A full-body character design of a female knight clad in "Black-and-Gold" ornate plate armor, in Takayoshi Kuroda’s decorative and polished style. The armor is covered in intricate, hand-etched engravings and delicate filigree patterns, reflecting the surrounding light with a brilliant metallic sheen. The character holds a translucent crystalline sword that glows with an inner light. The art style is highly polished and decorative, emphasizing the "cool and beautiful" (cool-beauty) archetype with a slender but strong silhouette. The background is a simple but elegant cathedral interior with stained glass windows. The coloring is rich, high-contrast, and luxurious. The mood is "regal, powerful, and impeccably detailed."
