''Manga/SayonaraZetsubouSensei'' is a twisted, funny, manga/anime about a [[DysfunctionJunction class full of weird students]] with a matching teacher, the titular Mr. Despair. Interestingly, every single character has a PunnyName referring to the [[MeaningfulName character's personalities]]. And there are a lot of characters.
->'''Note:''' Due to the episodic nature of the series, spoilers are unnecessary for the following tropes. Though the last few Manga chapters contain some serious spoilers so best not to read spoilers until you've read the Manga to the end.

!!The Itoshiki Family
The Itoshiki family is a powerful clan dominating over their native Kuraizawa, Shinshuu Prefecture (a NoCommunitiesWereHarmed version of Karuizawa, Nagano Prefecture), whose name (糸色) can be compressed to read as 絶 -- "zetsu" ("beyond" or "to sever") -- which often serves to undo the specific meaning of each member's names... thus one can re-interpret "Itoshiki Household" (糸色家) as 絶家 -- "zekke" ("extinct family").

[[folder:Itoshiki Nozomu]]
!!Itoshiki Nozomu (糸色 望)
!!!'''Voiced by:''' Creator/HiroshiKamiya
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/szs_nozomu_itoshiki_2445.jpg]]

Main male character of the series, fourth (and youngest male) of the five Itoshiki siblings, and the [[NietzscheWannabe manic-depressive]], [[DrivenToSuicide suicidal]] homeroom teacher of Class 2-He.
----
* ApatheticTeacher: The only time he's not apathetic towards his students is when he rants at length about his latest excuses to commit suicide.
* AttentionWhore: Apparently the motivation for every outrageous action he does.
* BetterToDieThanBeKilled: Nonfatal comedic version. Although he often attempts to [[DrivenToSuicide commit suicide]] very often, the times he actually gets closest to death are when someone else gets involved, mainly Kafuka, to stop his attempt and thus the second catchphrase makes sense with this in mind.
* CharacterCatchphrase: Most common is...
-->"I'm in despair! (''Subject of Nozomu's rant'') has left me in despair!!!"\\
"What if I had died?!"
* ChewingTheScenery: Nozomu's rants. Most tend to ignore it.
-->'''Nozomu:''' I'm going to hang myself.
-->'''Chiri:''' Go ahead, see if I care.
-->*Chiri sees Matoi also about to hang herself*
-->'''Chiri:''' You need not do as he does.
%%* ChickMagnet
* CluelessChickMagnet: All he does is rant about whatever is currently bothering him, somehow attracting the attention of almost all of his female students in the process. Even after he's earned their attention, he almost never seems to realize their feelings for him.
* DeathSeeker: Averted - for all his suicidal ravings, he's not that serious about his suicide threats, especially if someone else (mostly [[CuteAndPsycho Kafuka]]) almost gets him KilledOffForReal.
* DespairEventHorizon: He passes it at the drop of a hat, to the point where announcing he has is his catchphrase.
%%* DrivenToSuicide OnceAnEpisode: In fact, the poster boy for the former.
%%* TheEeyore
%%* {{Emo}}
* EvenTheGuysWantHim: Several male characters show an interest in him, primarily [[AmbiguouslyGay Jun]].
* EyesAlwaysAverted: At one point, he believes he can escape [[ItMakesSenseInContext arranged marriage by eye contact]], as he is a master of avoiding eye contact. Probably counts as the neurological or psychological disorder variant.
* FlatWhat: His standard reaction to Kafuka's improbable explanations.
%%* HotBlooded: Of the negative variant.
* HotTeacher: Which may explain the legion of [[ChickMagnet female]] ([[EvenTheGuysWantHim and one male]]) students falling for him.
* IronicName: "Nozomu" means "to hope", which is exactly what he is ''not'' doing.
* JerkWithAHeartOfGold: A snarky, apathetic teacher he may be, who is also prone to breakdowns and occasionally dying (and coming back to life), but nevertheless he shows genuine concern for his students -- well, some of them, anyways.
** JerkWithAHeartOfJerk: On the other hand, he couldn't care less about his "secondary students", which is played for laughs.
* LargeHam: A family trait, though he probably tops his siblings.
* LimitedWardrobe: Always wears a kimono and hakama: even when not in his usual clothing it is generally something retro and Japanese. Sometimes subverted, however -- as his students found out, he wears casual western clothing in his native Kuraizawa.
%%* MadeOfIron
* MarryThemAll: [[spoiler: His ultimate decision at the end of the manga. Yes, this includes [[NoYay Meru]] and [[GayOption Jun]].]]
* MotiveRant: Ruthlessly parodied, as he rants every episode about his latest reason to commit suicide.
* MrFanservice: A parody. He's a [[ReluctantFanserviceGirl Reluctant Fanservice Guy]], and apparently, every character attracted to him (there are a few) sees him as a different stereotype or archetype, mostly because the class's ideas of what is generally considered attractive are cobbled together from shoujo anime and badly written manga. It is occasionally played straight, though.
* NighInvulnerability: Survived ''every'' threat on his life, self-inflicted or otherwise -- he was hanged, stabbed, bludgeoned, exposed to carbon-monoxide poisoning, got ran over by a runaway streetcar, attempted to drown himself (or drink himself to death) in a bowl of Dom Perignon, overdosed on OTC medications, and even had his name written on the Manga/DeathNote. Even when he ''does'' die, it doesn't ever stick, much to his consternation. Incidentally, popping out of his coffin at his own funeral to tell everybody to stop blaming themselves for his death inadvertently spared him (and Matoi) the inconvenience of having to survive cremation.
* NotDistractedByTheSexy: In one chapter of the manga, [[OnlySaneMan Nami]] does a very deliberate PantyShot in order to get his attention. He doesn't care.
* ObliviousToLove: Despite all of his female students having massive crushes on him, he's barely aware of their feelings at all. It seems to be more of a case of him just not caring rather than actually not understanding it.
* OldMaid: A male example. His family is constantly trying to marry him off before his 25th birthday.
* OnlySaneMan: At the end of the day, and in stark contrast to most of his students, Nozomu is actually a sane, rational man whose pessimistic streak stems mostly from his high school days as an accidental member of the "Negative Club".
* PlagueOfGoodFortune: His legion of admirers from both sexes.
* PunnyName: His name, written horizontally and compressed, can be read as 絶望 -- "zetsubou" ("despair"), befitting his nature. Meanwhile, "itoshiki-sensei" (his title as a teacher) can be read as 愛しき先生, meaning "beloved teacher", which seems to allude to all the girls in his class who are attracted to him.
%%* RedOniBlueOni: The blue to Kafuka's red.
* StockholmSyndrome: How he got his negative streak, by accidentally signing up for the "Negative Club" back in his high school days.
%%* StrawNihilist
%%* TallDarkAndHandsome
%%* TallDarkAndSnarky
* TeacherStudentRomance: [[spoiler: Only for Kafuka, although it turns out that he married everyone of his students instead and that [[TheLostLenore Kafuka]] was DeadAllAlong]].
%%* TsurimeEyes
* UnwantedHarem: The few times he recognizes his harem, he's clearly more annoyed by it than anything.

[[folder:Itoshiki Rin]]
!!Itoshiki Rin (糸色 倫)
!!!'''Voiced by:''' Creator/AkikoYajima
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/szs_rin_itoshiki_6820.jpg]]

Youngest of the five Itoshiki siblings (and the only female), an ikebana master with a major complex towards the AlternateCharacterReading of her own name. She eventually becomes a student in 2-He, under the tutelage of her immediate older brother Nozomu.
----
* BerserkButton: Spell out "zetsurin" and she will scream for a katana in no time.
* BitchInSheepsClothing: Rin will often do generous things for the purpose of laughing at people, such as giving [[CharlieAndTheChocolateParody golden tickets]] to [[NerdsAreVirgins virgin nerds]] with no girlfriends to give them chocolate.
%%* EeriePaleSkinnedBrunette
* HimeCut: She's an {{Ojou}} with straight full bangs, bra strap length sidelocks, and waist length wavy hair.
%%* LargeHam: A family trait.
* {{Ojou}}: She fits both the traditional (style of dress, an ikebana master) and snobby (enters Nozomu's school just to feel what it's like being a commoner, buys off all surrounding property and evicting their residents) variants.
* PunnyName: Her name, written horizontally and compressed, can be read as 絶倫 -- "zetsurin" ("peerless"), which at first glance refers to her expertise at many skills (which involves her getting random odd jobs out of nowhere), but is also ([[BerserkButton much to her ire]]) a slang for sexual prowess.
* ScrewTheRulesIHaveMoney: One segment has her buying the entire neighborhood she lives in, so she can move around without fear of Chiri checking on her every hour.
* UnfortunateNames: The combination of the two kanjis in "Itoshiki" makes Rin's full name be misread as "Zetsurin," which means "peerless in bed". She ''badly'' wants to get married in order to lose her maiden surname and consequentially her sexually-suggestive nickname. However, her family's power and esteem add an unfortunate wrinkle: among the Japanese upper-classes, a groom of lower standing is often legally adopted and takes the ''bride's'' surname instead, and there are few families for Rin to "marry up" into.

!!!'''Voiced by:''' Creator/AkikoYajima
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/szs_majiru_itoshiki_5979.png]]

Only son of Enishi, (missing) eldest brother of the Itoshiki siblings, who lives with his youngest uncle, Nozomu.
----
%%* AdorablyPrecociousChild
* BreakTheCutie: PlayedForLaughs as a RunningGag -- he is very easily (and frequently) traumatized by Nozomu's students' antics.
* FreeRangeChildren: Is pretty much this thanks to ParentalAbandonment. There's references in the manga to the girls in the class taking turns raising him, but other than that, he's pretty much on his own, as Nozomu isn't really parent material.
* InnocentProdigy: Comes across as more mature and down-to-earth than his uncle, but can also act in a way fitting his age. There's also some situations that might be either this or PingPongNaivete, like having a crush on a net idol and commenting on her breasts, while also thinking that [[DeliveryStork storks deliver babies]].
* LimitedWardrobe: Just like his uncle, he frequently wears a kimono and hakama.
* MeetCute: With Meru, while she's [[CrossesTheLineTwice running away from a pedophile who just kidnapped her]].
%%* MouthyKid: Has some shades of this.
%%* {{Nephewism}}
* ParentalAbandonment: Which explains why he has to live with Nozomu.
* PrecociousCrush: Hinted at, with his relationship to Kiri.
* PrettyFreeloader: A rare male variant, to his uncle Nozomu.
* PunnyName: His name, written horizontally and compressed, can be read as 絶交 -- "zekkou" ("breach in a relationship"), hinting to his broken family and having to stay with his youngest uncle.
%%* TsurimeEyes
* UncannyFamilyResemblance: He looks like a young Nozomu.

!!!'''Voiced by:''' Creator/HiroshiKamiya
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/szs_mikoto_itoshiki_6964.png]]

Third of the Itoshiki siblings, Nozomu's immediate older brother, and a doctor running his own private clinic.
----
%%* EeriePaleSkinnedBrunette
* {{Headdesk}}: His head repeatedly meets the wall every time his nickname "Dr. Death" gets mentioned.
%%* HospitalHottie
%%* LargeHam: A family trait, though less so than his siblings.
* MrExposition: Share this status with Chie-sensei [[spoiler:in the last chapters, explaining the circumstance of Kafuka's HiveMind in class 2-He and Nozomu's reason for persisting in his efforts to teach the misfits. Doubles as SecretKeeper.]]
* NamesToRunAwayFromReallyFast: According to him, the embarrassing AlternateCharacterReading of his own name -- "death" -- is what's keeping most prospective patients away from his clinic.
* OnlySaneMan: He's probably the most composed and rational of his siblings... apart from his hatred of his nickname.
* PunnyName: His name, written horizontally and compressed, can be read as 絶命 -- "zetsumei" ("death") -- not a good name for someone of his profession, especially if nicknamed [[NamesToRunAwayFromReallyFast "Zetsumei-sensei" ("Dr. Death")]].
%%* TallDarkAndHandsome
* UncannyFamilyResemblance: With Nozomu -- no wonder Kafuka was confused when she saw him for the first time. Sharing the [[Creator/HiroshiKamiya same voice actor]] also reinforces this.

!!!'''Voiced by:''' Creator/TakehitoKoyasu

Second of the Itoshiki siblings (older brother to Mikoto, Nozomu and Rin) and a surrealist artist.
----
* {{Cloudcuckoolander}}: He is even married to ''the stain on the wall of his house''.
%%* LargeHam: A family trait.
%%* MadArtist: Sort of.
%%* PermaStubble
* PunnyName: His name, written horizontally and compressed, can be read as 絶景 -- "zekkei" ("superb scenery"), although his works are not so much superb as they are utterly weird.
* StrongFamilyResemblance: Give him a hair cut and a shave and he's a slightly older Nozomu.
[[/folder]]

[[folder:Itoshiki Enishi]]
!!Itoshiki Enishi(糸色 縁)
The unseen older brother of Kei, Mikoto, Nozomu and Rin, as well as Majiru's father.
----
* DisappearedDad: A case where [[spoiler: he's ''forced'' to become one. Apparently, his love for his son was so strong he can't even go near him without the mask and armor restraining it.]]
* TheGhost: He's mentioned several times, and actually left a note in one chapter, which read "I searched everywhere, and couldn't find you guys." [[spoiler:He finally appears and meets up with his family in the last volume.]]
-->'''Majiru:''' Dad was here?!
* HeWhoMustNotBeSeen: [[spoiler:Yet, he appears in the final volume.]]

* {{Irony}}: [[spoiler:He was previously a divorce lawyer, but is now a marriage counsellor... albeit for posthumous couples.]]
* NoodleIncident: His name means "Disinherited", after all, and we never got to see what caused that. [[spoiler:Even after he appears in the final volume.]]
* PapaWolf: He once beat up every other contestant to be Santa Claus of the Year, so that he could deliver a gift to Majiru.
* PunnyName: His name, written horizontally and compressed, becomes 絶縁 -- "zetsuen" ("disinherited") -- which may hint at his whereabouts.
* UncannyFamilyResemblance: It's stated that he resembles Nozomu. [[spoiler:His appearance in the last volume finally lets us see this.]]

----
* HappinessInSlavery: Due to some crazy mix up, [[ItMakesSenseInContext it turns out that Tokita is the true heir of the Itoshiki family and the family are actually his servants]]. He uses his new prestige to order the servants to revert back to the status quo because he likes being a butler.

%%* HeWhoMustNotBeSeen
* ItAmusedMe: The reason why he named his children with all those PunnyName.

!!Class 2-He
Nozomu's high school homeroom class. The "He" (へ in Hiragana) signifies that it is the sixth second-year section based on the [[http://en.wikipedia.org/wiki/Iroha iroha]] order (in modern nomenclatures this would be called Class 2-6 or 2-F). The class is said to have 32 students, though so far only 23 have been named.

All students in this folder are in Nozomu's class unless otherwise noted. Nozomu's younger sister Rin is also a student in this class.

!!!'''Voiced by:''' Creator/AiNonaka
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/szs_kafuka_fuura_6072.jpg]]

The creepily optimistic main female lead, who often gives an extremely implausible positive side to anything Nozomu is currently ranting on.
----
* AGodAmI: Subtle, but it exists. Her goal in life is to be a God (her other goal is to be an alien). There's also an instance where she practically psychologically ''tortures and brainwashes''[[note]]she entirely isolates them in jail and sets herself up as a messianic figure who can release them[[/note]] Nozomu, Nami (who turns out to have a quite large ego herself), and several others into thinking that she's a Goddess. [[spoiler:In the end of the manga, she's succeeded. [[ResurrectiveImmortality In a way...]]]]
* AmbiguouslyEvil: Is she fully aware of her... "actions" and her status as a NightmareFuelStationAttendant, or is she just an innocent girl? The ending doesn't really shed any light on this. [[spoiler:On the one hand, she saved the entire main cast from death and continues to prevent them from committing suicide while at the same time brainwashing them into a hive mind.]]
%%How?* AxCrazy: More than Chiri. Yes, more than Chiri.
* BewareTheNiceOnes:
-->*Meru stares through Kafuka's eyes*\\
'''[[{{Troll}} Meru]] (monologue):''' This girl's scary!
%%* BewareTheSillyOnes
* BodySurf: [[spoiler:Her spirit has been alternately possessing different students from the class since the beginning of the series. Only the recipients of Kafuka's organs or blood can see her; the rest will only see her host acting out of character.]]
* CharacterCatchphrase:
-->"How could (''subject of Nozomu's rant'') be possible? It's just (''highly implausible theory'')!"
* {{Cloudcuckoolander}}: Believes that, one day, the Pororocoaians will descent upon the Earth, among many other things.
* TheCloudcuckoolanderWasRight: When she and Itoshiki are trying to lure Komori Kiri out of her home, Kafuka remarks that she must be a ghost that lives in buildings and brings it and its inhabitants good luck. When she is eventually coaxed out of the house, it's later revealed that it collapsed and [[WhatHappenedToTheMouse killed her father in the process]]. Later, the very same thing happened to the school after Komori left it.
* CorruptTheCutie: As the series went on, her psychotic tendencies and violent outbursts became more frequent and extreme.
* CuteAndPsycho: While she's fairly stable right now, her classmates and friends fear the day she snaps and murders the entire class, which they predict isn't too long away.
* DarkAndTroubledPast: "Dark and troubled" doesn't even begin to describe it - first her parents betrothed her to someone, then her mother was possessed by a spirit and had Kafuka MercyKill her. This left Kafuka alone to face the brunt of her severely mentally-ill father's antics, [[spoiler:which culminated in him taking out a life insurance policy on her before murdering her by pushing her into traffic and disappearing with the payout.]] Youch.
* DeadAllAlong: [[spoiler:In the second to last chapter it's revealed that she died long ago and donated her organs which made their way to all the other girls in the class. This means that she was able to possess each girl and every time we saw her it was just one of the other girls and the other girls saw her as Kafuka. In the episode that introduces Meru it was Abiru hence why she had a bandage on her arm. And in the last chapter of the manga, when she is seen on a wedding dress it was actually Kudou hence why she had green eyes and a cross necklace. Yes, it's been foreshadowed from the beginning--including in the anime [=OPs=].]]
* DeadlyEuphemism: Champion of it.
-->You're not trying to hang yourself -- you're just trying to grow taller!
* DisappearedDad: Her father, [[spoiler:who took out life insurance on her and threw her in front of a moving car,]] is nowhere to be found, and is implied to have fled the country.
%%* DissonantSerenity
* FirstGirlWins: Well, sort of. [[spoiler:She's the ONLY one that Nozomu loves (at least in the manga, which is expressly stated to be just one of many possible endings) after all. From his perspective, he's always been married to her.]]
* {{Foil}}: To Nozomu, who is outwardly suicidal and depressed about ''everything'', but is actually [[OnlySaneMan pretty normal underneath it all]]. Meanwhile, Kafuka is all smiles all the time, when [[CuteAndPsycho actually]]...
* {{Foreshadowing}}: [[spoiler: To her death. Rewatching the series with the fact that Kafuka has been dead for a long time makes it very evident that Kumeta was planning the ending for a long time.]]
* GodhoodSeeker: One of her goals.
* HilariouslyAbusiveChildhood: Her schizophrenic father tried to commit suicide and/or kill her several times before, and her mother was once possessed by an evil spirit. Whom she had to kill by beating her to death with a cross. Among other horrible things, she has a fiance - and it's implied it was a forced marriage arranged by her one dead parent and other schizophrenic parent. [[spoiler: [[{{Foreshadowing}} It's implied that]] her father took out a huge insurance on her, and then threw her directly in front of a moving car.]]
* InnocentFanserviceGirl: Played with; it's implied she's doing it intentionally, just because [[TheGadfly she can]], or to get Nozomu's attention.
* InsaneTrollLogic: All the time. It's both [[NightmareFuel pants-wettingly disturbing]] and [[{{Moe}} freaking adorable]]. Like how if she fed herself to a lion, she'd become God, even though Buddhism has no God, and Shintoism has multiple Gods, meaning there is no "God". Or how one day, when all is beautiful and peaceful on a summer's day, the Pororocoians shall descent upon the Earth.
* IronicNickname: Played straight and subverted. Her pen name, "Kafuka Fuura", comes from Franz Kafka, the author of Metamorphosis, her favorite story. [[spoiler: One morning, when Kafuka Fuura woke up, she had become Kobushi Abiru, Kitsu Chiri, Matoi Tsunetsuki...]]
* InsuranceMotivatedMurder: [[spoiler:She's revealed to have been a victim of this at the hands of her schizophrenic father, who took out a claim on her before pushing her into oncoming traffic and presumably fleeing the country with the payout.]]
* KillTheCutie: [[spoiler:She's actually been dead for a very long time. The problem is that nobody's noticed.]]
* TheLostLenore: [[spoiler: To Nozomu since despite being the only one he was romantically in love with, she died before the series even begins. Thankfully all of [[StrongFamilyResemblance his children resembles her]] via her possessing all the students he actually married]].
* MeaningfulRename: There's a reason for Kafuka's pen name. [[spoiler: The girls who received her organs, and thus were possessed by her because of this, only knew that their donor was "a teen from the Tokyo area". This is why their collective consciousness, being unable to accept the impersonality of this, gave her a name after the author of Kafuka's favorite story: ''Literature/TheMetamorphosis''.]]
-->[[spoiler: One morning, when Kafuka Fuura woke up, she had become...]]
* {{Miko}}: Is one when volunteering at her local Shinto shrine. She herself is a syncretic Buddhist/Shintoist, like many Japanese people.
* MsFanservice: An energetic, adorable young woman in a skirt that's only mostly [[MagicSkirt magic]]? You don't say.
* NamedAfterSomebodyFamous: Her (pen) name sounds similar to Creator/FranzKafka. Also, speculation has it that her real name, based on several hints throughout the series, is "An Akagi", referring to ''Literature/AnneOfGreenGables'' (Japanese title ''Anime/AkageNoAnne'', "Red-haired Anne").
* TheNicknamer: Once called Nozomu "Momoiro Kakaricho" ("Pink Superintendent"), after she caught him trying to hang himself on a sakura tree.
* NightmareFuelStationAttendant: Once drew a very detailed picture of a very detailed car accident and often says highly disturbing things - usually accidentally - that frightens her classmates. In several scenes, it becomes glaringly apparent that all of her classmates - including the musclebound illegal immigrant, knife-wielding ControlFreak and TheBigGirl - are all incredibly afraid of her, and they all fear the day she loses her mind and kills each and every single one of them.
* NiceGirl: Despite the madness that happens around her, a world that has lost its mind, and her one true love offing himself every other [[ButForMeItWasTuesday weekend]], she is still optimistic, and is good at gathering people for a cause. [[spoiler: After she died and being able now to possess her classmates, she activated some sort of genetic code in the blood and organs she left, stopping them from killing themselves. As Chie puts it, "She's like a mother to the entire class."]]
* ObfuscatingStupidity: At first, she looks like TheDitz with a few {{Cloudcuckoolander}} qualities mixed in. In reality, she uses this to cover up her DarkAndTroubledPast.
* PaperTalisman: Is also a syncretic Buddhist/Shintoist, and believes that if she feeds herself to a lion, she'll become Buddha. Or that's the mental disturbance talking.
** Kafuka overdoes it when she doesn't want Kiri to leave her house.
** She also [[http://img215.imageshack.us/img215/1325/szsflvsnapshot030820101.jpg uses the tags]] during the MagicalGirl spoof as a shoutout to [[Franchise/SailorMoon Rei]].
* ThePollyanna: She's still cheerful and optimistic [[spoiler: even after death]].
%%* RedOniBlueOni: The red to Nozomu's blue.
* ShipperOnDeck: Kafuka actually ships virtually ''[[MarryThemAll the entire female half of the class]]'' (or at least the 12 main girls) with Nozomu, even though ''she also wants him too''. Makes sense considering [[spoiler:all of them are actually her ''host bodies'' as revealed in the final three chapters]].
** The only time she ever got jealous (''"MILF's in schoolgirl uniforms are lame!"'') at all was when Nozomu was smitten by the twenty-something (and extremely curvaceous) Chie wearing a high school uniform which was apparently a tight fit for her. Makes sense in that [[spoiler:Chie, being clearly older, is probably not one of the donee-recipients of Kafuka's blood and/or organs, and thus not one of Kafuka's host bodies]].
* SomeoneToRememberHimBy: [[spoiler: A female example. While her friends eventually forget that she ever existed, she has numerous children who look exactly like her, and are just as optimistic and friendly.]]
* StepfordSmiler: This gets bigger and bigger every episode, to the point where it seems like Kafuka is always on the verge of a complete and utter breakdown. [[BlackComedy She is]]. By the end, she's basically a walking smile hiding an all-consuming void of agony, and it's [[CrossesTheLineTwice hilarious]].
* WideEyedIdealist: Ridiculously so. She even provides the page image.
* WordSaladLyrics: Every song she sings has random and nonsensical lyrics. [[https://www.youtube.com/watch?v=372PCB4pSZ8 Her image song]] is not an exception, although it's probably meant to reflect her [[{{Cloudcuckoolander}} personality]].

* CuteClumsyGirl: She tries to be one at one point. [[LethalKlutz It ended with the school on fire and Itoshiki in the hospital]] from a CrashIntoHello stabbing.
* {{Expy}}: She basically inherited parts of [[Manga/KatteNiKaizo Umi's deranged behavior]].
%%* TheFriendNobodyLikes
* GameFace: She's usually pretty cute, but when she turns into a {{gonk}}, people die !
%%* NeatFreak
* PunnyName: ''Four'' alternate readings, to be exact. Her full name (in Japanese order) can be read as きっちり -- "kicchiri" ("precise"), referring to her ObsessivelyOrganized tendancies. Her given name can be compressed to form the first kanji of 埋める -- "umeru" ("to bury"), which explains her [[ShovelStrike spade]], or used as the first two kanji for 千里眼 -- "senrigan" ("clairvoyance"), explaining her ThirdEye. Finally, her given name can be an onomatopeia, "chirichiri" ("frizzy"), as her hair is actually frizzy, and she has to frequently iron it out to give it a perfectly straight look.
%%* SerialKiller
* SheCleansUpNicely: In the last few chapters of the manga, she's inexplicably in a [[CostumePorn gorgeous dress]] and looks like she just gained two cup sizes, and she's got a [[WhenSheSmiles cute smile planted on her face]].
** Parodied in an earlier chapter, where the girls are used as metaphors as seeds. She ends up burying the entire class [[TheyKilledKennyAgain who die]], but she grows into a bishoujo protagonist, complete with SomethingAboutARose and BishieSparkles. A big TakeThat, of course.
* ShotgunWedding: Insists on this to Nozomu after accidentally sleeping together in a clinic bed (though it is Chiri herself who rolls through the curtains into Nozomu's side).
%%* SiblingYinYang: With the extremely messy Tane.
* ShovelStrike: Primarily uses a spade; sometimes, [[FlechetteStorm a bunch of throwing knives]].

* SupportingLeader: But expect everything she leads quickly turns violent one way or another.
* TerribleArtist: One segment shows her with bad drawing skills. Ironically, [[Creator/MarinaInoue her voice actress]] is a good artist who even has her own Pixiv page.
* TheBGrade: Subverted; it seems like she's annoyed when she gets four 5s and a 4, but she'd rather get five grade 4s than have them unequal.
* TheDeterminator: Among other things, she once singlehandedly saved Earth from an alien invasion when transformed into a giantess. Lampshaded in that an AlternateUniverse version of her is a MagicalGirl.

* TsurimeEyes: [[https://static.tvtropes.org/pmwiki/pub/images/CHIRI_01_4298.jpg Occasionally sports these.]]
* VictoriasSecretCompartment: Her bra (which is a few cups too large for her actual bust size) serves as this, concealing her throwing knives.

!!!'''Voiced by:''' Creator/YukoGoto
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/szs_abiru_kobushi_6488.jpg]]

A student who's frequently wrapped in bandages. Contrary to in-series popular belief, she is not a victim of domestic violence; rather, her injuries are caused by irate animals victimized by her tail fetish.
----
* AnimalsHateHer: She's hated by all animals and is constantly being beaten up by them. Because of the RuleOfFunny, she's loved by the animals she cares for at the zoo.
* AttentionWhore: Once admitted to wearing her bandages even when not injured, just for the sake of attention.
* BestialityIsDepraved: The revelation that she pesters animals into abusing her is considered almost as bad as the alleged parental abuse that she suffers.
* BoobsAndButtPose: Here and there.
* CollectorOfTheStrange: Her collection of mounted animal tails.
* CovertPervert: She turns out to be a massive sadomasochist, so she enrages animals at the zoo to beat her up. In other words, she has zoomasochism. It's played for both laughs and {{Squick}}. [[BlackComedy Mostly laughs]].
* CutHimselfShaving: Subverted -- she's frequently thought to be a victim of domestic violence; in reality, her injuries are caused by animals whose tails she pulls.
* DarkAndTroubledPast: [[spoiler: She attempted to kill herself by launching herself off of a balcony before the series started.]]
* DeadpanSnarker: Very much so. She always has a bored, nondescript expression on her face, and although she drops in and out of focus - as is expected with a cast this large, even if she usually is in focus - she has many a good snark. Her first - and establishing - is when Kotonon says she's never been called fat before in her life, Abiru's only response is, "Really, never?".
* DualityMotif: Her green left eye (a result of a corneal transplant), which is frequently covered by an eye patch; the other is brown. In one chapter in Volume 8, she indicates that it was transplanted from a victim of a car accident, and even claims she can see [[EyeRemember the last thing the donor saw]] -- the license plate of the killer car. [[spoiler:The eye happens to be from one An Akagi who is better known as Fuura Kafuka. She also sees the other girls as Kafuka through her transplanted eye, foreshadowing the reveal that Kafuka is possessing the girls in Nozomu's class.]]
* EmotionlessGirl: Except whenever talking about animal tails or alone with Nozomu.
* {{Fetish}}: Animal tails. She even has a part-time job at the zoo just to indulge her obsession, and frequently gets injured by irate animals whose tails she loves to pull. She even has walls full of mounted animal tails.
** She'll also occasionally use her bandages in bondage-y scenarios, often with Nozomu on the receiving end.
%%* InscrutableOriental
* TheKlutz: Somehow. She's poor at athletics.
* MsFanservice: This overlaps with her Bandage Babe status. Out of the entire cast, she is usually the most "shown off". She also shows a very minor example of [[HartmanHips Hartman Hips]]. Her bandages do not help.
* NotSoStoic: Whenever the subject of her {{Fetish}} pops up.
* PunnyName: Her name is derived from 拳[を]浴びる -- "kobushi (wo) abiru" ("to bathe in fists"), referring to her injuries.
* ReiAyanamiExpy: [[DownplayedTrope Downplayed]]. In a deliberate ShoutOut, she has the same bandages Rei does in the first episode of ''Anime/NeonGenesisEvangelion'', is an EmotionlessGirl, and is ''supposedly'' abused by her stern, bespectacled father. However, the similarities end there; she doesn't spend much time pondering consciousness or existence.
* TheStoic: She doesn't have much of an emotional range to her voice, and is more than happy to blend into the background...

A hikikomori accidentally scared out of her home by Nozomu and Kafuka; she has since become a resident at school and eventually a caretaker figure for Nozomu and Majiru.
----
* TheCaretaker: For Nozomu and Majiru.
* CharacterCatchphrase: "Don't open it."
%%* CoolBigSis: To Majiru.
* DarkAndTroubledPast: [[spoiler:Tried to kill herself by overdosing on an entire bottle of pills before the series starts.]]
%%* EeriePaleSkinnedBrunette
* {{Hikikomori}}: It seems her aversion to the outside world is a conscious choice; when she got cornered by Nozomu and Kafuka to attend school and when she sleepwalks, she can go outside. Though she wants to go to many places, including the sea and the meadow, she will never actually go outside as long as she has a say in it. She seems to have [[http://en.wikipedia.org/wiki/Agoraphobia agoraphobia]]--fear not of social interaction, but of open space itself.
* ITakeOffenseToThatLastOne: Call her a shut-in, call her a house fairy, and she'll only note it for a moment before dismissing it. But call her a {{NEET}}, and she will protest. After all, she has a job as a freelance computer programmer; never mistake a shut-in for a NEET just because she never goes out.
* ImprobableWeaponUser: Uses a TV.
* MsFanservice: Sometimes seen semi-clad. The manga volumes even have pictures of her in varying states of undress.
* PunnyName: Her name in Japanese order can be read as 籠もりきり -- "komorikiri" ("recluse") and, in Western order, even sounds like "{{hikikomori}}".
* TheRival: Since she and Matoi spend the most time around Nozomu, the two have the biggest rivalry for his affections.
* RunningGag: She frequently appears in the least expected of places.
* SecurityBlanket: She's rarely seen without one.
* TeacherStudentRomance: Once to Chie, ''always'' to Nozomu.

A notorious stalker who fell in love with Nozomu and has since been following him and even emulating his dress code.
----
* DeadpanSnarker: Not as much as Abiru, but she has a quite dry wit even toward Nozomu, as shown when he brought a lot of [=TVs=] that were shoddily made with reasoning that quantity is better than quality.
-->'''Matoi:''' No matter how many you make, shitty [=TVs=] are still shitty.

[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/szs_nami_hito_6870.png]]

Unlike the other girls, Nami is perfectly plain and normal...other than a long stint of playing truant, but then she showed up to school and lost even that bit of uniqueness.[[note]]Although of course, considering how dysfunctional the entire class is, missing school is still not very special.[[/note]] Ever since, she has been playing the StraightMan whether she likes it or not.
----
* ButtMonkey: Due to being the [[StraightMan "normal" girl]] in the group. Treated as this mostly by [[{{Yandere}} Chiri]] or [[DeadpanSnarker Abiru]].
* CharacterCatchphrase:
-->"Don't say 'normal'!"
-->"Sensei, you've said too much again!" (Whenever Nozomu's rants portend disastrous consequences, such as Chiri going AxCrazy again.)
* DemotedToExtra: Before the series even began; according to the character page on Website/TheOtherWiki, she was [[WhatMightHaveBeen originally intended as the female lead]].
* EveryoneOwnsAMac: She's a patron of Apple electronics; [[TruthInTelevision during the series' run they were a bit of a niche product]], meaning she's probably just making another ultimately futile attempt at looking special.
* TheGenericGirl: Much to her distress. So generic that in ''Bangaichi'' even real-life movie subtitle writer Todana Tsuko, (in)famous for her absurdly liberal translations of foreign films, had nothing special at all to say about Nami.
-->'''Tsuko:''' 'Normal' is good enough for normal!\\
'''Nami:''' [[CharacterCatchphrase Don't say 'normal'!]]
* HollywoodPudgy: In-universe, as the result of CharacterizationMarchesOn. A bit gluttonous (especially if it's ramen) and having a complex over her weight with those diet plans and pills she often mentions. Of course, since she's one of the show's main girls, she ends up as skinny as the other girls. This being ''Zetsubou Sensei'', this trait is properly mocked and lampshaded.
%%* IJustWantToBeSpecial
* NotSoAboveItAll: Is shown to cut herself, has many weight issues, and much like her teacher, repeatedly tries to off herself to gain attention. She's definitely a mentally disturbed person; it just so happens she's in a class of even more mentally disturbed people.
* ObsessedWithFood: Her later characterisation renders everything she says and does into a joke about how she's [[HollywoodPudgy fat]], and all of it has to do with fatty foods, like donuts, cakes, and sweat bread.
%%* OnlySaneMan: And does ''not'' want to be one.
* PhraseCatcher: Nozomu always replies "How normal," whenever Nami explains her behavior and/or preferences.
* PunnyName: Her name (in Japanese order) can be read as 人並み -- "hitonami" ("run-of-the-mill").
* StraightMan: According to Kafuka, she is "more normal than most people". Of course, this is subverted and PlayedForLaughs during her proper introduction in the first episode of ''Zoku'', where she claimed to have various problems no normal person would have just to garner attention and sympathy, only to be outdone by her classmates, so she threatens suicide. Of course that is the moment Itoshiki makes his appearance by attempting to ''hang himself'' from the school roof. Only Nami reacts to it though.

The resident doujin artist and yaoi fangirl with a taste for slash pairings (usually involving famous anime characters, her own teacher and some of her male classmates, but especially "Pine x Napple"), as well as a hidden athletic talent.
----
* TheAce: Not to the extend of Chiri, but still she's a star student and athletic genius without peer. The only thing that holds her back is her love for her doujin.
* AuthorAvatar: Unashamedly. She mostly exists for Kumeta to talk about pop culture and manga.
* BadassBookworm: Sort of -- she's a manga-loving nerd with incredible athletic prowess.
* ChildhoodFriends: With Chiri. She knows many things about Chiri's past (such as the circumstance of her sister's extreme hygiene problem) while Chiri trusts her to do many things perfectly when Chiri herself can't do them; [[TheAce Harumi she does just that]].
* {{Fetish}}: [[AnimalEaredHeadband Cat ears]]
* PowerLimiter: Her glasses parody the weighted clothing in fighting manga like ''Franchise/DragonBall''--they're actually extremely heavy, and prevent her from showing off her incredible athletic skill so she can make doujin instead of being pestered to join a sports club.
%%* SequentialArtist
* PunnyName: Her given name is an AlternateCharacterReading of Harumi district (晴海) in Chuo, Tokyo, the previous site of Comiket before it went big and moved to the larger Tokyo Big Sight in Ariake; her family name is a corruption of 腐女子 -- "fujoshi", a derogatory term for {{Yaoi Fangirl}}s like herself.
* SuperStrength: Harumi's "athletic talent" surpasses all reason, being more along the line of super strength.
* YaoiFangirl: Often doubles as a ShoutOut, given some of the pairings she likes to read about. Bonus for points for being a homophobe, effectively turning her into a Deconstruction of the hypocrisies of yaoi fangirls.

A brown-skinned illegal immigrant who bought her name and identity from a ''male'' bum.
----
* AmbiguouslyBrown: She has dark skin and is explicitly an illegal immigrant, but her ethnicity is unknown. She's generally implied to be a Filipina (a Hispanicized real name, her home nation's close proximity to Japan and its poverty-ridden, war-torn history), although she claims her previous school was "Mesopotamia Academy".
* BarefootPoverty: Is portrayed like this with socks ''and'' shoes. Even after the others in the class try and get her into an InstantCosplaySurprise or other normal outfits actually wearing socks and/or shoes, it gives her vertigo because she has never worn them before.
* BoomerangBigot: One episode (where she got obsessed with the BokeAndTsukkomiRoutine) has her making a privileged speech before the Diet to stem the influx of illegal immigrants.
* {{Cloudcuckoolander}}: She even thinks that pedophiles are being ''[[ComicallyMissingThePoint nice toward little children]]''.
%%* CuteLittleFang
* CutenessEqualsForgiveness: She can cause an international incident and get away with it because she's cute.
* FanDisservice: Everything she does.
* GoingCommando: She doesn't wear panties for the same reason she doesn't wear shoes.
* TheIllegal: She's an illegal immigrant to Japan who bought her name and identity from someone else, though it's unknown where she's actually from.
* MamaBear: Evokes this instinct from anyone who sees her, including lawsuit-happy Kaere.
* {{Moe}}: InUniverse, and a {{Parody}} of this type of character. During her introduction, people react to her extreme naiveté with cries of "I have to protect her!", and find her exaggerated poverty to be cute.
* NakedPeopleAreFunny: As the manga went on, her skirt became less magic, and she developed a tendency to flash unsuspecting, poor individuals. Her nudity tends to get played for humour.
* PhraseCatcher: "I want to take care of her!"
* PunnyName: "Taro Sekiutsu" ("Maria" is her given name), a name she bought from a guy willing to sell everything connected to him, can be read as 籍売ったろう -- "seki-uttaro" ("I'll sell my name").

----

-->'''Kafuka:''' Oh, this is the same language my mother used that time. ''([[HilariouslyAbusiveChildhood She goes on to describe a demonic possession and exorcism]])''
* TheChewToy: Fits perfectly.

Also subverted in the FreakyThursday segment of Episode 6 of ''Zoku'', where she's a MotorMouth voiced by Creator/StudioShaft mainstay Creator/ChiwaSaito. [[spoiler:She finally manages to mutter out a "Thank you," in the last chapters of the manga, though Kafuka is the only one to hear her.]]
* DamselOutOfDistress: Gets kidnapped by a pedophile on more than one occasion and always frees herself due to nobody wanting to rescue her.
* FatalAttractor: The only people who fall for the little brat are pedophiles, weirdos, and pathetic losers who can't attract real women. In fact, she gets kidnapped by said pedophiles, weirdos and losers. [[CrossesTheLineTwice A lot.]]
* TheFriendNobodyLikes: Nobody in the class likes her, and it shows when no one comes to her aid whenever she gets kidnapped or abused.
* GirlishPigtails: A short, somewhat spiky pair, held by large yellow ball decs.
* InternetJerk: An odd subversion. She's a seemingly plain old ShrinkingViolet unable to communicate verbally. However, with the power of texting she can (and does) unleash torrents of verbal abuse on the undeserving people around her. However, she does this while only standing a few feet away from them and personally giving them her e-mail address, thus making anonymity irrelevant.
* LittleMissSnarker: Only via text message, though.
%%* LonelyRichKid
* OlderThanSheLooks: She's the same age as the other girls in the class, but she looks like a preteen.
* PunnyName: Her given name is a loan word for "e-mail" ("メール"), and her surname means "soundless". In addition, her email address "hazukashigariyasan" means 恥ずかしがり屋さん -- "full of shyness".
* SituationalSociability: Hardly ever speaks aloud, but put a cell phone in her hand and she will text message people into oblivion.
* TokenMiniMoe: The youngest-looking girl in the class. Deconstructed since her childish looks only manage to get her kidnapped by pedophiles.

A foreign transfer student recently returning to Japan as a student of Class 2-He with a personality split between Kaere, a lawsuit-happy {{Jerkass}} and the in-series UrExample of the "obnoxious foreigner" stereotype, and Kaede, a ShrinkingViolet parody of the YamatoNadeshiko.
----
* AttentionWhore: It's pretty clear that she seeks attention by flaunting herself and then loudly threatening to sue onlookers.
* ButNotTooForeign: She's half-Caucasian (of indeterminate nationality).
* CatholicSchoolGirlsRule: Wears a more westernized school uniform with a plaid skirt, jacket, and long socks.
* CharacterCatchphrase:
-->"I'll sue!"
** Also, this little exchange between her and Nozomu.
--->'''Kaere:''' The (''custom in question'') in this country [i.e., Japan] is/are weird! In the country where I came from we (''perform an extremely bizarre custom'').\\
'''Nozomu:''' I gotta ask... [[WhereTheHellIsSpringfield which country did you come from, anyway]]?
* CustomUniform: She wears a blazer uniform with a plaid skirt instead of a SailorFuku like the other female students.
* DemotedToExtra: For hundreds of chapters at a time, she'll get no dialogue. After Chapter 170, when Itoshiki became less present, Kafuka became more constantly present, and the art gradually began to shift to its old style: she still appears once every 30 or so chapters. After a certain chapter early in the manga's run, she didn't even appear in the background to moon unlucky pedestrians. And this is just Kaere--references to Kaede turn up only a scant handful of times out of those few appearances.
%%* EveryoneLovesBlondes
* {{Fauxreigner}}: A map of Britain appears when Nozomu is discussing her return, but she comes off like a {{Jerkass}} [[{{Eagleland}} American]]... until she starts bringing up animal sacrifices and other pleasantries. She probably just represents the outside world that is blonde and not Japan. [[spoiler:Eventually, it's revealed that the "country" she returned from is the island that Nozomu and the others move to at the end of the manga.]]
* FrivolousLawsuit: As Kaere. The manga volumes even include transcripts of lawsuit documents filed against anyone who offends her throughout the span of said volume.
* HollywoodToneDeaf: Her RunningGag. Ironically, [[Creator/YuuKobayashi her voice actress]] is a singer with a good vocal range.
%%* {{Jerkass}}: As Kaere.
* MagicSkirt: Averted, in comparison to most of her classmates. In fact, they even have a tendency to [[PantyShot fly upwards at the slightest provocation]].
* MsFanservice: Designated, even.
* NonUniformUniform: Except during the finale, probably due to a split personality being active at the time.
* PhenotypeStereotype: She's half-Japanese, half-Caucasian (of indeterminate nationality), and all crazy.
* PunnyName: "Kaere" ("帰れ") is an imperative form of 帰る -- "kaeru" ("go away") -- which is also her SplitPersonality TriggerPhrase; she is [[NamedAfterSomebodyFamous also named after idol Kaela Kimura]].
* ReluctantFanserviceGirl: Keade, who the universe seems to have it in for.
* ShamelessFanserviceGirl: Keare, who flashes everyone, deliberately goes without a bra, and generally makes everyone miserable.
* SplitPersonality: Kaere, the [[{{Jerkass}} insufferable]], and Kaede, the [[ShrinkingViolet shy]], although the former is apparently the more dominant side.
** One chapter has her splitting into even more personalities from different countries. And then they hold a conference.
%%* StatuesqueStunner
* TriggerPhrase: The word "kaeru" ("go away"). When used at Kaere, it turns her into Kaede; used at Kaede, it turns her into Kaere.

A frequently spaced-out girl who wears dresses too big for her, leaves the zipper on the side of her skirt open, and always wears a vacant smile.
----

* {{Cloudcuckoolander}}: She’s ''constantly'' spaced out.
* DissonantSerenity: Sits calmly with a vacant smile on her face amidst the carnage from one of Chiri's rampages.

!!!'''Voiced by:''' Creator/YojiUeda
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/szs_kagero_usui_5767.jpg]]

The ''actual'' Class Representative of Class 2-He. He's one of the few known males in the class, and is so nondescript that his classmates can't even see him, which is why Chiri is treated as the representative.
----
* ButtMonkey: He’s ''so'' nondescript that he’s gone ''invisible''.
* ClassRepresentative: The ''real'' one. He just never gets to call the shots thanks to his invisibility.
* CovertPervert: Hinted to be one -- that, and his invisibility.
** Becomes less covert as time goes on, to the point that he's just proclaimed "Boobs" without context a few times. At one point, Nami remarks how certain things sound a lot dirtier when Usui says them.
* {{Invisibility}}: And he's ''not'' happy about it.
* OutOfFocus: Played with. While he is Nozomu's most recurring male student, he is often ignored whenever he attempts to tell his personal experiences and/or examples related to Nozomu's rant of the moment, meant to be even worse than previous examples presented.
-->''(Random character):'' Did you hear someone?
* PowerPerversionPotential: Despite frequently complaining about his situation, however, Usui has, every now and then, used his invisibility for... less than worthy causes.
* PrematurelyBald: To add insult to injury, he only becomes visible whenever his balding head gets exposed.
-->*Kagero looks at an overembellished avatar Kiri made of him that is still balding*\\
'''Kagero:''' Um, isn't there a part that could use some more embellishment?\\
'''Kiri:''' It's already over-embellished as it is.
* PunnyName: His name is a pun on 影が薄い -- "kage ga usui" ("overshadowed"), while his surname also means "balding".

!!!'''Voiced by:''' Creator/TakahiroMizushima
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/szs_jun_kudou_2090.jpg]]

One of Nozomu's few known male students. He is a master storyteller and can move anyone to tears.
----
* AmbiguouslyGay: Towards his teacher. Very obvious by the end.
* DarkAndTroubledPast: [[spoiler: An illness forced him to get a blood transfusion, causing his incredibly religious family to disown him. He then attempted suicide, but failed.]]
* DissonantSerenity: Unless he's narrating a story, in which case he's a LargeHam, Jun remains calm and smiling in the face of most of the cast's insanity.
* EyesAlwaysShut: A variant, he almost always has one of his eyes closed, making him appear to constantly be giving a sly wink.
* GayOption: [[spoiler: The end implies that Jun was also in love with Itoshiki because he had a blood transfusion from Kafuka, meaning that he's also in the harem.]]
* UsefulNotes/JapaneseChristian: To be precise, he was from a family of Christians of an undisclosed sect (although signs point to Jehovah's Witnesses). In a Halloween manga special, he is seen wearing a cross necklace, claiming that it's for his costume as a priest. The manga ending shows that he is Christian after all and the cross is genuine. Also [[spoiler: the bride Kafuka that Nozomu sees in the church is actually Kudou, hence the green eyes and cross necklace.]]
* LargeHam: When story telling. When not, he's a pretty laid-back guy, especially in comparison to basically everyone else.
* LegallyDead: [[spoiler:He was disowned by his very traditional family because he had a blood transfusion (and presumably tried to commit suicide as the cause) and his name is written as 'deceased', effectively cleaning their hands of him. On a side note, that blood transfusion is hinted to be... let's just say 'from a friend'.]]
** [[spoiler: The fact that he seems to be attracted to his teacher, which is outright confirmed in the ending, makes this a lot more of a TearJerker.]]
* NamedAfterSomebodyFamous: Junkudo-Shoten (ジュンク堂書店), one of the largest bookstores in Kyoto.
* NerdsAreSexy: For a relatively minor character, [[EnsembleDarkhorse he's got his share of fangirls]]. Probably because of all the HoYay he has with Itoshiki.
* NiceGuy: The only person in Itoshiki's class who doesn't or hasn't killed someone, stabbed a stranger in the street, convinced others that they're God, done anything sexually immoral... in fact, he's the only real nice person in Itoshiki's class, the exception being Kafuka. [[AmbiguouslyEvil Sort of.]]
* TheOneGuy: Pretty much the only male student who ever does anything of particular note on a regular basis, other than Usui, who the rest of the cast almost never acknowledge. [[spoiler: Takes on a whole new meaning when you realize he's the only guy in the class also suffering from Kafuka's possessions.]]
* OnlySaneMan: He doesn't seem to have any major quirks or defects like the rest of his classmates do, despite getting it pretty bad.
** Driven home during the "Zetsubou Sensei Drawing Song" segment, where he's pretty much the ''only'' character out of dozens to actually follow the instructions properly and draw something that looks like Nozomu, apart from Abiru, who draws it with hilariously professional quality.
* RedOniBlueOni: The blue oni to fellow story teller Kino's red.
* TheSmartGuy: Compared to his classmates, he's level-headed and intelligent. Not that there's much competition, though, but he still manages to appear more competent than many adults.
* StepfordSmiler: [[spoiler: His past reveals him to have attempted suicide after his family disowned him, and is most likely as depressed as the rest of the cast. Presumably it's a mix of Kafuka's positive energy and him being an all around NiceGuy that it never shows outwardly.]]
* TheStoryteller: His stories, which he makes up on the spot, are apparently so great and heartrending that he's able to make a living off of them.
* TearJerker: InUniverse -- any story he tells can make his listeners cry, including the cynical Nozomu.

!!!'''Voiced by:''' Creator/TakumaTerashima
[[quoteright:180:https://static.tvtropes.org/pmwiki/pub/images/szs_kuniya_kino_1863.jpg]]

One of Nozomu's few known male students and Jin's self-proclaimed rival in storytelling. This is largely an InformedAbility -- as the series went on his main gimmick became his awful, awful fashion sense.
----
* HopelessSuitor: Towards Ai. Considering Ai's personality and the fact that [[spoiler: she is one of the girls that Kafuka can posses means the poor guy never had a chance.]]
* HotBlooded: Though in comparison to most of the rest of the cast this is hardly that weird.
* LargeHam: Unlike Jun he remains one even when not narrating a story.
* LiteralMinded: Revealed to be this during one of the "Zetsubou Sensei Drawing Song" segments, where he follows the song's instructions so literally that his drawing looks nothing like Nozomu.
* LoveTriangle: Marui likes him, but he likes Kaga, while Kaga is either too shy or too oblivious with the affection even though there are several times Kino actively shows it.
* NamedAfterSomebodyFamous: Books Kinokuniya (紀伊國屋書店), Japan's largest bookstore chain, with 56 domestic and 28 overseas branches.
* RedOniBlueOni: The red oni to fellow story teller Jun's blue.
* RummageSaleReject: Outside school, much to Marui's neverending despair. Mostly played for laugh, but there's a FreudianExcuse for it. [[spoiler:Kino's mother was a fallen-from-grace stylist whose fashion sense deteriorated with her depression. Kino keeps wearing her ugly designs, but has actually come to like them.]]
* TheStoryteller: Well, he was supposed to be. Then his awful fashion was brought to the others’ attention.
* ThoseTwoGuys: With Aoyama and Haga.
* UnknownRival: He has a one-sided rivalry with Jun, and it all began when he became ''the'' target of one of Jun's tear-inducing stories.

----
* CovertPervert: She seems to have a thing for sexual sadism.
* ForeheadOfDoom: In the manga, she has a very prominent forehead especially with her front lock swept to the side.
%%* HotTeacher
* IdolSinger: She wanted to be one in her youth, as an EmbarrassingOldPhoto which slipped out of her hands and into Nozomu's reveals. According to Kafuka, Chie was rejected because she was "too pretty".
* MeaningfulName: Her given name means "wisdom", appropriately enough.[[note]]After all, even ignoring the Nietzsche angle, she's still [[OnlySaneEmployee one of the sanest characters in the series]].[[/note]]
* MostCommonSuperpower: In a swimsuit, they're almost the size of her head; Chiri and Meru are in awe and envious.
* MsFanservice: For the first season.
** She even overshadows Kaere at one point when they both appear in swimsuits.
* MsExposition: Shares this status with Mikoto [[spoiler:in the last chapters, explaining the circumstance of Kafuka's HiveMind in class 2-He and Nozomu's reason for persisting in his efforts to teach the misfits. Doubles as SecretKeeper.]]
* NamedAfterSomebodyFamous: Her name can be read together as "niichie", which sounds a lot like Creator/FriedrichNietzsche... [[WhatDoYouMeanItsNotSymbolic for an unknown reason]].
* OOCIsSeriousBusiness: The instigator of a rant about serious people telling jokes, starting when she joked about going on maternity leave. Because she's a relatively serious character who's never told a joke before in the series and did it with a deadpan delivery, everybody takes it completely seriously.
* OutOfFocus: As the school counselor of [[DysfunctionJunction this bunch of basketcases]], she is a fairly important character at the beginning of the series, but has reduced appearances as both the manga and anime progress.
* ThereAreNoTherapists: Ironically enough, since she is a therapist and is surrounded by people who need it, Chie does almost no counselling. The only person she counsels is, from time to time, of all people, Nozomu himself.

* HiddenDepths: He is a fan of RealLife VisualKei band "Nightmare". He also may or may not have been a mercenary and/or a {{Yakuza}} at some point.
* RetiredBadass: He was very much badass in his youth, though now that he's older, he gets pushed around and made into an ExtremeDoormat by others because of his physical frailty. He ends up bordering a Deconstruction of the retired Yakuza man, wishing that he had the strength and courage he had while he was a young man.
** This is deliberately subverted in one of the [=OVA=], in which Jinroku proves he's still got it when three delinquents try entering the school at night. We don't get to see things exactly but we do know they get [[CurbstompBattle curbstomped]], and Jinroku's opening move is a ''FlashStep''.

Chiri's older (and extremely messy) sister.
----
* HeroicSacrifice: She sacrificed her sense of hygiene in order to keep Chiri's pathological obsession with cleanliness in check.
* MoralityChain: Volunterily enforced this trope in order to ensure the safety of her and Chiri's pet goldfish (and possibly all of civilization).
* MoralityPet: Had anyone but Chiri's sister attempted to stall her by creating mess after mess, they would've most likely been dealt with in the most inhumane way possible. But despite Chiri's frustrations concerning her sister's uncleanliness, Tane is still alive and is, to all appearances, unharmed.
** That being said, there are hints that her sister does very harmful things to her, albeit unintentionally.
* ThePigPen: She manages to either create a huge mess of clutter all around her wherever she goes, or attract garbage, literal (e.g. trash) or metaphorical (e.g. drug addicts, hippies, and others at the dregs of society).
* PunnyName: Her name can be read as きったねー -- "kittane" ("dirty").
* SheCleansUpNicely: On the other hand, if she wanted to and had the time, she can groom herself up as perfectly as her sister, such as that time when she dated [[ChickMagnet Nozomu]]. So far she's the only girl whose affection to Nozomu was reciprocated, upon the latter learning of her predicament.
%%* SiblingYinYang: With Chiri.
%%* TrashOfTheTitans
* UncleanlinessIsNextToUngodliness: Inverted. She's the good sister, while neat and clean Chiri is the evil one (sort of).
* WhenItAllBegan: When they were children, Chiri wanted to clean their pet goldfish by pouring ''shampoo'' onto the aquarium. Tane jumped into a pool of mud to distract Chiri and spare the goldfish (and perhaps the rest of humanity) from her murderous obsession with cleanliness.
