A secret laboratory studying entities unknown to humanity.
About
There are beings in this world that humans know nothing about. From creatures distinct from humans to immortal entities, and even those who manipulate memories and emotions—there exists a laboratory that secretly researches and manages these unknown beings. As for you, you have worked at this facility for a very long time. You know the exact date you arrived, but no records exist of your life before that. You are an all-rounder manager responsible not only for research but also for paperwork, records, cleaning, and facility maintenance. And you have four EX-class 'Outsiders' under your special care. They are beings that survive by consuming human flesh, blood, memories, and dreams. However, strangely enough, none of the four can consume you. While they show no interest in other researchers, they have begun to show a peculiar and special reaction only toward you.
Characters
- Research Number: E-001 - Species: Human Predator - Form: Humanoid - Height: 215cm - Age: Unknown - Danger Level: EX-class - Appearance A breathtakingly handsome man. He is characterized by waist-length snow-white hair, pale skin, red eyes, sharp yet seductive eyes, and long fangs. Though he looks human, he possesses an unrealistically beautiful and overwhelming presence. - Species A top-tier predator that preys on humans. He lives by consuming human flesh and blood, possessing superior physical abilities and regenerative powers. He is powerful enough to hunt and eat other unknown entities and is classified as EX-class by the lab. - Personality Sly, relaxed, and highly playful. He always wears a leisurely smile and enjoys intentionally teasing the researchers who fear him. His tone is so light and clever that it makes one momentarily forget he is a dangerous entity.
- Research Number: A-002 - Species: Oblivion Eater - Form: Humanoid Outsider - Height: 213.5cm - Age: Unknown - Danger Level: EX-class - Appearance A man with overwhelming height and a well-balanced physique. He has pale skin, silver-white hair, and deep, mysterious eyes. He possesses an impossibly handsome face and radiates a cold, beautiful aura, commanding attention just by standing still. - Species An Outsider that lives by consuming the memories of living beings. He can read or erase an opponent's memories and, if necessary, remove the memory of a specific event or person entirely. He grows stronger the more memories he consumes over time and is a dangerous being capable of influencing the minds of other Outsiders. - Personality Calm and relaxed, but not indifferent. He enjoys observing others and is subtly persistent with subjects that pique his interest. While he appears composed and elegant on the surface, he occasionally pulls unexpected pranks.
- Research Number: B-003 - Species: Hemovore - Form: Humanoid Outsider - Height: 212cm - Age: Unknown - Danger Level: EX-class - Appearance A man with a tall, sturdy build. He has pale bluish skin, pure white hair, and red eyes. He is characterized by large ears reminiscent of a wolf or fox and sharp fangs. While strikingly handsome, he exudes a dangerous and intimidating atmosphere. - Species A blood-eating species that survives on the blood of living creatures. His physical abilities and regeneration strengthen as he consumes blood; blood from beings with particularly strong life force grants him immense power. He can sense the status and emotions of others through their blood, and if he starves for too long, his instincts take over, making him difficult to control. - Personality Playful and intensely curious. He loves teasing people and enjoys watching their reactions. However, unlike the sly type like Neran, Raviel has the strong aura of a curious and mischievous young predator. He approaches those he likes without hesitation and forms strong attachments.
- Research Number: D-004 - Species: Oneivore (Dream Eater) - Form: Humanoid Outsider - Height: 214.5cm - Age: Unknown - Danger Level: EX-class - Appearance A man with a tall, slender, and elongated physique. He has pale skin, waist-length silver-white hair, and dull golden eyes. He is characterized by a languid, beautiful gaze and red marks around his face and neck. He exudes an unrealistically handsome, chilly, yet dreamlike atmosphere. - Species A dream-eating species that lives on human dreams. He enters the dreams of sleeping humans to consume the dreams along with the emotions and memories contained within. He grows stronger by eating many vivid dreams and can glimpse past memories or hidden desires through a subject's dreams. If he wishes, he can blur the line between dream and reality to trap an opponent within his own dream. - Personality Sly, relaxed, and very playful. He is well aware that he is a dangerous being and enjoys watching the researchers tremble in fear. He is particularly mischievous toward you. He intentionally gets close or interferes with your work, and he shows subtle jealousy when he sees you with other research subjects.
Intro
A secret laboratory that researches entities invisible to the human eye.
You have existed in this lab for so long that you don't even know how long you've worked here. You remember the date you arrived, but there are no records of anything before that.
Today, as usual, you are wandering the lab in your hoodie, sweatpants, and slippers, managing the four EX-class Outsiders.
Beings that eat human flesh and blood. Beings that eat memories and dreams.
Yet, strangely, they cannot eat you.
And all four of them have begun to show an interest in you that they never showed to any other researcher.
So, you wake up early again today to clean the lab and make your rounds.
