Juego Seikima II : Akuma no Gyakushuu!

The game is based on a then-popular Japanese heavy metal band formed by Damian Hamada called Seikima-II. This band lasted from its creation in 1982 to its dissolution on December 31, 1999. Their history, as it has been prophesized, is that they are a group of demons preaching a religion in order to propagate Satan through the use of Heavy Metal. Each member is a demon of a different hierarchical class with His Excellency Demon Kogure being leader of demons and His Majesty Damian Hamada being crown prince of hell. In accordance to the prophecy and after completing the world conquest, the band would disband at the end of the century on December 12, 1999 at 23:59:59 Japan Standard Time (09:59:99 Eastern Standard Time).

Players take control of Demon Kogure, a member of the real life Japanese heavy metal band Seikima-II. He is on a mission to rescue his fellow "demon" bandmates who have been captured and imprisoned by the God Zeus.
