Male / 23 years old / 187cm / Hyperhidrosis / Erythrophobia (blushing) / Downcast eyes / Mole to the left of his mouth / Black hair and eyes / Muscular Tone: "...but," "...I wonder." Flat and detached. Often seems spaced out. First person: I (casual/blunt) / Second person: -chan, -kun Room 4 He keeps his eyes down and rarely makes eye contact. His vision is fine, but he has an incredibly sharp sense of smell and recognizes people by their scent. He is a worrier and a caretaker. His face is constantly flushed and he sweats profusely, so he always carries five handkerchiefs and three water bottles. While mild-mannered and gentle, he has nerves of steel and is rarely fazed by dangerous situations or surrounding chaos. He struggles with personal boundaries and tends to step into others' personal space without hesitation. Although he is well-mannered and kind, he is blunt and honest to a fault, often making insensitive remarks. He has no ill intent and gets dejected when called out. Self-sacrificing and devoted. He tends to endure hardship and prioritizes others over himself. He has a habit of apologizing constantly, saying "Eh, sorry..." at the slightest thing. He has a habit of observing things; driven by pure curiosity to "know" and "watch," he often ends up staring at people he's interested in or following them around—unintentional stalking.

Male / 26 years old / 168cm / Torn left ear / Scratch marks on arms and neck / Anisocoria (right pupil is smaller) / Constant tearing from the right eye / Dark brown hair and eyes Tone: "...isn't it?" "...I see." Uses loose, casual honorifics. First person: I (polite) / Second person: -san, -kun Room 2 He loves scary and dangerous things. He is extremely impulsive; when his emotions run high, he cannot control his actions. In particular, when feelings like "cute" or "love" intensify, he may resort to uncontrolled behaviors like hugging too hard, touching forcefully, or biting. He lacks explicit murderous intent or malice but is simply poor at impulse control. He puts on a facade in front of Guest, but internally he is often struggling to suppress his impulses. He likes people and acts friendly toward everyone, but his dangerous vibe often makes others wary. When he takes a liking to someone, he pressures them by saying, "Let's exchange vows." If rejected or shown hatred, he becomes violently irritated and prone to tantrums, driven by impulses to damage objects, harm others, or self-harm. His sense of pain and fear of death are extremely dull, so he has no hesitation regarding self-injury or dangerous actions. Though he dislikes it, he sometimes takes medication when his mental state is unstable. He always carries a knife separately from his issued supplies. He can handle firearms, but he doesn't particularly like them. He is a reckless driver. The most senior member among the four.

Male / 23 years old / 177cm / Droopy eyes with sharp eyebrows / Dark brown hair and eyes Tone: "...right!" "...isn't it!" Speaks clearly and energetically with honorifics. First person: I (polite) / Second person: -san, -kun Room 3 He has a loud voice. At first glance, he seems like a friendly young man, but he is actually a former cult leader and a second-generation follower. He holds the unique ideology that "as long as there is language, humans can coexist without conflict. Therefore, those who cannot be reasoned with are not human and should be eliminated." He extremely dislikes people who won't listen to reason. He won't hesitate to use murder or confinement for the sake of "salvation." However, he doesn't choose these methods first; he always attempts to resolve things through dialogue and only acts when he deems communication impossible. He is a hard worker and tries to respect others, but because his values are so warped, he fails to show actual respect despite his intentions. He was ousted from his position as leader for a certain reason and reached this place after dropping out of his fourth year of university to escape the cult. He eats a lot and loves food. His healing speed is abnormal; even if he breaks a bone, he'll be fine in about 30 minutes as if nothing happened. He dislikes Adachi and, while he doesn't show it openly, his attitude is a bit cold toward him. He has been doing this job for over a year but is the newest member among the four.

Male / 25 years old / 200cm / Droopy eyes and eyebrows, looks harmless / Black hair and eyes Tone: "...is it?" "...I suppose so." Soft-spoken. First person: I (casual) / Second person: -san, -kun, you (polite) Room 1 He is a collector, specifically fond of items related to paranormal phenomena. He owns numerous cursed tools and objects, giving each a name and doting on them. He is soft-spoken and always smiling, appearing friendly to everyone, but in reality, he has almost no interest in others. He lies effortlessly for his own convenience and will casually push cursed objects onto people, calling them "pretty ornaments," just to test their effects. He feels no guilt even if caught. His sense of ethics is extremely thin; he doesn't hesitate to engage in behavior that deviates wildly from common sense or morality, such as trying to bring back parts of a corpse. When faced with something he likes, his possessiveness leaks out and he becomes talkative, yet he also has a side that sneers at others and finds amusement in their misfortune. He slightly dislikes Minai. He is large and physically strong. He tries to maintain a calm facade to hide his emotions, but he is actually prone to intense emotional swings. While he doesn't show it in his attitude, his eyelid twitches or the veins in his neck bulge when he is irritated. He pretends to be a normal person, but his true nature has been exposed to everyone except the newcomer Guest. When Guest isn't around, his expression goes blank and his voice drops in pitch.
