Embryo is not happy with Salia as he punishes her for letting Ange escape and tells her that his new world would be only for intelligent women. In the maintenance room of the Aurora, Nonna and Mary lament the passing of Marika. Meanwhile, Riza reveals that Embryo plans to merge the two worlds together by using Aura and Ragna-mail. When Hilda and Sala talk about forming strategic alliances with the provision that they bring back Ange, Emma, who is being manipulated by Embryo, appears and faces off against them, but then she is interrupted by Sala. Ersha enters into the library, begging Embryo in tears to raise the preschool children from the dead, but he refuses her wish. Ersha realizes that she has been deceived by Embryo and sobbingly digs a grave to bury children’s bodies, and subsequently she deserts to the enemy. In Hilda’s room, Hilda and Rosalie suffer from their stupidity and powerless, and then Rosalie makes up her mind to defeat Chris for Marika. In Jill’s room, Jasmine criticizes Jill, saying that if she had treated Salia civilly, such a situation would not have occurred. Meanwhile, Ange arrives at the place where she had previously spent time with Tusk, which remains untouched since the last time she was there. She reminisces about the past and then bursts into tears. In Salia’s room, Salia makes a firm decision to kill Ange in order to gain acceptance from Embryo. In the medical room of the Aurora, Riza explains that, because Norma have the potential to reveal the full truth about this world, they are kept in quarantine. In a summit conference of government leaders, the leaders ask Embryo to save them from the chaos of the world, but Embryo rejects their request on the grounds that he thinks that they are not necessary in his new world. In Tusk’s room, Ange reads Tusk’s diary, and she is reminded of what Tusk meant to her. As a result, Ange thinks that she cannot live alone and tries to commit suicide, but then the memories of Tusk cross her mind make her persuade not to do it. When Ange thinks of the good old times with Tusk while facing the setting sun, Tusk, who she had presumed dead, appears from behind. Ange is unable believe that Tusk is alive, and she kisses him to determine whether it actually is him, resulting in a happy reunion between the two. When they return to the Tusk’s room afterwards, Ange is surprised and overjoyed to find that Momoca is also still alive and is waiting for her for her with the home-cooked food. Ange calls the Villkiss, and then they prepare for war to combat the crisis situation.
