Kaede Igarashi attends Ōsai Academy, progressing from freshman to upperclassman while presiding over the disciplinary committee with unwavering dedication. Her strict enforcement of rules, driven by a rigid moral code, defines her reputation. Long, light brown hair flows into twin braids down her back, paired with dark brown eyes and a stature a head shorter than Takatoshi Tsuda. Aria Shichijō’s irreverent comparison of her braids to anal beads once provoked a temporary hairstyle trade, hinting at unexpected adaptability beneath her sternness.

Her disciplined demeanor masks severe androphobia—a paralyzing fear of men rooted in an unspecified comedic incident. Proximity or touch from males triggers stuttering, trembling, or fainting, complicating her duties. Yet around trusted individuals, her sharp edges soften. A pivotal clash occurs after the student council’s beach trip: she confronts them over compromising photos, challenging Shino Amakusa’s leadership despite visibly crumbling in Takatoshi’s presence.

Persistent effort gradually tempers her phobia; by the second season, she endures Takatoshi’s nearness if contact is avoided. This hard-won resilience mirrors her dual resolve to uphold order and confront personal limits. She occasionally oversees the chorus club, though her involvement remains undetailed. Moments like the playful hairstyle exchange with Aria reveal flickers of flexibility, balancing her ironclad principles with quiet growth as she navigates academy life.
