Ortho successfully infiltrates Malleus’ domain from the outside, he is attacked by Malleus, but successfully escapes with the analysis data he came to collect.
STYX deduces that they destroying Malleus’ domain could damage the minds of the people inside of it, so they decide to make dream-based contact with those inside and convince them to confront Malleus from inside the realm, instead.
In Idia’s dream human-Ortho is still alive and has enrolled at NRC’s rival school, Royal Sword Academy.
Idia attends an opening ceremony as his first day as Housewarden where nothing unusual occurs, which he describes as the ideal scenario.
Robot-Ortho makes contact with him from STYX, introducing himself as the autonomous AI that Idia created, but Idia does not remember him.
Robot-Ortho tells him to wake up and Idia’s dream threatens to collapse as Idia begins to remember. Dream-Ortho calls the robot-Ortho an imposter and appears in Idia’s bedroom to drag him down into darkness and a deeper sleep.
Idia reawakens on his first day as Housewarden and robot-Ortho forces his way into the dream to rescue him, but robot-Otho’s existence means that the dream cannot have a happy ending, so it begins to collapse due to the paradox.
Idia is dragged by the darkness into the abyss, which has taken the form of the Underworld, where he is welcomed by the dream-phantom version of his dead brother.
Idia refuses to believe what is happening but dream-Phantom-Ortho assures him that what happened to him is not Idia’s fault, saying he needs to stop blaming himself. Idia remembers, and says he needs to go to help robot-Ortho.
Dream-Phantom-Ortho refuses to let him leave, as the ruler of the Underworld, and Idia envisions himself as the strongest possible version of himself, which manifests as his overblot form.
Idia escapes back into his earlier dream, which has restarted again, but this time he remembers. He says that his brother would never go to Royal Sword academy and that his only little brothers are robot-Ortho at NRC and Phantom Ortho of the Underworld, sand that what counts as a happy ending is for him to decide.
After robot-Ortho explains the situation Idia reacts with shock that he as an innocent bystander has suffered the fate of his mother going through his computer, which she needed to do in order to build new gear for robot-Ortho, and Idia swears revenge on Malleus for the slight.
