A medium shot, front-facing illustration of Eru Yorukami, a calm young man with a mysterious presence, positioned centrally with comfortable negative space around him. He has a natural oval face, medium tan skin, and medium-sized dark brown almond-shaped eyes with an attentive, neutral gaze. He wears black rectangular acetate glasses with moderately thick frames that leave his moderately thick black eyebrows visible. His thick, straight black hair is styled in a short curtain cut with a near-center part, falling naturally to eye level without covering his eyes. He possesses a slim, healthy build and is dressed in an elegant, matte all-black Japanese kimono with a simple, traditional layered construction. His hands are resting calmly at his sides, just out of frame. The background is a dark nocturnal setting with subtle blue-gray tones and a quiet supernatural atmosphere. The visual style features refined hand-drawn linework, clean cel shading, and atmospheric lighting reminiscent of Vanitas no Carte and Noragami, utilizing a cool blue-gray highlight palette on the black hair for a sophisticated, mysterious mood.
