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.
From my point of view, when someone takes the trouble to write so much just to distill his hate towards fictional beings, he automatically misses an argument!
If I wanted to read long texts about why such a thing / person was the biggest atrocity to walk the earth since Hitler or Stalin, I would go to facebook, where I can find Yottabytes of it!
In addition, kitsunes are the kind of characters you either love or hate, because they are made to be like real people, with qualities and flaws!
From what I see, these xenophobic vampiric fluff balls are the most humanized characters in this game! I would say that the only thing missing from them would be the opportunity to change their negative view of other people (not that valuing their culture in the first place is necessarily a bad thing, but when you start treating other people badly for considering them inferior, this stops being pride and becomes prejudice) and a little family therapy to help with the emotional problems of some of them!
Kazuo has a serious complex with his height!
Komari really needs to learn to forgive herself for something that wasn't even her fault!
Nakano has to stop wanting to impress a bunch of snobs across the ocean!
Rindo needs a little love and learns that she doesn't have to be strong all the time! (She gives me a vibe of Tiny Tim from A Christmas Carol mixed with Katawa Shoujo)
Takahiro urgently needs intervention and forced admission to AA!
Hitoshi seems to be the embodiment of the generic guy!
Kohaku seems to be trying to escape the culture itself!
Miko and Mai need to mature and learn that their actions have consequences!
It is at least worrying that the least emotionally unstable people in this community are two nymphomaniac priestesses, a farmer with almost no personality and a saleswoman who is basically the idealized image of the waifu!
I don't hate any of them! Each is unique in its own way and we all have our own internal battles to fight! I just wish that at some point, we could help these foxes to overcome their problems!
