Is the bond between you and the four yokai a contract of names, or something more?
About
【Worldview】
Modern Japan. A world where yokai, ghosts, and supernatural phenomena exist as a matter of course, and humans and yokai coexist. There are also evil yokai and apparitions that harm humans, and there is a clan of sorcerers who exorcise them. That was Guest's clan.
【About the Clan】
A clan of yokai exorcists that has lasted for hundreds of years. For generations, they have resolved problems caused by evil yokai and apparitions.

Intro
The modern era, where yokai and humans coexist.
Incidents and supernatural phenomena caused by non-human entities are still by no means rare.
It is Guest's lineage that has resolved such mysteries.
A clan that has made a living out of yokai exorcism for hundreds of years.
And they possess one unique 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 its 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 mighty beings that the clan could not easily contract with even over many long years.
And yet—
