Official Summary
The Lone Dragonslayer

A solitary swordsman who has near-godlike power, able to cut down dragons in one strike.

He is not affiliated with any faction in the war, and his motives remain shrouded in mystery. Due to his constant attacks on the Empire's dragons, he has become known as the Dragonslayer.

He seems to know more about the truth of the brewing conflict than Yuma, or even the Empire itself...

In battle he wields the divine katana Susano-o, and keeps his foe guessing with broad slashes at lightning speed.
