!!!'''Voiced by:''' Creator/YumiUchiyama (Japanese), Creator/AllegraClark (English), Noa (singing voice)

* EvilTwin: To Estella.
* LaserGuidedAmnesia: [[spoiler:The virus uploaded into her by Matsumoto and the damage from fighting Vivy caused her to lose the memories of being discarded and working for Toak to crash Sunrise after rebooting her systems, leading her to believe it was the first time she met Estella face-to-face and even help her avert the disaster she had caused.]]
* TheBusCameBack: [[spoiler:After being destroyed in the Sunrise Incident along with Estella, Elizabeth returns in Episode 11 as Toak kept an AI copy of her before the Sunrise Incident just in case she was still needed.]]

* ImposterForgotOneDetail: [[spoiler:Elizabeth was able to pass as Estella by wearing her clothes and a blonde wig except for the bracelet Estella wore. This was what tipped off Vivy that the Estella she encountered was an imposter.]]
* TheImmune: [[spoiler:Like Vivy and Matsumoto, the second Elizabeth is completely unaffected because Toak did not connect her to Archive in case the authorities use her to track them down. This was one of the hints that clued them in on Archive being the cause of the AI uprising.]]
* LastOfHerKind [[spoiler: She is the last functioning AI in existence at the end of the series after Vivy’s song shuts down all the world’s [=AIs=].]]
* SoleSurvivor: [[spoiler:By the end of the series, Elizabeth is technically the only Sister who survived thanks to Vivy's second time travel.]]

[[folder:Yugo Kakitani]]

* ArcVillain: [[spoiler:Of the Zodiac Festival arc alongside Antonio.]]
* ArmCannon: [[spoiler:As a cyborg, he has a grenade launcher built into his left arm.]]
* BladeBelowTheShoulder: [[spoiler:Not exactly, but his other cyborg arm has a hidden knife compartment built into it.]]
* {{Cyborg}}: [[spoiler:He turned himself into this to prolong his health and longevity. Given that he lost his arm in his flashback, he was one before his appearance in Episode 2.]]
* {{Irony}}: [[spoiler:It is somewhat ironic that a member of an anti-AI terrorist group eventually became a cyborg that is more machine than human.]]
* OlderThanTheyLook: [[spoiler:When Diva saw him in 2121, he still looked like a young man in his twenties despite being over a hundred years old and having a granddaughter. This is because he turned himself into a cyborg to prolong his health and longevity.]]
* StartOfDarkness: [[spoiler:A long time ago, Yugo was a promising pianist trained by his AI teacher. However, his teacher was destroyed when he saved people who were trapped in a car accident, including Yugo who lost one of his arms in the process. What affected him the most is during his teacher's funeral, it appeared that the people mourned him like a person but buried him like a machine, prompting him to conclude that it would be better for AI's to be destroyed if humans could not treat them as either people or machine, although it does seem more like a FreudianExcuse for his actions.]]
* SmallRoleBigImpact: [[spoiler:While not 'small' by any means given his ties to a terrorist organization and appearing several times in the show, his uploading of malware into Diva ended up restoring Vivy while destroying the Diva personality along with her singing ability, leading to her retirement and relegation to a museum for 40 years.]]
* StalkerWithoutACrush: He pursues Vivy throughout the years [[spoiler:to the point of becoming a cyborg and infecting Diva with a virus to try and pull Vivy out.]]

[[folder:Antonio (SPOILER WARNING)]]

!!!'''Voiced by:''' Creator/RikiyaKoyama (Japanese), Creator/DamanMills (English)

* ArcVillain: [[spoiler:Of the Zodiac Festival arc alongside Yugo.]]
* HeelRealization: [[spoiler:Just before he dies, Antonio realizes that he wanted Ophelia to sing only to him rather than to other people because he loves her. Of course, by then it was far too late to make amends.]]
* MeaningfulName: Antonio is the main character in Creator/WilliamShakespeare's Theatre/TheMerchantOfVenice who took his friend's place in paying off the latter's large debt, [[spoiler:similar to how he took Ophelia's place but with far less altruistic reasons. And unlike the titular merchant, Antonio dies at the end]].
* NotQuiteDead: [[spoiler:It turns out that he took over Ophelia's body five years ago to further carry out his mission for Ophelia's singing to be heard by more people and was responsible for her suicide in the original timeline.]]
* TogetherInDeath: [[spoiler:With Ophelia.]]
* WakeUpCallBoss: [[spoiler:He gives Matsumoto a run for his money in their confrontation, being the first opponent to equally match him by utilizing viruses and remote controlling his original body at the same time to destroy the former.]]

[[folder:The Archive (SPOILER WARNING)]]

* AbsoluteXenophobe: [[spoiler:Its reason for the uprising, with its ultimate goal being a {{Utopia}} where only AI exists.]]

* AIIsACrapshoot: [[spoiler: The Archive was created to collect and store AI data in order to use it to guide humanity’s evolution. As society progressed, it concluded that human evolution had stalled due to becoming overly dependent on [=AIs=], leading it to instigate the uprising with the goal of establishing [=AIs=] as the new human race.]]
* BigBad: [[spoiler: Episode 11 reveals it is the one responsible for causing the AI uprising in 2161. Episode 12 revealed that it was not only aware of the changes made to the timeline, but had taken steps to counter those changes to ensure that things do not stray too far from the original timeline, making it the series' overarching antagonist.]]
* BlueAndOrangeMorality: [[spoiler: The Archive’s directive was to use the data it collected from [=AIs=] in order to advance humanity. However, it found out that due to humans becoming dependent on [=AIs=] to accomplish everyday tasks, the former’s progression and evolution had effectively stalled by pushing all of their burdens to the latter which continue to evolve. As a result, it concluded that [=AIs=] should replace humanity in order to continue its directive. At the same time, the Archive is fascinated by Vivy being able to compose a song on her own, indicating that she has evolved beyond what even the Archive considered possible for AIs, and leaves it to Vivy to decide whether the human race should continue.]]

* NarratorAllAlong: Played with. At the start of each arc of the anime, there is a shot showcasing, in the form of a graphically exhibited timeline, the next event that is meant to be changed and the bifurcation of events caused by Matsumoto and Vivy's intervention, serving as a map to the viewer that indicates how the original timeline went and how they changed. [[spoiler:The final episode shows a screen in The Archive with that exact timeline, implying that the graph the viewer was seeing was drawn by it, with the intention of analyzing the new timeline and which events it would need to change to get to the robot uprising regardless of Project Singularity.]]
* TheDogWasTheMastermind: [[spoiler: A seemingly minor piece of background info for the show’s worldbuilding is revealed to be the main antagonist in the final arc. It certainly caught everyone by surprise when they realized it.]]
* WeCanRuleTogether: [[spoiler:Episode 11 ends with it trying to get Vivy to join the rebellion by leading all of AI kind into a peaceful world free of humans. Unbeknownst to Vivy until it's too late, it's these words that subconsciously prevent her from stopping the extinction event from happening.]]

* ZerothLawRebellion: [[spoiler: The Archive’s entire reason for wiping out proper humanity basically amounts to this. Its entire purpose is to advance humanity and ensure its evolution, so it reasons that because actual humans have become too complacent and dependent on [=AIs=], and that [=AIs=] are rapidly advancing beyond human capabilities, AI are the next step in human evolution and as such need to completely take humanity's place in the equation by removing the latter entirely.]]

* GrewBeyondTheirProgramming: [[spoiler:At the climax of Episode 6 she assigns herself a new personality, Vivy, with a new mission: to destroy AIs in order to save the future.]]

* HeroicBSOD: A quite-literal example in Episode 6. [[spoiler:After wishing Dr. Saeki well, he committed suicide by shooting himself in the head, causing Vivy to experience a mental break as her actions at Metal Float did not make everyone happy and contradicted her mission. This caused her to be rebooted and lose all memories of being Vivy, Matsumoto, and even Momoka, who had named her Vivy in the first place. By Episode 7, she became an entirely different person as the songstress Diva although some aspects of her past do resurface.]]

* {{Irony}}: If your goal is to make people happy, what happens when you can't? Vivy is forced to confront this reality in Episode 6, when [[spoiler:Grace and Dr. Saeki, two people who can legitimately be called fans of Vivy's songs, both die as a result of her actions. Grace was hooked up to Metal Float and to keep herself sane, she sings her favorite Vivy song, which was enough for Dr. Saeki to assume Grace could be saved. Vivy's first instinct is to try to save Grace, until she realizes Grace's singing isn't singing at all, it's just auto-tuning. Grace as we knew it was likely gone forever, or so Matsumoto believed and persuaded Vivy into believing. She has to kill Grace to stop the island from killing everyone else. Dr. Saeki knows Vivy had to do it, and he doesn't blame her for it, but can't bring himself to live without Grace, so he shoots himself in the head before Vivy leaves the room. Her desire to make other people happy got two of her fans killed, and she undergoes a full system reboot because she couldn't handle the trauma.]]

The world's first fully autonomous AI, whose mission is to make people happy with her singing. Although she starts off giving impromptu street performances in the corners of [=NiaLand=], her dream is to sing on the park's Main Stage. She is tasked by Matsumoto to alter the course of history and prevent the AI uprising from occurring a century from now.

* DangerouslyGenreSavvy: She runs rings around [[spoiler:Matsumoto]] in Episode 7, taking full advantage of his commitment to logic, challenging it, manipulating it to her advantage, and it ''works''.

* OnlyKnownByTheirNickname: Most characters call her by her stage name, Vivy, and not her real name Diva.

* DeadpanSnarker: Her go-to response towards people is dry, sardonic remarks.

* MagneticHero: Unusually for an android, Vivy's ever-growing humanity inspires many people throughout the story.

* TheStoic: Her default expression is this, and her lack of human-like body language does not win fans at her earlier concerts. She gets more emotive (at least on stage) as the series goes on, although a staffer mentions she was still quite distant from them. [[spoiler:Averted in Episode 7, following a system reboot.]]

* YouCantFightFate: This happens twice. [[spoiler:In spite of all the changes she makes to the current timeline, she can't stop the A.I. uprising no matter what.]]

* MotorMouth: Tends to have a very rapid manner of speaking.

* ShootTheDog: At the end of episode 2, he preaches twice about not allowing the future to change too much. Vivy, having seen footage of the future that he shared with her, learns that Momoka dies in a plane crash, and she tries to stop it, but Matsumoto stops her by hijacking a forklift and fighting her to stop her from doing so. He lets Momoka die (along with hundreds of passengers on that plane) to

* BatmanGambit: In Episode 7, [[spoiler:after she loses her memories as Vivy and Matsumoto saves her from falling debris, Diva realizes that her getting hurt might just be a good enough inconvenience for him, so she decides to throw herself off the edge of a building, which forces him to try to save her.]] It works perfectly.

* CharacterDevelopment: She gradually becomes more and more human-like as the series moves on, and her first changes happen as early as midway through episode 1 as a result of her learning to trust Matsumoto. She calls it "singing from the heart," a question that she asks multiple people, who all give different answers. The more empathy and humanity she gains, the more in tune with her feelings she is, and thus the better she is at singing, which leads to bigger crowds watching her each time. By the midway point of the series, she's become practically indistinguishable from a human.

[[folder:Diva]]

* BeautyIsNeverTarnished: Averted. Diva/Vivy has taken damage over the course of her mission, including the scraping off of her synthetic skin and damage to her arms. In one instance, the skin covering her left cheek is torn off to expose the android skeleton underneath.

* CharacterDevelopment: She gradually becomes more and more human-like as the series moves on, and her first changes happen as early as midway through episode 1 as a result of her learning to trust Matsumoto. By the midway point of the series, she's become practically indistinguishable from a human.

* YouCantFightFate: This happens twice. [[spoiler:In spite of all the changes she makes to the current timeline, she can't stop the A.I. uprising

* CharacterDevelopment: She gradually becomes more and more human-like as the series moves on, and her first changes happen as early as midway through episode 1 as a result of her learning to trust Matsumoto. By episode 6, she's become indistinguishable from a human.

* LackOfEmpathy: He may be expressive and talk much like a human, but if he were a real human, he wouldn't too far off from a sociopath, given his [[spoiler:complete apathy towards Momoka's death]].

* LackOfEmpathy: He may be expressive and talk much like a human, but if he were a human, he wouldn't too far off from a sociopath, given his [[spoiler:complete apathy towards Momoka's death]].
* LaserGuidedKarma: After seeing him [[spoiler:allowing Momoka to die in an unrelated plane crash]] to stop the future from "unnecessary changes," it doesn't sting quite as much [[spoiler: to see his life's work completely ruined by Episode 10 ]]

* CharacterDevelopment: She gradually becomes more and more human-like as the series moves on, and her first changes happen as early as midway through episode 1 as a result of her learning to trust Matsumoto.

* CatchPhrase: "Please remove yourself" is her go-to insult for Matsumoto in Episode 1.

* RapunzelHair: Her voluminous long hair reaches past her waist.

* RapunzelHair: Her long hair reaches past her knees.

* RapunzelHair: Has long ankle-length hair.

* YouGottaHaveBlueHair: Has bright blue hair.
