Captured in a poised, mid-action stance, Yahagi stands with one foot stepped forward, her navy-tinged uniform neatly tailored to her lithe figure. The renewal edition highlights finer sculpt lines along the collar and cuffs, giving a crisp, metal-like sheen to the buttons. Her hair, styled in gentle waves, frames a calm, focused expression that conveys her duty as an escort ship. Accessories include the ship's emblem on her hat and the subtle hint of anti-submarine gear at her waist, while the base features nautical detailing and rippling water effect. The paintwork uses nuanced shading, crisp color separation, and subtle weathering to evoke a lived-in, maritime atmosphere.
