World Break: Aria of Curse for a Holy Swordsman

The story is set in a private high school centered around the idea of "Saviors"-people who have awakened memories of their past lives. A young boy named Moroha Haimura enrolls in this school, where two distinct groups exist: the Saviors, who battle enemies using weapons and skills drawn from the Puraana powers within their bodies, and the Kuroma, who eliminate threats through magic that harnesses Maana powers beyond physical laws. Moroha is unique, as he is the first to possess past lives of both a Shirogane and a Kuroma.
