I just recently discovered this manga. Don't let the title fool you, she ain't a Disney princess. Hime's like the daughter of the devil or something. Anyway she and her siblings are fighting over succession. And there's a bunch of horror film monsters in it. Like the werewolves and vampires and swampthings.

Other characters include Flandre the token loli robot maid who can only say "Fuga." There's Hiro, Hime's blood servant. There's Riza a half werewolf. And Reira, a vampire; Sherwood, Hime's little sister, and Fransisca, Sherwood's servant and Flandre's "older sister."

Oh and did I mention at one point Hime dual wields chainsaws.
