Since the recent disappearance of 8 Man, a mysterious cyborg super hero created by Professor Tani, the city reels under "terrorist" assaults from murderous drug-crazed street gangs. Hazuma, an ex-cop who now runs his own detective agency, is hired to track down a missing scientist alleged to have made off with cybernetics from Professor Tani's laboratory. The missing hardware is reappearing as psycho-activated weapons grafted onto the bodies of the rogue "cyper-junkies." During his investigation Hazuma is brutally murdered. Dr. Tani uses Hazuma as a bio-template to replace the missing 8 Man. As a cover, 8 Man maintains the original persona of the detective, yet must cope with the duality of the cynical private eye and maintain the balance as an emotionless super-android hero.

A satanic program is activated aboard a crowded commercial flight headed for Tokyo. It releases a swarm of invisible demons that send the aircraft plunging to a fiery doom. Everyone aboard is killed instantly - except Akito Kobayashi - owner of the devilish program and sworn ally of hell itself. 
Kojiro Soma, an old elementary school friend of Akito`s, is surprised to see him enroll back in school. Kojiro notices how this once lonely boy has grown into a suave and arrogant teenager. Later, when his classmates are attacked and legendary demons return to stalk to streets of Tokyo, Kojiro begins to truly understand what his old friend has become. 
Akito has plans for the human race. The plans revolve around magnetite, the mysterious element that forms the living essence of every human soul. Combined with his demonic software, a strong enough source of magnetite would release a plague of devils upon the Earth. That source exists in Kojiro`s class, but when the evil plan expands beyond even Akito`s grasp, it is Kojiro who must find the ultimate power within himself, and go head-to-head with the greatest demon of all!
