The Demon World: a place where it's good to be bad.

Werewolves, zombies, and even the Abominable Snowman fight day and night for the title of Territory Boss. The vampire Staz, however, finds the whole thing to be a serious pain. He spends his time watching anime, playing video games, and daydreaming about going to the Human World. That all changes when he meets Fuyumi, a human girl who instantly wins Staz's heart, and who then loses her life to a man-eating plant. Refusing to give up on the girl of his dreams, Staz travels across the Demon and Human Worlds in search of a way to bring Fuyumi back to life by any bloody means necessary.
