Wallman

Betrayed by the very country he once served, Jirou abandons his violent past as a professional hitman and returns to Japan. Stripped of his purpose and disillusioned, he drifts through life with complete apathy, convinced that nothing in the world holds any meaning for him anymore. He intends to leave the shadows of his former profession behind forever, resigning himself to an empty existence far removed from the underworld. However, his quiet resignation is shattered when he crosses paths with Nami, a fierce and active assassin driven by a singular mission: avenging her father's murder. Nami is no ordinary killer—she operates under the specialized designation of a "wallman," a unique breed of operative within the criminal underworld. Her unwavering resolve and dangerous path ignite something dormant within Jirou, pulling him out of his emotional exile. Drawn back into the lethal world he tried to escape, Jirou ultimately decides to join forces with Nami, stepping back into the fray to help her exact the vengeance she seeks.
