Maybe instead of a traditional Western zombie, we can have a jiang-shi instead. Jiang-shi are basically Chinese zombies, but they also have attributes similar to vampires in the way they suck blood from their victims. Don't know what a jiang-shi looks like? Just look at Hsien-Ko/Lei-Lei from the Darkstalkers series. Before anyone brings up the matter of a Chinese zombie being in Japan, consider Meiling, a Chinese demon/youkai, first.
Aw, I was just about to call Hsien-Ko too! Alternatively, let's call in the original zombi (is it Hindu or Carib?)!
I don't see why Chinese mythology aspects, or most of its ideals for that matter, would be strange in Japan or Korea at all (see Dragonball series, unlucky #4, Buddhism (albeit with notable differences), script (Japan/China), grammar rules (Korea/Japan)).
On the topic of Darkstalkers, a
loli Bishamon-esque character COULD fit with the graves/spirits idea of 10D.
