Sariel

Sariel is a stray angel tasked with protecting the planet the story takes place on. Even though she doesn't show much emotions, Sariel is kind-hearted and cares for the people in her world more than her own well being. Sariel is more powerful than many gods, to the extent that it would have needed all dragon gods on the planet to have a chance of defeating her. She is capable of seeing through D's darkness. As a combat specialist, she is poor at performing detailed analysis of magecraft.
