Create a whimsical and charming 9:16 wallpaper in a Niji style, featuring Jiji, the black cat from Ghibli films, in a lush, greenery-filled farm. The scene should be viewed from behind Jiji, showing him gazing out at the vibrant fields filled with tall grass, colorful wildflowers, and a distant farmhouse. The atmosphere should be serene and magical, with soft, natural colors and a bright, clear sky. Jiji's sleek black fur should contrast beautifully with the lively green surroundings, capturing the essence of peaceful countryside life in a dreamy, Niji-inspired style.
