Summary:

Average sixth-grader Nina Natsukawa is the top student in her class, and infamously unfashionable. Secretly, though, she's always longed to be stylish and cute. One day she buys some trendy clothes and tries them on in private... or so she thinks. A classmate of hers winds up catching her on film, and says he'll spread the photo around to their entire class unless she becomes a model!
