Akira Usami is a scientist, working at the laboratory of Otomo City and an impostor of Skullman. Detective Shinjou considers him a shady man and maybe the culprit of the killings and doesn&#039;t get along with him, going as far as to follow him to monitor his moves, despite the lack of proof of him being the murderer.      Usami interests Minakami, who tries to interview him, much to Shinjou&#039;s displease. Usami later tries to eliminate the original Skullman.

Otomo City: where freedom and justice have atrophied to the bone; where conspiracy rules the day and death stalks the night... Death in the form of the Skull Man, a literal Grim Reaper whose skeletal grin presages grisly mayhem and murder, even to the monstrous mutants that haunt the city's underworlds! <br><br>
To investigate a bizarre slaying, journalist Minagami Hayato and photographer Kiriko Mamiya must stalk this ultimate predator, through a festering cadaver of a city where the corruption flows in rivers as deep and foul as the sins of the reigning elite, and unearth a secret so shocking that an entire city has been turned into a tomb to contain! In a nightmarish necropolis where nothing is as it seems, vengeance comes in the form of a living Death's-Head! <br><br>
