10화: 나게이트가 금지된 연구를 조사하고 거대한 가우나 위협에 대해 시험되지 않은 무기를 조종합니다.

Nagate, Izana and Yuhata take a trip together to a little-known inn, and Nagate is astonished when he recognizes Captain Kobayashi as the place's innkeeper. Yuhata reveals that she obtained information about Ochiai's forbidden research that led to his condemnation, and takes the others to investigate. The trio end up trapped inside the installation, and, while attempting to find a way out, take an elevator to a highly classified area, including a doorway to MSCF 5, a high-security isolation ward. There, they are surrounded and sedated by security. Nagate wakes up by himself and meets Yure, who reveals that the legends of Ochiai creating a Gauna/Human hybrid being are indeed true, and is shown the corpse of the hybrid, which scientists have been able to use to manufacture artificial kabi with which to destroy Gauna, thus reducing reliance on the limited number of Kabizahi. Yure continues to explain that both the Guana-Human hybrid and the Kabizashi emit a radiation which attracts the Gauna to the Sidonia. Captain Kobayashi appears and reveals that Nagate will be the test pilot for the new weapons system. Meanwhile, Kunato also reads about Ochiai's experiments and comes across a mysterious door, access to which is forbidden even to the members of his family. Nagate is sent back to the inn with Izana and Yuhata, who awaken with no memories of what happened; he feigns ignorance as well. Some time later, a colonization ship carrying pacifists, who claim that the Gauna only attack because of the Kabizashi and will not attack unarmed humans, departs to settle on a nearby planet. Nagate is brought to Toha Heavy Industries, where both the new weapon, a long-ranged projectile launcher, and a new Guardian propulsion system are being developed. It is revealed that the simulator they are developing to make tests on both prototypes is the same one he used to train with his grandfather. When the Sidonia discovers Gauna 541 moving to intercept the colonization ship, Nagate offers to use the prototypes to go after the Gauna and defend the ship, a supposedly impossible feat as the equipment does not have automatic stabilization and is completely untested. However, Nagate states that he has used it in his grandfather's old simulator, and Kobayashi approves his request to launch the sortie. Despite missing his first shot and losing control of his frame from the massive recoil, Nagate successfully re-stabilizes and destroys the Gauna with a second shot, moments before it reaches the colonization ship. After the mission, Nagate is called to the ERD and cheers up when Placenta Shizuka uses a pen to write his name, before he is summoned by the Captain. En route to the briefing, Nagate meets Izana, who tells him that she has just been instated as a pilot, and, knowing the low survival rates, especially among new pilots, is distressed as she believes her time with Nagate is soon to end. Nagate attempts to reason with Izana, who, upset upon guessing that he was visiting Placenta Shizuka again, runs away, nearly falling to her death after slipping, although he saves her just in time. Meanwhile at the command center, a massive Gauna pod, 8,000 times the size of the Sidonia, is detected rapidly approaching the ship. (Source: Wiki)
