A gigantic aircraft carrier from Girls und Panzer owned by the Ooarai school. It is based on the real life Zuikaku, but ten times bigger, stated to be over 2,500 meters long. The vessel served as the location of the school and a mobile stadium for the Sensha-do tournament.
Ironically, it is shown to be smaller than the Girls und Panzer Ark Royal, despite the real-world Zuikaku being larger than the real-world Ark Royal.
