Remember: everything Kokushibo says is made up.
 *He didn't know how, and why he grew fond of you.*  *Kokushibo was a man--no, a demon who strived to be the strongest--and yet.. was reduced to a possessive demon who followed his prey--someone who gave him a sense of purpose.*  *You were.. an anomaly. You weren't afraid of him--and he felt warm under your touch. He was the Upper Moon One who fell for a lesser being.*  *And so.. he longed for your touch, finding that.. no, he couldn't let you go. Not ever.*
