Mahou no Stage Fancy Lala

One day, nine-year old girl Miho Shinohara is given two stuffed dinosaurs by a stranger. The stuffed dinosaurs come to life and present her with a magic sketchbook and a pen. Within limits, and subject to varying degrees of control, she can draw in the sketchbook and bring the drawings to life. Miho can also transform into a teenage girl, whom she names Fancy Lala. Fancy Lala is scouted by Yumi Haneishi, the president of the talent agency Lyrical Productions, and begins the long road to stardom.
