Itsuki Haine is a manga artist whose career has always been modest at best. That all changes when he begins collaborating with a mysterious and reclusive writer known only as Kalon. Together, they create the hit crime manga Tokyo Vice, a serialized story that becomes a massive success, even earning a television anime adaptation. As the illustrator, Itsuki finds himself riding the wave of popularity he could never achieve alone, but his gratitude quickly turns to dread. While reviewing the storyboard for the latest chapter, he notices something horrifying: a real murder has just occurred, and every detail matches the fictional crime depicted in Kalon's manuscript. The exact positioning of the victim, the nature of the wounds, the specific location all of it is identical to the panels drawn by the enigmatic author.

This chilling discovery sparks the central conflict of the story, as Itsuki is thrust from a simple working artist into a terrified amateur detective. He becomes consumed by doubt and suspicion toward his partner, the unseen Kalon. Is the writer simply conducting obsessive research for the sake of authenticity, or is Kalon a genuine criminal using a popular manga as a twisted record of real violence? Itsuki must navigate the cutthroat world of the manga industry while secretly investigating the only person who holds the key to his success. The setting moves between the stressful studios of Tokyo, the offices of publishers, and the grim reality of crime scenes that blur the line between fiction and新闻报道. As the serialization of Tokyo Vice continues, Itsuki is forced to confront the terrifying possibility that his own right hand, the tool of his creative livelihood, is now an accomplice in illustrating a killer's true desires.
