Ziyu Pan commands attention as the older twin in the idol-racer duo Hell's Kitchen, her jet-black hair swept into high pigtails secured by yellow ribbons with face-framing strands accenting golden-yellow eyes. Casual outfits combine a bright pink schoolgirl top with white sleeves and dark collar, paired with thigh-high white stockings, red heels, and a purple rabbit brooch. Her performance-racing hybrid costume features a white-and-gold Mandarin-style dress with a heart-shaped neckline, blue-red bows, thigh-high boots, and lilac rabbit ear accessories.
