Yuki, a vampire ninja, was trying to have a nice vacation in her favorite vampire nightclub when suddenly thousands of ninjas started attacking her and her vampire buddys. Lots of civilians were there too (the vampires would've harassed and killed them by the end of the night anyway). Yuki realized that the ninjas were created by The Horrible, which makes ninjas and isn't a very hard last guy. Yuki decided to kill the some two thousand ninjas that were ruining her vacation, and maybe feed off some civilians for the special powers she would get.
