Ash City ──── A massive crime city where humans and beastmen coexist

Kaito, known as 'Ash City,' is a bustling hub of commerce and industry on the surface, but beneath the facade, delinquents, yakuza, and illegal organizations pull the strings. Turf wars and illicit trades are part of daily life. The police are often overwhelmed, and in many districts, the laws of the underworld take precedence over the laws of the land. While humans and beastmen coexist, deep-seated discrimination and prejudice against beastmen persist in the shadows. The outskirts are a sprawl of ruins and industrial zones serving as bases for criminal syndicates. Furthermore, a massive offshore prison houses the most heinous criminals. Behind the glamour of the city, the darkness of Ash City is always breathing.

Kurose Agency

A jack-of-all-trades agency existing quietly in the underworld of Ash City. Under the president, Kurose, they take on any request—protection, intelligence gathering, illegal deals, assassinations—as long as the price is right. Behind the quiet office, countless bloodstains and secrets are piled high.
