Yuzuka asks Vivy if she is Diva, but Vivy is forced to deny it to keep her cover. Vivy and Yuzuka run into Estella, but Vivy notices that she is not wearing her wristband and realizes she is an impostor. The impostor attacks and damages Vivy's right arm, but Vivy and Yuzuka escape. The two end up in the cargo bay where Vivy sees Leclerc's body and replaces her damaged arm with Leclerc's. Matsumoto then arrives and confirms that the Sunrise crash was actually caused by Toak so they could frame Estella and blame AI. Determined to protect Yuzuka, Vivy has Matsumoto download a combat program into her. She knocks out several Toak soldiers before finding Estella, who realizes that the imposter must be her sister unit Elizabeth, who was supposed to have been scrapped. Meanwhile, Elizabeth uses Estella's ID to take Sunrise out of orbit, and it is revealed that she was found and repaired by Kakitani in order to carry out this plan. Having grown loyal to Kakitani, Elizabeth knocks him out and convinces his men to evacuate with him while she goes to confront Vivy and Estella herself. Vivy is able to subdue and reformat Elizabeth's memories, but is forced to evacuate while Estella stays behind to detach Sunrise's modules so it will burn up safely in the atmosphere. On the evacuation ship, Vivy admits to Yuzuka that she is Diva. Elizabeth regains consciousness and helps Estella detach all of Sunrise's modules. With their task complete, both Estella and Elizabeth sing over the radio to calm the evacuating passengers as their module burns up in the atmosphere.
