In this case, Dian had planned to avenge her native Glacies by attempting to kill Luscinia as she knows that he is responsible for it. A conference presided by Sara is held between the rebel alliance led by Vasant, Orang and Millia; and the Ades loyalists led by Luscinia, Sadri and Liliana, with the aim of discussing a peace treaty between both sides with representatives of the Sky Pirates (Fam, Giselle and Atamora), Anatoray (Tatiana and Alister) and Glacies (Dian and Magnolia) in attendance. Luscinia reveals his actions of conquering the other nations was to save Earth, as the Exile nations are depleting the planet's resources too fast. He had to forcefully unite the world under Ades rule in order save everyone from themselves no matter how many are sacrificed. As both sides argue each other over what the other side did and their justification of their actions, particularly between Vasant and Luscinia, Sara has enough and orders both of them to stop as she doesn't want to see them fight anymore and asks Luscinia to abandon his plans, and Vasant to let go of her desire for revenge against him. With Fam, Sadri, Atamora and Orang supporting the notion as well, the other leaders follow suit which convinces both Vasant and Luscinia to make peace, ending the war. As everyone celebrates the new peace at a party, not everyone is satisfied, particular Dian. Sadri has a dance with Fam and asks about her parents and family life, as he has a suspicion that Fam is related to him. Millia is secretly taken by a group of Turan officers who wants her to kill and overthrow Liliana from the throne for betraying Turan but they are apprehended by Alauda and his men, who brings Millia to meet Luscinia at the White Legacy, the former headquarters of the Guild. Luscinia reveals the history of the Guild over how they were tasked to save and protect the human race before becoming corrupt. Millia is reunited with Liliana who the former demands answers on why her sister help and supported Luscinia actions. Liliana revealed she did it to help Luscinia save the world, even if her actions would make people hate her, which she doesn't care as long as Millia was safe, which both sisters reconciled. The next day, the signing of the peace ceremony is about to begin but Dian attempts to kill Luscinia only for Liliana to block her. As Liliana dies in Luscinia's arms who grieves over losing another loved one, Millia runs towards her sister only to go into shock after the ability to control Turan's Exile transfers to her; as well as a vision, which made Millia understand her sister's reasons.
