EPISODIUM
It's time to hand out grades, but Nozomu Itoshiki hands out completely censored report cards to his students, because he understands that majority of students do not want to be notified of their grades. He argues that people should have right to choose to be 'uninformed' of undesirable information, since they have right to be informed of desirable information. Ultimately, he tries to escape civilization to become 'free' of all the notifications in the world, but he is still in despair as nature are also trying to communicate with him. Meanwhile, Kafuka Fūra is admiring the all-knowing housewife in the neighborhood. In the second part of the episode, Nozomu Itoshiki and his nephew, Majiru, fall asleep together and have a dream where everyone's personality is reversed. The students in his dream realize that they will disappear when Nozomu wakes up, so they try to put him in an eternal sleep by murdering him in his dream. In the third part of the episode, Nozomu and his students discuss various things that are kept secret or unknown from their parents. During this section, the characters are voiced by numerous random voice actors (with most of them from the show itself), and are changed frequently.
