The Greatest World!

As Mizusaki is banned from joining the anime club by her parents, the only way for the three of them to make anime is to set up a new club. At the staff room, their teacher tells them that they will be granted a certain budget if the objective of their club was to create a live-action movie. Kanamori suggest that they will call their club "Eizou (Film) club" and use its name as a disguise. Thus "Eizou-ken" came into existence! They head off to a storage space previously used by the anime club and realized all kinds of treasures behind the door!

Eizouken's so-called club room was merely a storage with holes in all sides. Therefore, fixing the room was a priority. Asakusa imagine the process as spaceship fixing training. To promote their club, they decided to create a new anime to show at the "budget decision committee meeting". Three of them choose a scene from one of Asakusa's many sketches. Asakusa wants to animate a tank while Mizusaki is persistent about actions. With her producer-like vision, Kanamori eggs on their creative energy.

The student council's budget committee looms on the horizon as the eizouken's project is still far from finished. As Mizusaki struggles with effects shots, Kanamori reminds her of the grim reality of the approaching deadline. While Asakusa manages to extend their run-time with creative use of existing art, the club is forced to make hard decisions about what parts of their creative vision to sacrifice and which parts to preserve. But even then, will they have something that resembles a complete product in time?

Asakusa discovers a mysterious robot, and before long Mizusaki and Kanamori are implicated in the conspiracy surrounding it. The nature of that insidious plot? The Shibahama High School robot club commissioning an anime short from the eizouken. After exploring the maintenance tunnels beneath the school, the girls have their first production meeting with the robot club, where they run into the complicated contradictions in the visions of their would-be clients.

Production begins on the Eizouken's new robot anime, and improving on their last work means expanding the club's reach. Asakusa struggles to convey her instructions to the art club, who are going to help with the backgrounds this time around, while a run-in with the student council puts a prospective new ally in Kanamori's sights.

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?
