Zan Sayonara Zetsubou Sensei

As the school exams approach, Nozomu sniffs at the idea of good luck charms. Just then, he is arrested by mysterious people for being a potential bad luck charm for the students and locks him up in solitary, which he is quite pleased about. However, the girls break in and rescue him, and it comes to light that the students actually see Nozomu as a good luck charm. Next, everyone has different opinions of what tells them spring has come, which for some people involve strange dancing people. Later, Nami tells Nozomu she is going on a trip to find herself, whereas Nozomu says it is really a journey that exposes a person's true nature.

While watching a baseball match, Nozomu wonders about the sad fate of the multi-talented people. If a famous baseball player is as handsome as a model, is he missing a more successful career? Later on, as Kiri is taking some medicine to treat her cold, Nozomu explain to Majiru why did it took a moment for the medicine to take effect : the dreaded time lag, which can be observed in a lot of phenomenon. As the journey to find themselves continues, more of Nozomu's students embarks on the bus and procede to reveal some parts of their personality. In the end, Kafuka leads the group to expose themselves to reality and at the same time the acceptance of their true self as they are, after which she concludes by singing a heartwarming song.

As Nozomu and Kafuka attempt to find the switch to the town christmas lights, Nami finds she keep switching on other people's switches. Next, Nozomu contemplates on how people making a decision between two things subconsciously end up picking a third. He and the girls end up in a third-choice city. Whilst arguing about excessive care, Nozumu is taken by Rin to a Guardian's Club, where people take excessive care measures.

Chiri notices Nami wearing brand new trainers in the rain and gets annoyed when people don't consider TPO (a wasei-eigo term meaning Time, Place, Occassion). Nozomu laments that some people do an incorrect TPO when compensating for another TPO. When ume no hi comes, Nozomu ponders that its not a convenient holiday for prefectures of Japan that aren't next to the sea. The discussion moves onto the morals of celebrating things others can't cheer about. The gang decide to have a 'chimerical holiday', involving as little fun as possible. After escaping from the Excessive Care Guardian's Club, Nozomu finds all his leisure options restricted due to excessive care. He then notices that his body double has been benefitting everyone in his place.

Whilst complaining about how people use poetic words that make you skeptical about them, Nozomu gets thrown into a card game by Rin in which excessive writing is applied to their names. As Chiri complains about the leap seconds added at the new year, Nozomu considers there might be leap people who multiply unnoticed. Chiri is suspected of being a leap person and is enlisted into a parody of the Blue Man Group (in Japanese, blue (ブルー) and leap (うるう) have similar pronunciations). Whilst Nozomu sees Houjoue, a buddhist holiday, as a day for overlooking things, Kafka believes it should be a part of daily life, and introduces him to family that ignores life.

During a walk, Nozomu gets deceived by Maruuchi Shoko and Nedu Miko, who sell him maguro and a block of ice for 15.500 ¥. Nozomu complains that many dealers make up money only after the customers buy the goods, using tricks. The too mild winder is caused by Shogun Frost who refuses to do his work anymore. The class helps him to find a new job. The class prepares a surprise party for Nozomu, even if his birthday is not on that day, but on 4th of November.

Nozomu shows how, in a suspicious society, there is more "reverse-surprise" than surprise itself: people, in fact, are more surprised when they expect things to happen, but they do not, than when they really do. Chiri finds out Nozomu standing in front of a Police box, he tells her that he's training to confess. Modern Japanese people are not able to admit their fault and need this kind of training. Nozomu gets on a train which apparently has no destination. On the contrary everything, even the train, has got a previously decided destination. People, in fact, ask questions about things they have already analyzed and chosen. The 3rd part of the episode has been made with an experimental graphic technique.

Whilst waiting for the bus, Nozomu and Chiri talks about how important are emergency measures in one's life. Later, at school, the class finds out Nami's birthday, but, because nobody knew about it, everyone makes her a sudden emergency present. Nozoumu, correcting some tests, shows the class how, in the adults' world, there are correct but not right answers. While the class is playing golf, Nozomu's sister tells them that a new course has been created in town. In this new kind of game the balls are represented by people and the tees are disguised as objects or places they have to keep away from as long and as far as they can.

Grabbing an easter egg, Nozomu wonders if came first the egg or the chicken, the panties or the panty-thieves, hope or despair, and so on. Being in a queue clogged up by a woman who's seeking for changes in front of the counter, Nozomu notices how Japan has become the Paradise for spies who try to wreak havoc among the population.

Nozomu says that a ghost stole his glasses so the class decides to buy him a new pair. The glasses he gets are tinted and make Nozomu be filled with prejudice and hatred about everything. Rin is home and bored but, because she cannot leave her estate, in order to get the near ramen shop she buys and destroy all the houses on the way. During sport time Nami lifts her leg in order to gain males' attention, this makes Nozomu think about people provoking with intention.

It's Valentine's Day and Kagerou is afraid to open his box, because he doesn't really know whether any girl had dedicated a love letter to him or had not. Nozomu tells hit not to open it, in order to create a Schrodinger's box, in which the possibilities of the presence of any letter and the possibilities of absence are both infinite. A missile drops on the school's field and the class tries despairingly to hide it. An interviewer is, in fact, going to come to the school. After purchasing all the houses and getting the ramen shop Rin notices how the flavour has changed because of changing of her new management.

When Chiri hangs up a painting upside down without noticing, the class are taken through a gallery where involving big mistakes that go unnoticed compared to the minor details. In the second part, Nozomu accidentally causes Kiri's blanket to fly away, and the class go on a search for it. However, it flies onto a government member who decides to mass produce it so people will feel more secure. Soon everyone decides to become civil servants and the world becomes impoverished. In the third part, Nozomu and company discuss buzzword generals and are disturbed by one. Maria then mentions "Kiyohiko's Night" (a mispronunciation of Silent Night) and a Kiyohiko shows up, but is unprepared for the abrupt pun.
