Seikima II - Akuma no Gyakushuu!

Seikima II: Akuma no Gyakushuu! is a single-player action platformer where the player controls Demon Kogure, the vocalist and leader of the Japanese heavy metal band Seikima II. The story follows the band of demons who must rescue their kidnapped members from the Greek god Zeus across four stages. Gameplay involves platforming through short zones while collecting collectibles such as band member heads, money bags, ghosts, and power-ups; players throw rocks, axes, bats, or firebombs at enemies and use bought instruments for the good ending. The life meter drains continuously, requiring lifeblood potions, and jumping controls are awkward with no holding jump and mid-air direction changes. It stands out as an early licensed video game based on the band Seikima II (formed 1982, disbanded 1999), featuring band members like Jail O'Hashi (guitar), Raiden Yuzawa (drums), Ace Shimizu (guitar), and Xenon Ishikawa (bass), plus Zeus as the final boss.
