History NightmareFuel / VivyFluoriteEyesSong

* [[spoiler: What happened to Ophelia. The original Ophelia was overwritten by her partner and manager, Antonio, who decided to fulfill her mission for her. He piloted her body for years and committed suicide through her in the original timeline. Worse is Antonio's realization that part of the reason he did it was because he only wanted her to sing for ''him'' and that Ophelia had no idea what he was going to do to her.]]
* The ending of episode 10. [[spoiler: The [[RobotWar AI uprising]] that Vivy spent a century trying to prevent [[AllForNothing happens anyway]]. Adding to this the rampaging [=AIs=] are singing Vivy's song in [[VoiceOfTheLegion eerie distorted unison]], as some sort of anthem, while maintaining [[DissonantSerenity completely calm faces devoid of any emotion]] as they proceed to slaughter humans. God help you once you see this scene and hear the singing. It's like they actually raped and corrupted the song itself. You'll never be able to enjoy it anymore.]]
* The reveal of who is behind the AI war. [[spoiler: The Archive, the sum collective memory access of all AIs, which decided that humans had become obsolete, and must be replaced by AIs that can emulate humans. What’s even more horrifying is that it was inspired by seeing Vivy compose a song, proving AIs could be capable of human creativity.]]

* The ending of episode 10. [[spoiler: The [[RobotWar AI uprising]] that Vivy spent a century trying to prevent [[AllForNothing happens anyway]]. Adding to this, the rebelling [=AIs=] are singing the show’s ending theme, which was written in-universe by Vivy, as some sort of anthem as they proceed to slaughter the humans.]]

* The series starts with cheerful people at NiaLand Amusement park, families and kids. Within what seems like five minutes, it descends into bloody violence and carnage, with the DissonantSerenity of the AIs making everything extremely unnerving. Special mention goes to the assistant asking if she can help a woman while crushing her skull, and the singer on the Main Stage performing her routine while her audience is being killed.
