What does 'banpaia kyuuketsuki' means in English?

They both mean vampire. The difference is 'Banpaia' is the Japanese pronunciation of the English pronunciation of Vampire.

V's are pronounced as B's, and N's and M's have a similar sound to them. So Vam=Ban, Pi=Pai, and Re=A.

If you say it out loud it makes a lot more sense.

Kyuuketsuki is the Japanese Word for vampire. I wish I knew it's literal meaning, but I don't. Sorry!
