Story
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.
