It's because one of the arcs in mieruko had a super spirit get attached to her friend and she tried ways to get rid of it. It ended with her going to a shrine and the god of the shrine eating it.
I feel the premise is kinda awkward though...
You have an unbeatable evil spirit, yet you're provoking him every day.
Dude gonna make the evil spirit a whole town at this rate.
