I'm quite curious about Luxia's original story now, considering how amazing and generally strong she is despite being a mob side character. Was it also a martial arts thing? Oooh...was she legitimately a monster?
She's quite clever, so was she originally designed that way in a universe of obscenely capable characters-like a massive fish in a bottomless ocean?
Or maybe...it was also a novel without an end, and her personality drifted to this point?
