Yuki's Vacation

Yuki's Vacation is a 2D sidescroller for Microsoft Windows released by Ska Software in 2002.

Story
Yuki, a vampire ninja, was trying to have a nice vacation in her favorite vampire nightclub when suddenly beset by thousands of ninjas. As well as Yuki and her biddies, many civilians were present as well (though 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. Yuki decided to kill the ninjas that were ruining her vacation, and maybe feed off some civilians for the special powers she would get.
