History YMMV / Kiznaiver

** Tenga/Chidori get this as well, largely due to their similarities to [[Anime/TengenToppaGurrenLagann Kamina and Yoko]].

** Red vs Blue, a term to describe the ShipToShipCombat between Chidori (Red) and Noriko (Blue) over Katsuhira. Shipping in general is named after the dominant colors of the girls and their respective crush. In addition to Teams Red and Blue mentioned, there's also Team Orange is for Nico/Tenga. Often, EngineeredHashtags will be added to the name.

* BaseBreaker:

** To a degree, it happened to all characters who were even [[BaseBreaker Base Breakers]]: Chidori was getting hate after starting to show ItsAllAboutMe tendencies, Katsuhira was being accused of being a bland character, Tenga for being a {{Hypocrite}} in episode 9, and so on. Epsiodes 10 and 11 focus on their issues, getting over them and starting to care more for the people around them, such as Chidori [[spoiler: finally understanding that she made Tenga go through the same pain she went]], Katsuhira [[spoiler: becoming NotSoStoic, doing a SkywardScream after meeting the original Kiznaivers and wanting everybody to be friends again]], and Tenga [[spoiler: showing tendencies of wanting to be friends again, and wanting Chidori to properly turn him down and intending to do this to Nico, so they can all have closure.]]

** Nico's popularity blew up similarly to Tenga's on tumblr particularly, due to her quirky personality and overall cute/weird design. This being similar to how Mako's popularity in the Anime/KillLaKill fandom grew.

* IronWoobie: Nico shows signs of this as [[spoiler: she is completely willing to deal with her unrequited love and her pain so they can all be friends again]], even after everything in episode 9, she states how that was the best summer of her 17 years.

* CounterpartComparison: Hajime was instantly compared to [[Anime/TengenToppaGurrenLagann Kamina]].

** Tenga/Chidori get this as well, lergely due to their similarities to [[Anime/TengenToppaGurrenLagann Kamina and Yoko]].

** Chidori, is she an generic character whose love for Katsuhira is stealing the spotlight from the other characters or a complex character whose love for Katsuhira makes her more compelling. After Episode 9 the fandom is split on whether [[spoiler: she's entitled to focus on the pain of her broken heart after Katsuhira completely ignored the heartfelt confession she has been working on for so long, or if she's a selfish person that is more focused on her own romantic feelings without considering Katsuhira's wellbeing after finding out his massively tragic backstory and trauma.]]

* AssPull: [[spoiler: Nico's crush on Tenga really comes from out of left field, as there really isn't a lot of implication that she likes him, except for the passing scene where she curiously watches Tenga try to talk up Chidori to Katsuhira in episode 5. It's possible it was written in just to make the emotional trauma in episodes 8 and 9 more intense.]]

* GrowingTheBeard: Episode 9 is where the series truly started to become DarkerAndEdgier on an emotional scale, and episode 10 continued this trend.

* MemeticMutation: Red vs Blue, a term to describe the ShipToShipCombat between Chidori (Red) and Noriko (Blue) over Katsuhira. Shipping in general is named after the dominant colors of the girls and their respective crush. In addition to Teams Red and Blue mentioned, there's also Team Orange is for Nico/Tenga. Often, EngineeredHashtags will be added to the name.

* NarmCharm: Yuta's GirlyRun in episode 7 should ''not'' make for a heartwarming moment, but it does.

** Sonozaki's [[WhenSheSmiles smile]] in episode 10 has gone viral, usually with comments about how her beautiful smile makes her the best girl, or people supporting Team Blue.

* MemeticMutation: Red vs Blue, a term to describe the ShipToShipCombat between Chidori (Red) and Noriko (Blue) over Katsuhira.

** The children [[spoiler: in the first Kizna experiment. The side effects of the project led to several of them losing all of their senses and unable to live among society. The others, like Katsuhira, weren't much better off, being almost completely devoid of emotion and unable to feel pain. Meanwhile, Sonozaki had to cope with all the pain of ''eighteen other children'' being passed onto her, and now has to be heavily medicated in order to survive.]]

** Chidori as well in episodes 8 and 9. After episodes of her getting several hints that [[spoiler: Katsuhira is infatuated with Sonozaki and barely acknowledges Chidori's current feelings for him, in Episode 9 he unceremoniously leaves her ''while she's confessing her feelings to him'' to (literally) run after Sonozaki.]] Then in Episode 9 [[spoiler: the Kiznaiver experiment puts her along with the other five protagonists in a video room to watch Katsuhira and Sonozaki's subsequent interaction in the gym, and Chidori has to listen to the boy she likes telling another girl that he constantly thinks about her, and to Sonozaki claiming that she and Katsuhira have met in the past, and so Chidori isn't even his only childhood friend anymore]]. It's nearly impossible to not feel for the girl when she reacts by kneeling and covering her ears due to emotional pain.

* RomanticPlotTumor: Many viewers feel that the ShipTease and the love triangle between Katsuhira, Chidori and Sonozaki are consuming screentime that could focus on other things.

* TakeThatScrappy: A lot of fans were starting to get angry at Katsuhira for [[spoiler: blatantly ignoring Chidori's feelings to go for Sonozaki]], even fans that actually did liked him, so when [[spoiler: Tenga punched him for it]], a portion of the people rejoiced.

** Chidori as well in episodes 8 and 9. After episodes of her getting several hints that [[spoiler: Katsuhira is infatuated with Sonozaki and barely acknowledges Chidori's current feelings for him, in Episode 9 he unceremoniously leaves her ''while she's confessing her feelings to him'' to (literally) run after Sonozaki.]] Then in Episode 9 [[spoiler: the Kiznaiver experiment puts her along with the other five protagonists in a video room to watch Katsuhira and Sonozaki's subsequent interaction in the gym, and Chidori has to listen to the boy she likes telling another girl that he constantly thinks about her, and to Sonozaki claiming that she and Katsuhira have met in the past, and so Chidori isn't even he's only childhood friend anymore]]. It's nearly impossible to not feel for the girl when she reacts by kneeling and covering her ears due to emotional pain.

** Many fans thought the reveal of [[spoiler: Nico having feelings for Tenga in episode 8]] was this, given that the clues for it were ''so'' subtle that one could not be blamed for not seeing them at all. Doesn't help that [[spoiler: Nico's direct interactions with Tenga]] before the reveal could've been chalked up to the former's IJustWantToHaveFriends attitude, while the actual romantic hints were more focused on jealousy towards a rival, [[spoiler: Chidori]], and the real ShipTease moment came ''in the same episode'' as the reveal itself. One could only really connect the dots together when other characters pointed it out as if EveryoneCanSeeIt had been taking place all along, despite [[InformedAttribute [[spoiler: Nico's]] feelings being not nearly as obvious as they made them out to be]].

* TheWoobie: Nico, specially after episode 9: [[spoiler: she is in the bottom of the [[AllLoveIsUnrequited Unrequited Love Chain]], and Tenga blatantly ignores her feelings, even when she is clearly hurt right before him.]]
