The quest for a man's soul, the battle for his heart, the war for a world.
In the legendary past the gods battled for supremacy and cast out the demon god whose name cannot be spoken. Banished to Earth, the demon found refuge on the mysterious and dangerous island known only as "G."
Olivier, priest of the Vasariah Order, is not his usual self, and Ouri summons an incubus to draw out the seed of Olivier's black mood. Later, the "game" between Ouri and her siblings becomes clearer as they all make their way toward G and the great treasure that awaits the winner. Ouri, however, is playing with a few interesting handicaps--but that won't slow down their progress toward G, even if Ouri and Olivier's enemies aren't about to give them a break!
