As CGS adults retreat from Gjallarhorn's assault, they deploy Mikazuki and the other children as decoys. Left behind, the group gathers under Orga's leadership. Determined to resist, Orga initiates a specific plan to counterattack Gjallarhorn. This decision marks a turning point for the remaining students as they prepare to face the enemy forces directly, relying on their own strength rather than the fleeing adults. The narrative focuses on the strategic shift and the resolve of the children to stand their ground against the overwhelming military pressure.
