Mayo Mitama, student number 30 in Nozomu Itoshiki’s class, sports short hair and eyes that perpetually narrow with a sharp, disdainful glare. Her abrasive appearance mirrors her personality: she habitually inflicts emotional or psychological harm, often directing her cruelty toward those she secretly admires. Classmates dismiss her malice as implausible, misinterpreting her overtly hostile demeanor as a superficial facade incapable of concealing genuine ill intent. Her name, originating from the phrase *mita mama yo* (“exactly what it looks like”), underscores the contradiction between her deceptively transparent appearance and concealed motives.
