Anime-style illustration of Eirin Yagokoro, a beautiful and calm moon sage and genius pharmacist with long silver hair styled into a single braid, and straight center-parted bangs. She has serene, intelligent blue eyes and a composed expression with a faint, knowing smile, giving an impression of immense wisdom and gentle authority rather than coldness. She wears a uniquely designed outfit inspired by both Chinese-style clothing and medical/nurse motifs. The outfit features a two-tone color scheme of deep blue and red, split asymmetrically: the upper garment has the right side red and left side blue, while the skirt reverses this color arrangement. The sleeves are short with delicate frills, and the overall silhouette blends traditional Chinese clothing aesthetics with a refined, ceremonial medical theme. She wears a distinctive two-tone nurse cap (dark blue base with a red cross emblem on the front center), symbolizing her role as a pharmacist and medical expert. The red cross is stylized and integrated into the design, not associated with real-world organizations. Her outfit is decorated with subtle constellation patterns: Vega (Lyra) on the hat, Cassiopeia and the Big Dipper on the upper garment, Sagittarius-related star patterns on one side of the skirt, and Andromeda-related constellations on the other. The hem of the skirt features an Eight Trigrams (Bagua) pattern, adding an esoteric and mystical element. She wears simple white socks (childlike ankle-length stockings), consistent with her original appearance. She stands or calmly performs medical or alchemical work in a quiet, moonlit, traditional-style medical chamber filled with scrolls, herbal tools, and softly glowing medicinal objects. The atmosphere is serene, mystical, and highly intellectual, emphasizing
