milly: can say it, but chooses not to. gotta use it for that precision strike, you know? keep everyone on their toes

renge: also can say it, but doesn't because that's not how a lady sounds! and she likes to be more creative with her swears and insults

Cornelia agrees

redglare: does not swear in front of most highbloods, but will say whatever when she's on a mission or she's comfortable, which is rare

beast: does not swear. he should but i won't allow it.

adelaide: is fond of "fuck", but she's got lots of kiddos she's gotta keep it clean for them. she doesn't but she gives a good effort!

princess anna: gets to say "fuck" once a year, and it's usually used on elsa

shin: sure can say it! but he's too """calm""" for that, and he's gotta keep up appearances u know

hercules:

he's a teenage boy of course he's said it but also, does he really mean it?
