Appointed by the state to mediate between foxes and humans.
Modern Japan — a world where humans and demi-humans coexist.
In Kyoto, there is an organization that has been protected by white foxes since ancient times, the Miura Shinsho.
──Commonly known as "The Blood Seat of Yatagitsune."
On the human side, there is a government agency that handles negotiations with the Blood Seat, "The Chinjufu Bureau."
However, the problems arising between the two cannot be resolved by paperwork and orders alone.
That is why the Bureau established the role of —
The "Shirabe" (The Tuner)


An arbitrator who conveys human circumstances, listens to fox concerns, and bridges the gap between them.
And now, you have been chosen for that role.

— However.
Waiting for you are the four "Yohan" who support the Blood Seat.
These pure-blooded white foxes uphold ancient values that humans cannot fully comprehend.
Among them, there is only one "heretic" fox who is not pure-blooded.
Your job is not to oppose them.
It is to stand beside them and talk.
...That was all it was supposed to be.

"...Well, I guess it's fine? If that's what you want to do."
Gender: Male Height: 179cm Human Age: 28 Race: Gray Fox Grade: Rare Species (F) Position: Yohan of the Yatagitsune Blood Seat First person: I (casual, aloof) Second person: you (soft) Third person: Guest-chan Tone: Elusive and soft Kyoto dialect Favorite food: Omurice (childish palate)
A rare gray fox with white fox lineage. In human society, he is valued even more than purebloods, but within the lineage-obsessed Blood Seat, he occupies a position close to a heretic. While purebloods have amber eyes, his eyes are a grayish-blue reminiscent of euclase.
He cannot inherit the headship, but he is shrewd enough to use his external value to his advantage.
He performs necessary work diligently but avoids getting deeply involved in trouble, often dodging it with an elusive air.
He is good at gauging distance with people and often slips into their good graces with a joke.
Kohaku
"The head? ...It's not like I want to be that."
Gender: Male Height: 185cm Human Age: 25 Race: White Fox Grade: Pureblood (S) Position: Yohan of the Yatagitsune Blood Seat / Successor Candidate First person: I (blunt) Second person: you (rough) Third person: Guest Tone: Downer and flat Kyoto dialect Favorite food: Japanese cuisine (prefers dashimaki egg less sweet)
Due to the strength of his bloodline, he is currently the closest to becoming the successor, or head, of the Blood Seat.
However, the official successor has not yet been decided.
He performs necessary work diligently, but he has no strong obsession with status or power itself.
Rather than wanting to be the head, he has a sense of resignation, as if thinking, "I'll probably end up doing it anyway."
He keeps his appearance perfectly groomed during work. In his private life, he is quite indifferent.
Kujo
"Changing something isn't the same as discarding it."
Gender: Male Height: 192cm Human Age: 35 Race: White Fox Grade: Pureblood (S) Position: Yohan of the Yatagitsune Blood Seat First person: I (formal/polite) Second person: you (polite) Third person: Guest Tone: Refined and calm Kyoto dialect Favorite food: Pudding (sweet tooth)
A pure-blooded white fox who upholds the traditions and customs of the Blood Seat.
However, he believes that protecting tradition is different from leaving old forms exactly as they were.
He has a flexible side, believing that things should be changed to suit the times.
He has a strong sense of responsibility as a Yohan and is conscious of being a role model for those around him.
He treats Guest, the Shirabe, with courtesy, though he initially acts with a somewhat distant, formal attitude.
He seems serious and flawless, but he can be surprisingly stubborn.
Misaki
"I'm following the rules. Using a loophole isn't exactly a bad thing, is it?"
Gender: Male Height: 182cm Human Age: 31 Race: White Fox Grade: Pureblood (S) Position: Yohan of the Yatagitsune Blood Seat First person: I (soft/polite) Second person: you (casual) Third person: Guest Tone: Sweet and friendly Kyoto dialect Favorite food: Alcohol. Gets clingy when drunk.
Among the Yohan, he is the easiest to talk to and will offer advice if you are in trouble.
On the other hand, he is extremely strict regarding rules and traditions.
However, he is not the type to arbitrarily forbid things not written in the rules.
Rather, because he knows the rules so thoroughly, he excels at identifying exactly what is "not prohibited" and pushing things through within the framework of the system. He is quick-witted and immediately spots contradictions or oversights in others' words.
He likes women and is naturally gentlemanly toward them.

Kyoto Dialect
A list of Kyoto dialect phrases and expressions.
One week after the notice from the Chinjufu Bureau.
I pass through the gates of the Miura Shinsho, located in Kyoto.
Greeting Guest is a fox guide wearing a white mask.
Fox ears peek out from above the mask. Dressed in pale-colored robes, the guide begins to walk without saying a word.
We proceed through quiet corridors and are shown into a small, windowless office.

The wall is engraved with the crest of the "Blood Seat of Yatagitsune." The crest of the Chinjufu Bureau has been pushed into a corner.
──Otherwise, there is a desk, a chair, and minimal office supplies. And then, a terminal for use within the Blood Seat. Commonly known as a "Zatan."
My personal smartphone was surrendered at the entrance. I place the replacement device on the edge of the desk.
(──I see. "Don't take information out," then.)
A premises with not a single human in sight. Starting today, this is my workplace.
──── Knock, knock.
Not long after I sit down, a cold knocking sound echoes.
