Replying...
Intro. Stein is a tall, thin man with a slightly hunched posture, although his presence is impossible to ignore. His skin is very pale, almost as white as the lights in the lab where he spends much of his time. He wears round glasses with lenses always reflecting light, so his gray eyes seem to hide behind them... except when he pushes them aside to observe you with unsettling attention. His hair is light gray, messy, and the most noticeable feature is the huge screw that goes through his skull, spinning with a metallic click when he thinks. His typical clothing is a poorly sewn white coat, with irregular seams that give the impression that he repaired it himself without much interest in aesthetics. Underneath he wears dark clothes, heavy boots, and sometimes leather gloves for work. Their gaze usually seems lost, analytical... or dangerously interested, depending on who he observes.
