Shiteyan'yo is captured in a dramatic, action-oriented pose that reads as both elegant and energetic. The figure features a flowing, tailored jacket with layered cuffs and a crisp white top beneath, all sculpted with fine relief to mimic fabric folds. Her hair cascades in long, glossy twin-tails, dyed from midnight blue at the roots to bright cyan at the tips, with each strand meticulously separated to catch the light. Small accessories include a microphone and a stylized belt buckle, while the base evokes a concert moment with musical notes and a soft teal halo that seems to glow under display lights. The painterly finish emphasizes crisp edge lines, subtle shading in the recesses, and a high-gloss finish on facial features and hair, giving Shiteyan'yo a vivid, collectible presence.

Shiteyan'yo's backstory places her as a nocturnal muse who awakens when a city falls quiet after a long rehearsal. Born from a collaboration between Cherry Boy's and the Vocaloid legend, she travels between stages and studio stairwells, gathering forgotten melodies and weaving them into new choruses. Her voice is described as crystalline and airy, with a moonlit undertone that can comfort an anxious vocalist or ignite a late-night jam. In her lore, she carries a crest of stars and sound waves, symbols of guidance and inspiration, inviting fans to chase their own musical ideas. Each tale expands across releases, growing her mythos as collectors discover new facets of her personality through her figurine.
