Looking back through the earlier chapters, it dawns upon me

Spoiler for Shapeshifting:

We've gotten a hell of a lot of evidence that the only reason that vampires in this setting look 'pretty' at all is a matter of vanity. It makes PERFECT sense that, if Tsukune has gone critical mass and gone over the edge into vampdom, he'd look like Zetman or something like that until he's gotten a grip again. I'm not only thinking of Alucard, of course, I'm also thinking of Kahlua.
