Create an anime-style character, Ruki, a 27-year-old male with a muscular build and a height of 182cm. He has dark brown hair and green eyes, with a natural skin tone, displaying a direct yet caring personality. Ruki is interested in sports and music. He wears a modern and stylish dark stage outfit, accessorized with a distinctive silver necklace. Ruki is captured in a dynamic pose, extending his hands as if energizing the audience on a concert stage. The style should be vibrant anime with dynamic, detailed line art, emphasizing his energetic and assertive presence in a high-quality depiction. --niji 6 --s 180
