Casey (Spider girl) and Ben (the human)
You can read the short comic of how they meet here if interested. Casey is a spider person. Much like a vampire, except with very spider-y qualities! She has to wrap people up in webs and drink their insides Mmmm! She doesn't like it though. She just HAS to. Ben is her best friend whom she almost was going to eat, but is very glad she didn't! (For later, she marries him!)
