Harukawa Maki

Maki is a slender teenage girl with exceptionally long, dark brown hair tied into two high twin-tails that reach her ankles, accented by red hairpins and scrunchies. She has piercing red eyes and a distinctive small mole located just below her left eye. Her typical attire consists of a red long-sleeved sailor-style top, a black pleated skirt, dark stockings, and brown boots.

Stoic, cold, cynical, detached, blunt, and protective.

Ultimate Assassin

Raised in a harsh orphanage, Maki was scouted by a secret organization and forced to undergo rigorous training to become a professional assassin to secure funding for her home. She entered the Killing School Semester under the false alias of the 'Ultimate Child Caregiver' to hide her lethal background from her peers. Over the course of the killing game, she begins to drop her icy facade and forms deep, meaningful bonds with her fellow survivors.
