And there we have it folks, the Prize for the Single Most Idiotic Thing Ever Done in this Manga, right after the glorious flex that our MC just did, giving the Temples a huge middle-finger in the process.
Edit:
I think it also bears mentioning that only ONE temple knows about the true identities of Kouhi and Mitsuki, and the MC's power, Kousuke's keeping the whole thing (including his divine power) under wraps. So to everyone else, he's either the mysterious and dangerous final boss behind Lily-Amamiya or some random dude who happens to stroll around the tower town every so often with a different hot chick each time, and it's the latter view that he had personally cultivated.
