What about Kunimitsu?

I've no problem in seeing them as a romantic couple. There was a theory at some point that Kunimitsu going megalomaniac had something to do with Devil tampering with her mind (didn't she cooperate with Kazuya at some point, or have I imagined it all?). So if Yoshi kills Jin/Devil in Tekken 6 (which would be, if you want my opinion, a real refreshing wind in the dusty and moldy Kazama/Mishima world of Tekken), Kuni might return to her old self.

It would be nice to know, however, how Yoshi would ever manage to tame Kuni's rather fiery temperament... :dontgetit
