Childhood's End.With the Deucalion crashed, Yuki and Inko attempt to escort Asseylum to the Landing Castle's Aldnoah Drive themselves. Meanwhile, Inaho takes it upon himself to hold off Saazbaum, who reveals that his Dioscuria now possesses all of the abilities of the Kataphrakts Inaho had previously fought. Meanwhile, Slaine follows the Deucalion back to the Landing Castle, and boards the Tharsis, hoping to at least be able to fight with auxiliary power. However, he finds out to his surprise that he has the ability to activate Aldnoah Drives as well. As Inaho and Saazbaum fight, Saazbaum initially has the upper hand due to the technological superiority of his Dioscuria in comparison with Inaho's Sleipnir, but Inaho uses everything he has learned from previous battles with Vers Kataphrakts to exploit Dioscuria's weaknesses, severely damaging it. However, before he can finish off Saazbaum, Slaine tackles Inaho's Kataphrakt with Tharsis. Right when Asseylum manages to reach the core and shut it down, Inaho and Slaine's Kataphrakts crash through the wall of the chamber holding the Aldnoah Drive. As Asseylum goes to assist Inaho, she is shot and apparently killed by Saazbaum, who thanks Slaine for saving his life. Slaine, in a fit of rage, fires at Saazbaum with his pistol until his magazine is emptied, which mortally wounds Saazbaum. Inaho, injured from the crash, crawls his way to Asseylum's body. As Inaho remembers various memories of his time spent with Asseylum, he realises that he genuinely loves her. However, Slaine stops him and holds him at gunpoint. The two recognise each other's voices from the battle with Femieanne, with Slaine referring to Inaho as "Orange" (due to Inaho's orange-coloured KG-6 Sleipnir) and Inaho referring to Slaine as "Bat" (due to Slaine's bat-like Sky Carrier). Inaho attempts to draw his own gun but is shot by Slaine in the head. Afterwards, it is said that after the shutdown of Saazbaum's Landing Castle, the attack on the UFE headquarters ended in a complete UFE victory, although at a high cost. Asseylum's whereabouts are also stated to be currently unknown. In the final scene, an unknown Kataphrakt is seen to be flying away from the wreckage of the battle.
