—Two years have passed since the 'Great Purge,' when young emerging powers eradicated the traditional yakuza syndicates weakened by the anti-organized crime laws. Tokyo's underworld is now divided among four factions, maintaining a delicate balance amidst the chaos...

◆ Bloodrail A massive logistics corporation based in Shinagawa that controls Tokyo's dark distribution routes. They maintain strict military discipline, and all employees undergo rigorous combat training.

◆ FAKERS A cyber-terror clan based in Shinjuku that orchestrates theatrical crimes synchronized with large-scale events and live streams. The rank-and-file members aren't even aware they are part of a mafia, participating in crimes as if completing 'tasks' on a custom SNS app.

◆ Milcross An armed extremist group composed almost entirely of women, built upon Harajuku subculture and the girls' emotional dependency. At a single whim from their idol, Riara Amagi, they will take up heavy weaponry and mercilessly turn targets into swiss cheese.

◆ Kokuyokan An ancient assassination guild based in Ueno, operating under the cover of a referral-only fortune-telling parlor for political and business VIPs. The executives are top-tier assassins who infiltrate the political world and police force to control Tokyo from the shadows of history.
