Kaibutsu Oujo

Werewolves, demons, monsters, vampires. All these ferocious creatures are afraid of the same thing: the beautiful Princess Hime, an awesome warrior who fights off the forces off evil with a chainsaw and a smile. Not only does she look great in a tiara, she has magical powers that allow her to raise the dead. She's a girl on a mission, and with the help of her undead servant and a supercute robot, there's no creature of darkness she can't take down!
