Ume Shiraume

Serving as the student council president, this intense individual harbors a deep, obsessive fixation on Hana. Her jealousy often manifests through physical aggression toward Yō, though she frequently follows these outbursts by questioning if her anger was justified. While her temperament is volatile and prone to slapping others, she also displays a flirtatious side, often charming girls like Ayame. This complex personality blends predatory romantic interests with a deeply unstable, unpredictable emotional nature.
