I only saw one movie that appeared to just be titled "Vampire Hunter D."

There were some things that were a little confusing, like there should
have been some movie before this one.  (spoiler :) The one I saw
involved a girl named Doris, who had bitten by a lecherous Count Lee,
and who had a younger brother, Dan.  D comes to save the day, the girl
falls in love with him, he defeats Count Lee, and rides off, with the
implication that he is the son of Dracula. 

My question is about the thing in his hand.  The only thing that I think
it could be is a parasyte, as mentioned in the manga story, in
Mixxzine.  That parasyte go stuck for some reason in a boy named Shin's
hand, this seems to be the case with D.  Is that what it is?  Or am I
totally of base?  The first time it talked was when D was drawing his
sword, so I thought it _was_ the sword, which wouldn't have been too
unusual.
