Edit the anime group illustration: modify character #8 (the blonde girl positioned in the center, directly behind/above Kazuma, between Kazuma and character #2) to perfectly match Felix Argyle (Ferris) from the reference image. Replace character #8 with Felix Argyle: light brown/tan hair with fluffy cat ears on top, white ribbons with blue accents tied into the hair, large expressive amber/golden cat-like eyes, blushing cheeks, cute cat-mouth expression (w-shaped smile), wearing the distinctive blue and white frilly dress with collar ribbon and blue choker with a bell. Felix should be in the exact position of #8, leaning over Kazuma with a playful, cute expression. CRITICAL: Keep all other characters completely unchanged (Kazuma, Emilia, Ram, Rem, Darkness, Megumin, and the other girls remain in their exact same appearances, expressions, and positions). Retain the anime art style, vibrant colors, line work, and overall scene composition intact.
