Nozomu Itoshiki and his students enjoy the festival of Tanabata and talk about instances where people pay more attention to the trivial details of many objects rather than the main subjects. In the middle of their conversation, which Ikkyū-san later joins, the alien race El Niño suddenly invades Japan with their mecha army. Fortunately, Chiri digs up an ancient mask and activates its hidden power to defeat the alien force. The aliens admits their mistake of paying attention to trivial aspects of Nozomu's students rather than the progress of their invasion. At the end, Nozomu and Ikkyū-san do not remember how Japan was saved from the alien invasion, as they were paying attention to trivial details of the battle scene. In the second part of the episode, Jun Kudō is reading books in the school library, while Nozumu is worried about Jun's desire to read everything in the world, which could eventually include Nozomu's own embarrassing mind. When Nozomu's other students visit the school library, Jun tells heart-warming stories that move every one of them to tears. Nozomu feels even more certain of Jun's ability to read people's minds, so he puts himself in a freezing room full of penguins to prevent Jun from reading the conclusion of the episode. The third part of the episode shows what happened between Nozomu's nephew, Majiru Itoshiki, and Kiri Komori while the alien invasion of the 'A Painter by the Roadside' episode was undergoing outside the house.
