Certainly one of the most odd volumes of manga I’ve read as of late, I recently reviewed volume one of Demon Sacred for AnimeNewsNetwork.
My thoughts – this is a pretty silly story. Then again I’m not sure if you could really present the premise any better – demons in the form of unicorns from another dimension trapped by fangirls in the bodies of their pop-sensation idols – that about sums it up. I wasn’t especially intrigued or engaged in the story at all, it came off as too silly for me to take seriously while not silly enough to be intentionally funny. I’d very much recommend the creator’s more engaging Jyu-Oh-Sei over this which takes the twins fighting-against-odds story much more dramatically. That is of course unless you’re looking for silly, then step right up to Demon Sacred.
