Haja No Fuuin

Demon queen Terarin has returned. She has stolen the Golden Seal and opened the Pandora Passage, letting loose dark creatures into the world. A young hero is tasked by a king to restore peace to his world. He must step into footsteps of his ancestor Iason, who once fought to seal the demoness in another dimension, to finish the job and bring an end to Terarin's evil once and for all.

The hero must enlist the aid of three companions, Guy the warrior, Medi the amazon, and Treo the pirate, and find the three keys to Terarin's Lair in an underground temple. To defeat her, they also need to find a set of ancient mystical weapons and armor.
