Tiara, a princess from the kingdom of Waleland, journeys to the city of Mamkestell to enroll in a prestigious academy for magic practitioners like herself. After passing an eligibility test, Tiara reunites with her childhood friend Rosetta, who is also a student at the school. She then joins Rosetta's group, meeting the athletic Lavie, the dependable Ashley, and the studious Lynette, all of whom Tiara quickly befriends. At this institution, students are assigned to one of three ranks based on their test scores: Noir is the highest, followed by Rouge and Lapis. Tiara's group is placed in the Lapis rank, and if that were not enough, those who fail while in Lapis face expulsion. Recognizing their precarious position, Tiara urges everyone to take their activities more seriously. Additionally, Tiara has another reason for striving to excel at the academy: to become more like her elder sister, a highly skilled singer. However, to reach the stage she desires, she must overcome numerous challenges alongside her companions as she continues her magical journey.
