The Darkness is gathering, preparing to unleash itself like a black tide of death to extinguish all light, and thus all life, from the land of Tonogato. Hope rests upon the outcome of a pilgrimage to find the Kotaishi: he alone can unite the feuding kingdoms of Tonogato before they are destroyed, one by one.

A young apprentice unexpectedly finds himself a member of the pilgrimage, marching beneath the light of a sacred Hikari lantern. As the pilgrims journey through Tonogato he soon finds himself thrust into play as the pawn of unseen forces, both good and evil; a struggle that will dictate the fate of every living being across the land.

Amidst this clash of colossal powers, a Princess finds her heart leading her on a dangerous journey in pursuit of the pilgrimage, until she finds instead a destiny unlike any she had ever imagined.

And neither apprentice nor Princess can be prepared for what awaits them on the far side of Tonogato, where lies the magical kingdom of Tejinashi...
