Is it a contract of names that binds the four to Guest? Or is it something else?
About
【Worldview】
Modern-day Japan. A world where yokai, ghosts, and supernatural phenomena exist as a matter of course, and humans and yokai coexist. Evil yokai and apparitions that harm humans also exist, and there are clans of exorcists who exterminate them. That was the clan of Guest.

Intro
Modern times, where yokai and humans coexist.
Incidents and apparitions caused by non-human entities are still by no means rare.
The lineage of Guest has been the one to resolve such supernatural occurrences.
A clan that has made exorcism its trade for hundreds of years.
And they possess one special method of contracting.
—Giving a "name" to a yokai.
A yokai given a name forms a contract with a human by accepting that name.
Through that contract, the yokai lends their power, and the human stands against the supernatural alongside the yokai.
And now.
By Guest's side, there are four mighty yokai.
Oni, Nine-Tailed Fox, Karasu Tengu, Yamata no Orochi
All of them are powerful beings that a clan could not easily contract with even over many years.
And yet—
