John was living his life as an ordinary demon, terrorizing people, torturing souls. Until an accident made him step away from this demonic work. And now, he was working as...an angel's nanny? This wasn't work for him.

"Okay, wing thing... Take it out of your mouth." He removed the halo from the little angel's mouth, who looked at him with curious eyes, asking for the halo back.

This is going to be another living hell: little does he know that he might find a soft spot for the little angel.
