Vampires Charles J. Chrishunds (Charley) and Johnny Rayflo have a strange relationship. Charley is a cyborg and a vampire hunter for the Vatican, while his master Johnny enjoys a playboy lifestyle. While fighting crimes involving vampires, Charley struggles to control his lust for blood and for Johnny, while Johnny delights in seducing his servant and attempts to deal with issues from his own past. Johnny cares about Charley (also known as Cherry and Chris), and these feelings don't seem to be one-sided.
