In Zawame City, a large company known as the Yggdrasill Corporation transformed the once bustling suburban city into a jōkamachi. To escape the resulting feeling of oppression, many of the youth in Zawame formed dance crews called Beat Riders to bring joy back into peoples' lives. Also rising in popularity is the Inves Game, a simulator that uses strange devices known as Lockseeds to summon monsters known as Inves. Kouta Kazuraba, a member of the dance group Team Gaim, tries to find his place in the world while torn between his loyalty to his teammates and his sister Akira's insistence that he starts acting like an adult and find a proper job.
