Episode Description:
Now recognized as the ace pilot of Sidonia, Nagate Tanikaze is sent by headquarters to the military academy, in order to make a demonstration of his skills on the newest Garde virtual training console for the students. Meanwhile, Norio Kunato and Mozuku Kunato decide to explore the abandoned research lab of Ochiai and their bodies are invaded by parasites. Now under Ochiai's control, Norio and Mozuku visit the ERD and put the body of Numi Tahiro under control of a parasite as well. When Nagate later arrives at the ERD to visit Placental Shizuka, he learns that she was moved somewhere else. Depressed upon her disappearance, Nagate turns to Norio for answers, but to avail. Nagate hears from Yuhata Midorikawa that Placental Shizuka is under custody for research and that he must not see her again. Some time later, Gauna 549 approaches Sidonia and Nagate joins the sortie against it, piloting the Tsugumori Custom. However, Nagate and the other Garde pilots fail to break through the upgraded placenta of Gauna 549 until a huge Gauna-like creature appears to assist them. With Norio acting as its pilot, the creature introduces itself as Tsumugi Shiraui.
