However, he lets Tomoka speak with Kuniko briefly before ending the conversation, telling her that he will pretend that the two girls' conversation never happened. Rena, Nao and the other prisoners plan something by bribing various guards or improvising various materials. Ryoko plans to do something about Kuniko and Mikuni's destinies with the former's execution. Wearing lipstick and her original colthes, Kuniko prepares for the execution. Suddenly, Kuniko cuts off the guards' weapons with nanowires from the lipstick and escapes with Tomoka on a hydrogen balloon the prisoners created, promising to come back for them one day. Ryoko is impressed by what Kuniko and the prisoners did, but she has the guards kill off all the prisoners. As Kuniko and Tomoka head home with a waiting Momoko, a solar eclipse occurs and Mikuni and her retainers play on the highway.

Ryoko decides to make Miiko the next vessel for Lord Hiruko. Kuniko returns with Momoko back to Duomo to think of their next step. After being welcomed back by the citizens, Kuniko goes to confront Nagiko about her role as first governor of Atlas. When she gets no answer, Kuniko has no choice but to banish her grandmother from Duomo. Before leaving, Nagiko informs her about Takehiko's disappearance after returning to the town. Miiko is forcibly turned into Hiruko's new vessel. Furukawa shares Kuniko his discovery that the artillery attacks came from a genetically modified plant called Daedalus. Ryoko also discovers this fact, but ignores the plant's threat as it will not be able to harm Atlas, but the same could not be said for Duomo and the rest living below. Kunihito makes his decision to leave the military. Mikuni pulls herself together and plans to attack Atlas to rescue Miiko. Kuniko and her team make their way to the forest to burn down Daedalus, but it retaliates against them.

As Miiko's personality fights against Hiruko to speak with Mikuni, Ryoko has security surround Mikuni. Sayoko arrives to take Miiko/Hiruko hostage and leaves Atlas together with Mikuni. Momoko tells Kuniko that Daedalus will one day overwhelm and create a forest full of its plants, due to the bomb shower. As Kuniko contemplates this alone, Takehiko attempts to kill her.

Kuniko, Kunihito and Momoko go after Mikuni, who is about to make herself successor of Atlas. Kunihito distracts the guards with gunfire while the other two head in Mikuni's direction. Momoko fights off Sayoko, who attempts to stop them from reaching her mistress, leaving Kuniko to chase after the girl. Kuniko reaches Mikuni and tells her that she can be the successor, but all she wants is to activate the Zeus defense AI, but Sayoko knocks Kuniko down and tells Mikuni to keep moving. Mikuni reaches Ryoko and is told to present the three blade seals to her, though the girl have doubts due to Kuniko's explanation. However, Mikuni is told by Ryoko that she can only be successor if she gets rid of Sayoko. Even though Mikuni doesn't want to, Sayoko sacrifices herself by jumping to her death in order to make her the successor. When Mikuni and Sayoko enter the ceremonial hall, Kuniko grabs Mikuni with her and tells her that all she needs is to speak with Zeus. Upon interacting with a weird device which is used to activate Zeus, Kuniko realizes that Zeus cannot be controlled as she's not the successor. Ryoko reveals herself to be Zeus' avatar, and she easily beats down Kuniko. Despite Kuniko's pleas, Mikuni pushes ahead to destroy the world to avenge Mi-ko's death. When Kuniko tells Ryoko she will stop them, Kunihito appears, pointing his weapon at her.
