This is an abstract art music video, not a piece of narrative fiction, so don't be expecting ninja vampires going to high school and fighting crime. That MAL makes you rate "story" or "character" is a bit silly, since that's not the point here. The characters and setting are an excuse for beautiful pictures. I enjoyed this as a twenty minute piece of visual art set to lush orchestration. The premise is an amorous dream shared by two Arabian nobles, and every image bleeds together quite organically into the next. There is no special meaning or message to discern. It is to be enjoyed for what it is. This is the sort of thing you'll love if you're in a dreamlike state, sober or otherwise. Or if you're an art student. This was designed for a visual art audience, not a typical anime audience, so be mindful of that before you watch.
Amano (Final Fantasy, Vampire Hunter D) is able to express a great deal with very simple lines, and his use of colour is dazzling. A similar project (but slightly more narrative) is Angel's Egg, which I'd recommend to anyone who enjoyed the style of art and the concept, but would appreciate a bit more of a story.
