This SD figure captures Katsura Kotonoha with a compact, chibi-style silhouette that emphasizes cute proportions while preserving recognizable features. The figure stands with a gentle pose, one hand resting at her side and the other slightly extended, suggesting shy courtesy. Kotonoha's long jet-black hair is sculpted in smooth, flowing strands that fall past her shoulders, with subtle shine lines to convey glossy texture. She wears a crisp school uniform: a white blouse with sailor collar, a navy pleated skirt, and a modest ribbon tied at the chest. The sculpt includes fine details such as the collar trim, pleat texture, buckle on the belt, and small shoes with light sole highlights. The paint job uses soft skin tones and delicate shading on the face to evoke her reserved demeanor. The SD figure is designed with a compact weight balance so it stands upright on display shelves, without requiring a stand.
