In my humble gaming experience regarding the Kitsune characters:
Kiyoko: I like her, the impregnation fetish does it for me, tend to keep her in the necklace until she has 9 tails since outside pregnancy takes way too fucking long compared to the astral realm lol.
Kinu: Farmer one 100%, she isn't a bitch towards us and she doesn't marries an edgelord self insert Kirito.
Kohaku: Adorable demure merchant gal that sometimes sells cool shit!
Mai/Miko: A good roll in the hay, any more than that I tend to skip text lol.
Kuroka: Fun tease that has nice sex scenes and is never too haughty to us, good one!
Komari: Wish i could bang the shortstack gilf, oh well at least she isn't a pain like her edgelord spawn.
Rindo: Abit cringey, but i'd be lying if i said i don't have a thing for love-starved characters so she does get me going.
Nakano/Takahiro: Cringe Edgelord and Cringe Alcoholic, smack them both and never look back/have further interactions with them (is not like i'm gonna become a Kitsune to need Kirito-wannabe here anyway, the bonuses are crap lol!)
Everyone else: whatever/don't care.
TLDR: The kitsune are an ok lay, i just skip their weeb shit, get Kiyoko out of the realm and add her to my party roster as i keep on cruising, only looking back to them foxes for an ocassional fuck.
