A special summary episode of the second season of Sayonara Zetsubou Sensei, focusing on the girls that were not introduced in the first Zetsubou Shoujo Senshuu: Otonashi Meru, Fujiyoshi Harumi, Kaga Ai and Mitama Mayo.

Valentine's Day has arrived and Nozomu is rather popular. Wondering if this is a honey trap, appealing to a man's desires to obtain secret information, he is introduced to an elite group of otakus, whose disinterest in real women allows them to carry top secret information without falling into the honey trap. Nozomu then ponders about the violent nature of unaired battles, before Chiri discovers his unaired training. Later, Nozomu goes to a halloween party only to find his ideals about Halloween are much different from current ideals, and dwells upon things not being like the original.

Nozomu is paying a visit to Chiri's house after going through various scenes, but his home visit abruptly ends when he reaches Chiri's house. Chiri argues that Nozomu's visit was pointless, but Nozomu points out that most Japanese people take the process more seriously rather than its result. As a typical shōnen manga puts emphasis on the character's development throughout the story, Nozomu asks his students to appeal the audience by showing off development of their immaturity. In the second part of the episode, a warning of earthquake disaster is published by the Ministry of Prediction, which makes every characters except Chiri very lazy as they believe they are not going to make appearance in the magazine. Meanwhile Nozomu points that many Japanese put efforts into various activities despite being aware there won't be any reward for their action. A number of Nozomu's students ends up doing improper conducts as they don't expect themselves to appear in front of the audience. In the third part of the episode, the students are worrying about the dropping interest of book-reading among students. Nozomu thinks that many books should change their titles so that they accurately reflect the content of the book as many books betray the readers' trusts by having inaccurate title. Thus, Nozomu asks Kino and Kudo to give more appropriate names for various books by holding a book-titling competition.

In a Book of Folktales, it shows how Nozomu, first a positive, normal person as a student, is forced to become the negative man he is today.

The class is learning how to properly use the AED, but Nozomu tells that the Dysfunctional AED (DAED) is the one which everyone should avert. The DAED, in fact, has the task to revive dead things which should remain dead. Ohkusa, anyway, decides to pursue her instincts and starts reviving everything she faces, until resurrecting the deads as zombies. The class, fleeing from the horde of zombies, gets trapped in a store, but Nozomu anyway has been bitten. In the second part the whole class is at the pool and gets washed away to the Island of Those Who Don't Go with the Flow. In the third part Nozomu talks about Doublespeak, in other way the act of disguising words with softer ones.

A new special episode that was distributed to those who purchase all three Blu-ray box sets of Sayonara Zetsubou Sensei series on January 31, 2012.
