Tsugumi serves as the Library Club president—a position Tamamo picked her for. She and Tamamo are basically inseparable; they're each other's best friend.
She's honestly kind of spacey most of the time, but she's better at running the club than you'd expect. That said, she leans heavily on Tamamo to keep things on track. When Tamamo's not around to consult, Tsugumi turns to Kyoutarou for advice about club stuff instead.
