Buffy the Vampire Slayer — Dark Horse Comics
Issue: #36
As they try to deduce her whereabouts, Buffy turns Sunnydale (and a whole lot of vampires) upside-down in her search. Spike suspects that Dawn's disappearance has something to do with a former Slayer turned vampire, the deadly Yuki Makumura. It looks like this Vampire Slayer must go up against a Slayer Vampire. Could things get any worse? Don't ask!
