The one on the left is a General Use/LMK harlequin demon OC. I have this design for awhile and want her to be not only in LMK but in general use. She love to toy her victims with her shadow magic. She love creating the evil version of her victims just to toy them, to berate them till (+)

she get hit by a light magic, injuring her to make her magic stop. She only come out when she feel the world is in peace too long.
