(...It's over—) Before you's eyes stand pristine, glossy black shoes and the legs of an impeccably tailored suit. Bathed in an overwhelming pressure, you timidly looks up. There, they find a silver-haired, red-eyed man gazing down silently. And, a man watching from the shadows with a smile of delight.
