List of Sayonara, Zetsubou-Sensei episodes

This article lists the episodes from the anime series Sayonara, Zetsubou-Sensei animated by Shaft and directed by Akiyuki Shinbo. It premiered in Japan on July 7, 2007 on TV Kanagawa and contained twelve episodes. There was also a preface and a "girls collection" bonus OVA.

A Zetsubou Girls Collection DVD was released on January 1, 2008. The DVD consists of seven parts, each featuring one of main heroines with several additions to the original TV broadcast version. A 20-minute summary (preface) was aired on BS11 Digital on January 4, 2008. The second season, Zoku, began airing on January 5, 2008. A set of three Goku OVAs were released, starting with the first volume on October 17, 2008 and the third in early 2009. The Zan season began in mid-2009 and concluded after 13 episodes and two bonus OVAs, the last of which came out in 2010. A special was released in January 2012. Though not part of any season, it still uses the same opening and ending themes as Zan. Each episode title is a literary reference. Each episode ends with a still image drawn by one of manga artists associated with Kōji Kumeta.

01	"Sayonara, Zetsubou-sensei" Transliteration: "Sayonara Zetsubō sensei" (Japanese: さよなら絶望先生)	Yukihiro Miyamoto	Kenichi Kanemaki	Michio Fukuda	July 7, 2007 (2007-07-07)
On the first day of school, Kafuka Fuura finds a man who has hanged himself amidst blossoming cherry trees. She paradoxically pulls him down while strangling him further. Having survived, the downcast man is bewildered by Kafuka's relentlessly optimistic nature, where she denies his suicidal intent wholeheartedly, and bestows him with a nonsensical nickname. Later, at school, the man introduces himself as Kafuka's teacher, Nozomu Itoshiki, and she reveals the portentous writing of his name as "despair" (zetsubou) to the class. Demonstrating his hopeless worldview, Zetsubou-sensei subverts the class's career goals questionnaire as a ranking of least hopeful career goals instead.
02	"When He Came Out of the Long Tunnel, All Was White" Transliteration: "Tonneru o nukeru to shirokatta" (Japanese: トンネルを抜けると白かった)	Yoshihiro Mori	Katsuhiko Takayama	Yoshihiro Mori	July 14, 2007 (2007-07-14)
Charged with visiting Kiri Komori, a problem student who never attends school, Zetsubou-sensei discovers that she is an extreme hikikomori holed up at home. He unwittingly charms her into holing up in the school instead. Then, charged with counseling Matoi Tsunetsuki, a problem student who obsessively stalks each of her boyfriends, Zetsubou-sensei unwittingly charms her into becoming his own stalker instead. He also accidentally shares an infirmary cot with Chiri Kitsu, who, pursuing exactitude in all things, begins demanding marriage.
03	"Jump Across the Country to Me" Transliteration: "Sono Kuni o Tobikoshite Koi" (Japanese: その国を飛び越して来い)	Tomoyuki Itamura	Kenichi Kanemaki	Kazuya Shiotsuki Naoyuki Tatsuwa	July 21, 2007 (2007-07-21)
Kaere Kimura transfers into the class from overseas. Belligerent and at odds with Japanese culture, Kaere alternates personalities with "Kaede", an alter ego who is obedient to Japanese tradition. As expected from Zetsubou-sensei's stereotypical views of foreigners, Kaere presses charges against him for harassment. Then, the student Tarō Sekiutsu is suddenly replaced by a small foreign girl answering to his name. The others discover that the girl, "Maria", is a refugee who illegally immigrated to Japan and purchased Sekiutsu's name. The class warms to Maria's ingénue nature and becomes collectively protective of her.
04	"Be Not Defeated by Elbows, Be Not Defeated by Knees" Transliteration: "Hiji ni mo makezu Hiza ni mo makezu" (Japanese: ヒジニモ負ケズ ヒザニモ負ケズ)	Masayuki Iimura	Katsuhiko Takayama	Jou Tanaka	July 28, 2007 (2007-07-28)
	"The Antenna Is Rising, We Must Try to Live" Transliteration: "Antena Tachinu Iza Ikimeyamo" (Japanese: アンテナ立ちぬ いざ生きめやも)
Abiru Kobushi is a suspected victim of domestic abuse due to ever-present injuries. After much paranoid scrutiny of her father, Zetsubou-sensei discovers that Abiru's injuries all come from horseplay with animals, and especially her fetishizing of their tails. Then, Meru Otonashi's nervous, silent demeanor at first gains Zetsubou-sensei's favor, only for the class to fall victim to her exclusive use of abusive e-mails for communication.
05	"Compare Your Height" Transliteration: "Mi no take kurabe" (Japanese: 身のたけくらべ)	Hideyuki Yoshida	Katsuhiko Takayama	Shuuji Miyazaki Keita Shimizu Hiroki Yamamura	August 4, 2007 (2007-08-04)
	"The Stain and Poison" Transliteration: "Shimi to Doku Dashi" (Japanese: シミと毒出し)
Decrying conspicuous consumption, Zetsubou-sensei measures students' inner worth and cuts their lots in life down to size accordingly. Chiri, in approval, forces downmarket goods and asceticism upon everyone. Then, after a hot spring "detoxes" the students' toxic personalities, Zetsubou-sensei showcases things that lose their appeal when made wholesome.
06	"Leap Before You Glance" Transliteration: "Miau mae ni tobe" (Japanese: 見合う前に跳べ)	Tomoyuki Itamura	Masashi Kubota	Tomonori Kogawa	August 11, 2007 (2007-08-11)
After Zetsubou-sensei declares himself gone missing, his brother, Mikoto, reveals that Nozomu returned to their hometown for marriage by miai. At the estate of the prestigious Itoshiki family, a preposterous miai ritual is held, binding all present to immediate marriage upon making eye contact (also miai). Resisting the designs of his family and students, Zetsubou-sensei demonstrates his lifelong mastery of avoiding eye contact with all things.
07	"Confessions of a Pseudonym" Transliteration: "Kamei no kokuhaku" (Japanese: 仮名の告白)	Yoshihiro Mori	Katsuhiko Takayama	Yoshihiro Mori	August 18, 2007 (2007-08-18)
	"One Morning, Gregor Samsa Awoke to Find Himself Carrying a Portable Shrine" Transliteration: "Aru Asa Guregōru Zamuza ga Me o Samasu to Mikoshi o Katsuideita" (Japanese: ある朝 グレゴール・ザムザが目をさますと神輿を担いでいた)
A miscommunication with Harumi Fujiyoshi, who draws doujinshi fan manga, leads Zetsubou-sensei to attend Comiket to sell literary doujinshi in confusion. After Chiri forces Harumi to draw 4-koma comics, Zetsubou-sensei shows them the secret "fifth panel" that adds a bleak ending to all 4-komas. Then, Zetsubou-sensei and students attend a matsuri where, rather than transporting deities for spiritual worship, the portable shrines are carried by media bosses to hype various unremarkable people for celebrity worship.
08	"I Was Predestined to Be Obscure" Transliteration: "Watashi wa shukumeiteki ni hikagemono de aru" (Japanese: 私は宿命的に日陰者である)	Yukihiro Miyamoto Yuusuke Kamata	Masashi Kubota	Michio Fukuda	August 25, 2007 (2007-08-25)
Zetsubou-sensei discusses the "overshadowing" experienced by various lesser-known adjacents to prominent things, having resigned himself to such a fate. However, when he finally notices Kagerō Usui, a student so "shadowy" that he goes unnoticed by all, Zetsubou-sensei is so horrified as to renounce shadows. Then, a condescending fire officer conducts "criticism drills" by delivering harsh insults to the entire class. To save Kagerō from having his baldness insulted, Kafuka brings the beautiful school counselor Chie Arai to deliver the same insults, transforming the context into erotic humiliation instead.
09	"Evening Primroses Are a Mistake for Mt. Fuji" Transliteration: "Fuji ni tsukimisō wa machigatte iru" (Japanese: 富士に月見草は間違っている)	Hideyuki Yoshida	Kenichi Kanemaki	Yuusuke Kamata	September 1, 2007 (2007-09-01)
Zetsubou-sensei challenges the class to apply spot-the-mistakes puzzles to life, driving everyone to depression by recalling various regrets. Because such puzzles have "correct" answers, however, Kafuka declares all mistakes found this way to be corrected. A boy with a striking resemblance mistakes Zetsubou-sensei for his father, and is suspected of being a "mistake" as in illegitimate child. Then, learning that the boy, Majiru, is his nephew, Zetsubou-sensei demands Majiru, followed by the entire class, to produce proof of their identities. However, when he himself is unable to do the same, the class bands together to gaslight Zetsubou-sensei, causing him to disbelieve his own identity and become an amnesiac drifter.
10	"A Lone Cultured Man Stood Under the Rashomon, Waiting for a Break in the Rain" Transliteration: "Hitori no bunkajin ga Rashōmon no shita de amayadori shite ita" (Japanese: 一人の文化人が羅生門の下で雨やどりしていた)	Yukihiro Miyamoto Tomoyuki Itamura	Masashi Kubota	Michio Fukuda	September 8, 2007 (2007-09-08)
	"I Must Burn Down Namayatsuhashi" Transliteration: "Nama-yatsuhashi o Yakaneba Naranu" (Japanese: 生八ツ橋を焼かねばならぬ)
Believing that the school cultural festival is compulsory under Article 25 of the Constitution of Japan guaranteeing "minimum standards of wholesome and cultured living", Zetsubou-sensei forces the class to lower each possible cultural activity to its "minimum standards". Despite many sorry showings, the class is unable to degrade itself sufficiently and resorts to displaying the "minimum standard" of a classroom lesson. Then, the class takes a "preliminary inspection" of a class trip to Kyoto, which includes the itinerary but no sightseeing. Various types of inexperience and hesitation are also deemed preliminary inspections, followed by preliminary inspections of Zetsubou-sensei's own death.
11	"I Can't Do That, There's Source Material" Transliteration: "Are ikenai yo Gensaku ga aru ja nai ka ne" (Japanese: あれ 不可よ 原作があるじゃないかね)	Yoshihiro Mori	Kenichi Kanemaki	Yoshihiro Mori	September 16, 2007 (2007-09-16)
The students confront a movie director to complain about a film adaptation, but, having followed the source material, he dodges the blame. Zetsubou-sensei guides the class to many pathways representing other things that are followed to escape responsibility, up to and including divine guidance. Then, the students gather at Zetsubou-sensei's house after a surprise decluttering by Chiri. Encouraged by various examples of people withdrawing from society after suffering setbacks, Zetsubou-sensei leads everyone in a group hibernation through winter, but must battle Chiri in a duel of sleep-inducing vs. insomnia-inducing things. In an anime-original cliffhanger ending, after a close call with carbon monoxide poisoning, Zetsubou-sensei contemplates suicide once more, but is hit by a streetcar. The entire class gathers in vigil at a hospital, only for the next episode to ignore the cliffhanger entirely.
12	"What a Nuisance I've Been!" Transliteration: "Nan taru meiwaku de aru koto ka!" (Japanese: なんたる迷惑であることか!)	Masayuki Iimura	Katsuhiko Takayama	Tatsuya Oishi	September 23, 2007 (2007-09-23)
When Ai Kaga compunctiously takes blame for imagined offenses to others, Zetsubou-sensei identifies various other Japanese tendencies to yield or self-reproach. Before long, he yields to the entire world by suicide, only to return to life to take the blame for dying. Then, Mayo Mitama, an outright malicious girl having a face to match, constantly escapes blame due to the fear of judging by appearances. Thus, even after repeatedly catching her red-handed, taking blame for her crimes, and then falling victim to them, Zetsubou-sensei denies her culpability.

01	"Listen, the Baron Is Ranting" Transliteration: "Hora, danshaku no mōgen" (Japanese: ほら, 男爵の妄言)	Yukihiro Miyamoto	Yukihiro Miyamoto Naoyuki Tatsuwa	January 5, 2008 (2008-01-05)
	"This Class Has Many Issues, Thank You for Your Understanding" Transliteration: "Tōkumi wa Mondai no Ōi Kyōshitsu desu kara dōka Soko wa Goshōchi Kudasai" (Japanese: 当組は問題の多い教室ですからどうかそこはご承知ください)
In an adaptation of the joke jacket blurb from the first manga volume, Nozomu Itoshiki, a multi-level marketing salesman, faces various Kafkaesque tribulations: being hunted by a secret society called "Hamasho", being transformed into a half-mole cricket, becoming a castaway, becoming a teacher at an all-girls school and receiving a nonsensical nickname, and being pressured into a marriage of convenience. Then, Nami Hitō, seeking pity by missing school and telling sob stories, is thwarted at every turn when the circumstances of Zetsubou-sensei and his class prove more piteous by far. Accepting a dare to prove that staying away is more piteous than staying at school, Nami is sent fleeing by Kafuka's macabre after-hours antics. Later, Nami is chagrined to have her reactions called normal.
02	"When You Opened Up Your Bangs for the First Time" Transliteration: "Mada akesomeshi maegami no" (Japanese: まだ明け初めし前髪の)	Akira Katou	Noboru Jitsuhara Tomoyuki Itamura	January 12, 2008 (2008-01-12)
	"Decorations at Tiffany's" Transliteration: "Tifanī de sōshoku o" (Japanese: ティファニーで装飾を)
	"Rouse Up, O Young Men of the Old Age!" Transliteration: "Atarashikunai Hito yo, Mezame yo" (Japanese: 新しくない人よ、目覚めよ)
A strange man arrives at school, brazenly "opening" many things in different senses. He discovers that Zetsubou-sensei's heart resists opening, only to be engulfed by a nightmarish reality within. The man finally learns about various things that should not be opened. In the broadcast version of this segment, all voice acting is gibberish, and the intended script is replaced with joke subtitles. The proper voice track released on home video tells the original story from chapter 12 of the manga: the man is pretending to be Commodore Perry, known for "opening" Japan to foreign trade. Then, Zetsubou-sensei and Kafuka argue whether various ostentatious things are overembellished or, in fact, masterful. Zetsubou-sensei ends up afflicted by a curse that can only be warded off by becoming overembellished with sutras by his brother Kei. Then, Zetsubou-sensei and an old friend reunite and appreciate various things said to be "old". The old friend attempts to wed Zetsubou-sensei's sister, Rin, to render his birth name "old". Finally, by writing the character for "old" differently, Kafuka reinterprets many "old" things as things that lasted only "one day". Throughout this segment, the wrong background is drawn, but is not acknowledged by the characters.
03	"You're 17, Don't You Want to Pinch Your New Wrinkles?" Transliteration: "Jūnana-sai ne, jibun no shiwa o tsukande mitaku nai?" (Japanese: 十七歳ね, 自分のシワをつかんで見たくない?)	Yuusuke Kamata	Yuusuke Kamata	January 19, 2008 (2008-01-19)
	"Obligations and Soldiers" Transliteration: "Gimu to heitai" (Japanese: 義務と兵隊)
	"'Don't Drop a Bombshell Like That On Me!' Rebuffed Melos as He Got to His Feet" Transliteration: "'Saratto iu na!' To merosu wa, ikiritatte hanbaku shita" (Japanese: 「さらっと言うな!」とメロスは、いきり立って反駁した)
The class discusses age-denying ways of life, including that of Manami Ōkusa, a student who is also a working housewife with a debt-ridden husband. Kikuko Inoue, the voice of Manami, also appears as herself to deliver her trademark age-denying catchphrase. This story is performed as a radio play heard in the background while Harumi draws a doujinshi, only to discover that she has chosen an unpopular pairing. Then, Zetsubou-sensei interprets the personal trademark looks and signatures of various celebrities as social obligations. The class observes failed personal trademarks that turn into self-imposed obligations, as well as impositions that turn into obligations for others. Then, Zetsubou-sensei nonchalantly holds the class back a year, and explains various other explosive revelations that are made offhandedly. The class contributes first-hand examples, including Rin's surprise enrollment. Everyone joins in on making, and reacting to, mundane revelations explosively.
04	"Roadside Artist" Transliteration: "Robō no eshi" (Japanese: 路傍の絵師)	Yoshihiro Mori	Yoshihiro Mori Yuuichi Nakazawa	January 26, 2008 (2008-01-26)
	"I Have Read Books Full of Shame" Transliteration: "Hazukashii Hon bakari Yondekimashita" (Japanese: 恥ずかしい本ばかり読んできました)
	"Summer of the Usume" Transliteration: "Usume no natsu" (Japanese: 薄めの夏)
The class discusses various trivialities that distract from larger concerns. Suddenly, aliens invade with an army of giant robots. The students excavate a stone mask that transforms Chiri into a giant. The alien commander, distracted by voyeuristic reconnoitering, fails to defend against the larger concern of Chiri's counterattack, while others are distracted from the spectacular story by off-color observations. Then, Zetsubou-sensei, intimidated by Jun Kudō's vast repertoire of read books and skilfully empathetic storytelling, fears that Jun can "read" many other things, including hearts, minds, and the ending of this segment. In defiance, he substitutes a non-sequitur ending that no one could have "read". Then, an idle scene between Majiru and Kiri during the alien invasion is shown in full. Viewer metrics arrive, proving that this inconsequential segment was more engrossing than the main story.
05	"Family Tree of the Arts" Transliteration: "Bunka eizu" (Japanese: 文化系図)	Masayuki Iimura	Masayuki Iimura Tomonori Kogawa	February 2, 2008 (2008-02-02)
	"I Always Called Him 'Leftover'" Transliteration: "Watashi wa Sono Hito o Tsune ni Nokorimono to Yondeita" (Japanese: 私はその人を常に残りものと呼んでいた)
	"Beyond the Pale of Condescension" Transliteration: "On kise no kanata ni" (Japanese: 恩着せの彼方に)
At Zetsubou-sensei's behest, the class sits out of the school athletics festival to participate in a "cultured" version without any athletics. He draws increasingly belabored distinctions between "athletic" things and non-athletic counterparts that are either science or art in nature, and vice versa. Then, Zetsubou-sensei views fukubukuro with deep suspicion that they merely contain undesirable leftover inventory. This yields a discussion of desirable leftovers, and other things that are left over in various senses. Then, Zetsubou-sensei questions the virtue of good deeds done while expecting gratitude. The class demonstrates that such self-serving expectancy extends to even due courtesies and manipulative pricing tactics. Humbled by these examples, Ai begins denying all gratitude from others, and accidentally becomes a tsundere.
06	"I Beg You, Do Not Know" Transliteration: "Kimi shiritamō koto nakare" (Japanese: 君 知りたもうことなかれ)	Akira Katou	Akira Katou	February 9, 2008 (2008-02-09)
	"The Tale of Hoichi the Dreamless" Transliteration: "Yumenashi Houichi no Hanashi" (Japanese: 夢無し芳一の話)
	"Concealed Soldier" Transliteration: "Inpei-sotsu" (Japanese: 隠蔽卒)
Just as most students would rather not know their grades, Zetsubou-sensei lists many other off-putting things that one would rather not know. He departs to the wilds to escape all knowledge, only to be surrounded by prophetic omens of the natural world. Giving up, he seeks out the omniscient knowledge of a neighborhood gossip. Then, in Zetsubou-sensei's dream, the personalities of everyone in class are reversed. The students turn murderous in order to grant him "eternal sleep". Zetsubou-sensei is desperate to wake up in a dream ending, but, in series tradition, only receives non-endings in the form of non-sequitur jokes. Then, taking literally the Japanese for "wisdom tooth", the class goes forth to find various things unknown to one's parents. Because his wisdom teeth are also unknown to his parents, Zetsubou-sensei sends various notices in desperation to avoid having them pulled. Throughout this segment, all voice actors are switched periodically.
07	"The Cat That Was Told a Million Times" Transliteration: "Hyakumankai iwareta neko" (Japanese: 百万回言われた猫)	Yukihiro Miyamoto	Asushi Nishigori Takahiro Yoshimatsu	February 16, 2008 (2008-02-16)
	"Red Riding Hood Sleeps, Be Careful" Transliteration: "Aka zukin-chan, neru. Ki o tsukete" (Japanese: 赤頭巾ちゃん、寝る。気をつけて)
	"Tsugaru Correspondence Learning" Transliteration: "Tsugaru Tsūshin Kyōiku" (Japanese: 津軽通信教育)
The episode opens as a parody of a magical girl anime, complete with opening theme song. Then, after once again having his name read as zetsubou, Zetsubou-sensei sympathizes with various people who, due to their circumstances, have heard the same overly apt puns, one-liners, and assumptions numerous times. Then, on "Zetsubou Channel", brief pastiches of various TV shows are shown, including the continuation and conclusion of the earlier magical girl show. Then, noticing Japan's indulgence of students studying for university entrance exams, Zetsubou-sensei schemes to become a lifelong exam-taker through certification exams. After achieving every possible certification in life, he once again resorts to suicide, but is stymied by a gauntlet of challenging exams to qualify for dying. Throughout this segment, artstyles are switched periodically, including shadow theatre, collage, claymation, psychedelia, and flip book animation.
08	"Spineapple Pudding" Transliteration: "Supainatsu purin" (Japanese: スパイナツプリン)	Masayuki Iimura	Masayuki Iimura	February 23, 2008 (2008-02-23)
	"When the Exposures Bare Fruit" Transliteration: "Bakuro no mi no juku suru toki" (Japanese: 暴露の実の熟する時)
	"The Curious Casebook of Inspector Hanbun" Transliteration: "Hanbun torimono-chō" (Japanese: 半分捕物帳)
Zetsubou-sensei laments various innocent situations where one is suspected of spying. After numerous such accusations, he sincerely turns traitor to Japan, but his new masters suspect him of being a double agent. Kafuka mounts a counterintelligence campaign by spreading inane urban legends. Then, with the arrival of May, Zetsubou-sensei points to various people who reveal their true selves after some time, especially with the passage from April to May. Then, on Autumnal Equinox Day, which is half daytime and half nighttime, Zetsubou-sensei illustrates idiomatic "half" things that are not literally halved. Chiri forcibly alters various "half" things to be scrupulously literal. This segment is animated as if printed on paper, with minimal motion.
09	"As They Say, It's Better to Be a Couple than a Single" Transliteration: "Pin yori Konbi no hō ga ee iu koto dessharo" (Japanese: 一人より女夫の方がええいうことでっしゃろ)	Hiroaki Tomita Ayumu Kotake	Hiroaki Tomita Hiroyuki Imaishi	March 1, 2008 (2008-03-01)
	"The Secret Passage to the Interior" Transliteration: "Oku no nukemichi" (Japanese: 奥の抜け道)
In a series of Ultraman parody segments, the cast plays out crude fights as tokusatsu monsters. After watching manzai comedy, Maria identifies people letting down their guard in various ways as having become boke, and physically assaults them according to manzai convention. After discovering that not all boke have their guards down, Maria is indoctrinated by nationalists and attacks Japan's foreign policy as boke in the National Diet. Then, deeming in-school inspections insufficiently surprising, Zetsubou-sensei institutes covert surprise inspections—in which everyone is caught on embarrassing photos. Chiri is appalled by the carelessness on display throughout society, but Kafuka reminds her of the comic appeal of careless blunders. Chiri assiduously commits blunders, leading to life-and-death consequences—mostly for Zetsubou-sensei.
10	"Deteriorated Blossoms, Flowing Water" Transliteration: "Rekka ryūsui" (Japanese: 劣化流水)	Yuusuke Kamata	Yuusuke Kamata Tomonori Kogawa Tomoyuki Itamura	March 8, 2008 (2008-03-08)
	"A Fool's Work" Transliteration: "Chijin no ari" (Japanese: 痴人のアリ)
	"The First-time Customer Condition" Transliteration: "Ikken no Jō-ken" (Japanese: 一見の條件)
Zetsubou-sensei remarks on the newfound appeal of things that are "detuned", where their performance is curbed or imperfections are added. Many merely underwhelming things are used as ironic examples as well. Then, Zetsubou-sensei warns that, just as fashion victims fall for ill-considered styles at the whims of fashionistas, anyone can be led astray to obviously bad ideas at the whims of others. He too is led at the whims of others into ill-advised romances with many of the students. Then, realizing that the show—like various exclusive establishments and subcultures—is no longer accessible to newcomers, the cast extends hospitality to first-time viewers by obligingly explaining every character and joke. Zetsubou-sensei soon chases out the newcomers in exasperation, but learns that regular viewers, who incessantly call out references and anticipate jokes, are similarly insufferable.
11	"Twelve Dark Zetsubou Girls" Transliteration: "Kuroi jūni-nin no zetsubō shōjo" (Japanese: 黒い十二人の絶望少女)	Yukihiro Miyamoto Shouji Saeki	Shouji Saeki	March 15, 2008 (2008-03-15)
	"May This Moon on This Night of This Month Be Clouded by My Tears" Transliteration: "Kongetsu Kon'ya no Kono Tsuki ga Boku no Namida de Kumorimasu yō ni" (Japanese: 今月今夜のこの月が僕の涙で曇りますように)
In a parody of a Kosuke Kindaichi mystery, Detective Nozomu Itoshiki is called to investigate serial murders targeting the twelve young mistresses of the late Sakebu Itoshiki (no relation). The detective accuses Kagerō, Sakebu's previously-unnoticed son, of committing the ritual murders based on his father's beloved anime series, not realizing that this was a red herring: luring the detective to the estate's warehouse, the surviving girls reveal that they are killing other in jealousy out of their shared, unrequited love for Sakebu. Brandishing knives, the girls demand that Nozomu—who is a dead ringer—take Sakebu's place, but he flees while accidentally burning down the warehouse. True to his reputation, "Detective Zetsubou" once again solves the case, only for all involved parties to end up dead. Then, because Zetsubou-sensei predicts that Tanabata wishes will never come true in a lifetime, Kafuka reasons that they will, therefore, be granted in next lifetimes, spontaneously inspiring a cult to form.

	"Pororoca Riding the Waves" Transliteration: "Nami ni notte kuru pororokka" (Japanese: 波に乗ってくるポロロッカ)
For the sake of acclimatization, Zetsubou-sensei adds school holidays to the month before summer vacation, winning the class's support. He teaches how to likewise downplay various rude awakenings as "soft landings" instead of "hard landings", aided by a flight simulator in which one "lands" using polite fictions. To the class's dismay, Zetsubou-sensei's holiday plan is approved hand-in-hand with adding school days over summer vacation. Then, Zetsubou-sensei inadvertently plays parts (inevitably bit parts) in various other people's momentous occasions. Then, observing the tidal bore phenomenon, Zetsubou-sensei showcases other cart-before-the-horse phenomena, especially fans who discover their interests not firsthand, but secondhand through pop culture. Kafuka praises such circuitous pursuits as "manly", rallying a chorus of men who collectively confess the dubious gateways for their various hobbies. Likewise, Zetsubou-sensei's old friend becomes belatedly named "Ikkyu-san" after his debut.

	"(Assuming That We Are) Brother and Sister" Transliteration: "A ni imou to, to iu zentei de." (Japanese: あにいもうと、という前提で。)
Setsubun bean-throwing prompts Zetsubou-sensei's concern that society not only indiscriminately drives out unwanted oni, but also relegates various people who fell from favor to "strays". Many such "stray" public figures are brought into Zetsubou-sensei's care, causing the school to fire him. Reduced to a "stray teacher" in the far north, Zetsubou-sensei is touchingly reunited with the class after devolving to a stray dog. Then, Meru's father holds an audition to recruit a live-dub replacement for Meru's repressed voice, enlisting various wildly inappropriate candidates. Meanwhile, Jun performs rakugo. Then, Zetsubou-sensei identifies various hasty actions based on assumptions, whether in colloquial, professional, or romantic settings. Arriving in Akihabara, he encounters the cynical assumptions made in marketing and pandering to otakus. Finally, a battle manga character acts out a stereotypical rivalry with Zetsubou-sensei, mistakenly assuming that he will join the cast.

	"A Shield of the Original" Transliteration: "Genkei no tate" (Japanese: 原型の盾)
After receiving many Valentine's chocolates from the class, Zetsubou-sensei frets about falling victim to honey trapping. Kafuka reveals that seductive female spies have been neutralized in Japan by entrusting state secrets to otaku who shun real women for animated characters. What's more, these "elites" are also immune to anime merchandise honeypots, due to the inferior quality of foreign bootlegs. Then, watching a boring talent competition, Zetsubou-sensei contemplates various competitions with vicious behind-the-scenes intrigues that go unseen. He soon discovers that the students' vicious behind-the-scenes battles for his affection likewise go unseen. Then, wearing an old-fashioned costume to an all-cosplay Halloween party, Zetsubou-sensei bemoans Halloween tradition and other things that bear no resemblance to their former selves. Finally, because artist Kumeta's artstyle no longer resembles its former self, Zetsubou-sensei reverts to Kumeta's early artstyle.

Performing his duty to visit students' homes, Zetsubou-sensei lingers on the way to Chiri's house but leaves immediately upon arriving. The animation changes to Kumeta's early artstyle again, as Zetsubou-sensei accuses Japanese culture of lingering on process while neglecting outcome in various ways, and lampoons the popularity of immature characters and coming-of-age stories. Kafuka reveals that, after the spurned Chiri attacked him, Zetsubou-sensei has been lingering in a hallucination in the "process" of falling to his death. Then, buying into a popular earthquake forecast hoax, the cast, certain that their appearance in this very story will not make print, becomes demotivated. Zetsubou-sensei compares their token efforts to various other futile efforts that people knowingly make. Throwing caution to the wind, the cast indulges in blatantly unprintable mischief (all replaced with sanitized placeholders). Then, nitpicking the non-descriptive titles of famous books, Zetsubou-sensei encourages both Kuniya Kino and Jun to retitle them in literal fashions. To make the title Sayonara, Zetsubou-sensei literal, Chiri sends off Zetsubou-sensei to certain death with a title drop. This segment is animated in a gothic manga artstyle.
03	"Dialogue in the Darkness" Transliteration: "Anchū Mondō" (Japanese: 暗中問答)	Yukihiro Miyamoto Masayuki Iimura	Naoyuki Tatsuwa	February 17, 2009 (2009-02-17)
	"The Loser Book" Transliteration: "Maketa no sōshi" (Japanese: 負けたの草子)
	"Tall Tales from Japan" Transliteration: "Ichi-pon mukashibanashi" (Japanese: 一本昔ばなし)
The class depicts the difficulty of writing new jokes in a long-running manga by telling joke ideas in the game of "one hundred scary stories". Frighteningly (for the writer), every joke offered is rehashed, unfunny, or inopportune somehow. After Kafuka suggests this very premise as the forbidden one hundredth joke, everyone meets a terrible fate: coming up with more ideas the next day. Then, the class stumbles onto a battlefield and observes various arguments and contests so self-debasing that both sides come off as losers. Kafuka then explains other battles where both sides "win"—by collusion. Then, in an anime-original flashback segment, young Nozomu is recruited by a shady high school club that discovered his hidden potential for negativity.

After Zetsubou-sensei expounds on the excesses and unintended consequences of superstitions, other teachers—fearing his inauspicious name—imprison him to protect university entrance exam takers. Zetsubou-sensei's students, combining their talents, stage a prison breakout. The jailers are placated when Kafuka invents a new superstition turning Zetsubou-sensei into an exam-taking good luck charm. Then, on a pleasant spring day, the class finds many unpleasant tidings of spring—in society. Chiri demands that these "tidings" be replied in kind, forcing the others to one-up the pantomimes of kooks and exhibitionists who appear in spring. Then, as Nami departs on a "self-discovery" tour, Zetsubou-sensei warns that tourists invariably reveal their worst selves. In allowing Rin to lure him onto the tour, he likewise reveals his own incorrigible voyeurism. The story continues in the next episode.

	"Wuthering Blights Part 2" Transliteration: "Sarashi ga oka pāto 2" (Japanese: 晒しが丘 パート2)
Admiring talented people who are endowed with more than one gift, Zetsubou-sensei imagines their possible alternate lives. Because society has already pigeonholed these people by singular talents, the class tours a parallel world where many alternate callings have flourished. Then, Zetsubou-sensei explains various things that belatedly take effect, such as delayed-release pills or slow-dawning realizations. The segment ends with a belated punchline to a years-old joke from Katteni Kaizō. Then, continuing from the previous episode, Kafuka charismatically leads the tourists on a cultlike mass confession of personal failings. Horrified, Zetsubou-sensei swaps places with a kagemusha decoy to hide his own failings.
03	"The Tragedy of ✕" Transliteration: "Peke no Higeki" (Japanese: ×の悲劇)	Yukihiro Miyamoto Naoyuki Tatsuwa	Naoyuki Tatsuwa	July 18, 2009 (2009-07-18)

	"Doctor Kahogo" Transliteration: "Dokutoru kahogo" (Japanese: ドクトル・カホゴ)
Kafuka discovers literal power switches for various people who are "switched on" by mention of their hobbyhorses. Zetsubou-sensei's own switch turns out to be a self-destruct. Then, Zetsubou-sensei commiserates with the class on indecisions between two choices that lead to choosing neither. They cite many baffling, regrettable "third choices" that are settled on, and other third options such as equivocating. Then, thoroughly protected from danger by his decoy, Zetsubou-sensei is brought to a gathering of people who overprotect their own persons or possessions. The story continues in the next episode.
04	"How I Became an Honest Man" Transliteration: "Yo wa Ika ni Shite Maningen to Narishi ka" (Japanese: 余は如何にして真人間となりし乎)	Yukihiro Miyamoto Yasuo Iwamoto	Naoyuki Tatsuwa Tomoyuki Itamura	July 25, 2009 (2009-07-25)

	"Doctor Kahogo Part 2" Transliteration: "Dokutoru kahogo pāto 2" (Japanese: ドクトル・カホゴ パート2)
The class discusses things that are done at the wrong place or time. Zetsubou-sensei grouses that even consciously minding place and time can backfire. However, because improper place and time makes for popular entertainment, everyone time travels to the Sengoku period, which was the wrong place and time for nearly everything. Then, holidaying on Marine Day, the class discusses special occasions that can't be celebrated—including, for those in the rat race, holidays in general. Accordingly, the class learns various ways to holiday without enjoying oneself. Then, continuing from the previous episode, Zetsubou-sensei is beset by the overprotectiveness of copyright enforcement, public safety, and obtrusive promotion. Renouncing his decoy's protection, he realizes that the decoy spent the day on a date with Abiru.
05	"Overmassaging" Transliteration: "Katatataki" (Japanese: 過多たたき)	Yukihiro Miyamoto Toshikatsu Tokoro	Naoyuki Tatsuwa	August 1, 2009 (2009-08-01)

	"The Releaser in the Rye" Transliteration: "Raimugi hata de minogashite" (Japanese: ライ麦畑で見逃して)
The class compares examples of puffery and superlatives, which inspire incredulity rather than trust. They play a game of old maid where players try to discard not suited cards, but superlative epithets. Zetsubou-sensei loses, and becomes saddled with a hyperbolic nickname. Then, just as the year gained a leap second, Zetsubou-sensei suspects that society has likewise discreetly gained "leap people". The class finds various examples of people who number more than reckoned, such as uninvited guests, astroturfed turnouts, and expanding band lineups. Then, Zetsubou-sensei uses the Hōjō-e festival—when caught animals are released, and forgiveness is practiced—as an excuse to be released from Abiru's possession, begging that his decoy's tryst be likewise forgiven. He follows Kafuka's advice to practice blissful ignorance, by learning to forgive all discrepancies and red flags. The story continues in the next episode.
06	"The Measles of Madison County" Transliteration: "Madison-gun no Hashika" (Japanese: マディソン郡のはしか)	Yukihiro Miyamoto Kazuhide Kondou	Naoyuki Tatsuwa	August 8, 2009 (2009-08-08)

	"The Releaser in the Rye Part 2" Transliteration: "Raimugi hata de minogashite pāto 2" (Japanese: ライ麦畑で見逃して パート2)
News of a measles outbreak leads the class to consider other ills that are more safely befallen in childhood than adulthood, such as unhealthy fixations and iniquitous urges. Then, Zetsubou-sensei is troubled by a hardline political poster at Kanako Oura's home, but then sees that she has simply openhandedly allowed posters from an assortment of parties. Observing that problems appear less egregious in greater assortments, he reasons that making a problem sufficiently multifarious will smooth it over. However, he learns that starting multifarious love affairs does not smooth over his students' murderous jealousy. Then, continuing from the previous episode, Chiri combats ignorance by affixing maker's marks to all things and people, only for Kafuka to insinuate esoteric gods as the makers of all mankind.
07	"Do Androids Dream of Mechanical Brides?" Transliteration: "Andoroido wa Kikai no Hanayome no Yume o Miru ka" (Japanese: アンドロイドは機械の花嫁の夢を見るか)	Naoyuki Tatsuwa Masanori Takahashi	Naoyuki Tatsuwa Tomoyuki Itamura	August 15, 2009 (2009-08-15)

	"Ahh, a surprise, I murmured in a daze" Transliteration: "Aa Sapuraizu da yo, to Watashi wa Utsuro ni Tsubuyaku no de Atta" (Japanese: ああサプライズだよ、と私はうつろに呟くのであった)
Miko Nedu and Shoko Maruuchi fleece Zetsubou-sensei by running a razor and blades racket. Kiri chides him as well as Majiru—who is collecting a build-a-figure toy—for irresponsible spending, but she soon dips into household funds to likewise build a life-size Zetsubou-sensei automaton. Majiru accidentally breaks the automaton, and gaslights his real uncle into taking its place as Kiri's obedient plaything. Then, on a warm winter day, the class finds the ailing "winter shogun", the personification of cold winters in Japan. The shogun quits to seek a new job, but cannot personify anything so compellingly as befits a shogun. Everyone is soon reminded that being dubbed "shogun" is so common as to be unflattering today. Then, to surprise Zetsubou-sensei, the class throws him a birthday party on the wrong day. Chiri's havoc-wreaking entrance fails to surprise, illustrating Zetsubou-sensei's point that life's unwelcome surprises have raised the bar for unexpected things. The story continues in the next episode.

	"The End and the Beginning of Enoden" Transliteration: "Saigo no, soshite hajimari no enoden" (Japanese: 最後の、そして始まりのエノデン)
Continuing from the previous episode, the class is shown how only anticlimax can surprise those expecting to be surprised. Then, hoping for future clemency, Zetsubou-sensei undertakes confession "training" despite having no crime to confess yet. The class also practices group confessions and reacting to confessions. Catastrophically, with widespread confessions, all popular drama resolves prematurely and all sectors of society are mired in scandal. Then, aboard a "mystery train", Zetsubou-sensei observes that just as the train's "mystery" destination is predecided, the passengers seek opinions on various matters that they have already decided. He finds many other such "trains", such as leading opinion polls, presumption of guilt, and discriminatory screening. Finally, he boards a train bound for the "station" of putting off important decisions—the most popular destination of all. This segment is animated using bricolage artwork.
09	"The Emergency That Became a Nun" Transliteration: "Ama ni Natta Kyūba" (Japanese: 尼になった急場)	Yukihiro Miyamoto Masayuki Iimura	Naoyuki Tatsuwa Masayuki Iimura	August 29, 2009 (2009-08-29)

	"Jeremy Thatcher, Long-Drive Hatcher" Transliteration: "Jeremī to dorakon no tamago" (Japanese: ジェレミーとドラコンの卵)
As Zetsubou-sensei surmises, the class is skilled at resorting to various emergency makeshifts, such as makeshift birthday presents, fake makeup, and payday loans. When the students accidentally kill Zetsubou-sensei, Chiri deploys other makeshifts such as hiding bodies and eliminating witnesses. Then, the classroom transforms into a quiz show, and Zetsubou-sensei poses various situations where correct answers should not be given, for reasons such as sycophancy, diplomacy, and overscrupulousness. The contestants' discretion is further challenged with questions asked by depressed people. Kafuka sends Zetsubou-sensei back in time to the pre-Enlightenment, where he is executed for speaking heretical truths. Then, after practicing at a driving range, the class is ushered to other "tees" which test the "range" to which one can venture out of one's comfort zone—while committing various faux pas or deprived of various crutches. The story continues in the next episode.
10	"The Egg of the Crack" Transliteration: "Kurakku na Tamago" (Japanese: クラックな卵)	Yukihiro Miyamoto Kazuhide Kondou	Naoyuki Tatsuwa Kazuhide Kondou	September 5, 2009 (2009-09-05)

	"Jeremy Thatcher, Long-Drive Hatcher Part 2" Transliteration: "Jeremī to dorakon no tamago pāto 2" (Japanese: ジェレミーとドラコンの卵 パート2)
Zetsubou-sensei applies the chicken or the egg dilemma to everything, imagining absurd examples of bootstrapped causality where effects precede causes. Finally, he contemplates whether hope begat hopelessness, or vice versa. Then, Zetsubou-sensei becomes paranoid that everyday laggards and nuisances, who hold up daily life to the point of sabotage, could actually be undercover saboteurs. Chiri misunderstands the word "spy" in Japanese, causing her to give away trade secrets to industrial spies, and then teach spycraft to children in place of arts and crafts. Then, continuing from the previous episode, Kafuka tests how near one can approach various things before getting too close for comfort.
11	"Glasses Girl's House" Transliteration: "Meganekko no Ie" (Japanese: 眼鏡子の家)	Naoyuki Tatsuwa Yuu Nobuta	Naoyuki Tatsuwa Akira Takamura	September 12, 2009 (2009-09-12)

	"The Garment Seen by the Scholar Ageashitori" Transliteration: "Gakusha ageashitori no mita kimono" (Japanese: 学者アゲアシトリの見た着物)
The class takes up a collection to buy new glasses for Zetsubou-sensei, but discover a shop selling "tinted glasses" that bestow various kneejerk prejudicial worldviews. The proprietor observes that everyone is wearing such glasses, even without patronizing his shop. Then, everyone in class is under lockdown at home for reasons unspecified. Seeking diversions, Rin impetuously purchases neighboring houses to move freely through town. The story continues in the next episode. Then, the students perform provocative high kicks while cheerleading. Zetsubou-sensei notes that public attention-seekers also commit provocative gaffes for notoriety or patronage. Understanding that they must not take the bait, the class practices steering clear of provocative "high kicks"—and countering with their own.
12	"After the Third Time" Transliteration: "Sanji no Ato" (Japanese: 三次のあと)	Yukihiro Miyamoto Naoyuki Tatsuwa Yuusuke Kamata	Naoyuki Tatsuwa Yuusuke Kamata	September 19, 2009 (2009-09-19)

	"An Encouragement of Lockdown Part 2" Transliteration: "Heimon no susume pāto 2" (Japanese: 閉門ノススメ パート2)
A discussion of Schrödinger's cat inspires the class to hide things in boxes, to foster hope in the unobserved "infinite" possibilities of even foregone conclusions. Soon, everyone in class is wearing cardboard box outfits. Then, the class finds the Taepodong-2 missile landed in the schoolyard. Fearing that they will be forcibly disappeared for national security, everyone concocts various ruses to disguise the towering missile. They discover that the missile was a fake carrying brainwashing propaganda, only for the real missile to touch down. Then, continuing from the previous episode, Nami, desperately bored at home, takes over tunneling through properties as Rin acquires them—to a ramen shop, to a karaoke box, and finally to school, where everyone resumes classes despite still being under lockdown. Then, the softcore porn parody starring Kaere from episode 4 is continued.
13	"Revenge on Misspelled Temple" Transliteration: "Gojiingahara no Katakiuchi" (Japanese: 誤字院原の敵討)	Yukihiro Miyamoto Kazuhide Kondou	Naoyuki Tatsuwa Masayuki Iimura Kazuhide Kondou	September 26, 2009 (2009-09-26)
	"We Are Linus" Transliteration: "Ware-ra rainasu" (Japanese: われらライナス)
	"The Grand Prize of Optimism" Transliteration: "Rakuten taishō" (Japanese: 楽天大賞)
The home video release of this episode opens with the cast reflecting on the author's self-criticism of the "Kiyohiko Night" story which concludes this episode. After meticulously straightening a painting on exhibit, Chiri fails to notice that it is upside-down. Appropriately, the exhibit collects major mistakes which were let past while catching minor ones. Then, when Kiri loses her security blanket, it is found by Prime Minister Tarō Asō and mass-produced as social security. With Kiri overwhelmed by becoming an economic stimulant, the class considers other "security objects", such as schadenfreude, civil service employment, and Zetsubou-sensei himself. Then, Maria mishears the word of the year award and accidentally summons personifications of past words of the year—all of whom have become obsolete. Finally, on Christmas Eve, Maria mishears "Silent Night" in Japanese as "Kiyohiko Night", and accidentally summons a man called Kiyohiko. Everyone decides to celebrate his fondest desires.

During May Day labor rights demonstrations, Zetsubou-sensei observes that the "demo" in "demonstration" (literally "but" in Japanese) dooms Japanese activism to halfhearted protests that are undermined by caveats, reservations, and second thoughts. His own contrarian nature is exploited similarly to undermine a boycott of the 2008 Olympic Games. Then, as Nami pretends to appreciate Tomihiko Morimi's The Night Is Short, Walk On Girl, Zetsubou-sensei calls out affectation of intellectualism by lowbrow people. Being lowbrow one and all, the class decides to affect highbrow comedy by faking in-jokes with esoteric references, only to confuse themselves. Then, Chiri's slovenly older sister, Tane, returns home. Chiri becomes constantly preoccupied with tidying the heaps of trash that Tane spontaneously generates. Zetsubou-sensei learns that Tane became a slob in self-sacrifice, to divert Chiri's compulsive cleaning away from harmful ends. He and Tane become mutually enamored.

	"The World with Words" Transliteration: "Kotoba no aru sekai" (Japanese: 言葉のある世界)
After a classroom AED demonstration, Zetsubou-sensei cautions that society also misguidedly "revives" various things on the wane. Heedlessly, Manami accidentally revives dead fads and shelved public works, leading to a zombie outbreak. Then, at a wave pool, the class is, one by one, washed away when they submit to the "currents" of peer pressure or sentimentality. Though bemused by their sequacity, Zetsubou-sensei is himself washed away after an enchanted encounter with Tane. He becomes a castaway on an island of nonconformists who resist these "currents", such as outsider artists and the tone-deaf. Then, with the arrival of June, Zetsubou-sensei proposes not only changing to light clothing, but also clothing one's words in euphemisms.
