Mitsuki's debut CD is already being discussed by her producer, Mr. Takasu and her manager. Takasu wants her to sing a pre-written song for her debut, but Mitsuki wants to sing a song with her own feelings in it. Takasu agrees to give Mitsuki three days to write her own song. But, Takasu doesn't believe that she can do it because she is a novice. He talked with Ms. Oshige and told her that they will let Mitsuki sing the pre-written one. In the end, Takasu accepted Mitsuki's song. Mitsuki's 16-year-old self now goes by the stagename: "Fullmoon".
