It's a Supernatural/Horror anime, but the craziness kind of overpowers the horror. The animation style takes some getting used to because of all the different camera angles, the fighting scenes are a little odd... It's some first-class mind****ery. But yeah, it's a really good anime, the characters are the perfect balance of odd and great, the different mysteries actually have you reeling for a couple of episodes, and in my opinion, it has the best special effects out of all animes. That and good openings, especially S2.
