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 reference to a piece of literature. Each episode ends with a still image drawn by one of manga artists associated with Kōji Kumeta. These are listed below as endcards.

Chie dispatches Nozomu to investigate rumors that the invariably injured Abiru Kobushi is suffering from domestic violence. He pursues Abiru's father while he shops, causing him a great deal of inconvenience, before discovering Abiru's obsession with pulling the tails of dangerous animals. The latter half of the episode concerns Meru Otonashi, who is silent and shy in person, but remarkably abusive via text-messaging, her only means of communication.

On physical examination day, many of the girls are feeling stress about their weight, measurements and fitness. Nozumu distracts them by deciding to judge the "social worth" of students so that they will know whether they are living "above their station". Chiri seizes on this idea, scolding everyone who possesses any luxuries, appalling Nozumu to the point where he decides to go on a hedonistic binge before killing himself. In the second half he encounters some of his students at a hot spring and is frightened to learn the spring has the power to remove their "toxicity", giving them well-adjusted personalities.

This episode begins with Harumi Fujiyoshi bumping into Nozomu while she is on her way to make copies of her dōjinshi for Comiket. Harumi tells him about her hobby, but Nozomu misunderstands, thinking of dōjinshi in the literary sense rather than in the manga and anime sense. At Comiket, Chiri confronts Harumi about the structure of her dōjin, demanding that she redo it in the yonkoma format of Kishōtenketsu; this leads to Nozomu adding a fifth panel to the standard form. The second half of the episode involves the girls at a matsuri, where overzealous festival-goers begin piling random objects and people on portable shrines and dancing and parading around with them.
