Bismarck is a shipgirl from Azur Lane representing the German battleship, serving as the leader of the Iron Blood faction. She has long golden hair and wears black attire, contrasting her sister Tirpitz's short silver hair and white attire. Though she appears cold and unapproachable, embodying German stereotypes, she is actually very introverted and friendly. She shows a maternal side, such as taking care of Javelin and Ayanami on their way to school in official comics. In gameplay, she appears as a boss in event areas, with speculation of survival hinted by items like 'Proof of Promise' with U-556.
