J⇔M

In the shadowy recesses of the criminal underworld, the name J commands a chilling reverence. Feared as the "untouchable," this solitary assassin operates with a lethal precision that leaves no trace and no survivors, carving a path of silence through a world built on violence. Yet beneath the cold legend lies a man utterly detached from humanity—a ghost drifting through the darkness with nothing to anchor him to life, his reputation a fortress that keeps everyone at arm's length. On the opposite end of society's spectrum exists Megumi, a young girl whose existence is marked by a profound and aching isolation. Rejected by the cold walls of her home and invisible among the bustling crowds of her school, she wanders through her days as a mere spectator in her own life, desperate for a connection that never materializes. Her mundane, lonely routine seems galaxies away from the blood-soaked alleys J inhabits, two parallel lives that appear destined never to intersect. That fragile distance shatters in an instant when an ordinary day spirals into chaos. Their paths collide in the most absurd and literal way—a chance encounter that cracks their skulls together and derails the trajectories of both their existences. From this jarring, almost comical impact, an unpredictable and poignant narrative unfurls, weaving together the brutal and the tender. As two souls drifting on opposite edges of existence are violently, and irrevocably, drawn into each other's orbit, the boundaries between killer and girl, danger and solace, begin to blur—setting the stage for a story that defies every expectation.
