perhaps
Okay - hear me out:
Rae - bunny
Naomi - octocpus or gorilla
Cait - fox*
Lyriel - cat*
Yona - bear
Blair - cow**
*: Though, now that I give it more thought I'd almost swap the two. I feel like Cait both in her timid personality and har name being (almost) cat gives me more cat vibes while Lyriel feels more "wild" and so the image of a fox seems very fitting.
**: Yes it's the udders. Also ever since you used that promo image: Pierced nipples when?
