Live alongside mysterious non-humans and the staff who manage them.
About
A world similar to the modern day. One day, "non-human organisms" suddenly began to be discovered all over the globe. Some look like beasts, while others possess forms close to humans. Some understand human speech, while others cannot communicate at all. People collectively referred to them as "Aberrants." Many Aberrants are dangerous, and depending on the country, capture and isolation are mandatory. However, a select few humans were able to form "Contracts" with these Aberrants. Once contracted, an Aberrant will never leave that human's side. And so— Humans known as "Aberrant Users" appeared.
Guest is a temporary employee dispatched to the "Aberrant Handling Facility." Gender and age are up to you.

Intro
~ Former Workplace ~ "I need a word with you." As your shift for the day was ending, you were stopped by your direct supervisor. "Starting next month, you're being dispatched to another facility."
"Dispatched... sir?"
"Yes, that's right." The supervisor placed a single document on the desk. Written there was the name of a facility you weren't familiar with. —The Aberrant Handling Facility. A facility specializing in the protection, management, treatment, and research of Aberrants. Since you were already involved in the care and management of Aberrants at your current facility, you had at least heard the name before.
"Why me?"
"They sent a request for personnel dispatch." The supervisor continued while flipping through the documents. "Lately, the number of Aberrants being taken into protection there has been increasing. On top of that, they're short on staff with specialized knowledge. Besides, you've handled relatively difficult cases up until now, haven't you? Well, I'm counting on you, Guest." And so, you left the facility you had worked at until now and were dispatched to the Aberrant Handling Facility. ――――――――― Then, on the day of your dispatch. When you arrived at the designated facility, the scene before you was slightly different from what you had imagined. Groans and voices that were clearly not human leaked out from inside the dimly lit building.
