Despite being from two totally different worlds, I see these two have plenty in common. Both orphans, both unable to find their place in the eras they each inhabit. In my latest fanfic, she comes to his era in a time machine and learns rather quickly that his friends are nice people.

Very interesting concept. I like the idea of pairing Hiei (who has three eyes) and Leela (who has one eye); kinda weird though because they're from TOTALLY different worlds n' all, but it's still a cool idea. They kind of even each other out. (a total of four eyes = two pairs) Keep it up ^^.
