From Reject to God-Slayer

Arthur, a butcher trained by Uther, seeks family, saves Vivian, and learns he is Duke Richard's discarded son. Low-profile, exposed when a top knight kneels. When fallen knight Zalrok kidnaps his mother for an abyss rite, Duke Richard dies saving her. Enraged, Arthur masters God-Slayer Arts, rises to God of War, restoring Lionheart.
