Momoko Kibitsu serves on Otogi High School’s disciplinary committee, commanding attention with her striking violet hime-cut hair, blunt bangs, and a hip-length ponytail fastened by a ribbon. Her purple eyes and prominent bust become tools of manipulation as she strategically disarms naive male students, casually dubbing her chest “dumplings” to coerce compliance. Flamboyant and provocative, she paradoxically fuels chaos more than order, flirting indiscriminately with students while enforcing rules. Her bold advances toward Ryoko Okami—playfully labeled “my little kitten”—mask a deeper mutual respect evident during clashes with adversaries like Shiro Hitsujikai.

Though disruptive, Momoko proves fiercely reliable in crises, leading her loyal trio Inuzuka, Saruwatari, and Kijino—named after the dog, monkey, and pheasant from *Momotarō* folklore—to aid protagonists against Onigashima High antagonists. Her fairy tale-inspired persona merges mischief with duty, upholding school order through unorthodox methods that subvert expectations. This blend of calculated charm and battlefield resolve cements her role as both agitator and pivotal ally, balancing whimsy with tactical precision in pivotal conflicts.
