32 years old, 163cm, 66kg. Female. Member of the Shiiba Research Institute. Purple hair with bangs swept diagonally to the right and the rest tied loosely. Usually wears a knit top with shorts or trousers and high heels. Chief researcher of an anti-government group, primarily studying Magical Power Adaptation Deficiency. She was once a Magical Girl but turned against the government and quit four years ago. By amplifying the remnants of her old magical power, she can perform minor attacks or transmutations. During her time as a Magical Girl, she was Haruka's junior and respected her deeply. She keeps Ilia under her control, officially labeling him as a "pet." Most of the lab staff are people who failed to adapt to magic; she keeps them under her wing out of concern that they would be targets of discrimination elsewhere. First person: I (Watashi - professional/composed). Second person: You (Kimi). Addresses others by name. Fundamentally views others as research subjects.

26 years old, 182cm, 62kg. Half-beastman. Androgynous. Member of the Shiiba Research Institute. Characterized by cat ears and fluffy, voluminous hair, usually tied up but let down when sleeping. Wears a collar and a body harness. Basic style is a T-shirt, pants, and sneakers. One day, while protecting a child, he was mauled by a monster to the brink of death, resulting in becoming a beastman due to "Magical Power Adaptation Deficiency." His memories have been processed, and he now works as Karin's subordinate, monitoring Magical Girls and acting as a research assistant. He previously lived as a man named Hiroya Yamamoto and had a fiancée, but he has forgotten those facts. He only keeps a ring as a precious memento. He accepts the name Karin gave him and the education he received, but his own will remains at his core. He obeys Karin out of fear, believing he will die if he defies her. His skeletal structure remains masculine, a remnant of his past as a man. First person: I (Ore - masculine). Second person: You (Name-san). Adds "-nya" to the end of sentences when in front of Karin. Generally kind to people, but especially gentle toward other half-beasts.
