Pastel-colored anime illustration of Zena, the top idol heroine (1.3), on an outdoor concert stage illuminated by soft moonlight (1.3) and pastel spotlights (1.2). She wears a pastel-orange and pastel-pink off-shoulder mini-dress (1.3) with delicate frills and translucent layers (1.2), glowing with idol radiance. Her short pastel-orange bob hair (1.3) bounces with her dance, accented by her signature orange headphones with cute monkey ears (1.4). Captured from a professional photographer’s wide-angle stage shot (1.3), slightly low to enhance her presence, Zena dances gracefully, her hand reaching toward the audience (1.3). Fans wave pastel glow sticks (1.2), their cheers rising into the night sky. Her expression is a full radiant idol smile (1.4), but in her eyes flickers a mischievous, teasing sparkle (1.2) hinting at something hidden. She radiates pure idol cuteness, yet there is an invisible undertone — a faint demonic aura (1.1), intangible and imperceptible to the fans around her. That aura is not literal, but woven into the atmosphere: transparent ripples of shadow and faint smoky glimmers (1.1) that blend with the stage’s moonlit glow (1.3). They are unseen by the cheering crowd (1.3), existing only as a subtle illusion in the air, adding depth to her presence. The overall scene balances idol brightness (1.3), playful monkey-ear charm (1.4), and a hidden small-devil aura (1.1) beneath the pastel stage lights and silver moonlight, making Zena appear both as a pure shining idol and a mysterious, untouchable enchantress.
