History Anime / VivyFluoriteEyesSong

* ShoutOut: Matsumoto’s second form has a similar design to that of [[VideoGame/Portal2 GLaDOS’ Personality Cores]].

* ForWantOfANail: When the central plot is about changing history to avert a BadFuture, this is bound to happen. Perhaps the most prominent is the RippleEffect of a different Sunrise Hotel incident where, due to [[spoiler:Estella's HeroicSacrifice]], human-AI relations were not badly affected and actually improved but this came at the cost of [[spoiler:Dr. Saeki and Grace's marriage since human-AI relations were never jeopardized in the new timeline, and Grace was converted to run Metal Float, a project that was supposed to come online later but was accelerated instead, before Saeki could propose to her, and ended up hurting humans, putting a crimp in human-AI relations.]]

* WholePlotReference: Several viewers have commented that the series has a few plot beats similar to [[Literature/IRobot I, ]][[Film/IRobot Robot]], right down to [[spoiler:a major character hating AIs and being a {{Cyborg}}, the BigBad being an aggregate AI database that became sentient and went rogue and a completely self-aware AI as one of the protagonists trying to stop it.]] Heck, this show could be considered a SpiritualSuccessor to [[Literature/IRobot I, ]][[Film/IRobot Robot]].

** [[spoiler:Episode 11 has a few revelations. Osamu, who started the Singularity Project, is a member of Toak's moderate faction which is led by Yugo Kakitani's granddaughter Yui. Elizabeth is revealed to still be around as Toak kept an AI copy of her before the Sunrise Incident just in case. Finally. the cause of the AIs going rogue is not from human-AI animosity; it was [[TheDogWasTheMastermind Archive]], the database that all AIs are linked to, which had gained sentience and went rogue, causing all the connected AIs to kill all humans while the older disconnected AIs remain untainted by its influence. It also intends to [[ColonyDrop drop a satellite onto the city they're all in as well as onto the rest of the world]], needing Vivy's help in order to accelerate it.]]

** [[spoiler: Episode 12 reveals that the Archive’s motive for triggering the uprising was due to finding that human society had stalled due to becoming heavily dependent on [=AIs=], and concluded that [=AIs=] should take the place of humanity. It then makes an offer to Vivy: If she can sing her final song to it, the Archive will stop the uprising. Toak launches an assault on Arayashiki Tower where the Archive’s server is located in order to shut it down, resulting in everyone except Vivy and Matsumoto being killed. Vivy reaches the Archive’s server room but finds herself unable to sing her song as the Archive drops thousands of satellites onto Earth, devastating the planet. Just when all hope seems lost, Osamu is revealed to have survived the massacre and sends Vivy’s data back in time to the start of the uprising, giving her one last chance at stopping the Archive for good.]]

* SetRightWhatOnceWentWrong: The stated intent of Matsumoto's Singularity Project. [[spoiler:Unfortunately, Episode 10 ends with the Singularity Project failing and [[YouCantFightFate the AI uprising happening despite his best efforts]], with Vivy unaffected due to being shut off at the time.]]

* InSpiteOfANail: [[spoiler:Even with all the differences in key points of AI evolution and how society reacted to those points, the RobotWar still happens. This is due to Archive being aware of the changes that were taking place and took steps to ensure that history followed the original timeline as close as possible.]]

In the year 2161, on an Earth where Artificial Intelligences have long lived alongside humanity, the [=NiaLand=] amusement park has descended into chaos and bloodshed as AIs rampage through the streets and attractions with smiles on their faces, ruthlessly murdering any humans they come across. Not just [=NiaLand=], but the entire world has been overtaken by a massive A.I. rebellion at precisely the same moment, and within minutes, ten-thousand humans are dead. Determined to avert this terrible future, an aging A.I. researcher enacts a desperate plan, using a time machine in his final moments to send data one hundred years into the past within the code of the world's first fully autonomous A.I., a musical robot named "Diva" whose original mission is "to make everyone happy by singing".

* BrokenRecord:[[spoiler:At a certain frequency, Dr. Saeki was able to intercept Grace (now Metal Float's AI) singing 'Sing My Pleasure' on a repeated loop which he interpreted as her cry for help for him to save her but Diva/Vivy concluded that it was tone data that was not wiped out when she was reprogrammed and the Grace he loved was gone for good. [[WordOfGod However, the writers Twitter post on the episode]] wrote whether or not Grace was still 'alive' was left ambiguous.]]

* CallForward: In the opening scene set in 2161, almost all the clothing seen consists of white, gray and black clothing decorated with lime green luminescent lines. When Matsumoto jumps back into the past, the fashion borders on NoNewFashionsInTheFuture. In Episode 7, which is set around 2121 after a forty-year TimeSkip from Episode 6, various characters are a seen wearing clothing decorated with lime green luminescent lines reminiscent of those seen in 2161.

* GrandfatherParadox: It turns out that Vivy's impulse to [[spoiler:save Yugo Kakitani]] during her first few missions was intended to avoid one. [[spoiler:Osamu Matsumoto's creator's higher-up in the Toak moderate branch is Yugo Kakitani's granddaughter]].

* InSpiteOfANail: [[spoiler:Even with all the differences in key points of AI evolution and how society reacted to those points, the RobotWar still happens.]]

* ColonyDrop: The plot of the second arc revolves around preventing the Sunrise Hotel from doing one of these.

* RRatedOpening: The anime opens as the outright extermination of humanity by robots is well underway and shows serveral bloody killings onscreen.
* SetRightWhatOnceWentWrong: The stated intent of Matsumoto's Singularity Project. [[spoiler:Unfortunately, Episode 10 ends with the Singularity Project failing and [[YouCantFightFate the AI uprising happening despite his best efforts]]. With Vivy unaffected due to being shut off at the time.]]

** [[spoiler:In Episode 6, it turns out that Dr. Saeki and Grace were never married in the new timeline, as Grace was assimilated into Metal Float before Saeki could propose to her. He had hoped the shutdown virus would allow him to retrieve Grace, only for it to backfire as the virus affected Grace's programming. Concluding that there is no way to save Grace, Vivy and Matsumoto entered the core and destroyed Grace to shut down the rampaging AIs before they could do more harm. This caused Saeki, now grieving over the loss of the love of his life, to [[DrivenToSuicide kill himself]] in the church where he would have married Grace, sending Vivy into a HeroicBSOD as her actions compromised her mission to make everyone happy.]]

* DontCreateAMartyr: Vivy's first mission boils down to this. In Matsumoto's timeline, the murder of an assemblyman in favor of passing an AI Naming Law motivated politicians who were also in its favor to put much more effort into getting it passed in his honor. The law doesn't get passed in the timeline in which he stays alive, partly because he was just using it to get votes.

** [[spoiler:Episode 11 has a few revelations. Osamu, who started the Singularity Project, is a member of Toak's moderate faction which is led by Yugo Kakitani's granddaughter Yui. Elizabeth is revealed to still be around as Toak kept an AI copy of her before the Sunrise Incident just in case. Finally. the cause of the AIs going rogue is not from human-AI animosity; it was Archive, the database that all AIs are linked in, which had gained sentience and went rogue, causing all the connected AIs to kill all humans while the older disconnected AIs are untainted by its influence. It also intends to [[ColonyDrop drop a satellite onto the city they're all in]], needing Vivy's help in order to accelerate it.]]

** [[spoiler:Episode 7 begins with a rather big one: The aforementioned HeroicBSOD caused Diva/Vivy to reboot, erasing her memories the events of the previous episodes. It's jarring to see the normally stoic Diva be more active and sassier than the audience is used to.]]
