I imagine this is how demons feel when we call out their names.
"I know who you are! Reveal thyself, Belphegor"
"Oh— How embarrassing! How did you know my name? It sounds so chuuni now, I can't~~."
@That-Guy Maybe the names of anime characters actually have the same power as demons and that's why saying their first names is such a big deal to them.
@Faulheit
1st - First name
2nd - Shortening of first name, i.e. nickname
3rd - "[First name], son/daughter of [parent names], defender of the Astral Planes"
4th - First name in morse code
