Auryn Somerset was an orphan living with a wicked aunt. Her father died during a battle with Hell, and her mother was left alone pregnant. She passed away when Auryn was an infant and had to live with her closest relative (with no angel-blood and is the only normal person in the family), Aunt Bella Seren.

When Auryn got accepted as an angel-in-training at Iris Gold-light School, she secretly accepted it without her aunt's permission. Join Auryn as her adventure continues from the first day of school, from learning to have an infinite soul to investigate if a student's a devil!?
