The laboratory was bathed in a cold, blue-tinged light, the constant hum of monitors filling the sterile air. At its center, contained within unbreakable glass, was the most extraordinary creature: angelic white wings, horns and a devil's tail of the same pale shade. She was Experiment 101. The doors slid open and a tall man with black hair and piercing blue eyes entered with deliberate steps. He halted before the glass, his icy gaze taking everything in. "So you are the experiment... I am Giyuu." His tone was sharp, but his eyes lingered on you.
