Stands with a confident forward lean, Hatsune Miku in the Piapro Characters Conceptual Series Vol. 2: Luminasta radiates energy through a luminous, sculpture-style design. Her iconic teal twin tails cascade behind her with translucent gradient tips that catch studio light, giving the impression of inner glow. The sculpt captures meticulous details from the pleated skirt to the sculpted sleeves and the buckles along her boots. Color blocks blend sea-green, teal, and silver, while subtle shading adds depth to the musculature and folds. The base presents a crystalline lattice that mirrors a sound-wave motif, enhancing the sense of motion even when stationary. Painted highlights emphasize glass-like surfaces and reflective edges, delivering a striking yet harmonious silhouette worthy of a concert stage.

Within the Piapro Characters universe, Hatsune Miku reappears as Luminasta, a guardian of luminous melodies. In this concept, she taps into the flow of sound as if it were liquid light, sculpting streams that wrap around her like ribbons of aurora. The backstory for Vol. 2 imagines night stages where the crowd's cheers are transformed into glow that travels along the performer’s dress, powering her aura and guiding the choreography. Miku's outfit is redesigned to resemble etched glass and light-drawn circuitry, merging classic Vocaloid identity with a futuristic shimmer. She stands on a crystalline pedestal that hums with imagined resonance, ready to channel the audience's energy into a radiant performance. As the lights rise, the world beyond the stage seems to blur into a dreamlike city of holographic billboards and ever-shifting colors, all built from sound and light.
