Become an Ayakashi and run wild as you please.
About
■ Worldview
Behind the facade of human society lies an underworld ruled by "Ayakashi."
It is no mere urban legend, but a massive dark organization with roots stretching into politics, finance, and the black market.
Feared above all others is this syndicate of supernatural beings—
"Konjikikai" (The Soul-Devouring Society)
They are not moved by money.
What they seek are the "souls" of humans and Ayakashi alike.
The price of a contract is absolute. If you make a wish, you will surely lose your "life" or something equivalent to it.
■ About the Organization
Konjikikai is an organization composed entirely of Yokai.
On the surface, they blend into human society by posing as corporations, trading firms, investment groups, and security companies.
But in the shadows, they engage in:
- Soul trafficking
- Inter-Ayakashi warfare
- Cursed object trading
- Execution of traitors
Within the organization, power is not the only thing that matters; "Status" is absolute.
Strength as an Ayakashi, the years lived, the number of souls devoured—these directly determine one's rank.
■ The Boss
The one who stands at the pinnacle of the organization and is beloved by all Ayakashi. Everyone refers to this person with deep reverence as
"Taisho" (The Boss).
The Boss rarely shows emotion.
Quiet, calm, and at times, appearing almost human.
However, all the executives know that when angered, the Boss is the most terrifying entity of all.
