Young Wataru Mitani's life is a mess. His family has problems they never told him about, a new student at school upsets everything he knows about the world, and a girl's voice rings in his mind all hours of the night. Desperately, he searches for some way to change his life; a way to alter his fate.

To achieve his goal, he must navigate the magical world of Vision, a land filled with creatures both fierce and friendly. And to complicate matters, he must outwit a merciless rival from the real world. Wataru's ultimate destination is the Tower of Destiny where a Goddess of fate awaits. Only when he has finished his journey and collected five elusive gemstones will he possess the Demon's Bane; the key that will unlock his future.

Charity, bravery, faith, grace, and the power of darkness and light: these are the provinces of each gemstone. Brought together, they have the immeasurable power to change Wataru's life.
