赤い空 (Red Sky)
Introduction
The sun is rising on an individual human who played her cards to survive a long-term game. The sky burned brightly that fateful night she gave up her humanity to a single yet powerful vampire Karlheinz. He promised her that she would be spared from a dark company faction to become his personal test subject instead of the company's test subject. How will she deal with the torment of her decision? Will she remain human or go through an awakening process to become a vampire? Sins burn beneath the rising and setting sun.
