A welcoming party is held for two new production assistants, Tsubaki Andō and Sara Satō, while Marukawa announces that Musashino Animation's reputation depends on the execution of The Third Aerial Girls Squad. Afterwards, Tsubaki and Sara join the rest of the staff as they engage in a meeting discussing the ending of The Third Aerial Girls Squad, then a location hunting trip. Later, Seiichi finishes the storyboards for the first episode, albeit with some dubious drawing quality. Production begins on the episode, with shy key animator Ai Kunogi participating in her first production meeting, where she is assigned by Seiichi to animate a scene. Meanwhile, Tsubaki and Satou go with Tarō to pick up some key frames from Kisa and Segawa before attending more meetings pertaining to certain topics, including supervising animation with Yumi, art board with Yūji, color with color setter Nao Shinkawa, CG with Yūichirō, and filming with director of photography Yoshiki Sakura. Aoi and Yūichirō visit Studio Kanabun, Misa's new workplace, where the latter convinces the president, Nobuaki Nakagaichi, to take some of the CG cuts. Later, Aoi assigns Tsubaki and Sara with the production on episodes four and three, respectively, and advises them on how to effectively manage their time. Just as production seems to be going well, Watanabe informs Aoi that they need to stop production when the author of The Third Aerial Girls Squad, Takezou Nogame, has demanded retakes for the character designs, meaning they must start everything from scratch.
