Saw a preview of that about a week or two ago, I think. Looks really interesting. Seems to be some kind of funky mix of Slice-Of-Life yuri with supernatural flavored surrealistic action. Is it by Studio Trigger by any chance? The animation style during action scenes kind of reminds me of them...
The Yuri also seems to be just my type, in the sense of being more 'cute' then outright 'sexy'. For instance, Valkyrie Drive could've been one of my favorite shows for sheer Yuri content, but its outright explicitness grew tiresome quickly, simply not leaving enough to the imagination. Something a little tamer can easily be far sexier, IMO.
