During my playtrough, I was happy to see Kinu fall in love with a farmer boy. Not everything has to be incest.
Like I give a shit about incest or who the fuck she ends up with.
The problem here was that they didn't give Kinu quite enough time to be the little shining darling she could be, you just get some time with her until you bring the orb to the Tree of Utter Cunts and then it is arbitrarily decided that the next time you see your little daughter, she's now an utter bitch to either parent of hers and you missed out on most of her growth.
You could have had some hijinks with little Kinu messing around in the village, playing badminton with the Senko rip-off, slam poetry with the one kitsune whose half is burnt, spike the local drunk's sake with laxatives and then gradually have her grow up in a couple of weeks.
Couldn't even have accidental wholesomeness in this shit, could we?
