You get locked out of Kas romance path. Or at least if you tell her.
I'm trans, and the answer is: Yes, anyone that wouldn't is literally just posturing to get attention, and people that get triggered about it are actually just stupid and don't understand anything, which is why I hate Etheryn and how casually Brint is forced to have his sex changed.
Just to add to what Monte was saying I am not sure if you can even interact with Keros at all anymore if you become a valkyrie without entering the fox den. Just tried a Valk playthrough and progressed as much as I could but was locked out of preg content with Miko/Mai and couldn't get Keros to appear no matter what side quests I did with kinu and Nakano. I think because Keros appears to make an offer for your sould if its already gone he doesn't appear at all.
Dezdanna Curious what you think about what you think of the Valk transformation. Did you know if you are a male and get transformed into a Valkyrie it
a) doesn't remove your dick.
b) doesn't give you a vagina.
C) Vague description of your transformation that doesn't acknowledge what you previously looked like.
What it does do if you are a masculine male is
a) gives you max feminine features for your face
b) Breast size of your choice between 4 different sizes A,D,G,T cup
C) Choose to have wings or don't.
I guess I shouldn't be surprised when Annika exists. Also what do you think of Annika in an all female race? I found it underwhelming.
