Decisive Battle.As Placental Shizuka removes Nagate's space helmet and attempts to merge with him, Izana switches the systems of the Tsugumori Custom 2 to auxiliary power, allowing Nagate to deal a killing blow to the Crimson Hawk Moth. After Nagate releases Tsumugi from the spikes, the Samari squad equipped with the Hayakaze appears to wipe out the oncoming swarm of Gauna, retrieving Nagate and Tsumugi and effectively conquering the planet. Nagate is embarrassingly forced to carry the nude Placental Shizuka in his arms while cradling Tsumugi in his Tsugumori Custom 2 as he returns to Sidonia with the rest of the squad. As Nagate is decorated for his bravery, Lala Hiyama urges Kobayashi to stop using Nagate for political gain, but Kobayashi remarks that she understands the difficulty of sustaining a long war after a hero has fallen. Tsumugi later upsets Nagate when she dresses up like Shizuka, but he takes Izana and Tsumugi to a food stand to make up for his outburst. After visiting the hospital and the rice factory, Nagate leaves his medal of honor in the underground shelter where he was raised by Hiroki Saitō as a sign of gratitude before being deployed for his next mission.
