Haneru Tobitatsu is a hyperactive middle schooler with a passion for dancing. Inspired by his idol Jey El, the hottest star in the world of dancing, Haneru practices outside Memorial Hall every day after school. Unbeknownst to him, his "secret" practice sessions are being watched by Kanon Otosaki—her true identity being the famous online dancer, Rhythm—who also frequents the same location for practice. When Haneru finds out about this, he shows an immediate interest in teaming up with her.
Slowly realizing the joy of performing with others, the duo makes their way into the world of street dancing, where they meet Kumonosuke, Mizuki, and Yuzuru, ultimately forming the dance group "Tribe Cool Crew." As they face off against tough competition, they strive to one day realize their dream of sharing the stage with Jey El.
