Katou Kazue, the incredible mangaka of the incredible Space Traveler Robo and Usakichi, has a new series out named Ao no Exorcist. It has lots of awesome demons. DEMONS. This is so cool on so many levels. I loved Robo and Usakichi and I loved the one shot this new series is based on.
AAAAAAH SO EXCITED.
EDIT: AND IT'S BEEN SCANLATED. THIS GETS BETTER AND BETTER.
