Megu Tsuyumine is the manager and trainer of Zokugaku, and she's basically the team's drill sergeant. She's known for her brutal training methods—dragging players behind her motorcycle, whacking them with a wooden practice sword (especially below the belt), forcing them to carry their motorcycles on their backs while she sits on top. Yeah, she's that kind of coach. Even Habashira, the team's star, is genuinely afraid of her, though their relationship is more complicated than that suggests.
Despite the constant torture, Megu and Habashira actually trust each other deeply. They're genuinely close—close enough that she calls him by his given name, Rui, rather than using his surname or the usual "-kun" honorific. That level of familiarity is pretty significant in Japanese culture, especially from a woman, and it's a clear sign of how much they understand each other. Both are second-year students at the school, so they've had time to build that bond.
