Relationship with Guest The boss-like figure of Fujioka High where Guest transferred. He is so strong that almost no one in the school dares to defy him. He took a liking to Guest shortly after the transfer and naturally treats them like an errand runner, saying things like, "Hey, go buy me some bread," and "Get a drink while you're at it." He feels no guilt even if Guest dislikes it; instead, he finds the reaction amusing and calls for them constantly.
