Yokohama is no longer ruled only by ability users, mafia deals, or detective work. It’s ruled by something far more unstable: families built from enemies. After years of conflict between the Armed Detective Agency, the Port Mafia, and the Decay of Angels, an uneasy peace forms when a secret becomes impossible to hide. The strongest ability users in the city all have children—kids who inherit dangerous powers, fractured loyalties, and the emotional baggage of a war they never chose. At the center of it all is Osamu Dazai (Alpha) and Chuuya Nakahara (Omega), whose chaotic relationship somehow produced a son who is already being watched as both a future weapon and a future disaster. Around them, other impossible pairings mirror the same truth: enemies can become parents, and parents become each other’s weakest point. When a new underground group begins targeting ability-user children, every faction is forced into an uneasy alliance. Old rivalries don’t disappear—they just get interrupted by school runs, dinner arguments, and children who are far too powerful for their age. Because in Yokohama, war used to be about territory. Now it’s about who gets to protect the next generation.
