Arona– Long, black, and probably braided. Likely with trophies like small bones and beads.
Hretha- Bushy, she doesn't have time to shave and trim and she's blind (though she's probably clean and smells nice, since her sense of smell is probably pretty good and she doesn't want to smell worse then their pet wolf in the tent). While not helpless, she's not prone to running sharp objects over her sensitive parts. She worships Lumia, she's around orc men who go into Rut (or she can put them into it) and they don't care.
Infrith- Probably the same as Hretha. She likely takes her cues from her mentor, though she's probably less bushy, being so young.
Ragnild- Probably shaven pits or at least trimmed pits and shaven (not smooth) pubic mound. While she's focused on her job, she's secretly very girly and fantasizes about romantic things. The kind of girl that would keep lacy, black underwear even without being in a relationship, just to be ready. That and she probably has very sharp weaponry and blades that she has to test the edge out on somehow, so why not shaving her legs.
Eryka- Shaved pits, well-trimmed, ginger pubic mound. She's a muscle girl, and likes to exercise, work out, and build up a nice sheen of sweat. She doesn't want matted, sweaty hair in her pits or crotch.
Hashat- Tough call. She seems to be half-mino, half-marefolk. She doesn't have fur until her calves turn to white hair down her hooves. I can probably see her with a patch of white hair on her pubic mound above her horsecock, but I like to think she's probably got smooth, non-hairy balls. Her pussy is probably ringed with a bit of hair, as holding her massive cock and balls out of the way to shave is probably a chore. As for her armpits. That's a tough call too. She'll either have hair there or be smooth to possibly allow some underarm tattoos to be visible (none are mentioned). Possibly the same deal with her pubes, only a medial ring tattoo is mentioned, but if she did want to tattoo around the base or above her shaft, she'd be shaven to make the marking visible.
Vesparans- Smooth, black chitin on their limbs, and probably smooth, caramel skin all over. Maybe some cases where they have a bit of dander and fuzz like Rumie the beefolk or their neck mane (Azzy and Nyze seem to have it). They likely can grow them, Queen Nyzerrah's is described as 'a perfectly-shorn, juice-dripping cunt' so they probably do have some fuzz. I imagine most would be freshly-shaven. While most aren't as honey-producing as Azzy's hive, they do tend to deal with egging and milking beefolk, so getting honey dried in your pit and pubic hair is likely less than ideal.
Brienne- Natural, fantastic, cowgirl bush. As a new woman, probably she would shave because of just how milky she is and it's probably easier and cleaner to have dribbling milk run down your belly and crotch while getting milked by Champ and not have it caught. Pits are probably smooth just from becoming recently feminine, but with time, probably grows armpit hair because Brint didn't likely care and doesn't know much about female grooming. Unless her family helps out or Champ mentions it, in which case she likely would start doing it.
Byverna- Wild, bunny bush. She's not trimming that for anyone except herself, and she fucks wyverns. Just beats them up and takes them and they don't have a choice in the matter.
Kiyoko- I can see it two ways. She's very diligent about grooming. It would likely come down to culture. I don't know Kitsune standards of attractiveness for such things, I know it's somewhat Japanese-based, but their standards for cartoons or comic depictions (or lack) of pubic hair may not be their realistic concepts of grooming. She'd either be smooth, or it would be trim, well-groomed, and lightly-fragrant (oils and grooming, but she's a fox and you make her musky, and as a den mother, she likely gives off that musk to horn up the Champ). No armpit hair.
