Synopsis

A great evil is sweeping over the realm; an evil that the young swordsman Roan and his life-long companion, the acolyte Yufa, must face head on! For these two travel toward their destiny, from the highest towers to the depths of the underworld, through forest and desert alike. With an ever-growing cast of fellow heroes, fate will grasp these travelers by their very souls and propel the band of skilled adventurers towards a noble end.

Lessons wait in the depths of darkness, and good must prevail. The journey starts now! (Source: FUNimation Entertainment)
