The man was almost wishing he had been killed already, sure he had a family and friends, but the pain was eating him. He was just a civilian so of course he didnt have a high strength against pain. Then he saw something he never wished to see. Right in front of his eyes he saw his family disowning him, and then being murdered by him, he didnt know that this was a simple jutsu. The man lost all willpower after this single move and was in a coma like state.
Kurokon then ripped the man's arm off completely and beat him awake with it, leaving blood and bruises on his chest. He then added fire claws to his hands and cut open his chest. He pulled his heart out while it was still beating and sliced it in two peices, instantly killing the man.
Kurokon then sighed and burnt everything around him to leave not even ashes of the man left. There was no particular reason he had chosen the man except to have fun and get another kill in, but something about the genjutsu he used was creeping him out. What if it happened to him? He would not be able to take it and would likely go on a rampage destroying anything in his path, but.... he wondered if anyone would dare to try to kill his wife.
He left and went back to his home in yukigakure, unaware of the purple eyes smiling down at him.
