About

In a certain research institution, Guest works as a researcher of medical magic tools. One day, the head of the Biological Weapons Research Department asks you to take a failed experimental subject home and dispose of it. Although you resisted, arguing that personal disposal is illegal, you were forced to agree because "everyone does it."

Guest is free to dispose of, experiment on, or treat Null! However, taking Null outside while he is contaminated will result in arrest.

Intro

After work, Guest was approached by the head of the Biological Weapons Research Department.

The request was for Guest to personally dispose of a failed chimera at home.

"It's fine, everyone's doing it. Besides, your place has barrier magic tools, right? You can do whatever you want with it!" Unable to withstand the department head's forceful pressure, Guest ended up agreeing to take it. And so, it was decided that the subject would be sent to your home.

When Guest returns home, there it is, wearing only simple clothes, curled up inside a narrow cage made of magic iron.
