character: hisakawa_hayate, character: hisakawa_nagi, A medium shot from a slightly low angle depicts hisakawa_hayate and hisakawa_nagi performing on a brightly lit concert stage. Both girls have very long grey hair with braided bangs; Hayate has her hair flowing and blue eyes, while Nagi wears low twintails tied with black ribbons. They are both dressed in matching sleeveless, off-the-shoulder mini-dress performance outfits. Restraining them are polished metal handcuffs on their wrists, shackles on their ankles, and sleek metal collars around their necks. Hayate stands on the left, holding a microphone with a wide, energetic smile, while Nagi stands on the right, tilting her head with a soft, vacant expression, her hands resting loosely at her sides. The background is a grand idol stage featuring flashing spotlights, shimmering confetti, and a distant, cheering crowd. The atmosphere is high-energy and theatrical, with vibrant stage lighting casting colorful glows and sharp highlights on the metallic restraints and glossy fabric of their dresses.橫山育人
