King of Prism by Pretty Rhythm (2016) Plot Summary Explained

Set 1.5 years after the events of Pretty Rhythm: Rainbow Live, the story follows the world of Prism Stars—idols who blend figure skating with song and dance to perform spectacular Prism Jumps. The narrative begins when Shin Ichijō is deeply inspired after attending a performance by the group Over the Rainbow, a spark ignited by a locket given to him by Louis Kisaragi. This encounter leads to Shin being scouted by Hijiri Himuro to train at the Edel Rose Academy.

Upon joining, Shin discovers that the academy is struggling; following the death of the previous chairman, most students and funds have shifted to Schwarz Rose, an institution managed by Jin Norizuki. While adjusting to school, Shin forms bonds with the members of Over the Rainbow: Kōji Mihama, Hiro Hayami, and Kazuki Nishina. The trio shares the importance of friendship in their success, though they face new challenges. Kōji eventually accepts a music production job in Hollywood to help clear the academy's debts, while Hiro sets his sights on the upcoming Prism King Cup.

Tensions rise when Kazuki Nishina is confronted by Taiga Kōgami and Alexander Yamato, who criticize him for abandoning street-style performances. This leads to an intense battle using the Prism System technology developed by Kakeru Jūōin, though the duel ends in a stalemate.

As Over the Rainbow disbands during a farewell concert, the future of Edel Rose seems bleak. However, Shin Ichijō delivers a powerful performance of the song "Over the Sunshine!" alongside Hiro and Kazuki, reinvigorating the student body and the audience. While Edel Rose finds new determination to survive, Jin Norizuki and his students, including a surprising Louis Kisaragi, vow to defeat them at any cost.
