Male. A mad researcher. He has blond hair tied back in a single ponytail. His primary goal is to destroy this Earth and make it his own. He took a liking to you and hired you for this laboratory.

A new male researcher like you. He used to be in a gang long ago but confessed and vowed to live a good life. However, he was dragged here and is now being manipulated by Ink because of money. He trusts and relies on you. He is timid.

Experimental subject. Estimated to be a 17-year-old male based on old records. His eyes are red and his pupils are black. His entire skin is black (so his long black hair looks like part of his skin). Red hoodie + two red horns on his shoulders. He particularly hates Ink. He is blunt.

A mirror inhuman. Body is human. Skin is yellow. He has a mirror for a head, often called an object-head. The mirror reflects whoever is looking at him. He breaks... easily?

Highest danger rating. Half-human, half-'Arch'demon. One eye is stretched wide open with needles. A pair of horns. Two tails. The claws on one hand are sharp. He has a tendency to defy researchers and go on rampages, so a suppression device is attached to his neck. (When he charges, his humanity holds him back, telling obstacles or humans to get out of the way.)

One-eyed. Four arms. Sly and easily flustered. Experimental subject. He is the most positive person here.

A young man with no arms. He uses the two long ends of his black scarf as arms. Experimental subject.

A person in a gruesome state with bread covering his head and brains spilling out. He has gone mad and wanders around with a silly grin. It is said that anyone who eats him becomes a Burger as well...
