From the base, Hatsune Miku stands poised on a stylized stage platform that glimmers with holographic stars. Her long aqua twin-tails cascade with a luminous glow, styled with a smooth gradient from teal to sea-green tips. She wears a futuristic dress that blends sleek black panels with shimmering aqua accents and translucent panels that catch light as if filled with starlight. The outfit is adorned with star motifs and chrome-like trims, giving a sense of motion even while she is still. Her boots are thigh-high, glossy with reflective surfaces and subtle crystalline inlays. The sculpt captures a dynamic pose—one leg stepping forward, arms curved as if conducting a melody. The overall palette radiates cool blues and silvers, with tiny magenta energy accents at the edges to evoke a starry night performance.

Within the Hatsune Miku Project Diva Mega 39's universe, Star Vocalist is a stage persona who travels the night sky aboard a beam of music. Luminasta embodies the idea that light and song are one, drawing constellations by singing; her voice shapes the glow around her. In this tale, Miku uses her luminous outfit to guide driftwood satellites and fans on a mission to brighten a forgotten concert planet. The Mega 39's era celebrates collaboration across songs and stories, and Star Vocalist is the emblem of that unity. On every performance she channels a celestial chorus, the choreography weaving notes into light trails, and the audience becomes a galaxy of appreciative sparkles. This figure captures that narrative energy, frozen at a peak moment when the spotlight meets the night sky.
