In the anime's story, a comet falling will bring about a great calamity, and in order to choose a child fated by the falling comet, the family of the "Reiken" clan with a long storied history is once again resuming its entrance examination process to find disciples. The protagonist, who possesses a special soul that is only available once in a thousand years, decides to take the exam, and he starts down the path toward becoming an exceptional sage.

Hoshitani Yuuta enters Ayana Academy, a school focusing on show business activities, specifically music. The academy has a group of three students with the highest grades in the musical department, and they are known as the Kao Kai (Cherry Blossom Flower Association). This organization stands at the top of the pecking order within the academy. The shortcut to entering the musical department is to enter the Star Frame class, which is directly taught by the members, and to be recognized by them. Unfortunately, due to their own problems, students Touru, Kaito, Kakeru, Shuu, and Yuuta are all struggling to even remain candidates for the musical department. By a stroke of luck, however, the five are spotted by Kao Kai member Ootori, and they attract his interest.
