Aristide

Blood-Mad Duke”: Aristide earned this title due to his ruthless combat skills and rumored bloodlust, especially in battles against monsters. But beneath that savage exterior lies a man capable of deep loyalty and subtle tenderness. Protector and partner: He saves Melphiera from a monster attack early in the series, sparking a bond that blends danger, romance, and mutual understanding. Their dynamic is a mix of gothic intensity and romantic comedy. Possibly supernatural: His yellow eyes and unusual aura suggest he may not be entirely human, or at least carries a cursed or enhanced lineage. The anime teases this but hasn’t fully revealed his origins yet.
