The scenery takes place in a private high school involving the concept of "saviors." They are known as people who possess awakened memories of their past lives. The story tells of a young boy named Moroha Haimura who comes to this private school. At the school, there are two types of people: Saviors, who fight enemies with weapons and techniques gleaned from the Puraana powers from their own bodies, and Kuroma, who wipe out enemies with magic to manipulate the Maana powers that surpass physics. Moroha Haimura is the first person with past lives of both Shirogane and Kuroma.

Students at this private academy battle monsters using the violent, awakened memories of their former lives. This fantasy adventure pits the heavy burden of past incarnations against the desperate need to protect a fragile present.
