The K-ON! Akiyama Mio figure presents a poised and eye-catching display piece. Mio stands with a confident but gentle stance, her left hand resting on the neck of a carefully sculpted bass guitar, while the right hand is positioned near the strings. Her long, straight hair flows naturally, with a subtle sheen and a ribbon or hair accessory gently pinned to one side. The sculpt captures Mio's delicate features, soft eyes, a serene smile, and a school uniform rendered with attention to layered fabric folds and precise pleats. Color palette blends deep indigo hair, a school blazer, light blouse, and a crisp skirt, accented by metallic guitar hardware and strap that catch light. The base is unobtrusive, designed to support a dynamic pose without overpowering the figure.
