Silent Thief

'Damn it...'

Adrian cursed as he stared at the figure towering above him. The demon was wearing a strange white mask with empty black eyes and a black steel armor over his body. He had long white hair that waved peacefully as the calm wind blew past them and was about six feet tall if not taller. 

The strange demon tilted his head and stared at the destruction the mage had caused…

Corpses. The boy was surrounded by a grotesque display of carcasses of the demonic abominations that had dared to attack him. Most were crushed, their bodies barely recognizable, others were twisted with some parts facing abnormal directions. They must have had the most painful last moments before death. 

"I wasn't told you were this powerful. The beasts were of Class A monstrosity, some even mage types. I'm fathomed."

The demon's voice was indifferent, not giving away a slight hint of his emotions, if he had any.
