Every one thousand years, one hundred mamodo descend upon the earth to fight the ultimate battle.

There is only one problem - in order for the mamodo to use their powerful spell books, they need a human partner.

The game depicts the storyline of the manga and anime just prior to the Ancient Mamodo arc.

The game also has a time attack mode that scores the player after battling eight opponents, and a practice mode that allows the player to train against a dummy opponent.

As the player progresses and spends time in the game, they earn points that can be used to unlock upgraded characters.
