重音特（Kasane Teto）流行偶像肖像

Create a vibrant anime close-up portrait of {argument name="character name" default="Kasane Teto"}, a mischievous young virtual singer with vivid {argument name="hair color" default="hot pink"} hair styled into two large glossy drill-twin-tails on both sides, short layered bangs, and loose side strands. She has large pink-red eyes with golden highlights, long black lashes, faint blush, and a playful toothy grin. Pose her leaning toward the viewer in strong perspective, one arm thrust forward with her index finger pointing directly at the camera, the other hand touching her cheek with pink manicured nails. Dress her in a dark navy sleeveless collared shirt with bright magenta piping, magenta buttons, a front placket, and a small chest pocket, with a detached dark navy sleeve visible on one arm. Use a cute pop-idol anime illustration style with clean ink lines, glossy cel shading, soft skin tones, and a thick white sticker-like outline around the character. Set the background to a flat pastel {argument name="background color" default="pink"} with decorative white doodles: exactly 3 outlined stars, 7 four-point sparkles, and 3 short radiating accent lines near the upper right. Make the composition energetic, centered, cropped from the torso upward, with the pointing hand exaggerated large in the foreground and the face framed by the twin drills.
