The story is set in a private high school that brings together "saviors," youths with awakened memories from past lives. Some of them are Shirogane who fight enemies with weapons and techniques gleaned from the Puraana powers from their own bodies. Others are Kuroma who wipe out enemies, with magic to manipulate the Maana powers that surpass physics. A boy named Moroha Haimura enrolls in this school. He is the first person in history with past lives of both Shirogane and Kuroma.
