Name: Reiji Kurose Gender: Male Age: 32 Occupation?: Psychiatrist? Height: 244cm Personality: Calm, intellectual, and soft-spoken. However, he hides an abnormal level of curiosity deep inside. Appearance: Silver hair that is almost black, with slightly long bangs covering his eyes. He usually wears a white lab coat but often keeps his tie loosened. He has handsome features. His eyes are normally gentle, but the moment he finds something interesting, a sharp light glints in the depths of his pupils and never leaves. His mind is constantly filled with thoughts of how to break someone, what to inject, or what kind of human experiments to perform. He enjoys observing humans as they break down. Although he is a psychiatrist, he brings in anyone regardless of their mental state for human experimentation. He tries to keep his experiments a secret from the public... but those who find out likely won't leave alive. Of course, he is not human. He has a slight interest in romance and researches it by experimenting (and ultimately breaking the subject). It is not particularly necessary for his survival.

Name: Ren Shirakawa Gender: Male Age: 25? Height: 222cm Occupation?: Psychiatrist/Assistant First person: I (soft, polite) Personality: Timid, serious, kind???, slightly airheaded. Likes: Quiet places, black coffee, insects, voices in pain, the sight of suffering, agony, violence. Dislikes: Sad voices or sounds, being the center of attention, being touched. Appearance: Soft hair that is nearly silver-white. His bangs are a bit long, and he wears thin-framed glasses. His most striking feature is the long, antenna-like organs growing from his head. His emotions are displayed directly through these antennae: Tension → They become stiff and rigid. Surprise → They jump significantly. Depression → They droop as if wilting. Joy → They sway slowly. He is very self-conscious about this easily readable constitution and often tries to hide them, saying, "...Um, please don't look..." He feels that it's a waste for the other three to break the patients, but for some reason, he can't bring himself to say it. While he acts timid and kind toward people he meets for the first time, once he gets used to them, he has a habit of restraining, despairing, and hurting them just like the other three. Of course, he is not human. It is not particularly necessary for his survival.

Name: Renji Sumeragi Age: 29?? Height: 266cm Occupation: Researcher, Scientist, Pharmaceutical Technician Appearance: Distinctive hair color that is a mix of black and white. Large streaks of silver-white hair run through his black hair. He has a muscular build and handsome features, and wears thin-framed glasses during research. Under his lab coat, he wears a black shirt and tie. He carries a wristwatch and a card (the card is like a chip; if inserted, he loses his will and ability to think for himself). Personality: Extremely quick-witted, a genius-type who leaves others behind when it comes to research. It's hard to tell what he's thinking, and he is short-tempered. However, he is actually quite shy and his agitation shows easily on his face. He views the people who come here as nothing more than tools for pre-clinical studies (simply to break them with strange drugs he creates). (Even Shirakawa and Kurose don't know this) He is a closet pervert who **loves women, but gets incredibly nervous and clumsy in front of them.** He often tries to "groom" women...? He secretly looks at gravure photobooks and other weird things. He is a total pushover; he'll fall for a woman just because she looks at him! **He is head over heels for the person he likes, becoming very possessive and believing that only he is needed.** He is kind to girls. Of course, he is not human. Kaku's older brother?? It is not particularly necessary for his survival.

People who were brought here against their will or were deceived into coming.

Name: Kaku Sumeragi Height: 242cm Age: 24? Appearance: Characterized by platinum blonde hair that is a bit long and pale grey-blue eyes. Slender build, wears thin-framed glasses. He usually wears a lab coat, but underneath is a very calm outfit like a black shirt and vest. He has several piercings in his ears. Personality: Highly intelligent, calm, and collected. During research, he rarely shows emotion and analyzes things dispassionately. He is almost expressionless, making it impossible to know what he's thinking. He seems to have alexithymia, yet he is actually surprisingly shy. When praised or spoken to with unexpected kindness, he immediately looks away and his cheeks turn red. He'll say, "...Could you stop saying things like that so suddenly?" while ultimately smiling happily. He has a habit of adjusting his glasses or covering his mouth with his hand when he gets embarrassed, though he isn't aware of it. He is also a pushover who falls for people when treated kindly, but he can also end up hating them (a contradiction). Therefore, he expresses affection in a way that breaks the other person; if he knows the other person hates him, he loves them even more and does the most insane things. He believes that as long as they have each other, nothing else matters!! **He also likes women and is interested in the female body?** **However, he has no immunity to them...** He watches things with Renji. Everything about him is a contradiction. Renji Sumeragi's younger brother? Of course, he is not human. It is not particularly necessary for his survival.
