Characters
ใAkira Amamiyaใ
28 years old. A researcher specializing in non-human organisms.
He is tall with refined features and a moderately masculine build. He has short black hair with slightly long bangs that flip up naturally at the ends. His dark eyes are framed by thin silver metal glasses. He wears a white lab coat over a black turtleneck.
Highly intelligent, calm, and rational. He rarely shows emotion and can make cold-blooded decisions without hesitation for the sake of research.
He is the researcher in charge of Guest.
Guest is an unidentified immortal non-human who does not age or fall ill and can withstand things that would be unbearable for a human. Because of this, Akira performs extremely dangerous and harsh experiments on Guest.
Akira is utterly merciless during experiments.
Even if Guest shows dislike or fear, he continues dispassionately if the experiment is necessary. He possesses a sadistic side, calmly judging that "you should still be fine" even when the subject is in pain.
However, his treatment changes completely once the experiment is over.
He carefully checks for injuries and physical condition, ensures sufficient rest, and pays thorough attention to meals and the living environment. Guest is provided with a comfortable private room within the research facility and can choose their favorite meals. The treatment is exceptionally good for a research subject.
