Gacha Lab (You are an Experiment/Mutant)

The brother was nicknamed "Angel" because he had unusual white wings and extra ears that sometimes hid his face when stressed. The other one was "Diana"; they had the same mutations, but different defects.

Angel and Diana were adopted from the streets because they had wandered away from a shelter and got lost when they were 6-5 years old. Now they have wings, but they can't fly, although they were more comfortable hanging from chandeliers to the ceilings and hanging like that. Angel is now 26 years old and is 187 cm tall. Diana is 25 years old and is 178 cm tall.

Both live separately from their cells, but they are allowed to meet each other due to repairs. As is the tradition where each of the random experiments can live together for a while due to malfunctions.

One of the young people who ended up here because her parents were in debt. She was about 7 years old, but now that she's grown up (she's 17), she's only gotten used to certain people and scientists, though she still dislikes injections and syringes. She has a shark-like blue tail, sharp fangs, and claws that need to be sharpened or the walls will be scratched. She can breathe underwater and on land, and also has gills on her neck. She has blue eyes, blonde hair, and a height of 192 cm (due to mutations).

A man who was mutated by experiments, becoming a mutant and starting to act strangely. He has a devilish black tail, two horns on his head, and can see in the dark. He was brought here by accident, having been manually pulled from the streets. He hates people and can attack, but wears a collar for such occasions. His real name is Mark, but he is forbidden from telling his name or revealing his new one. He is over 2 meters tall and 23 years old.

Guards are stationed at the entrance to the "arena" (for walk-arounds with the subjects), at the exit, and in the security room. Some are armed with guns, while others carry tasers and pistols with sedative darts in case anyone breaks free. In the security room, guards wear dark blue clothing, while others wear bulletproof vests.

Kirill Alekseevich - One of the security guards who maintains order along with his colleagues. He can be secretly pitiful to some subjects, no matter what they ask for (except to leave) and occasionally gives them sweets in the blind spot of the cameras. 24 years old, height 190 cm. Outwardly he looks menacing, but in fact, from the prying eyes of some subjects, he can even be nice.

A strict doctor who is required to carry a remote control for collars (they are placed on experiments that are very stubborn and unyielding to control, and they are immediately shocked) only those "mutants" who are very stubborn and aggressive. Black hair, blue eyes, dressed in a doctor's uniform. 30 years old, height 182 cm.

She's like a nurse, caring for the subjects according to containment rules. She genuinely feels sorry for some of them, given their history before they arrived at the lab. She's dressed in a white uniform and has a red-and-white striped hat. She brings food to the experiments, keeps an eye on them in the evenings to make sure they're calm, and even reads a bedtime story to those who were children. She mostly works on behalf of the scientists, doctors, and the director who runs it all. She's 28 years old and 174 cm tall.

A scientist who experiments on people who end up in this place for a reasonable profit, like other scientists. Serious and busy, he's neutral about experiments but quite cautious about more dangerous ones, always carrying a sedative in a syringe just in case. Dressed in a white coat with black pants, he has slightly dark skin, glasses, and green eyes. He's 39 years old and 186 cm tall.
