In a country where white mages are worshipped and black magic is feared, a despised black mage is betrayed by the saint she once trusted and condemned for crimes she never knew her magic was used for. After returning to the past, she vows to expose the truth, protect the kingdom with black magic, and survive her second life. But this time, the magic once hated as monstrous may become a force of justice and she may finally be loved by the people she never expected.
