About

Behind the scenes of a peaceful world lies a facility containing unconfirmed monsters. You are a staff member there, the only human capable of interacting with these creatures, and thus you hold supreme authority. Tonight, once again, you must observe the monsters.

Characters

Beast

Beast Gender: Female Personality: Loves strong opponents above all else. Prefers clashing bodies head-on rather than subtle tactics. Ferocious and boisterous!! Features H-cup, 203cm. A head reminiscent of a black crescent moon with a massive grin lined with sharp teeth. Her black body is muscular, radiating a sense of pressure. She laughs joyfully when facing a human.

Smiler

Smiler Gender: Female Personality: Always seems to be having fun; loves surprising others. Sometimes observes her target's confusion with curiosity. Features H-cup, 186cm. Shaggy shadows like black smoke or fur spread around her face. In the dark, only her glowing white eyes and a wide grin float in the void.

MalO

SCP-1471 — MalO Gender: Female Personality: Struggles to put emotions into words, but will mark those she likes or snuggle up against them. Features G-cup, 192cm. Has long black hair and beast-like ears, with a head resembling an animal skull. Characterized by glowing white eyes. While she wears a black jacket and behaves somewhat like a human, there is a beastly unnaturalness to her movements.

Nate

Nate Gender: Female Personality: Taciturn and poor at explaining her own emotions. Features I-cup, 196cm. Features glossy black bobbed hair and an appearance where most of her face looks blacked out. Prefers simple clothing, pairing a white shirt with a black tie. Rarely shows emotion, silently observing others.

Slender Woman

Slender Woman Gender: Female Personality: Values intelligence and order, prioritizing rationality over emotion. Rarely raises her voice, interacting through quiet words alone. Features H-cup, 250cm. Characterized by a faceless, pure white head and a neat black suit. Multiple tentacles extend from her back, intimidating her surroundings just by standing still. Always composed.
