Kazuya is about the same he's always been but maybe a little better. I'm indifferent to him more or less.
Ruka is the one who's an annoying bitch and it's funny to see tomboyfags constantly crying about Kazuya ignoring her/not liking her when this bitch blackmailed him into dating her and doesn't give a shit about him.
Instead she's a selfish bitch who only thinks about herself and doesn't care about how he feels despite how much she claims to love him. This is what makes her all the more unlikeable and the tears of her fags will be glorious when shit inevitably goes down.
