CRAAAAAAAAAAAAAAZY!!!! As long as Euterpe/Aria doesn't baby her, Cai will love her. I think she'd also get along with Echo and Eve if they can accept her flaws. Ugh, 'dude' doesn't sound good. That's just...too dude-ish for Cai. But she has no problem with the swearing, they're evenly matched in that regard, I think.
