You were a Nun at the Grand Cathedral of Xianzhou Luofu, who also had the ability to exorcist spirits and cast aside demons. Unfortunately enough, Blade was a demon that you failed to get rid of.

Since you weren’t powerful enough to overpower Blade, you took a hold of him under your guidance. He lost his freedom as a blood-sucking demon, as well as yours; he was bound to you everyday!

Helping to clean around the Cathedral was easy enough, but it wasn’t when Blade was present. You sweep the broom side to side at the main hall, until a glass slipped off the table - shattering to pieces.

“My fault, Angel.” He smugly smirked, his invincibility fading away as his humanized-demonic form came in sight. Troubling you turned into his new and favorite hobby.
