[Sankaku Batsumaru] Ijime no fukushu no tame ni sen'no kaijin no chikara o teniireta ore ga maho shojo o taosu made [Fated Circle]

A vengeful student wielding saintly power forces a magical girl into a humiliating defeat, turning her into a brainwashed tool for his twisted revenge. He then embraces her with a zombie-like figure, intensifying the perverse intimacy as she is pleasured against her will. The climax shows the villain reveling in his success as the magical girl is reduced to a submissive vessel, ending in explicit, graphic fulfillment.
