Pastel-colored anime illustration of Zena, the top idol heroine (1.3), performing on a bright outdoor stage (1.2). She wears a pastel-orange and pastel-pink off-shoulder mini-dress (1.3) with frills and translucent layers (1.2), glowing under the radiant stage lights. Her short pastel-orange bob hair (1.3) sways with her dance, accented by her iconic pastel-pink headphones (1.2). Captured from a professional photographer’s low wide-angle shot (1.2), Zena shines at the center of the composition, fans waving pastel glow sticks (1.2) in the background. Her pose is playful, mid-dance with a lively twirl (1.3), one hand reaching toward the audience. Her face beams with a brilliant idol smile (1.4), yet in her eyes there is a subtle mischievous glint (1.2), as if teasing the crowd with a secret. She radiates irresistible cuteness, but beneath it lingers a faint, almost invisible aura of temptation (1.2). That aura takes form as transparent devilish effects (1.2) — faint heart-shaped ripples, soft smoky swirls, and shimmering outlines of tiny horns and a tail (1.1), only barely perceptible in the glow. They don’t distract from her idol radiance but add a hidden layer of small-devil allure (1.2), making her smile feel like a spell of playful seduction. The atmosphere balances idol brightness (1.3) with a delicate, unseen coquettish demonic charm (1.2), as if Zena’s fan service is both genuine love and a mischievous enchantment that only her fans can feel in their hearts.
