After Being Redeemed, All That's Left Is Revenge.

Everyone said that Professor Raven was a mage with a very good temper. Only he knew that he had been dormant in this academy called "Veritas" for fifteen years, sharpening his sword every day. Fifteen years ago, a bizarre fire burned down Thorne Manor and pushed the young man into an abyss of destruction. Fifteen years later, he stood in the square of the Royal Academy and used the earth magic that was despised by the world to drive that aloof hypocrite into the ground. He personally tore apart the lies of the hypocrite and sought justice for her. However, the person who would wait for him to come home would never come back again. ——After being redeemed, only revenge is left. After revenge, only endless desolation is left.
