As Mahiru is offered her own regular feature in a fashion magazine, she comes across two rude ganguro high school girls, Motoko and Eiko, scolding them for littering. The next day, the girls and their leader, Sumiko, come to Mahiru for advice on how best to wear make-up. With her various hair and make-up tips, Mahiru manages to help the girls show off their true beauty without excessive products. As Mahiru becomes inspired to use her magazine feature for make-up lessons, she further trains the three girls to be her models at a fashion show showing off their transformations.
