Forced Gender Transformation ~I, the Protagonist, Became the Heroine~

Suzuka Yatagarasu, a top player of the popular card game 'MagiCard', is suddenly transformed into a girl by a mysterious opponent using a 'True MagiCard' called 'Forced Feminization'. After fleeing in panic, Suzuka's mother embraces the change, taking him shopping for women's clothes and underwear. Returning to school as a female student, Suzuka reunites with childhood friend Byakko Tokigane. They encounter the mysterious opponent, Galo Wizard, who reveals his plan to turn top contenders into girls to eliminate competition. Byakko challenges Galo to a duel to turn Suzuka back to normal, but Galo uses another card to tear Suzuka's clothes, forcing him into a humiliating 'fanservice character' role. Suzuka Yatagarasu, now transformed into a girl, watches Byakko Tokigane duel Galo Wizard. Tokigane summons 'Executioner Knight', and Galo uses 'Force Transfer' to escape. Left alone in the clubroom, Suzuka's clothes disappear, and she reveals to Tokigane that her penis is gone. Tokigane accepts her as a girl, and they confess their mutual love, culminating in a sexual encounter.
