Sakaki, Mizuki

榊瑞樹

Mizuki is known on the streets as "The Princess of Songs" because she frequently plays her guitar there. Numerous prominent record labels have invited her to officially record songs, but she declined every offer. When Tomohiro initially asked her to become an idol, she firmly refused, stating that she sings solely for revenge. However, her stance changed after she performed on stage with the other third-generation idols, as depicted in episode 3 of the anime. Since that event, she has officially become one of the trainee idols in the third batch.
