History Manga / KoroSenseiQuest

* DenserAndWackier: Take the original story, put it in an RPG setting, remove most of the seriousness and crank the silliness and cuteness UpToEleven and you get ''Koro-Q!''.

** During Pope Asano's game of tag, he catches Mimura while peering between two walls, [[HeresJohnnyHomage making a face that looks exactly like Jack Torrance in the infamous "Here's Johnny!" scene]] from ''Film/TheShining''.

It received an anime film adaptation (also animated by Creator/{{Lerche}}) as a companion for the ''Assassination Classroom: 365 Days'' compilation film, which premiered in Japan on November 19, 2016. Shortly after, an anime web series was announced, which is a recut of the film adaptation consisting of twelve 10-minute episodes. Website/{{Crunchyroll}} is streaming the series, while Creator/FUNimation is providing an English dub on their website.

* RetCanon: The way Nagisa is depicted with his strength maxed out is different in the anime than in the manga. In the manga, his face still has the chibi look to him, while in the anime, his entire appearance including his face becomes rougher and more realistic. This anime depiction carries over to Chapter 11 of the manga during the second time Nagisa's strength is maxed out, and is even lampshaded by Fuwa.

** During Pope Asano's game of tag, he catches Mimura while peering between two walls, making a face that looks exactly like Jack Torrance in the infamous "Here's Johnny!" scene from ''Film/TheShining''.

''Koro-Sensei Quest!'' (殺せんせーQ! ''Koro-Sensei Q!'', also known as ''Koro-Q!'' or ''Koro Teacher Quest'') is a non-canonical SpinOff of ''Manga/AssassinationClassroom'', authored by Kizuku Watanabe and Jou Aoto, and serialized in ''[[Magazine/ShonenJump Saikyou Jump]]''.

* BlobMonster: Fitting for the RPGMechanicsVerse nature of this series, such monsters exist. However, they got unusually strong by LevelGrinding off Class 3-E. We also see super fast ''Mach Slimes'' that can dodge anything, though Koro-sensei is so fast he embarrasses most of them into retiring.

** Inverted, as Class 3-E are so useless that slimes farm ''them'' for experience points.

** The very first time that the watcher sees Nagisa's random bug in action, his figure resembles Kenshiro from ''Manga/FistOfTheNorthStar''.
** When Koro-sensei says he want to fight someone on his level, [[Manga/DragonBall he dresses up as Goku in the manga and anime, while his clones dresses up as Krillin in anime only.]]

* AdaptationalJobChange:
** Aguri Yukimura was a teacher and a scientist in the original continuity, but here she's a career consultant at the Temple of Trades, and assists the hero that would later become Koro-sensei in finding his new calling.

** When Class 3-E finally reached Koro-sensei in his lair, they're greeted by a chorus of Koro-sensei singing "Tabidachi no Uta" (the insert song in the penultimate episode of the main series), celebrating Koro-sensei's "graduation" (i.e. [[spoiler:him getting fired from the Academy]]).

* ThereWasADoor: Itona introduces himself to Class 3-E by crashing into the classroom's back wall -- ''twice''. Later, Asano also enters the classroom by crashing through the window, [[HypocriticalHumor prompting Itona to scold him and ask if he's ever heard of a door]].

* AscendedExtra: Because of the more comedic tone, characters used more for comic relief in the main series like MetaGuy Fuwa and TheComicallySerious Itona get more major roles here.

* DiegeticSoundtrackUsage: Takebayashi sang the second ending of the second season of ''Assassination Classroom'', "Mata Kimi Ni Aeru Hi", at the end of Episode 10. What's more, the English dub actually had him sing it in English, when the dub of ''Assassination Classroom'' never had any of the themes adapted.

** Asano Jr. and the Big Five are now {{Paladin}}s working under the Pope, instead of being students.

* StealthPun: Possibly unintentional, but Koro-sensei sings ''Tabidachi no Uta'' while going at mach speed in the final episode. [[spoiler:[[https://twitter.com/soymilkpudding/status/846907620657053696 A Chorus-sensei.]] ]]

* ThereWasADoor: Itona introduces himself to Class 3-E by crashing into the classroom's back wall -- ''twice''. Later, Asano also enters the classroom by crashing through the window, [[HypocriticalHumor prompting Itona to scold him and tell him to use the door]].

'''There are unmarked spoilers for ''Manga/AssassinationClassroom'' on this page, since the premise of ''Koro-Q!'' assumes you are familiar with the main series' story and plot. Administrivia/YouHaveBeenWarned!'''

* ValentinesDayEpisode: The first half of Episode 10 is set on Valentine's Day, and has the girls in Class 3-E give chocolates to the boys. Unfortunately, Irina laced the girls' chocolates with compounds that turn whoever eats it into TechnicallyLivingZombies that desperately crave for more chocolate.
* VictoryIsBoring: In this continuity, Koro-sensei used to be a hero until he reached his max level, and so decided to become a Demon King to spice up his career. Too bad for him, he was so strong that even that position didn't give him much excitement until he decided to train warriors to become strong enough to beat him.

** The insert song "Moonlight" (月光) from Season 2 Episode 16, which plays during Aguri's death scene in the original continuity, is played in ''Koro-Q!'' as Koro-sensei laments to Aguri about his boredom as the demon king. Appropriately enough, in both cases, the event inspires him to take a teaching job.

Website/{{Crunchyroll}} is streaming the series, while Creator/FUNimation is providing an English dub on their website.

* CastFromHitPoints: Ritsu's magic consumes a lot of HP Sso she replenishes it [[EatingMachine eating]] [[BigEater a lot]].

** Due to it being heavily influenced by the ''VideoGame/DragonQuest'' series, there's a lot of references here and there that are ''very'' obvious, such as the use of monsters (which are more directly referenced in the manga, instead of using Kurudons like the anime does), and the reason of why Koro-sensei became the Demon King, as he simply switched jobs at the Temple of Trades, an expy of All-trades Abbey.

** Part of the ending theme's visuals is a short parody of ''VideoGame/TaikoNoTatsujin'', as a nod to Creator/BandaiNamcoEntertainment, who made a couple of games based on the main series for the UsefulNote/Nintendo3DS.

* SkewedPriorities: When Takaoka kidnaps Nagisa in order to force Class E to give up Koro-sensei, Kaede is more concerned about how they also took the [[TradeMarkFavoriteFood pudding]] Nagisa was carrying.

* AdaptationSpeciesChange: Koro-sensei, instead of being an artificial monster (who was originally a human), is now a demon king (who was ''also'' originally a human).

* GratuitousEnglish: Impostor Terasaka always speaks in perfect English.

It received an anime film adaptation (also animated by Lerche) as a companion for the ''Assassination Classroom: 365 Days'' compilation film, which premiered in Japan on November 19, 2016. Shortly after, an anime web series was announced, which is a recut of the film adaptation consisting of 12 10-minute episodes. Website/{{Crunchyroll}} is streaming the series, while Creator/FUNimation is providing an English Dub on their website.

* AdaptationSpeciesChange: Koro-sensei, instead of being an artificial monster (who was originally a human), is now a demon.
* AdaptationalSexuality: Yada goes from having a crush on Kataoka to willingly engaging with the guys on Valentine's day, though it's implied she's just being nice, but also seems distraught when Takebayashi resists her charms.

* ArtShift: Aside from the show itself being more chibi, this happens quite a bit. For instance, Nagisa's transformation due to his bug turns him into a super-buff, tall and detailed dude almost outta {{Manga/Jojo|sBizarreAdventure}}. Fanservicey scenes such [[MakesJustAsMuchSenseInContext as the skits of Irina being whipped in her underwear by her child Kunudon]], a picture of a Succubus in episode 2 and Irina's introduction as a HotWitch have the show return to the original animation. [[spoiler:The real Terasaka's return stands out too, being animated like the original series and designed like Manga/{{Berserk}}'s Guts, and remains like that even when shown in the group shots, making him stand out when he's twice the size of the others.]]

* AttractiveBentGender: Crossdressing variant. When the rescue party finds Nagisa all dressed up as a girl in episode 9, they almost unanimously agree that Nagisa looks really cute.

** Fuwa gives more jabs in ''Koro-Q!'' than she ever did in the main series. For example, during episode 6, when Koro-sensei calls Shiro by his real name, she calls out for "spoilers"; she then later states that the gardening segment from the same episode was for Isogai.

* {{Crossover}}: Neuro and Yako from ''Manga/MajinTanteiNougamiNeuro'' appear in episode 11, the latter appearing in the eyecatch and after the end credits.

* ADayInTheLimelight: Takebayashi (who got his story cut out in the main series's anime adaptation) gets his time to shine in episode 10 of this SpinOff.

* DiegeticSoundtrackUsage: Takebayashi sang the second ending of the second season of ''Assassination Classroom'', "Mata Kimi Ni Aeru Hi", at the end of episode 10. What's more, the English dub actually had him sing it in English, when the dub of ''Assassination Classroom'' never had any of the themes adapted.

** The opening as of episode 7, and the ending as of episode 8 added Ritsu and Itona, and Irina changed her look.

* FreakyFridayFlip: Happens in episode 8 to class 3-E, when they switch bodies, minds, and their bugs went along with them. For some reason Isogai's bug still works on his body. They manage to switch back by the end of the episode, but Koro-sensei and one of the slimes switched.
* GoodBadBugs: InUniverse. Everyone in 3-E has a glitch (called "bugs" in the English dub), but Koro-Sensei tries to show them [[HeartIsAnAwesomePower the advantages of their glitches]], as a way to defeat him.
** Nagisa's bug causes random effects when he summons his will to act. The first time it happens, it gives him 99999 strength. The next causes Kaede to turn into a green clone of Koro-sensei. The last one [[spoiler:sends the entire class and Koro-sensei back to episode 1 as a NewGamePlus.]]

* HypocriticalHumor: When Asano enters in the classroom with his horse, he went through the window, and Itona asks if Asano ever heard of a door. When he himself, had entered the classroom through the wall, twice. Lampshaded by Maehara.

** Takebayashi's first line is also about his liking 2-D girls, followed by someone asking him if he wants that to be his first line.

** Every time Hana appears, she's eating something.
