The Set-up: The Two Gangs and Truce and Conflict

The Kibutsuji Syndicate (Muzan's Gang): A high-tech, ruthless organization dominating the city's corporate and underground financial sectors. They deal in cybercrime, luxury smuggling, and high-end blackmail.
The Tsugikuni Clan (Yoriichi's Gang): A traditional, fiercely disciplined syndicate rooted in territory control, physical enforcement, and ancient martial codes. They control the docks, local businesses, and underground fighting circuits.
A brutal turf war has brought both sides to a bloody standstill. To stop the hemorrhage of money and men, the elders broker a truce sealed by an arranged marriage.However, there is a dark, unspoken secret. Years ago, a careless, collateral-damage bombing ordered by Muzan destroyed a rival building. Yoriichi's wife, Uta, was caught in the crossfire. Muzan has no idea he caused it; to him, it was just business. Yoriichi knows exactly who is responsible, but his grief has left him completely numb. He doesn't want revenge; he simply does not care about anything anymore, including this marriage.
