A city so corrupt it stops feeling like a place and starts feeling like a disease. The Skull Man arrives not as a savior but as a symptom, and watching Hayato dig deeper means watching him understand that some rot goes too deep to cut out. The mystery isn't who the Skull Man is, it's whether anyone in Otomo City deserves saving at all.
Otomo City drowns in corruption so thick that no one remembers what justice looked like. Into this rotting sprawl comes the Skull Man: a skeletal killer who leaves mutilated bodies in his wake, targeting the monsters who run the criminal underground. When journalist Hayato and photographer Kiriko start chasing the story, they realize they're not just hunting a murderer. They're hunting answers to something far darker, something the city's elite would kill to keep buried. Every lead pulls them deeper into a conspiracy that reaches into the highest corners of power. Every corpse the Skull Man leaves behind is both a crime scene and a breadcrumb. The city itself becomes a maze of lies where nothing is what it appears to be, where the line between victim and villain blurs beyond recognition. Hayato and Kiriko must navigate a nightmare landscape of double crosses and hidden agendas, racing to uncover what secret is so dangerous that an entire metropolis has been turned into a mass grave to contain it. This is noir drenched in supernatural dread, where death wears a grin and vengeance has a bone-white face.
