Midori Asakusa is a first year high school student who dreams of creating her own animation. When she visits a screening event held by Anime Club with fellow student Sayaka Kanamori, an amateur model Tsubasa Mizusaki starts talking to them. As she was being chased by men dressed in all black, Asakusa and Kanamori help her get rid of them. To their surprise, they learn that Mizusaki is also aspiring to be an animator. The three of them hit it off to realize their own "Incredible World" together!

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?

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 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.
