Episode Title:
Oblivion.
Episode Description:
Eiko Yamano is killed and absorbed by Gauna 487, which soon disturbingly takes on the appearance of Eiko. Nagate regains consciousness and furiously launches a solo assault on Gauna 487 against orders, as the Heavy Mass Cannon is fired from Sidonia to drive it off. Lacking the spear-like weapon called the Kabizashi necessary to destroy Gauna 487, the surviving cadets retreat to Sidonia, while the Heavy Mass Cannon blasts Gauna 487 away. As a funeral is held for Eiko, a war with the Gauna is officially declared. Three days later, Izana takes Nagate to Eiko's memorial, but Nagate ends up feeling traumatized and uneasy due to what he saw at the mining expedition. However, his injuries have healed astonishingly fast, despite being forced to remain wearing his orthopedic cast during his recovery period. Meanwhile, the four highest ranking veteran pilots, led by Mochikuni Akai, pay a visit to the academy. They approach a confused Nagate, while ignoring Norio in their path. Nagate is also stopped by Yuhata Midorikawa, who offers to be his friend.
