Berserker a term used to describe a person intoxicated by blood lust lost in battlefield while being bathed in blood and gore that is one who had seen Ryuu would describe him, he moved from one person to another hacking, slashing, biting and stomping using every possible way to kill and maim his enemies, and like any good berserker he had already ceased paying any attention to himself, if it were any other person he would have already succumbed to their injuries received from the various attacks send towards him but fortunately for Ryuu the armor created by his teachers protected him.
As the fight raged on the blood like aura clung to him like a robe woven out of blood which only seemed to increase causing Ryuu's strength to increase as well as his insanity.
