Well, they MIGHT be. I mean, it's sort of -- weird. XD; Makubex at one point watches the two of them and notes that their "bond" may be what saves Mugenjou. Also, the reason they've undertaken this current job is that they've hired each other; Himiko has been kidnapped (we're like THIS CLOSE to finding out the full story about what the "Voodoo Children" are and their signifigance), and Ginji's mother is supposedly in Babylon City. So.

And THEN there's Ban's comment about how his father would only be fighting them if his mother were up there, which prompts Ginji going GEE BAN-CHAN YOUR MOM'S IN BABYLON CITY TOO? :O and. Yeah. XD

I'd still completely ship them, but I might cry a little while I did. XD
