The most amazing thing about this vampire is how un-amazing it is. Not that it doesn't have powers or anything like that. But that the Kyuuketsuki is almost exactly like the common European Vampire.
They are often depicted with white or red hair and red glowing eyes. They have fangs like other vampires, but can also have a mouth full of sharp teeth. Sometimes instead of turning into bats they grow large bat like wings.

Game wise they really do not differ all that much from other vampires.
Getting into the Anime or Manga versions they can have all sorts of strange powers. Such as using their hair to fly, or having a demon possessed body part, to even using blood as a tentacle to grab on to things.
I think to give them variety I would grant them telekinetic powers.
