The narrative revolves around a private high school where individuals known as "saviors" exist, characterized by their ability to recall memories from previous lives. In this story, we follow Moroha Haimura, a young boy who enrolls at the school. At the institution, there are two distinct groups: Saviors, who engage in combat against foes using techniques and weapons derived from Puraana powers within their bodies, and Kuroma, who eliminate enemies through manipulation of Maana powers beyond physical limitations. Notably, Moroha Haimura is unique as he possesses past lives associated with both Shirogane and Kuroma.
