Aoi is panicking a little at the fact that episode four is a little behind. She manages to enlist the help of Endou, the animation supervisor for episode three, and is able to stabilize things a bit. However, as soon as one hardship leads to another. While at the episode four dubbing, Aoi is present when the director and animation director are discussing retakes. The director is moved by one of the voice actor's performances, and starts talking about the scene not being right.

Aoi heads to work flustered, as she finds out that her older sister is coming to visit. When she gets to the office, she finds out one of her seniors is leaving the company, and Aoi is shocked. Aoi goes to get the key frames from Ema while there's a lot on her mind.

A meeting about "Third Aerial Girls Squad" was happening at Musashino Animation that day. Various people were trying to push their own talent based on everything other than talent.

Episode 1 of Musashino Animation's Exodus! Akane, Aya, and Arupin, the members of the idol group Tracy, stage a performance at a supermarket, but no one stops to listen to their singing. As the girls redress into maid costumes inside bathroom stalls, Arupin remains optimistic of the reception, pretending the trio is living perfect lives as idols instead of being employees at the supermarket. However, she is scolded by Akane, who chastises her for not facing the reality of their situation. After comparing the dismal number of their fans to the fanbase of a rival idol, Ginger, they receive a call from a woman they call their "Onee-san", who praises a performance video they sent her. The girls then eat some manjū, which inspires Akane to speak to the trio's manager, Taguchi. Arupin follows her, but loses her and then finds Taguchi lying dead in a pool of blood. At the crime scene is a bloody knife identical to the ones the girls kept as part of their costumes, along with a partial message written by Taguchi with his blood, beginning with the letter 'A'. Shortly after, Akane and Aya stumble upon the scene as well, then all three are spotted by a man, who assumes they murdered Taguchi and alerts security. The girls then receive a call from Onee-san on Taguchi's cellphone; she instructs them to flee. Taguchi's murder is assigned to Inspector Miho Koigakubo, who declares the girls wanted criminals. Near Musashino Dome, Akane reveals her dream to sing in Musashino Dome in front of a crowd of fans. They then receive another call from Onee-san, who informs them that they were identified as murder suspects and their fanbase skyrocketed as a result. Seconds later, they are spotted by a fan and retreat to a basement parking lot, where they find a motorbike supplied by Onee-san that they use to flee. After stealing a policeman's revolver, the girls managed to evade police on a boat, although they wind up losing their makeup in the process, surprising them as they had never seen each other before without makeup.

Things with "Third Aerial Girls Squad" gets rather busy for everyone at Musashino Animation. Iguchi suggests that Ema should be the supervising animator assistant on the final episode, which makes Aoi really happy, but Ema herself seems to lack confidence.

Finally, the time has come to deliver the final episode of "Third Aerial Girls Squad." Will Aoi and the others be able to get them delivered to all of the stations in time for broadcast?
