Yet, the true horror unfolded mere paces away. The supreme villain—cold, elegant, and utterly merciless—stood unfazed before his own younger sister. With a sickeningly calm gaze, he raised his blade. She looked up at him with wide, tearful eyes that mirrored a lifetime of betrayed affection, whispering his name one last time. Without a single hesitation or change in his handsome, emotionless face, he plunged the weapon straight through her chest, severing the last thread of his humanity as her bright life drained away onto the dark earth.
