The Japanese Ministry of Defense has an anti-paranormal special forces group called the Paranormal Disaster Countermeasure Headquarters. They're the ones responsible to protect Japanese soil and its people from supernatural and paranormal events. However, things didn't go so well in one of their missions, which leads to intervention by the Ministry of Enviroment's Supernatural Disaster Countermeasures Division after the PDCH has sustained large numbers of casualties battling demons.
The anime re-imagining of the original live-action series follows the Winchester brothers Sam and Dean as they hunt creatures and other supernatural phenomena across the American landscape. The anime will be a 22-episode season that will cover the storyline of the live-action version's first two seasons. The anime project will not only remake the best episodes from the live-action version, but also depict original episodes not seen in the live-action version. Those original episodes will include prologues of the Winchester brothers' childhood, anime-only enemies, and episodes featuring secondary characters from the live-action version.
