Hime is a princess of monsters. Period. That's all you really need to know, really. Afterwards, all there is is around 30 minutes of nonstop bloodshed and people getting sliced in half, ect. This anime is just awesome. Just watching the first episode left me speechless.
What makes it so special, at least in my mind, is how they can incorporate a goth plot with random humor so well. We have the scapegoat, poor Hiro, who's constantly getting killed around every three episodes or so. But with Hime's extreme reviving powers, it really dosen't matter anymore. He can die as much as he want, which is funny in a wierd way. XD
