Kumiko and her teammates have won the Kyoto regional tournament. From now on, life will be getting a lot more hectic. With the national tournament fast approaching, Kumiko's band is doubling down on practice and discipline, leaving little time for sleep or other recreational activities. The redoubled practice schedule brings Kumiko and Reina closer together, but elsewhere in the band, it seems like drama threatens to tear the group's unity apart. The ghost of the prior year's mass band exodus still haunts many of Kumiko's classmates, and with former band member Nozomi Masumi now asking to return, it seems like the grudges of the past will soon be impossible to ignore.

First-year high schooler Midori Asakusa loves anime so much, she insists that "concept is everything" in animation. While she spends her time doodling endless ideas and settings in her sketchbook, she hasn't taken the first step to creating anime, insisting that she can't do it alone. After Asakusa's money-loving best friend Sayaka Kanamori notices her genius and drive – and when it becomes clear that their classmate and charismatic fashion model Tsubame Mizusaki wants to be an animator – the energetic trio start an animation club. Together, the three aim to realize the "ultimate world" that exists in their minds, as they come to see the power that fiction and imagination have on their lives and the world around them.
