The two high school girls, Hanazono Mito and Tatsuda Seshiru, have been friends since kindergarten. But while Seshiru is an honour role student, Mito is constantly breaking school rules. One day, Mito helps Seshiru evade the advances of the arrogant Ran, a rich boy and model who mistakes Mito's interference for jealousy (because of course every woman wants Ran for herself! Yeah, right). This lands Mito in hot water with Ran's fangirls, who later gang up to kick her ass! A new transfer student with wild hair is the one who saves her, but he won't tell Mito his name…!?
