So Kiyoko is abusive, there are very little signs pointing to that in-game, and the Champ can do literally nothing about it. Perfect game design, I see nothing wrong with that.
For real though, I don't understand anything about what's going on though. Kiyoko makes food for the Champ every time they visit her but not her own children? None of your children speak to you about the abuse going on, even in passing? Kinu is just fine with this happening despite her being able to run away to the Champ anytime this kind of shit happens? TOBS knows it's okay to get help with abuse, right? This can still be a story about a woman becoming her own person even if she gets just a little help from her father. Suffering on your own ISN'T a good thing, TOBS.
I don't know why he's obsessed with making every Kitsune a broken piece of shit while also putting them on pedestal. Does he think that makes them deep or something? Because it doesn't.
I really like some the points here. The abuse is subtly suggested in the Kinu training scenes and when you ask Kiyoko about her. Kiyoko never has anything nice to say about young Kinu, it's all that strained double speak that TOBS is infatuated with. But the fact that you pick up on some of it, and you get to see the Kinu perspective scenes, mean that you the audience can learn about it and, as you say, can do nothing about it.
The main thing though, is this shows what TOBS sees these characters as and his vision in its purist form. Kinu is the important one who must go through great hardship to earn her importance. Kiyoko and her traditional ways are something to rebel against and is two-faced and shallow. Champ is a no-show in Kinu's life, just some distant figure she can never look to for help, you're not her parent, your Kiyoko's sperm donor. And why? Because TOBS thinks her suffering through all this will make her stronger, that she'll learn from it, otherwise her significance won't be justified. When in reality she'd probably suffer from Battered Woman's Syndrome and be a far too grim a story for this game.
And all of this...
Has nothing to do with Kassyria, Savarra, Corruption of Champions, or reality as a whole.
It's just his shitty fan-fiction, ripped off from princess maker, that Savin let him insert into his game, which was a rip off of Fen's game.
The Matroska doll of bad porn games.
Or as someone better with memes might say. CoC2 writing is like an onion, it has layers. And all of them make you want to cry.
