Episode Title:Choice.Episode Description:After killing the members of the Akai squad, Gauna 487 proceeds on a collision course towards Sidonia, prompting Kobayashi to order an emergency evasive maneuver by accelerating diagonally. This causes massive casualties in the spaceship's residential district, despite the efforts of the citizens to brace themselves. As Gauna 487 turns back to target the spaceship again, Nagate, Shizuka, Norio and En Honoka are ordered to salvage the Kabizashi used by the Akai squad. Just as the Kabizashi is retrieved, Gauna 487 turns its attention to them and fires a Gauna Particle Cannon, a red laser beam, that incapacitates all their Gardes except for Nagate's Tsugumori. Shizuka's Garde goes haywire, which forces her to eject from her Garde. Nagate grabs the Kabizashi and solely destroys Gauna 487, disobeying orders to tow Norio and En back to Sidonia. As the others celebrate Nagate's feat, he selfishly leaves in search for Shizuka, despite being warned that he will undoubtedly pass the point of no return to the Sidonia.
