After discovering Shizuka was one of the casualties during the battle, Nagate recounts the events and what ensued during the fight: Nine squads of frames (36 guards) are deployed to destroy Gauna 488 with Kunato's squad tasked to destroy the tail of the massive Gauna using explosives. Kunato, Shizuka, En and Nagate plant their explosives around the tail of the Gauna and prepare to detonate on Kunato's orders. Kunato however, activates a secure channel with Nagate and deliberately orders him to detonate the explosives too soon. This causes the Gauna to become aware of their plans and the other explosives are shaken loose due to the imbalanced explosion. All frames are then ordered to temporarily fall back and re group but Nagate loses confidence and is struck by the tail. As Nagate begins to fall unconscious, the Gauna almost kills him but Shizuka saves him at the expense of her own life. The remaining pilots do manage to destroy most of the Gauna but seven pilots are lost during the battle. En Honoka survives but is critically injured. In the present, Nagate has recovered from his injuries but is now greatly hated by the population as they believe his "failure" was the cause for the many deaths during the battle (due to the tail not being severed). Nagate takes some time away with Izana and he slowly regains his confidence in piloting the Tsugumori. Meanwhile, the captain orders the destruction of a planet, where the surviving Gauna from the previous battle have fled. With Yuhata instated as the new Executive Officer, the planet is destroyed successfully but Gauna 489, 490, & 491 appear from the planet's remains. The Captain orders Yuhata to assemble a squad (including Nagate) to intercept and destroy the Gauna. When more detailed images of the Gauna are shown, it is revealed, to everyone's shock, that the Gauna have taken the form of Guardians with the unit number 702, formerly the callsign of Shizuka.
