7.70 24 minutes 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.
