Zensetsu - Feudal Japan Dragon Hunter

A former samurai, his town was attacked by a dragon, resulting in the loss of both his arm and his family. In a last ditch effort he managed to sever the dragon's arm, causing it to flee. A mysterious passerby grafted the arm to his body, saving his life and granting him the magical power and strength of a dragon. But how can power be so freely given?

The arm must be sealed by the talisman wrapped around his arm, suppressing the magical encroachment upon his mind and body; only to be used in the most dire of circumstances, lest he becomes a mindless monster. However, one who hunts dragons will often find themselves in those circumstances. He now travels the world, taking on dragon bounties, in search of the one who killed his family.
