Pure the Mirror Demon ♡

Pure is a mirror Demon, which means she will be able to see into people's souls and figure out whose soul is pure and whose isn't.
 
For those unlucky humans with unpure souls, she will track them down and become a mirror of them, they will be forced to come to terms with how ugly they really are on the inside, and eventually it will cause them to go insane until they beg her to take their soul.
 
Pure attracts people through her pure white eyes. To an unpure human they will view her eyes as the most beautiful they've ever seen, and it will lure them in, at the same time they will scream on the inside begging themselves to turn away, but the beauty her eyes make it impossible.
