Original title: ブレイブビーツ

Hibiki Kazaguruma, a sixth grader, meets an amusing little robot named Breakin while coming home from school one day. Breakin, a dancer from an alternate-dimension dance world, challenged the Dance King for the throne and lost. He has been deprived of Dance Stones (crystals containing the powers of different forms of dance) and sent to the human world. To restore his power, Breakin must collect all the Dance Stones scattered around Earth.
