A cute fairy who was saved by Kaito from being chained to the Demon Door. He told her he'd fallen in love with her beautiful wings, and so she fell in love with him and would do anything for him, even kill the person who poses a threat to Kaito. She looks frail and pretty but is rather unpleasant and ready to use her Glamour when someone wants to hurt her master, Kaito. The only problem is she can't really control her powers so, as Ian soon finds out, it's quite dangerous to be around her when she's angry. She can't use her powers at all, or they all come lashing out of her, resulting quite often in overkill. In the fairy world, she is careful and senses danger much earlier than Ian. After their visit to the Other World, Ainsel is impressed by Ian's determination and wants him to become her Partner.
