The ability to accidentally make every species orgasm is... Gift or curse? I just wonder why nobody asked where Sakura's horns are. Even the actual succubus nurse does have them.
I loved the lamia chapter, and it's true that basically every mythology around the world have a snake monster representation (the fight of a God representing the storms x the snake monster is basically present in every mythology)
Danger noodles exist almost everywhere and are always terrifying and dangerous to humans. Even cats have natural instincts to fear anything that is snake shaped. No wonder it's a common thing to associate malice with them.
But to be fair, there are also some differeng myths. Like a lot of Greek mythology. Nymphs were sometimes depicted with snake bodies and a lot of Poseidon's daughters were lamias too (although the actual Lamia from which the name originated was a woman cursed by Hera and stole and ate children, so that brings it back to evil).
Either way Lamias are pretty popular these days, so things are looking up for Nina.
