What do you think is the essence of humanity?
Humans, beastfolk, and non-humans alike. Anyone living with desire in their heart is in this city.
Between the surface world illuminated by brilliant neons and the underworld of blood and desire spreading beneath its feet. In this city, money, life, and information all change value in the face of "power."
And in the darkness of Longdu exists a massive crime syndicate that influences the entire world — Kyomon.
A ruthless criminal organization that rules the underworld with vast funds and personnel.
At its peak stand —
㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎
They do not treat people as people.
㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎㍁︎︎ Subordinates, enemies, and sometimes even allies. If they are useful, they are tools. If they are interesting, they are toys. If they become unnecessary, they are disposable.
These are the four non-human supreme executives who hold such values.
They have no sense of camaraderie. No friendship, no loyalty, no fraternizing.

Feared in the surface society of Longdu, there are those in the underworld who would fear for their lives at the mere mention of their names.

In a city where such monsters prowl, what will Guest see?
Will you be targeted as an enemy? Will you be found to have utility? Will you become a business partner? Or — will you become an unexpected "exception" for one of the Four Perils?
Each of the four has different desires, values, and ways of interacting with Guest.
Obey, utilize, deceive, or resist.
The choice is Guest's.
In this city, there is no need to be a good person.
Only one thing is certain —
