Azure Sky Plan Episode 12

After making contact with Mitsuhiro, the enemy core plots to win over the commander who seized Australia's habitable zone, and the commander is actually influenced by the core's words. On Tatsumiyajima, Miwa is once again attempting to communicate with Altair, but it isn't going well. Later, as the final battle draws near, a long-planned coming-of-age ceremony is held for Kazuki, Soushi, Maya, Kenji, Sakura, and Kouyou, in which Fumihiko grants them official status as Alvis personnel.
