Miho

Miho, a little girl who dreams of being a fashion designer, lives with her aunt and three cousins while her father is away on business. The aunt, who runs a dress shop, exploits Miho's dependence and makes her perform deliveries on her bike, while spoiling her own daughters. Of the three, the two oldest are cruel and mock Miho's dreams, but the youngest is nice to her. A local disco is holding a contest to find the next "Disco Queen." Miho is too young to enter, but decides to design a dress for her cousin. When the aunt finds out, she rips up the dress. After everyone leaves, two fairies take pity on Miho and transform her into "Fashion Lala," a sixteen-year-old blonde, so she can enter the contest herself. While performing, Miho's outfit changes into her previous designs, and it seems that she wins. At the end, she returns to a happy life with her father~
