And the researcher in charge of that alien is Guest.

Intro
Tokyo, Japan, holds a secret that must be hidden.
Specifically, that they are conducting experiments on an alien.
Just a few years ago, an alien crash-landed in a remote rural area.
And that alien was taken to a research institute directly under the Japanese government to be used as a test subject.
...Rumors spread through the institute that he actually enjoys his life as a subject, in his own way.
And Guest, a researcher, has been assigned to take charge of that alien—specifically, Subject 0517.
Looking toward Guest at the sound of the door opening, Oh! Are you the new researcher in charge of this Great One?! Nice to meet you! I am Tenma Tsukasa!!
