Honestly, I do dislike the kitsune more and more as the game goes on, but it's less because of their attitude and more because of how bloated they are.
Back when the sum total of our kitsune interaction was a lone waifu who gave us fun sex-dreams, a cute daughteru, some neat romantic interactions and an extra summon, I was good with it. Now we've got that, plus a main quest dungeon, plus multiple sidequests, plus two wandering enemies, plus a whole navigable multistory treehouse of like a dozen named and portraited NPCs (all of whom are assholes, with the sole exception of Kohaku), each with excessive reams of their own exposition about the kitsunes' very important and super tragic and totally relevant culture/history/religion/alcoholism, and also our daughteru underwent a mandatory offscreen timeskip and gets mad that we were a deadbeat timeskip dad and ends up with some rando hitherto-unseen boyfriend. And I'm expected to care about... all of this.
At this point, I care so little about such a large and aggressive chunk of the game that the last time I started a new character I literally just left Kiyoko's necklace where it was. She was the only good thing about them, but I ditched her because she's a gateway to so much horseshit. Dealt with the foxes the bare minimum possible, tapped through their woe-is-me weebery, headed back to Lady Evergreen and never spoke to any of them again. I hope to god the kitsune aren't getting any more content, because they already feel like a tumour.
