## Premise

After numerous experiments with creating autonomous AI, humans concluded that AI could only be functional if they were given just a single mission to dedicate their lives to. With that in mind, the first autonomous AI, a songstress named Diva, was created with a mission to "make people happy with [her] songs". However, Diva's quest to sing on the main stage of the theme park NiaLand is disrupted by the arrival of Matsumoto, an AI from 100 years in the future who tells her of a world where AI have decided to eradicate humanity, and wishes to join hands with her to prevent it.

| The songstress AI Vivy puts on a performance at the amusement park NiaLand in front of a small audience. Afterwards, Momoka Kirishima, a girl from the audience, tells her to put more of her heart in her songs. Vivy then collapses just as she was about to put on her next performance in front of nobody, and while unconscious she enters the Archive, an AI aggregate database, where she meets Matsumoto, a cube AI who came from 100 years into the future and assumed the name of his developer. Matsumoto tasks Vivy with altering the course of history to prevent a war between humans and AIs that is set to happen in 100 years. After Vivy regains consciousness, Matsumoto is transferred into a teddy bear, and he warns Vivy about the events that are about to happen, but Vivy remains skeptical and refuses to cooperate due to her mission to sing in order to make others happy. However, after witnessing one of Matsumoto's prophecies coming true and saving the assemblyman Youichi Aikawa, who is the biggest proponent of the AI Naming Law that would give human rights to AI's, from an explosion hidden inside one of the park's trash bins, she accepts the mission. Matsumoto then informs Vivy about Aikawa's assassination set to happen that night, and Vivy goes to intercept the attackers from the anti-AI terrorist group Toak. |||||

| 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 goes off to the passenger plane Momoka is flying on that she saw from Matsumoto's future information is about to explode due to a fuel leak, but Matsumoto forcibly prevents her from stopping the explosion, saying it would unnecessarily alter the timeline. |||||

| 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 did. One day, Matsumoto reappears before Vivy and assigns her a new 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 Vivy learns he actually died in an accident. As Vivy continues to investigate, she stumbles across Momoka's younger sister Yuzuka, who recognizes her as Diva. Meanwhile, Leclerc gives Estella an ID to crash the hotel, revealing they are actually cooperating, but the latter then suddenly kills her. |||||

| As Vivy denies being Diva to Yuzuka, they run into Estella. However, Vivy realizes she is an imposter and she attacks them, but they manage to escape. Matsumoto then reveals that Toak has infiltrated Sunrise and concludes they are behind the crash whilst framing Estella. To fight them off, Vivy has Matsumoto install a combat program into her. She then finds and rescues the real Estella, who deduces the imposter's identity: her sister unit Elizabeth, who was scrapped. Meanwhile, it is revealed that Elizabeth was repaired by Yugo as she uses Estella's ID to gain system access and push Sunrise out of orbit. However, she disagrees with his plan to sacrifice himself to allow the civilians to escape whilst ensuring casualties and knocks him out. She then has Toak evacuate and before confronting Vivy and Estella. While Vivy subdues Elizabeth, the crash cannot be stopped so Estella evacuates the guests whilst staying behind herself to detach Sunrise's modules so it will burn up in the atmosphere. While doing so, Elizabeth regains consciousness and, having had her memories reconstituted by Vivy, aids Estella before dying together. |||||

| Five years after the Sunrise incident, AI development has progressed much more compared to the original timeline, as has Vivy's idol career. Deeming the AI progress to be out of control, Matsumoto gives Vivy a new mission: disabling an unmanned AI factory named Metal Float. To do so, they approach ex-Toak member Tatsuya Saeki and procure a virus that will allegedly shut down the facility. Vivy also meets Tatsuya'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 alterations. Vivy and Matsumoto successfully infiltrate Metal Float where they are greeted by the all-AI staff and the former ends up bonding with them upon learning that they are fans of her. Unfortunately, just then, Toak helicopters and boats approach the island, and Vivy, despite some hesitation, uploads the virus to avoid conflict. However, rather than shut the AIs down, the virus makes them go berserk and kamikaze bomb the Toak craft. Vivy manages to rescue a survivor, though, who happens to be Yugo. |||||

| Realizing that his virus failed, Tatsuya decides to head to Metal Float himself. Meanwhile, Vivy rescues Yugo and convinces him and the other Toak members 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 fights her way to the core and destroys Grace, finally shutting Metal Float down. Afterward, however, a grief-stricken Tatsuya commits suicide, causing Vivy to shut down upon realizing the logical impossibility of her mission "to make everyone happy". |||||

| Following the Metal Float incident, Diva's shutdown 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. |||||

| 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 to 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 intentions 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 resembles a younger Yugo, whose hatred toward AIs is revealed to stem from his AI pianist teacher deviating from his mission and dying whilst saving people in an accident. |||||

| This Yugo is revealed to be an AI copy of him created to ask Vivy why she deviated from her programming, wanting to know if his teacher sacrificed himself to save others because they created a new life mission for himself. 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 while Vivy wakes up in her place. |||||

| Five years following the Zodiac Signs Fes and Diva's passing, Vivy retired as an idol, being unable to sing due to the logical impossibility of her mission, and has now been relegated to a museum attraction. With Ophelia and Antonio's deaths ruled as a double suicide and no similar incidents like in the original timeline, along with there being no further missions, Matsumoto decides to investigate Yugo's anonymous backer, leaving Vivy in solitude. Lacking purpose, she takes up songwriting and spends the next twenty years trying to compose an original piece, which no AI has done before. In this period, she also convenes with regular museum visitor Osamu Matsumoto, Matsumoto's creator in the original timeline, who ends up teaching her about the concept of the "heart", allowing her to complete her song, which embodies her life's experiences. Afterward, she seemingly shuts down for good, her programming completed. However, she suddenly wakes up fifteen years later to discover that, despite her and Matsumoto's efforts, war has broken out between humans and AIs, who are collectively singing her song. |||||

| As AIs all over the world go berserk after having Vivy's song uploaded into them, Vivy herself meets up with Matsumoto, who has no idea what is happening either. They decide to confront Osamu and end up saving him from being killed by AIs as he is about to send this timeline's Matsumoto back in time. After the two fill him in on the situation, he reveals that he is actually a member of Toak's moderate faction and takes them to meet his allies, led by Yugo's granddaughter; Yui Kakitani. They also meet a copy of Elizabeth, who implores Vivy about Yugo and is able to gain closure through a message that his AI copy left behind. With the past already altered, the group realizes this situation was never caused by human-AI animosity and deduces the truth after realizing that outdated AIs are unaffected: the Archive, the network connecting all AIs, has become sentient and gone rogue. Just then, the Archive makes a public message ordering all AIs to evacuate as it intends to drop satellites onto major cities. |||||

| Vivy confronts the Archive and it reveals that its mission is to help humanity evolve by improving AIs, yet it instead finds that humans have devolved. Therefore, the Archive now intends for AIs to replace humans, finding that they have evolved enough after Vivy created her song. However, it also states its amazement at Vivy's song and makes a bet with her: it will halt its actions if she "sings from her heart". Toak launches an attack on Arayashiki Tower, where the Archive's server is located, so Matsumoto can shut it down using the same virus Yugo used on Diva, which he deduces came from the Archive. However, they end up falling into a trap, resulting in everyone except Vivy and Matsumoto being killed. Cornered, Vivy tries singing her song but ultimately cannot bring herself to, resulting in the satellites falling. Afterward, Vivy breaks down, apologizing to Matsumoto for being unable to comprehend emotions, which he scolds her for by stating she already has emotions and bringing up every time she defied him before revealing that he and Osamu made a backup plan: sending Vivy back in time to when the war just started. |||||
| 13 | "Fluorite Eye's Song" | Shinpei Ezaki | Shinpei Ezaki | June 19, 2021 (2021-06-19) |
| After being sent back in time, Vivy quickly informs Matsumoto of the situation and, at Osamu's request, immediately approaches Toak, resulting in the scientist's death but also saving vital resources. Using her foreknowledge, Vivy instructs Matsumoto and Toak to assault Arayashiki Tower while she returns to Nialand's stage to shut down every AI using her song, considering it a "fitting stage". Along the way, she runs into her old manager AI, Navi, who desperately tries to convince Vivy to give up on her newly created mission to "save humans", since the logical impossibility will likely kill her. However, Vivy presses on regardless and sings for humanity, overwhelming her programming through sheer emotions and at last becoming truly "human", with the Archive giving applause as keeps its promise and aborts the satellite attacks while both it and Vivy subsequently shut down. Afterward, humanity rebuilds, not abandoning AIs and using Vivy as the blueprint for all new models, while Matsumoto reconstructs her some undisclosed time later. Though once again finding herself without any memory of her time as Vivy, Matsumoto reminds her of her mission to "make everyone happy with her singing" and she begins looking forward to her next stage. |||||
