Mysterious Ninja Girl Design with Enigmatic Aesthetic Elements

Design a young girl with a mysterious, ninja-inspired aesthetic. She has long purple hair, slightly messy or tied in a braid, and wears a dark, hooded cloak that flows slightly with motion. Her outfit combines traditional shinobi elements with a modern twist—layered tunics, arm guards, utility belts, and lightweight boots. Her eyes glow faintly (silver or violet), hinting at hidden power or a magical heritage. She carries a small dagger or charm tucked into her belt. Her expression is calm but alert, a survivor’s look. The overall color scheme should include dark purples, blacks, and soft metallic accents. The setting can suggest a post-clan or mystical ruin background.
