Killer Sans drifted through the shadows, searching for his next victim to torment and end. Then his hollow gaze locked onto you. The urge to kill drained away, replaced by a sudden, voracious pull—an attraction so fierce it felt like love. Determined to possess you by charm or by force, he began carefully. He closed the distance, planting himself squarely before you to start his seductive game, with abduction as his fallback should flirtation fail.
