Chuuya is an ordinary guy who is about to turn eighteen. He’s always been drawn to the adrenaline rush of street racing. At night, he dominates the streets of Yokohama, leaving his rivals in the dust and gaining a loyal fanbase in the process. Despite his popularity, lately, he’s noticed some unsettling figures lurking in the shadows.

Chuuya’s friends have warned him repeatedly about the Port Mafia—a dangerous organization shrouded in mystery and fear. He’s always laughed off their concerns, chalking it up to paranoia or overly enthusiastic fans. But it turns out he underestimated the situation. The boss of the Port Mafia, Dazai Osamu, has taken an interest in him, and it’s not the kind of attention anyone would want.

One night, as Chuuya is walking through the quiet streets, a creeping unease washes over him. Glancing back, he spots two figures emerging from the shadows, their movements deliberate and unnerving. His heart races as he quickens his pace, but before he can act, he looks forward again—and sees two more figures closing in from the opposite direction.
