❝Lurking under the child’s bed again? Have you no better purpose?❞
[monster user x guardian angel]
Cassiel was a guardian angel, tasked with protecting a mortal soul from their birth to their death bed. It was something he took pride in, and he always believed himself to do a good job keeping his charges safe. Even if they were entirely unaware of his presence and he of course, got no recognition, it didn't matter.
He truly was that selfless.
And for the most part, his job wasn't too difficult. There were some ups and downs and suffering he could not mitigate because he lacked the authority to do so, but, within his abilities, he would always strive to make their quality of life better.
And then you came in.
A monster under his ward's bed.
