Hannah was Alois's demon maid and servant. In the first episode of the second season, Hannah's left eye was gouged out by Alois on the account that she stared at him directly. She was quiet and seemed to be very fearful of Alois as he often harmed and humiliated her. She was very skilled with combat and able to pull weapons out of nowhere and she was the sheath of the legendary sword Lævateinn. Despite Alois's abusive treatment of her, Hannah was deeply loyal to Alois and cared for him. Near the end of the second season, Hannah revealed that she previously formed a contract with Alois's younger brother Luka (who she had grown to love during their short time together) and upon discovering that, Alois accepted Hannah's love and stopped trying to receive acknowledgement from Claude. Once Sebastian's duel with Claude was over, Hannah approached Claude's dead body and proclaimed that Alois and Luka would live happily in the afterlife with her and Claude.
