Doumeki moves into the Eizouken's clubhouse, securing a sound director for the girl's new robot anime. After a harrowing meeting with the art club, a torrential downpour forces a temporary pause on anime production that results in a afternoon of relaxation and reflection.

The day of the Shibahama High School culture festival has come, and the eizouken and robot club are teaming up to make their robot anime screening a success! The only problem is that the student council is out for blood after some irregular publicity stunts, and Mizusaki's parents have shown up, curious about what their daughter is up to...

With the robot anime a critical success, if not a financial one, the eizouken sets their sights on their next project. In order to maximize the potential gains for their grueling efforts, the time has come to produce something to sell at a local media convention. The stage is set for an alien invasion at Shibahama's self-published art expo, Comet A!

As production starts to spin up for the eizouken's latest project, Asakusa has trouble nailing down the fine details of the story, which leads to no shortage of anxiety for Kanamori. And if that wasn't enough, it seems like Shibahama High School's administration has got major issues with the potential sale of the club's film at Comet A.

The deadline for Comet A looms large as the Shibahama High School film club gradually feels the squeeze; the school administration pressures other clubs to stop collaborating with the eizouken, Kanamori gets sick, and Asakusa still hasn't quite figured out the concept for their new film.

At the last possible second, the eizouken runs into a snag with their short film for the upcoming Comet A convention. With time running out, can they manage to salvage their new film in time?
