"Create an illustration of Giyū Tomioka from Demon Slayer standing in a side view. His calm, composed expression contrasts with the powerful background, which merges elements of water and nature. Flowing waves surround him, intertwining with lush trees and leaves, all rendered in various shades of blue. The scene should feel serene yet strong, emphasizing his water-breathing techniques. The style should be bold and detailed, reflecting the elegance of Japanese animation with a soft, ethereal touch." --ar 16:9
