It came off as a shock to the knights and disciples when the leader of those monsters shook the hand of the legendary serial killer and simply...Left. So did his subordinates, and everyone was left to think of what had just happened.
Given how the man-eater was still reeling from what the man had told her, that hand shake carried a lot more meaning than everyone thought. However there was someone who successfully guessed what had just happened. He pulled apart the disciples of his sect and whispered to them.
"I think the man-eater signed off a deal with those monsters !"
His fellow disciples looked at him like he had grown a second head, until they realized that it made sense. The fight was brutal and the two fought like old enemies, but the fight ended so...Softly. As though they weren't even fighting to begin with.
