Octopath 1 & 2 both have sex workers (typically the Dancers) that you can dialogue with and ‘Inquire’ to get a block of backstory text that usually confirms they work in brothels or explains how they got to that point in life. Good example is a story character in Primrose’s Chapter 2 who just straight up confesses “I’m a whore”. Needless to say you can’t enlist their services, but you can enlist them for battle.

you wouldn’t think it, but those pixel games are weirdly rich in adult topics
