Suddenly, Nozomu releases a mysterious wave that reveals the dark side of the world, which is full of despair. Finally, Perry learns the lesson that he shouldn't try to open up everything in the world. However, all the characters speak unintelligible gibberish, and the subtitles suggest that Perry is Son Goku looking for the Dragon Balls and that Nozomu is an alien bent on stopping him. In the next part of the episode, Nozomu is complaining about the over-decoration of various things in Japanese society. However, Kafuka Fūra denies it, saying that it is just a trend among stylish elites. In the next part, Nozomu meets his old time friend Ikkyū-san, who likes old things. They discuss together how old things are often ignored in modern Japan. Ultimately, he wants to obtain a former-surname by marrying Nozomu's sister Rin.

Nozomu Itoshiki hands out an application for his pension in a government office, but an employee makes fun of Nozomu's name. Nozomu is sick of hearing the same thing about himself over a million times and he sympathizes with other people, who have experienced a similar situation for countless times in their life. Meanwhile, Harumi Fujiyoshi realizes that she is an extreme minority as no one seems to agree with her view.

The café manager kindly asks Nozomu to forgive him, because it is generally believed that exam-preparing students should be treated with the utmost care. Though Nozomu can't quite understand this kind of expectation in the Japanese society, he nevertheless tries to take advantage of this trend by becoming an exam-preparing student himself. Eventually, he happens to pass every certificate exams in the world except for one: an exam that tests whether a person is ready enough to commit suicide.

Nozomu points out that some people use 'detuning' as an excuse for their faults, Kafuka explains that people in general feels more comfortable with 'detuned' products rather than the cutting-edge one. In the second part of the episode, Nozomu states that there is an increasing tendency of saying 'not bad, not bad' at terrible things to comfort the victims. However, Nozomu explains that such instance can turn out to be a 'mini-propaganda', which could unknowingly mislead other people to believe in the same way. In the third part of the episode, Nozomu refuses to teach the first period class, because he was previously rejected by a restaurant in Kyoto as he was a first-time customer.

Ultimately, he decides to also reject the regular audience from the show.

After dismissed from the school as a demon, Nozomu Itoshiki wonders where the devils will end up once they are dismissed from everyone. Nozomu suddenly argues that dismissed people should be provided with a new employment after their dismissal, otherwise dismissed people will end up being 'wild' people in the street. Nozomu's students brings various wild people to his house and ask him to take care of them. Nozomu flatly refuses the offer, but he cannot help but to take care of them.

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.

During a walk, Nozomu gets deceived by Maruuchi Shoko and Nedu Miko, who sell him maguro and a block of ice for 15.500 ¥.

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.

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.
