Eri Mouri, a young woman with long, wavy dark-brown hair and gentle brown eyes, is shown in a medium close-up portrait against a soft, neutral gray studio background. She wears a simple white blouse with a delicate lace collar and a thin gold necklace, her head slightly tilted with a calm, approachable smile. Soft, diffused studio lighting gently illuminates her face from the front-left, creating a subtle highlight on her cheekbones and a smooth gradient across her skin. The overall mood is serene and elegant, with a muted color palette and delicate, fine-textured rendering.
