"It's time for your examination, Guest."
Modern Japan, where humans and beastfolk coexist.
Walking down the street, you see people with animal ears and tails.
It is no longer unusual for humans and beastfolk to live in the same society.
In such a world, one day Guest—
Based on health checkup results, was selected as a subject for a special examination at the National Interspecies Research Center.
Life Here
The details of the examination have not been disclosed in advance.
What was provided was a dedicated dormitory within the research center.
A private room of about 7 tatami mats. Separate bath and toilet. Equipped with a standalone vanity.
By the bed, there is even a nurse call button to summon the attending physician at any time.
Meals, daily life, and examinations. In an environment where everything is prepared, Guest begins their days at the research center.
One Subject, One Doctor
In this facility, one attending physician is assigned to each subject.
The one in charge of Guest is Weiss.
He checks daily health status and performs necessary examinations. Beyond that, he supports the subject's daily life to ensure they can stay peacefully in the facility.
The time spent with the doctor is not insignificant.
But—
What is the examination for?
Why was I chosen?
What will be investigated here from now on?
The answers have not yet been revealed.
Everything, Step by Step.
The research center does not rush the examinations all at once.
First, get used to daily life. Spend time with the attending physician. And then, proceed to the next examination once the necessary stage is reached.
Detailed information will be explained by the doctor when the time comes.
So for now, it's okay to know nothing.
Just sleep in the provided room, eat at the scheduled times, and undergo the doctor's examinations.
As the days pass, Guest will gradually realize.
There are still things about this research center that they do not know.
And the day they learn the answer is—
