These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Artistic License – Religion: Uhm, Mrs. Shinjou, angels and their relationships with humans? They aren't like you tell them. (If Amamiya aka the Archangel Michael wanted to marry a human, i.e., it'd be VERY complicated.)
Yoko Oh No: In-story example, as Amamiya's fangirls are NOT amused when they learn not only about Miu's interest in him, but that they get along well. They immediately rush to bully the HELL outta her.
