@cor3zone she sounds less annoying on the light novels, since we get to follow her thoughts better. Although I think part of that is intentional; she's intended as a foil for Bell. Since Bell is generally polite and well-likeable she ended a bit tsundere and bitchy.
@pip25 we don't because we're the only sentient race in Earth. It makes sense for elves though - they're a minority that has pride on its own race, calling each other «elf» is a way to say «you're an elf, behave as such».
@branscans thank you for the release!
nice to see some Lefiya fanservice.
