Mizuki is known as "The Princess of Songs" on the streets, as she often plays on the streets with her guitar. Many famous record companies have asked her to officially record some songs but she turned them all down. When Tomohiro first asked her to become an idol, she strongly refused and said that she only sings for revenge. However, this all changed once when she first sings on stage with the other idols of the third generation, as seen in episode 3 of the anime. Ever since then, she officially became one of the idols in training in the third batch.
