Margot and Malga take out a raid of Tres España airships. Much to Segundo and Juana's surprise, Adéle has the main Musashi ship do an aerial back flip to attack the main Tres España ship from behind. The naval battle finally reaches a conclusion when Tori and Horizon join the fight assisted by the Aspida Philargia, and Tenzo and Mary activate the Excallibur Collbrande to seal the victory for the Musashi forces. After the battle, Mary starts living with Tenzo at the Musashi Academy, while Gin and Muneshige, stripped of their titles, decide to join the academy as well.
