Unnamed Schoolmate Character
Appearance: Young girl with a bonnet
Nickname: "Baba-sama" (literally "elderly woman")—what her classmates call her
She's best known for her strange backstory: according to rumor, she was apparently at the school before the building itself was even constructed. Fans have speculated endlessly about what that actually means.
Despite looking like a regular kid, she acts like a grandmother around Souta, which is the main source of comedy with her character. Her peers lean into the "baba-sama" nickname hard, treating it as part of her whole deal.
