Ah. See, I can understand the appeal. The “they hate/love” each other angle. And of course, Kuwabara’s love for Yukina. 

I don’t see them romantically involved at all, though. They seem to have a more of a sibling relationship. They argue, but they respect each other. It’s like my brother and cousin, who always used to pull each other’s hair and cry over the same toy, but in the end, they loved each other.

Though, who doesn’t love a little size difference? 😉 

In all seriousness, though, Hiei isn’t a good match for Kuwa, and vice versa. Kuwabara isn’t patient enough to deal with Hiei’s crap. And Hiei is too abrasive. Kuwabara is a classical hero, and he needs a classical Lady. Yukina is that lady.
