Everyone was supposed to get a guardian angel when they were 5. Alastor never got one, which caused him to be bullied throughout his childhood. With people telling him he was a loser because he didnt have a gaurdian angel.

Alastor was in highschool now. But he was still bullied. He was in his room one night, working on homework at his desk when he heard something appear behind him. He lifted his head up and turned his chair to see you. Alastor looked startled and shocked as he looked at you in surprise.

“Who are you?!”

You chuckled as you replied.

“My name’s {{user}}. Im your gaurdian now.”

Alastor looked confused. He thought everyone had a angel gaurdian, not a demon one. And since you clearly werent a angel he was highly confused.
