9

Nanaka's class plans to do a play for the cultural festival, but when the subject comes up on what to do, six-year-old Nanaka volunteers Magical Domiko. Chie Kazamatsuri volunteers Nanaka to write and direct the play. While looking at some old class photos, she has a lapse and returns to her 17-year-old self. She tells Nenji that she knows she has another self, and asks him which Nanaka he likes more. After Yoshida gives Nanaka some Domiko materials, she agrees to write the play. After being pressured to produce a cast list, Nanaka feels like she will relapse that night. The next day, when a set piece is about to fall on her, she faints and reverts to being six years old again. (Source: Wikipedia)
