Kuvira clearly has a pubic hair kink, which I'm fine with. I'm indifferent to pubic hair in these porn games but knowing that she gets off on it makes it fun. It's always nice to see someone doing something you know they enjoy. Like Ikki if she turns out to have an actual piss kink, and not just a fascination. It will be cooler if she gets off on it. Also, Toph having a foot fetish would be quite fitting since she sees through her feet.
Kuvira also seems to be a dominatrix. I wonder is she's somewhat of a sadomasochist or a switch. As in, is she interested in the MC because she wants to break him and he put up a challenge, or is she secretly turned on that she finally found a guy that can overpower her. So she takes out her sexual frustration on him by dominating him, but she's just aching for the next time he'll put her in her place.
I'm guessing the latter since this is a porn game with a male lead for a male audience. Chances are it will end with her submitting. No complaints on my end, I get off on "domination loss", a maledom overpowering a femdom.
