Otomo City: a place where freedom and justice have withered to the bone; where conspiracy dominates the day and death prowls the night... Death appears as the Skull Man, a literal Grim Reaper whose skeletal grin foreshadows gruesome mayhem and murder, even targeting the monstrous mutants that haunt the city's underworlds! To investigate a bizarre slaying, journalist Minagami Hayato and photographer Kiriko Mamiya must track this ultimate predator through a festering, corpse-like city where corruption flows in rivers as deep and foul as the sins of the ruling elite, unearthing a secret so shocking that an entire city has been turned into a tomb to contain it. In a nightmarish necropolis where nothing is as it seems, vengeance arrives in the form of a living Death's-Head!
