The Great Cosplay Plan!

Kazuto and Narue are supposed to go on a date together, but Kazuto instead goes to a cosplay expo, which features Kiriri Kaibashira, the voice actress for Magical Girl #4. Kazuto is overjoyed to finally meet Kiriri in person, but Narue becomes fed up, especially due to Kiriri's snotty attitude towards her, which causes her to walk away. Narue has no one else to turn to until she finds Yagi, who helps her research about cosplay. The two later cross paths with Kiriri, who tells them about an upcoming cosplay contest in the weekend, mentioning that she invited Kazuto to participate as a judge. This encourages Narue to enter the contest and make her own costume, with the help of Yagi, to impress Kazuto and to show Kiriri up. Meanwhile, Kazuto feels that Narue has been avoiding him for the past few days, giving him much concern. As time is soon running out, Yagi and Narue beg Maruo to help them make the armor and cannon of the costume overnight. During the contest, Narue makes a stunning appearance on stage and pleases the crowd, but Kazuto faints at the sight of this. He wakes up backstage with Narue at his side. Even though Narue wins the contest, yet does not accept the prize money, Kazuto tells her that he likes her just the way she is.
