At first he had taken her original name IJN Kii before renaming her after a good friend of his who went missing. After creating the necessary parts to the ship he then had the construction machine finish her before opening her pod. After explaining things to her she joined his group. She has the habit of calling him Dad, Meine Liebe, and ləv.
