he brushes it off, thinking, "It's just because young male teachers are rare."
