character: ruby_(oshi_no_ko), A medium shot, eye-level anime illustration of Ruby Hoshino from Oshi no Ko, centered in the frame against a softly blurred stage background. She is a teenage girl with long, flowing blonde hair and distinctive sparkling star-shaped pupils in her bright eyes, wearing a vibrant, ruffled idol stage costume adorned with ribbons and sequins. She is posing dynamically with one hand forming a "V" sign near her cheek and the other resting on her hip, sporting a radiant and energetic smile. The background consists of a concert stage with shimmering spotlights and floating glitter particles, creating a sense of depth. The visual style is characterized by high-quality cel-shading, a bright and saturated color palette dominated by pinks and yellows, and a glamorous, idol-like atmosphere with luminous lighting effects.
