Pastel-colored anime illustration of Zena, the top idol heroine (1.3), performing on a grand outdoor stage (1.2). She wears a pastel-orange and pastel-pink off-shoulder mini-dress (1.3) with frills, ribbons, and shimmering translucent layers (1.2). Her short pastel-orange bob hair (1.3) bounces with her dance, framed by her signature pastel-pink headphones (1.2). The scene is shot from a professional photographer’s low wide-angle lens (1.2), emphasizing Zena as the radiant center. Fans with pastel-colored glow sticks (1.2) cheer wildly, confetti and sparkles (1.2) floating in the bright pastel air. Her pose is dynamic, one hand reaching out to her fans, her skirt fluttering mid-motion (1.3). Her face shines with a brilliant, idol-perfect full smile (1.4), the kind that melts every heart. Yet, behind her glittering eyes, faintly flickers an ominous, devilish shadow (1.2). In the subtle curve of her lips and the glint in her gaze lies a hint of something darker — an idol angel masking a hidden demon (1.3). Delicate pastel-pink and orange lights bathe her, but at the edges of the stage, faint dark crimson glows (1.2) and whispering black feathers (1.1) drift like a secret veil, symbols of the inner devil she hides. This duality — idol radiance (1.3) versus concealed demonic allure (1.2) — creates a captivating tension, as if her fan service smile itself might be a spell binding every heart.
