The game is based on the Bikkuriman animé series. Once upon a time, the world was a peaceful place. Three races - Angels, Demons, and Talismans - co-existed in the world, protected by the Holy Goddess Nadia. One day, Nadia sent her twin children into the world. Jura, the head of the Demons, abducted one of the children and devoured it. The other child took refuge by the Angels and soon became their leader, known as Super Zeus. He led the Angels to a victory over the Demons. But Nadia, seeing how her world is being torn apart by the war, split it in two. Years have passed. You are a young hero named Yamato Ouji, raised in the world of the Angels. Super Zeus sends you on a quest to find other Holy Warriors, to re-unite the worlds, and to bring everlasting peace to all the races.
This is a traditional Japanese-style RPG. You navigate your hero from a top-down view on the world map, in towns, and dungeons. The enemies are random and the combat is turn-based, viewed from first-person perspective. You start alone but later you find other heroes who join your party and help you on your quest.
