Vivy 拯救 Aikawa 以阻止 AI 戰爭，同時避免時間線改變

Matsumoto informs Vivy of the dire consequences that Aikawa's death, as well as the imminent destruction of the AI company building they are currently trying to escape, would jumpstart a massive leap in AI development and evolution that will lead to the future war. Saving Aikawa's life means there will be no chance the AI Naming law will be passed. Vivy rescues Aikawa and attempts to escort him out of the building with Toak in pursuit. Matsumoto stalls the attackers by hacking their goggles and making them believe they killed Aikawa. At the front entrance, Matsumoto activates some of the bombs to stall the pursuers. However, they are ambushed with more attackers stationed at the entrance. Vivy saves one of the attackers, Yugo Kakitani, from falling debris despite being an enemy due to her mission to spread happiness and not kill anybody. With the entrance blocked, Vivy and Aikawa escape by collapsing the building to force the Toak attackers to flee, and going to the roof to jump off of it to a neighboring building. Shortly after rescuing Aikawa, Vivy is informed about a passenger plane Momoka is flying on that is about to explode due to a fuel leak, but is prevented from stopping the explosion due to Matsumoto's directive to avoid unnecessary alterations to the timeline.

Vivy 調查一起涉及失控 AI Estella 的太空酒店墜毀陰謀

Fifteen years have passed since Vivy saved Aikawa and more people have come to see her performance. While the AI Naming Law ultimately did not pass, another legislation that granted AIs even more rights was created instead. One day, Matsumoto reappears before Vivy and assigns her a mission: to prevent the space hotel Sunrise from crashing to Earth when its owner, Sisters AI Estella, goes rogue, which would cause mass AI backlash. While still bitter about Momoka's death, Vivy agrees to help. However, after infiltrating Sunrise and meeting Estella, she is unconvinced that she is the culprit. Fellow AI employee Leclerc claims to Vivy that Estella killed the Hotel's previous human owner, but this is proven false as Vivi learns he actually died in an accident. As Vivi continues to investigate, she stumbles across Momoka's older sister Yuzuka, who recognizes her as Diva. Meanwhile, Leclerc is revealed to actually be cooperating with Estella to crash the hotel when the latter suddenly beheads and kills her. (Source: Wikipedia)

Vivy在太空戰中擊敗冒牌Elizabeth後坦承身份

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. (Source: Wikipedia)

Vivy 和 Matsumoto 潛入 Metal Float，摧毀 AI 工廠並阻止技術的急速發展。

Five years after the Sunrise incident, AI development has progressed much more compared to the original timeline, as has Vivy's idol career. Matsumoto reappears with a new mission: to slow down the out-of-control AI progress by disabling an unmanned AI factory named Metal Float. To do so, they approach ex-Toak member Dr. Tatsuya Saeki and procure a virus from him that will allegedly shut down the facility. Vivy also meets Saeki's AI attendant, Grace, and Matsumoto explains that they were the first human-AI couple in the original timeline, which now never happened due to their alternations. Vivy and Matsumoto successfully infiltrate Metal Float where they are greeted by the all-AI staff. Unfortunately, just then, a Toak flotilla attacks the island and Vivy, despite some hesitation, uploads the virus into the AIs to avoid conflict. However, rather than shut them down, the virus makes the AIs go berserk and use themselves as kamikaze bombers to destroy the Toak ships. Vivy manages to rescue a survivor, though, who happens to be Kakitani. (Source: Wikipedia)

Vivy 與 Tatsuya 對峙並摧毀 Grace 以關閉 Metal Float

Realizing that his virus failed, Tatsuya decides to head to Metal Float himself. Vivy is able to rescue Yugo and the other surviving Toak invaders and convinces him to retreat from Metal Float. Learning that Tatsuya is on the island, Vivy and Matsumoto confront him and he reveals his motives: while he fell in love with Grace like in the original timeline, due to the alterations made to history, she was converted into Metal Float's central core before he could propose to her. He also reveals that his attendant is merely a replica of Grace that he intended to transfer her consciousness into after the facility was shut down, but the virus has instead caused the island to go berserk due to it conflicting with Grace's programming. Ultimately, despite Tatsuya pleading with Vivy to help him save Grace, Matsumoto assures her that she is already beyond saving and she reluctantly resolves to euthanize her to avoid further casualties. Vivy then proceeds to fight her way to the core and successfully destroys Grace, finally shutting Metal Float down. Afterward, though, a grief-stricken Tatsuya commits suicide, causing Vivy to suffer a mental breakdown. (Source: Wikipedia)

Diva Rebooted：偶像突襲與松本的秘密任務

Following the Metal Float incident, Diva's mental break forced her to undergo a complete reboot, causing her to lose all memory of her time as Vivy. Forty years later, she is now a legendary idol set to perform on her dream stage during the Zodiac Signs Fes, a festival created to dispel human-AI discord. There, she meets fellow songstress AI Ophelia, who is a fan of hers. However, while rehearsing Diva notices a suspicious man and gives chase but is ambushed by a hacked factory AI. Fortunately, she is saved by the timely appearance of Matsumoto, who calls her "Vivy". Realizing they knew each other before she lost her memory, Diva tries to talk to him but he denies ever having met her. Before the show begins, though, she once again confronts Matsumoto and blackmails him into revealing the truth. Matsumoto tells her about their past exploits, but she is skeptical and decides to confront the suspicious man instead. However, Matsumoto has no idea who this individual is and decides he must act quickly to complete his current mission: to prevent Ophelia from committing suicide. (Source: Wikipedia)

獻給唯一摯愛的愛情輓歌

Matsumoto explains that, in the original timeline, Ophelia's suicide, which was unprecedented for an AI, sparked a string of similar incidents. While the amnesiac Diva remains skeptical, she does not want Ophelia to die and asks her if there is "something that would make her want to commit suicide". Confused, Ophelia tells Diva about her old manager AI Antonio, the only person who would encourage her when she was a struggling newbie idol, who mysteriously shut down a few years ago. While Matsumoto plans to just physically restrain Ophelia, Diva argues that would not change her intend and decides to confront her again after her show, only to end up being captured by the suspicious man. Meanwhile, Matsumoto, who had been watching Ophelia through security cameras, realizes the cameras were hacked and rushes to stop her suicide. However, upon confronting her, it is revealed that Ophelia is actually Antonio, having taken over the real Ophelia's body. Elsewhere, Diva wakes up to find she has been captured by the suspicious man, who looks just like a younger Yugo. (Source: Wikipedia)

AI複製的Yugo與Vivys對峙，Matsumoto則與Antonio戰鬥以拯救Diva

This Yugo is revealed to be an AI copy of him created to ask Vivy why she deviated from her programming, revealing that his hatred for AIs stems from his AI pianist teacher deviating from his programming and dying whilst trying to save people in a car accident. Meanwhile, Antonio attacks and hacks Matsumoto whilst criticizing him for only existing for his programming. However, Matsumoto is able to break free by admitting that he cares for Vivy and hacks Antonio, breaking his control over Ophelia but also fatally damaging them, with them admitting their love for each other in their final moments. Back with Vivy, Yugo uploads a virus to restore her memories as Vivy at the cost of her current personality as Diva. Fortunately, Matsumoto comes to her rescue and a fight ensues which ends with Yugo being fatally damaged. Noticing that Yugo had technology from the future, Matsumoto questions him and he reveals he got it from an anonymous source before dying after telling Diva to realize her contradictions. Realizing she does not have long due to Yugo's virus, Diva spends her final moments performing before shutting down for good whilst Vivy wakes up in her place. (Source: Wikipedia)
