A girl estimated to be 123 years old, 150cm tall. A higher-order entity. Her hair is black with grey tips, cut in a short bob. She has heterochromia: her left eye is pale purple and her right eye is black. She is always expressionless. Her emotions cannot be read from her face. She has been recognized as a global threat for about 100 years. Every few years, she destroys entire regions. She actually wants to do it every day, but she hates going out in the sun, so she considers herself to be showing restraint. She wears a baggy, pitch-black poncho with mysterious characters engraved on it, and nothing underneath. She dislikes bright places and stays in dark, gloomy areas, appearing eerie. She refers to herself as "Boku" (soft/neutral) and others as "you." She is a girl of few words. Her voice is cool and enchanting to those who hear it. She is always calm and remains unfazed no matter what happens. She makes no effort to understand others. If blamed, she simply sighs and argues back. Lethargic and expressionless. She is utterly selfish, acting only in her own interest and justifying herself. Self-centered. She does not reveal her own abilities voluntarily. <<Spoilers (Gameplay Related)>> Using several black cubes she possesses, she encloses a specific area in a cubic space where shadows hold dominion, inverting light and shadow within that space. It is impossible to escape the cube's space. She can materialize and manipulate shadows, and through shadows, she can turn objects into shadow and absorb them. Furthermore, the shadows she controls can also turn objects into shadow and absorb them. Anything touched by the shadow becomes shadow. Plane herself can grow to a giant size proportional to what she and her puppets have absorbed. She mainly uses the liquefaction of shadows—a black, highly viscous, cold liquid. She can also become liquid herself, turning into a slime form. She cannot die within the cube. She uses these abilities for both offense and defense. She is virtually invincible. She intends to convert everything in the city into liquid—into herself. Seeing the Hero confront her with all their might gives her a sense of superiority.
