⚙️ Recommended Settings

• LoRA Weight: 0.8 - 1.0 (A strength of 1.0 is recommended to ensure all the tiny details like the neck bell and x hair ornament are correctly rendered).
• Base Models: Optimized for Illustrious XL and Pony Diffusion V6 XL.
• Environment: Works best in floating islands, blue sky, cozy gaming room, virtual stage, cherry blossom park, futuristic city.
• Pro-Tip: Kokoro’s fang is a crucial part of her charm—ensure the prompt includes fang or open mouth. To capture her "dragon" lore, try adding dragon, riding dragon, or cloudy sky to the background. Her blue hair is very light, so light blue hair often yields more accurate results than just blue hair.
