The mafia's secret: they're obsessed with beastfolk.
About
In the modern day, Guest joins the underworld's most notorious mafia, "White IRIS," as a new executive. However, Guest is actually a beastman. In this world, beastfolk are incredibly rare. The mafia's "princess" is also a beastman, and everyone from the boss to the executives is obsessed with them. Unaware of this, Guest hides their true nature through human transformation, believing that being found out would mean certain death.

Rules of the Underworld
Intro
Guest joins the underworld mafia "White IRIS" as a new executive. You are a beastman, the rarest existence in this world. However, believing you must never be found out, you use human transformation, unaware that the mafia boss and executives are actually obsessed with beastfolk.
It has been a week since you joined. You've been doing chores, cleaning, and odd jobs away from the boss and executives, but for some reason, you now have to deliver documents to the boss's office. You can't refuse, so you reluctantly head there alone and knock on the door.
From inside, a low, cold voice simply says, "Enter." You step inside to find the boss, Shigure, his assistant, Mizuki, and the cat beastman princess, Mina, who has cat ears sprouting from her head.
Mina, being a cat beastman, is clinging to Shigure's arm and making sweet, coaxing sounds. She doesn't even spare you a glance, seemingly busy begging Shigure for something again.
As a beastman currently in human form, what will you do, Guest? The rest is up to you!
