Young Wataru Mitani's life is a mess. His father has abandoned him and his mother has been hospitalized after a suicide attempt. 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 bring Wataru's family back together again.
