Аниме-школьница с заколкой-молекулой

Polished anime-style half-body portrait of a cheerful schoolgirl on a solid pure black background. She has very long [bright golden blonde] hair with thick layered bangs, loose hair cascading down her back, and a high side ponytail sweeping to the right. Her eyes are large, vivid [emerald green], complemented by an open-mouth smile, subtle cheek blush, and crisp dark linework. Facing forward in a confident, friendly pose: her left hand is raised beside her cheek making a peace sign (V sign), her right hand rests on her hip, and her shoulders are slightly turned. She wears a Japanese school uniform consisting of a fitted royal blue blazer with exactly 5 visible gold hexagonal buttons (2 on the raised left cuff, 1 at the front waist closure, 2 on the right cuff), a white collared shirt, a tan ribbed V-neck sweater vest, a purple necktie with diagonal gold stripes, and the waistband of a green pleated skirt. Above the side ponytail is a distinct red chemical-structure hairpin featuring a thin stem connecting to two hexagonal molecular rings with tiny glowing node dots, alongside the red letters "NH" on the right. Rendered in crisp cel-shaded anime style with smooth tonal gradients, glossy hair and eye highlights, accurate hands, and subtle fabric creases. Centered square framing, isolated subject, no background elements, no watermarks, no extra text except "NH".
