A somewhat strange and exceedingly optimistic student who always sees everything in the single most positive light possible: the polar opposite of Nozomu, who sees only the dark side of things and is constantly in despair.

Her cheerfulness apparently conceals a traumatic past. Her father tried to hang himself all the time, as did her mom once. At one point her mother was possessed by demons. In addition, her recent actions; watching the school burn down with a satisfied grin, and the more harmless act of disguising herself as a college girl and making food for her teacher and his nephew hint at a much darker personality. Another hint is the fact that one or more of the other characters are mortally terrified of her; for example, when Kafuka teaches Meru about communication through eye contact, Meru can sense only bloodlust in her eyes. Another episode hinted that she was slitting her wrists as it is shown that her wrists were wrapped in bandages.

she was referred to as "An-chan" in a flashback, and the surname "Akagi" appears in the attendance book, leading fans to speculate that her real name is An Akagi. This would parallel Nozomu's comment in the first chapter about her personality resembling Anne of Green Gables (赤毛のアン, Akage no An).
