This prequel adaptation of the original manga by Hajime Segawa will be officially licensed and distributed in the United States, as it will come out in DVD in 2011 with all 12 episodes..The story revolves around Kagura and Yomi, two highschool girls that are members of the special force called the Paranormal Disaster Countermeasure Headquarters (PDCH), an organization that responds directly to Japan's Ministry of Defense and it deals with all paranormal fenomena and disasters.
Can't wait to see when the actual Ga-rei story gets made into an anime too!!
Funimation will also stream the first two episodes in Youtube, just as it's been doing with Soul Eater lately.
