History YMMV / SayonaraZetsubouSensei

* HarsherInHindsight: The "promotional manga" informing the public on the use of spent nuclear fuel in manga Volume 4, supposedly put out by a PaperThinDisguise for the Tokyo Electric Power Company (TEPCO) (complete with Maria [[FauxSymbolism briefly turning into a marionette with visible strings]]). TEPCO of course became the most notorious utility company in Japan (and perhaps the world) after the 2011 Fukushima meltdown.

* LesYay: Chie and Kiri on occasion.

* {{Squick}}[=/=]NauseaFuel: The chocolate heart that Chiri made for Valentine's Day. How? It's a ''realistic looking'' chocolate heart. Half of it.

** Starting with Volume 5, the English edition of the manga goes from being translated by Jason Thompson to David Ury. There are now much fewer annotations for the references and cultural notes, and the wording of all the character's catchphrases has changed. It's definitely a mixed bag, though. Vol. 5 doesn't have nearly as many dense references, and a lot more of them are directly explained in the text; the really unfamiliar things are still explained. The original translation of Zetsubou-sensei's CatchPhrase wasn't exactly like what we're used to, but changing it to "I've lost faith in [whatever]" is a major downgrade. The new translation also downgrades Kafuka's blatant CloudCuckooLander-ness, although Chiri is still just as much of a psycho. Volume 9 saw Ury being replaced with Joeshua Weeks, who isn't as good at including explanations of references right in the text but at least makes sure to use the phrase "I'm in despair" more often than Ury.

* ThisIsYourPremiseOnDrugs: SliceOfLife on crack and acid.

* TheWoobie: Maria, who woobifies herself and even makes Nozomu pity her.

* BigLippedAlligatorMoment: [[WidgetSeries Being the series it is]], there is a lot in the anime. One memorable moment in particular during Matoi's story in Season 1, where she runs off from Arai's office, it suddenly switches to... [[MindScrew whatever that was]].

%%* WidgetSeries: Needs more context.

* EnsembleDarkhorse: Chiri gets an awful lot of fan art dedicated to her, and [[SpotlightStealingSquad she seems to get more screen/panel time]] than any of the other Despair Girls except maybe Kafuka (who's probably closer to a main character since she's explicitly Nozomu's foil). I guess people like their {{Yandere}} [[PsychoKnifeNut Knife]]/[[ShovelStrike Shovel nuts]]?
** It's quite possible to say that nearly every single recurring or main character has their own fandom.

* AcceptableTargets: Frequent targets including pervy {{otaku}} or {{NEET}} guys, immigrants, and [[strike:China]] "a certain country" whose constant spying on Japan goes unacknowledged by the government for political reasons (North Korea gets a similar treatment).

** Chiri and Fujiyoshi, who are childhood friends, are already proving to be quite a popular couple as well, and have several hints scattered around. Even Ryogo Narita, the author of ''LightNovel/{{Durarara}}'', ships them.

* HilariousInHindsight: In response to the [[LightNovel/{{Durarara}} Shizuo and Izaya]] pairing, Ryogo Narita, the author of ''LightNovel/{{Durarara}}'', said that he couldn't say anything because he likes to ship Harumi and Chiri. One chapter shows that Harumi is indeed a Shizuo/Izaya fan. Although it's difficult to say which came first without a proper time reference.

* FunnyAneurysmMoment: The last picture of Chapter 16, "The People Are At The Breaking Point", depicts the cooling tower of a nuclear power plant cracking and saying "kaboom". This predates the Fukushima Nuclear Plant crisis by 5 and a half years.
** From a few chapters later...
-->'''Nozomu''': ''To get a stable electrical supply, we have unstable nuclear plants!''

* EnsembleDarkhorse: Chiri gets an awful lot of fan art dedicated to her, and [[SpotlightStealingSquad she seems to get more screen/panel time]] than any of the other Despair Girls except maybe Kafuka (who's probably closer to a main character since she's explicitly Nozomu's foil). I guess people like their {{Yandere}} [[KnifeNut Knife]]/[[ShovelStrike Shovel nuts]]?

* ValuesDissonance: Or rather, cultural beliefs dissonance. Nozomu is {{Squick}}ed out by the Christmas holiday because he was born on November 4 and thus follows the still-prevalent Asian belief that the average human gestation period is 10 months and 10 days...thus he thinks he was conceived on Christmas (which, [[UsefulNotes/ChristmasInJapan in Japan]], is celebrated more as a romantic holiday than being about religion or family). It's even worse for [[ButtMonkey Kageru]], since he was born on December 24 and thus believes he was conceived on Valentine's Day--two romantic holidays in one stone.

* MexicansLoveSpeedyGonzales: This manga is ironically quite popular with people who suffer from chronic depression and other similar issues.

* {{Woolseyism}}: One scene in the series is based around portable shrines used in festivals as an analogy for hype. Certain fansubs change this to more-relatable-to-Western-audiences comparisons to things being put on pedestals and jumping on bandwagons (though it still works with the portable shrine imagery).

* ThisIsYourPremiseOnDrugs: SliceOfLife on crack and LSD.

*** Also, ''Kurayami Shinjuu Soushisouai.'' Made even better by the fact that Itoshiki's voice actor does the vocals, quite well too!

* HarsherInHindsight: The "promotional manga" informing the public on the use of spent nuclear fuel in manga Volume 4, supposedly put out by a PaperThinDisguise for the Tokyo Electric Power Company (TEPCO) (complete with Maria [[WhatDoYouMeanItsNotSymbolic briefly turning into a marionette with visible strings]]). TEPCO of course became the most notorious utility company in Japan (and perhaps the world) after the 2011 Fukushima meltdown.

* HollywoodPudgy: Not nearly as much as Nami, but Abiru sometimes complains about her weight. Despite the fact that she gives Kaere a run for her money when it comes to fanservice...infact, she's probably got one of the bigger fandoms among the girls, Kafuka and Keare also having quite big fandoms (one for being...Kafuka, and the other for the obvious).

* AcceptableTargets: Frequent targets including pervy {{otaku}} or {{NEET}} guys, immigrants, and [[strike:China]] "a certain country" whose constant spying on Japan goes unacknowledged by the government for political reasons (North Korea gets a similar treatment).

* CrossesTheLineTwice: Suicide, [[DudeNotFunny not funny]]. Suicidal teacher winning the love and affection of his students by promising to ''take them with him'' when he does it, hilarious.

* BizarroEpisode: More like a Bizarro ''series''.

* HellIsThatNoise: In Episode 4, when Meru "speaks."

** [[BrickJoke "Don't forget to laugh seven years from now,"]], with a countdown date is pretty popular on 4chan.

* HarsherInHindsight: The MagicalGirl opening may nowadays bring back [[NightmareFuel horrifying]] or [[TearJerker tear-jerker]] memories of ''Anime/PuellaMagiMadokaMagica''.
** And then there's the "promotional manga" informing the public on the use of spent nuclear fuel in manga Volume 4, supposedly put out by a PaperThinDisguise for the Tokyo Electric Power Company (TEPCO) (complete with Maria [[WhatDoYouMeanItsNotSymbolic briefly turning into a marionette with visible strings]]). TEPCO of course became the most notorious utility company in Japan (and perhaps the world) after the 2011 Fukushima meltdown.
