I want a manga-style anime girl but colored with darker tones in a more gothic style in a Renaissance cathedral in a storm with evil cosmic spirits following her as servants. She must have black hair and a large, long mystical sword with some magical artifacts on her body, marks of years of combat experience on her body, hair as black as night and a cold look like someone who has seen hell with her own eyes, someone who has gone through experiences that have made her cold and expressionless with empty eyes as long as she can in an elegant way showing the lineage and noble blood that runs through her veins. One of her eyes is also different with magical marks made to seal the infinite power that she stores in her. She also has an evil aura around her that terrifies everyone.
