第 12 集: 文化祭活動導致班級分組、卡拉OK，以及珍貴的友誼。
At the festival, Najimi decides to use shady tactics in order to attract more customers. However, they are caught and forced to provide refunds. Komi, Tadano, and Najimi later visit a haunted house and the school's rooftop confessions before Najimi is dragged away by the meditation club. Komi and Tadano then hang out with Onemine and Otori by visiting the various stalls and activities. In the gymnasium, Komi's class is announced as the winners of the festival. However, thanks to Najimi's actions, they are not awarded the grand prize. Everyone later gathers for the dance party. Komi wishes to dance with Tadano, who nervously tries to lead to the way. They are then joined by an enthusiastic Najimi. After the festival, Komi's class head to a karaoke bar. There, Komi receives praise for her singing, even though she was too nervous to actually do so. When it is Tadano's turn, he is ignored by almost everyone except Komi, which gives him the motivation needed to finish. Later at her house, Komi cherishes the friends she has made so far.
