The Black Iron Beastmen had always been considered the barbarians among Beastmen, powerful but without technique. However, that old guy was different... He never used the Black Iron Beastmen's iconic large blade. His sword was only a bit over a meter long, which wasn't much longer than a dagger for Black Iron Beastmen.
But that small sword dismembered innumerable enemies and had drunk an unknown amount of blood. His fighting style, if put in mankind's world, would be similar to an art. It was completely different from the Beastmen's use of raw power and instincts to create opportunities.
His most exaggerated feat was when he faced a 9th Rank Archmage that was using an 8th Tier Meteor Fall. He used that shortsword and sliced that several-hundred-meter-wide meteor into pieces in less than three seconds.
Sunderer was his special title!
