A frontal portrait of a witch in the style of 'Demon Slayer,' her long deep blue hair flowing like a galaxy with stardust shimmering within. Her eyes are heterochromatic—one blue and one gold, like the sun and the moon—with a serene and profound expression. She wears a pointed wide-brimmed witch hat with a star map lining the brim and a miniature planetary ring floating above the peak. She is dressed in a black velvet high-collar robe featuring silver embroidered rotating astrological charts, draped in a translucent gauze cloak that seems to contain a miniature cosmic nebula. Wearing lace gloves, she holds a glowing crystal ball with a galaxy slowly rotating inside, while ancient star map scrolls and a quill float at her feet.
