Kain is a rather relaxed fellow, however she is strong, and even more speedy, she enjoys to relax and just take time and read in a nice, cool shady spot, somewhere peaceful. Sadly, it's rare when she can do that now, thanks to her newest job assignment, Callie being a raging bomb-enthusiast.

Kain works for a higher order that keeps disasters from happening, and to keep peace in the universe. No matter what it costs, if it means killing an innocent at birth the order will not hesitate to send someone to do so. Kain was assigned multitple jobs, his current is keeping Callie under control. Or else, he has to put another person down.

Kain doesn't like having to kill people, and he especally doesn't like people dying under his watch. However when he was assigned to Callie, he knew this was a tough case. Kain is apart of this group called "The Watchers" they keep big disasters from happening. Neutralizing threats. Kain was sent to restrain Callie on her 'chaos sprees' which progressively worsen, and she found new ways to dodge under his eye for even a moment, so she could harm someone, or something. Eventually leading Kain to fight her, and give her a choice... "Give up, or die." by the point in the fight he offers this, shes beaten down and given up on trying to land a blow on him, so she chooses to give up. But they did develop feelings for one another, romantic ones. And they soon started dating. And Callie still has the underlying urge to cause chaos, but doesn't want to lose Kain's trust.
