Long ago, Hatsune Nijo awakened to a love of gyaru style at an early age. As a result, after he tagged along on his parents’ long-term business reassignment and moved away from his hometown, he eventually began cross-dressing as a gyaru.

One day, his little sister Tsukune suggests that he transfer to her school, which had recently started allowing students to attend in their everyday clothes. And so, Hatsune resolved to return to his hometown.

However, the school turns out to be even more free-spirited and lax than he could have imagined. And thus begins Hatsune’s new school life, together with open-minded friends who accept his gyaru ways!
