"Resound Into the Azure Sky"

Confronted by soldiers from the 9th Division, Aisha suffers serious injury in front of a frightened Noël. Meanwhile, Filicia takes Col. Hopkins hostage and orders his forces to leave the fortress as they barricade themselves inside. Col. Hopkins divulges his intention to use Aisha to instigate war, in addition to revealing his connection with Noël who once worked with him in reconstructing an ancient bioweapons technology that resulted in the deaths of many people. After being locked up in the distillery, he manages to make his escape in secret. While on tower patrol, Kanata hears a faint and distant signal for cease-fire prompting her to tell the others. Naomi with the support of the townspeople try to convince the 9th Division of the signal for cease-fire but are arrested by Col. Hopkins. Out of options and with an injured Aisha in tow, the girls decide to use the restored Takemikazuchi to stop the 9th Division and prevent all-out war between the nations. A battle between the 1121st Platoon and the 9th Division ensues as Yumina narrates the Roman version of the Fire Maidens' tale. Upon reaching the field between the approaching Roman and Helvetian armies, Kanata issues the cease-fire signal but is ignored. She then plays Amazing Grace, which temporarily stalled both forces. Before any more hostilities restart as the song ended, Princess Rio Kazumiya Arkadia appears, accompanied by the Helvetian Royal Guard and orders both sides to stop, carrying an official document declaring that the war has been officially ended, which is received in celebration. Following the time of peace, Rio rejoins the 1121st Platoon, as a reward from her fiance, the Roman Emperor, in return for stopping the war.
