Hey, good news! There's a manga that's going to start before the anime airing. You can read chapter 1 at
GanGanOnline.
Hell, if you don't understand Japanese (like me!), you might as well read it anyway. Art is much better than the mag scan posts earlier. Too bad the official website kinda spoiled part of the story, but hell Furyune looks
, Kurein/Kurin doesn't look half bad either.
