Kiri Komori, a student in class 2-F, begins as a hikikomori confined to her home until a teacher intervenes, prompting her transition to an unused classroom. Though now attending school, she clings to secluded spaces, often cocooned in a blanket for comfort. Her long dark hair frames a quiet, shy presence, her attire beneath the blanket shifting between outfits—sometimes hinting at undergarments—while the fabric remains her constant shield.

Warm and gentle with the teacher and a trusted classmate she supports, Kiri’s demeanor shifts when rivals vie for the teacher’s focus, sparking subtle tensions with peers. Her name mirrors her identity: in Eastern order, “Komori Kiri” echoes “komorikiri” (“one who stays home”), while reversed as “Kiri Komori,” it phonetically mirrors “hikikomori.” A specific episode reveals her birthday, though broader backstories or character arcs beyond this detail remain unexplored in existing sources.
