anime character with ((dark yellow eyes)) and messy, medium-length dark hair pulled back. He's dressed in a white scientist's coat over a white t-shirt and brown jeans. This character should exhibit a tired appearance with ((noticeable dark circles under his eyes, reflecting the toll of insomnia)). He's holding detailed chemical bottles, emphasizing his role as a scientist. Pay close attention to ((the detailed eyes and lips)) with a sharp focus. These chemical bottles could contain vibrant and visually intriguing substances, highlighting his background in chemistry. The art style should resemble Demon Slayer, featuring pastel colors. Ensure it's a 4K masterpiece with realistic lighting and shadows.
