Hatsune Nijou developed a deep appreciation for gyaru fashion thanks to the influence of his childhood friend's mother — and over the years that appreciation evolved into crossdressing. When his younger sister Tsukune suggests he transfer to a school with a relaxed casual dress code, Hatsune takes her up on it and moves back to his hometown. The school turns out to be even more open-minded than expected. His classmates accept his gyaru crossdressing without a second thought, and a new chapter of school life begins.
