Kirisaki arrives at Sainan High School to give a lecture about working as an idol. After the event, Tearju asks Rito to guide Kirisaki around the school which Rito reluctantly agrees to. Rito does not know Kirisaki's main purpose was to observe Rito for a day. As Rito guides Kirisaki through the hallways, he gets unwanted stares from other jealous students. They both come across the principal who initially acts docile but suddenly runs after Kirisaki, making the morals committee discipline him. Afterwards, Morenitsu asks Kirisaki for her autograph and draws the attention of many male students, creating a large crowd around Kirisaki. Rito rescues Kirisaki from suffocation and tries to escape from the other male students. Lala senses danger and uses her invention to teleport them into a locker partly naked. Momo helps recover their clothes, but Kirisaki runs home in embarrassment. The next day, Run tells Kirisaki that she experienced similar events in the past. The memories of Rito carrying Kirisaki come into Kirisaki's mind, but Kirisaki quickly brushes it off.
