第 2 集: Nagate 以 Yamano 的形態與 Gauna 對抗，資深駕駛員則前往學院探訪。

Nagate's fellow pilot Eiko Yamano is killed and absorbed by the Gauna. Nagate regains consciousness and he fights the Gauna that has now taken the shape of Yamano, despite being ordered not to since the Heavy Mass Cannon was fired from Sidonia to drive it away. Nagate skirmishes with the Gauna but having no weapons that are able to eliminate it, Nagate retreats. The shot hits the target and the Gauna is knocked back and away from Sidonia while the remaining cadets return safely home. A funeral is held for Eiko and the high command officially announces that once again, Sidonia is at war against the Gauna. Three days later, Nagate is still disturbed with what happened and barely manages to sleep or eat properly. Even though it has only been three days, his bones have healed, but he is forced to remain wearing the casts. Meanwhile, the four highest ranking veteran pilots, led by Mochikuni Akai, pay a visit to the academy. Word gets out to the cadets, and Kunato and his friends assume they are there to see him, but are shocked when Akai completely ignores them. Instead, Akai approaches Nagate, infuriating Kunato.
