Against the backdrop of a medieval city square at dusk, a 12-year-old girl stands tall, her porcelain skin aglow under warm street lamps. Her striking heterochromatic eyes - shimmering blue and fiery red hues - seem to gleam like precious jewels in the soft light. Long silver hair styled in an elegant updo cascades down her back like a river of moonlight. She wears a sailor-style uniform with intricate details, juxtaposed against the mystical ambiance created by light gothic armor adorning the background.
