Hitohira

Mugi Asai, a young shy girl entering high school, is unsure on what clubs she should join. After she accidentally displays her loud vocal skills due to an excited outburst, the president of the Drama Research Society, Nono Ichinose, comes to her to ask her to join her club. After some minor pressure by Nono, Mugi signs up for the club, but is still unsure what this will entail.

Mugi attends her first meeting with the Drama Research Society and finds out there are only five members including herself. During this meeting, she finds out that she will inevitably have to act in an upcoming play that the club will put on, something that Mugi is unsure she can handle. The following day, the Drama Research Society are practicing on the roof of the school, and Chitose Kanna from the Drama Club comes to help them.

The Drama Research Society's first public performance is coming up, and Mugi is nearly petrified to appear on stage. Nono manages to get Mugi out of a bathroom stall she had locked herself in, and then the club starts to hand out fliers to promote the event. During dress rehearsal, Chitose bursts into the auditorium and asks if Nono really is suffering from a latent form of vocal cord paralysis, and this is confirmed by Nono herself. During the play, Nono calms down Mugi enough for her to go on stage and she manages to get through her lines well enough.

In class, Mugi is contemplating on skipping on club activities and wonder if she can become a delinquent. Nono and the other members of the Drama Research Society arrive and take her and Kai Nishida, Risaki Nishida's younger brother who is in the same club, out for some exercises in the school yard. After a small confrontation between Nono and Mirei Sakaki, the Drama Club president, Nono bets her club's funds that each of her members will get in the top fifty place for their upcoming midterms, which is later increased to top thirty. The Drama Research Society thus has a study session together where Mugi learns more about the club's past with the Drama Club.

Summer has arrived and Nono decides to take the Drama Research Society on a little trip to the beach for their practicing session. The moment they arrive they begin to practice, and Nono explains that since they do not have much time, they must train as much as possible. Late on the first night at the beach, the club is practicing their lines from Nono's script, Hitohira, and Nono informs Mugi that she is to be the lead actress. Mugi thinks this is impossible for her which leads Nono to tell her to leave if she thinks she cannot do it. Mugi leaves distraught and Kai goes to run after her. Meanwhile, Risaki is angry about what Nono said to Mugi and cannot hold back her rage any longer, resulting in her punching Nono in the face; the two of them get into a fist fight.

The Drama Research Society is still away during their summer practice session, though things have gotten complicated. Risaki and Nono are still fighting, and Mugi is still unsure about whether she should quit or not. After thinking about it, however, she decides not to quit the club. Mugi goes to Nono and apologizes for what she said earlier to her, namely that Nono can do everything she cannot and it would be impossible for her to act as the lead actress. The rest of the time is spent practicing for the play and playing with fireworks. After summer is over, Mugi's personality has changed slightly and she is more confident than before.
