Each Other's Existence! Asakusa continues to struggle thinking up a story for the anime, while the Security Club forcibly shuts down another school club working with Eizouken to copy DVDs before they can get to work. The Eizouken advisor plays handheld videogames and encourages the club to relax for a bit. Asakusa and Mizusaki decide to goof off near a waterway in town, and Asakusa falls into a river before Kanamori drags her out. All the while, the trio are tailed by Doumeki as she records the sounds they make. The next day, the school's Vice-Principal cuts off Eizouken from the other clubs. Asakusa and Mizusaki take a train to visit a sick Kanamori at her home, and Asakusa flashes back to when she first met Kanamori in middle school. They were both loners for different reasons, but formed a codependent relationship. While visiting Kanamori at her sickbed, Mizusaki tells Kanamori about the situation, and Kanamori shows that their efforts have generated enough media coverage that the school would only embarrass themselves by shutting down Eizouken's project. Then Asakusa reveals she thought up a story that tied all her previous wanderings together about a war between humans and kappas. With this new direction, Eizouken comes closer to finishing the anime, but Doumeki later reveals that something or someone replaced the entire audio track with a strange piano tune.
