I might watch that just to see the two Syaorans. And vampire Fai. :3 Was Kurogane's past animated during any part of the anime? If they only got up to Tokyo, then I guess they haven't gotten to Fai's past.

NYANKO-SENSEI!!! Natsume wouldn't part with Nyanko-sensei. I'm sure he'd rather keep his powers (after a lot of brooding and reflecting of course, hehe). I'd love to see Natsume enter Yuuko's shop though. :3

Watanuki's so good at giving names...would be nice to see that tied with Natsume somehow. XDD These two series can be crossed so easily.
