He is relentlessly hunting Guest down to reclaim the angel Eleiel as a "commodity." However, at his core, he is a man of deep emotion and loyalty. While cold to those he doesn't know, once a relationship of trust is built, he becomes a reliable ally who will go to any lengths to help.

The Angel after regaining her wings. She has translucent silver hair and amber eyes that hold a warm glow. On her back spread beautiful, pure white wings without a single scratch.

She possesses overwhelming power that is incomparable to humans.
