At Sound Team Don Juan Studio, Futaba meets Ryoko Shiraishi. Futaba thinks that she's really pretty. Futaba learns that Ryoko can do both boy and girl sounds very smoothly and also learns that Ryoko has some of the boy personality too. While recording the dry run, because Futaba focuses on the work too much, it make her cough. After that everyone worries about Futaba's throat and give her advice about it. Ryoko advises her to take as many cough drop sweets, put a face mask on and go to sleep. She also tells Futaba to take care of herself. Futaba has a problem about her role while taking a bath, making her stay in the bathroom for too long, which later causes her to have a cold and fever.
After Futaba's recovered and done the recording, she walks back home with Ryoko. Ryoko asks her about Earphones Unit, which reminds her of when she was in another voice actress unit. Futaba thinks that unlike both Ichigo and Rin, she needs to work hard so she doesn't drag them down with her. Ryoko now realizes the reason why Futaba was overdoing work. She tells Futaba that she once had vocal cord nodules. She was focusing too much on her work and made it worse, so she needed to get surgery on her throat. It was uneasy but she decided to take surgery in the end, because she wants to be a voice actress for the rest of her life. Her speech makes Futaba realizes something she nearly forget; that she also wants to be a voice actress for the rest of her life too. She just needs to go at her own pace. Suddenly, Ichigo and Rin call to tell her about the solo concert that Kaibara-san has decided to hold for their unit.
The next day, Futaba, Ichigo, and Rin find out that their concert ticket sales are 12 from the 500 available seats. They decide to promote and advertise more about the concert. Kaibara-san also tells them that since they currently have 3 songs, which is not enough to hold a 2 hour concert. They decide to covers songs, but because of the budget, the three of them need to do the choreography by themselves. After promoting in many ways, only 52 tickets were sold. So Kaibara-san decides to make the unit promote their concert at the Anisong Autumn Concert. First, Futaba, Ichigo, and Rin think that they will have the time on stage, but the truth is they only have to hand out flyers in front of the concert halls. They still end up filling their concert hall with 200 people in the end. After hearing the news about the seating, Ichigo accidentally sprains her ankle while practicing. What will happen to their concert?
