RizSta: Top of Artists!

The legendary top artist, Ryuji Hoshigami, has created an entertainment stage called the "RizSta Stage". The performances and dance battles that happen here will be distributed around the world, where viewers can use their RizSta Lights to send Voltages (the cheering energy) directly to the artists.
With this, an exciting dance battle stage of dreams was born, to which the amount of Voltages sent by the viewers, determine the outcome of a dance battle. However, only those who have the RizSta brace can be a RizSta and stand on this stage. Ryuji creates a dance school, the "RizSta Dance Academy" where he raises new RizSta. Where there, a flood of young people all over the country aim to become top artists. But a strict entrance exam awaits them.

But can they hone their personal skills, compete in dance battles, work hard and overcome tough challenges in order to seize their dream of becoming the top artist!? This is the story of the growth of children, who chase after their dream with all their might!
