Ekijin (the God of Pestilence) Syndrome is a fatal illness that generates supernatural powers in its victims. The cause is unknown and there is no cure, only treatment to alleviate symptoms. Anyone, including yourself, your family, or your friends, can be struck down and transformed into the very embodiment of death. However, there are brave souls who resist and combat this hopeless affliction - the Ekijin Corps, a special division of the Treatment Execution Organization.
Despite being stricken with the disease themselves, members of this unit employ their newfound abilities as weapons and risk their lives to rescue others. They fight until the bitter end in order to protect the people in their care and overcome the disease that ultimately awaits them. These doctors are true warriors, displaying immense courage and determination in the face of overwhelming odds.
