‘Ga-Rei Zero’

The Japanese Ministry of Defense has an anti-paranormal special forces group called the Supernatural Disaster Prevention Agency. 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 Environment’s Supernatural Disaster Countermeasures Division after the SDPA has sustained large numbers of casualties battling demons.
