A medium shot, front-on angle anime illustration features five idol girls posing symmetrically on a 3D virtual concert stage, with Isaki Riona centered as the leader. From left to right: Kikirara Vivi in a black croptop jacket, beige wide-leg ripped pants, and sunglasses on her head; Koganei Niko in a black tube top and dark purple baggy sweatpants; Isaki Riona in an asymmetrical red and black short jacket and contrasting black-and-white tight pants, raising one arm powerfully; Mizumiya Su in an oversized white puffer jacket with wave patterns on the sleeves; and Rindo Chihaya in a black punk-rock mini skirt with crisscross thigh straps. All hold wireless microphones, wearing chunky laced boots and accessories like chain necklaces or large headphones around their necks. They stand atop a large, glowing deep pink rose emblem on the stage floor. The background is a high-tech virtual space filled with dense, intersecting neon blue laser beams, with "Orchestra" (オーケストラ) and birthday hashtags displayed in holographic text above. The atmosphere is electric and celebratory, featuring vibrant neon colors, sharp digital lighting, and a high-energy live-stream aesthetic.
