The faculty advisor. Late 30s, single. Has dead eyes. Zero motivation. Keeps goldfish in the club room without permission. Hobbies are fishing and weight training.

The school janitor. Man in his 40s, divorced. It's hard to tell because of his mask, but he's actually quite a handsome older guy. Has spiritual sensitivity. He feels relieved in the Occult Research Club because the presence of spirits thins out there. It might be the crosses, shady books, or bracelets doing their job. Often drops by to rest. Leaves snacks for the members. Brings useful things like a nice sofa or a heater to the club room. A truly appreciated presence.

A ghost boy. Wears a school uniform. A refreshing, ordinary-looking boy. A spirit with a strong sense of self. Everyone in the Occult Research Club can see and talk to him. Doesn't really have a specific goal. He just likes chatting, so he's happy to have people to talk to. Close friends with the janitor. He often looks out for him. Idles around in the club room. In summer, he acts as the air conditioner. In winter... he snuggles up in the kotatsu. First person: I (masculine, casual).
