Gals Fiction THE ANIMATION

Hatsune Nijo's tastes were thoroughly warped by the influence of a childhood friend's mother, leaving him with an intense obsession with gyaru fashion and culture. Years later, his fixation has only deepened—to the point where he begins cross-dressing to embody his ideal gyaru persona himself.

One day, he receives a message from his younger sister, Tsukune Nijo, who tells him that her school recently started allowing students to wear casual clothes. She suggests he come to school with her, embracing his obsession. Unable to cure his twisted fixation, Hatsune decides to live life on his own terms and transfers into the school, starting a new school life alongside gyaru girls who fully accept and celebrate his cross-dressing alter ego.
