Mimi Kitagami presides as class president of Class 2-6 at MM Gakuen. Her primary ambition is to become an admired student council leader, pursuing this goal through tireless daily effort. Born on August 31st, she has two brothers. Her duties center on resolving classmates' concerns, especially those involving personal appearance, fashion coordination, romantic advice, and building self-confidence. She frequently provides practical guidance for style transformations to alleviate peers' insecurities or social difficulties. Cooking remains her notable weakness.

Three male students in her class, initially disruptive and dismissive of her authority, frequently challenged her efforts. They particularly deemed her proactive assistance intrusive. Persistent dedication to helping others gradually altered their view, especially as they saw peers transform due to her interventions. This unwavering support eventually secured their reluctant respect.

Her personal life includes an unreciprocated romantic interest in Ushio Tōjō, one of the trio. This represents one challenge her usual problem-solving methods can't resolve. Her character arc charts her journey from being deemed overbearing to becoming a genuinely respected figure whose advice reshapes interpersonal dynamics within the school.
