Trying to remember a fic

I just remembered a fic I read a year or two ago, and I can't remember anything about it except this one chapter and the big twist of the chapter. If I'm remembering it correctly, there was some sort of vampire invasion and I believe the count from sesame Street was involved. There was a lot of buildup to who the leader of the vampires was, making it look like it was Alucard from Hellsing, but then it's revealed to be DIO from Jojo's Bizarre Adventure in the form of a 'it was me, DIO!' joke. Does anybody else remember this fic, or am I just remembering a very strange dream?
