Shinka decides to run for student council president, but her candidacy campaign proves difficult due to Sanae constantly interfering. Later, it is also revealed that Satone had gone to the same middle school as Shinka and was well versed in her identity as Mori Summer. Sanae, now convinced that Shinka is the genuine article, starts acting more polite and affectionate towards Shinka, who has her help out with her election campaign. However, this soon turns out to backfire against Shinka when Sanae uses notes from her chunibyo days as an endorsement speech. As such, Shinka fails to get elected and Sanae goes back to believing she is a fake, bringing their relationship back to the status quo.
