Gushing over Magical Girls follows Utena Hiiragi, a girl who has spent years admiring Tres Magia, the trio of magical girls who protect her town. To Utena, their public battles in the name of justice represent everything heroic and dazzling about the world she wants to believe in, and her fascination deepens when a mysterious black mascot appears with a seemingly impossible offer: the chance to become a magical girl herself.
The promise turns out to be a trap. Utena is pulled into the ranks of an evil organization and forced to fight the same heroines she once idolized. What should have filled her with shame instead awakens a darker thrill, and each encounter pushes her farther from the ideals she once cherished. Rather than recoiling from the violence, Utena finds herself enjoying the pain she inflicts on Tres Magia, and admiration slowly mutates into a sadistic obsession.
Set against the clash between a self-styled villain and the town’s magical defenders, Gushing over Magical Girls builds its story around Utena’s growing fixation, the uneasy appeal of her new role, and the escalating conflict between devotion and corruption.
