Chieko Kakazu, the disciplined guidance counselor at the protagonists’ school, strictly enforces regulations, often chastising students such as Kouichi Madanbashi for infractions like incorrect uniform attire. Her striking physical presence, marked by a curvaceous figure and prominent bust, becomes a calculated tool in her efforts to control scenarios or advance her goals.

Beyond routine discipline, she actively targets student dynamics, notably attempting to sabotage Kiriko Kiyuna and Shouma Ameku’s relationship by luring Shouma through seduction. This maneuver aims to curb their overt romantic displays, which attract staff complaints, showcasing her pragmatic yet unorthodox methods to uphold order—though the couple remains undeterred.

Her surname, Kakazu, blends the characters for "praise, auspicious" (嘉) and "number" (数), while her given name, Chieko, derives from "wisdom" (智), "benefit" (恵), and "child" (子).
