B: The Beginning

Synopsis

In the city-state of Cremona, a shadowy vigilante known as "Killer B" wreaks havoc with a blade and extraordinary abilities, dispensing justice while drawing both admiration and hostility. The Royal Investigation Service (RIS), unable to capture this outlaw, recruits Keith Flick—a talented but unorthodox detective reassigned to the Archives Department after a personal tragedy. As the killings shift from quiet eliminations of criminals to bold attacks on key figures, it becomes clear that multiple individuals are involved. Aided by his impulsive partner, Lily Hoshina, and surprisingly, Killer B, Keith delves into a web of conspiracies involving secret groups, domestic terrorism, and illegal human experimentation. As the RIS oversteps its bounds, the full extent of government corruption and the reliability of those around Keith come into question.
