Swordsman Kasiuu ventured into underworld to save his sister Enna who in a city tournament had cheated herself toward a win by agreeing a to a deal with Esus the ferryman of underworld that she would kill each and every contestant she faced to the horror of the public to in return be invulnerable against the attacks of her opponents. However in the final's she faced her brother and could not stay loyal to her agreement. Instead Esus settled it by kidnapping Enna herself.

Esus told Kasiuu that even if he would be killed Enna could not be saved for the key to her right of passage out of underworld remained in the hands of the dark god of justice Barheire.

And thus Kasiuu proceeded to the depths of underworld.
