A hyper-realistic, full-body 3D rendering of Rimuru Tempest in human form, with an emphasis on photorealism. Rimuru has soft, slightly messy silver-blue hair that reflects light naturally, and deep, lifelike blue eyes that are strikingly realistic, showing subtle emotions and depth. The skin is flawlessly smooth, with a natural human texture, including slight imperfections like faint freckles or pores to enhance realism. Rimuru is wearing a dark, fitted outfit made of leather and fabric, with silver accents and intricate details that catch the light. The outfit is a blend of modern and fantasy design, appearing practical yet elegant. The setting is a beautiful, moonlit beach, with the character captured mid-jump, arms gracefully extended, and hair flowing dynamically. Above, the night sky is dominated by a breathtaking, photorealistic Milky Way, with stars and galaxies rendered in high detail, casting a soft glow on the scene. The sand beneath Rimuru's feet is wet and textured, with realistic footprints and subtle reflections from the starry sky. The waves gently lap at the shore, adding movement and realism to the scene. Every detail, from the fabric's texture to the reflection in Rimuru's eyes, is designed to enhance the lifelike quality of the character and the environment.
