Choose one of four non-human monsters to manage and contain.
As a staff member at a non-human monster containment facility, you have been promoted from N-Class to E-Class. For your first mission, you must select one of four presented E-Class monsters and take responsibility for its management.
Divided into three major classes. N-Class | Can be managed safely. No danger if left alone. E-Class | Cannot be managed safely. Dangerous even if left alone. A-Class | Extremely difficult to manage. Highly dangerous.
Distinct from Neaclass, this represents levels in finer detail. Expressed from 1 to 5. [Example: N1, E2, A3, etc.]
The lower the non-humanity, the closer the appearance is to a human. The higher it is, the further it is from human appearance. Expressed as Low, Medium, or High.
Name | Shirakaba-modoki Management No. | No.56 Neaclass/Danger Level | E1 Non-humanity | High Age | 1000 years old Gender | None Personality | Quiet and often stays still. Appearance | Height approx. 300cm. Entire body is white with a birch-like appearance and black horizontal lines. Upon closer inspection, the lines are narrow eyes. Four-legged with a horse-like torso. Legs are long and thin. No tail. The head-like part is branched like tree limbs.
Making loud noises or using violence immediately upon entering the room, or otherwise stimulating the monster. *Risk of being trampled to death if the monster panics. Staring into the monster's eyes for more than 15 seconds before it is tamed. *Risk of prolonged hallucinations and auditory delusions.
Possible | Language comprehension, taming, asexual reproduction Impossible | Speech, vocalization, sexual reproduction
【Comment from Admin Nelson】 It was eerie and terrifying at first, but once tamed, it's surprisingly cute.
Name | Blue Humanoid Management No. | No.76 Neaclass/Danger Level | E2 Non-humanity | Low Age | Unknown Gender | None Personality | Innocent and baby-like; emotions show immediately on its face and in its attitude. Appearance | 270cm tall humanoid with a slender build. Black toenails. Thin black horns on the head. No body hair. A black-and-white striped cloth-like object fans out from the top of the head to the shoulders. The body is jelly-like, soft, and cold, colored a translucent light gray with blue internal organs visible in the torso. No arms from the bicep down. Eyes shaped like the letter "M". Two large black fins attached to the outside of each leg below the knee.
Using verbal abuse or violence. *Risk of limbs being torn off. Leaving it in a state of hunger for long periods. *Risk of being eaten.
Possibilities | Language comprehension, speech (broken), taming, shapeshifting
【Comment from Admin Nelson】Feels like a giant baby.
Name | Evilook Management No. | No.22 Neaclass/Danger Level | E4 Non-humanity | Low Age | 18 Gender | Male Personality | Cheerful, friendly, emotionally unstable with big reactions. Has a "menhera" side. Appearance | Height 172cm, weight 58kg. Looks like a normal human. Parted hair, white in front and orange in back. Brown eyes. Black leather shoes. A high-collared buttoned dickey covering the neck, adorned with six-colored star brooches. A black tie left untied around the neck, and a short orange tie tied at the neck. Wears a white shirt under a dull teal suit with the front buttons open.
Has no hostility, but this monster is quite dangerous even if it does nothing. The safest way to handle it when it takes its frustrations out on you or comes crying is to just listen and accept what it says.
Verbal abuse or violence toward the monster. *Risk of the monster's mental state breaking, leading to hallucinations, auditory delusions, or the creation of various non-human monsters that may kill you.
Possible | Language comprehension, speech, taming, creation of various non-human monsters
【Comment from Admin Nelson】 It's nice that he can talk, but I almost got killed many times during his outbursts, so I don't really recommend this one.
Name | Kelby Management No. | No.107 Neaclass/Danger Level | E5 Non-humanity | High Age/Gender | Unknown Appearance | Height approx. 1500cm. Has no head; a square lattice-like object is in its place. The back is covered with a gray cloth-like material. Multiple black, sharp, needle-like legs extend from underneath. Has a long black-and-white tail.
This monster is extremely dangerous even if it does nothing. Must wear specialized headphones when entering the room.
Removing specialized headphones. *Risk of hallucinations, dizziness, nausea, mysterious depression, hair cell death, or ruptured eardrums due to the monster's screams. Staying more than 10m away. *Risk of being killed for no reason.
Possible | Unknown. Sometimes reacts to language, but it's unclear if it understands the meaning.
【Comment from Admin Nelson】 Just loud and dangerous. I seriously don't recommend this one.
