The Angel That Was a Demon

Summary

Ati is a quaint young priestess who's only just reached Summoner status in the Templars, a group of religious crusaders who fight demonic forces. During her ritual to summon her angel companion, she accidentally ends up summoning the demon, Iro. The two are now bound, but at what cost? Will Ori fight his own kind, and will Ati find what it takes to control and tame a wild demon?
