Could some kind person please give me a translation into ROMAJI of these
phrases, one of which I want to use as the title of a story:

"Vampires and Slayers" or "The Vampire and the Slayer"

My first approximation done purely from a dictionary is this:

"Kyuuketsuki to Shikeishikkonin"

tho I'm pretty sure it's going to be wrong. 'Shikeishikkonin' my dictionary
says means 'Executioner', which was the closest I could find, but is there
something closer? I expect my grammar is up the spout as well.

TIA
