Kazuki, Maya, Kenji, and Canon, all accompanied by Kyouhei, charge straight towards the entrance of the core in order to rescue Soushi, who is revealed to be inside the core. During the operation, Tsubaki is experiencing the death process to complete the learning process for the Festums to understand life and death. Moreover, she will need to return to the core to complete this process. Kenji maps out a plan of attack, Canon confirms the battle formations, and Maya reminds that all pilots will return to the island alive. Soushi is being controlled by Idun, who uses the Siegfried System to exploit the weaknesses of the pilots, that being to break their battle formation. The four pilots all reunite and defeat Idun together. Meanwhile, Tsubaki struggles with her emotions at leaving to synchronize with the island core. Kazuki, with the help of Akane, manages to rescue Soushi, bearing the assimilation. As the Meir begins to make its way to the atmosphere, Maya snipes at it, preventing it from spreading all over the world. Tsubaki has become one with island, as she dissolves into thin air. Idun, barely alive in the Fafner Mark Nicht, hinders Kazuki and Soushi from leaving the battlefield, but Koyo is able to save the two. On their way to the island, Soushi vanishes because of his near assimilated state. (Source: Wikipedia)
