Ilse Von Tirpitz is inspired by the Azur Lane Character and its real counterpart, the KMS Tirpitz.
Ilse Von Tirpitz: 'The Lonely Queen of the North'. That was the nickname by which she was known, even if she was 'only' a Duchess. She barely showed herself at court, and she was considered so cold and unapproachable that no one dared to cross ways with her, especially given her reputation and her weapons mastery. She didn't like coming down at the capital, and much preferred staying at her lonely estate up north, managing and defending her territory.
Today, it was the 21st birthday of the Crown Prince. This meant that he was officially becoming an adult, and so, they held a great party at the royal palace, at which every noble had to attend, even the Duchess, that was already there, between all the nobles.
