Torn Dress Warrior Unleashes Rainbow Cannon Against a Planet-Sized Beast

A gentle-looking magical girl in a torn pastel dress stands alone in a ruined amusement park while a planet-sized nightmare creature emerges from a broken Ferris wheel, she transforms mid-sprint, her ribbons becoming blades, her umbrella becoming a cannon and her smile disappearing as she launches through swarms of porcelain monsters, spins between collapsing rides and fires a rainbow beam that bends across the sky but is swallowed by the creature, abandoned theme park at sunset with broken mascots, flooded pathways, floating balloons and distorted carnival lights, beautiful yet terrifying magical-girl anime, graceful sakuga transitioning into brutal combat, elegant spinning camera moves, sudden horror close-ups, painterly backgrounds, highly detailed cel shading, pastel lighting contrasted with deep black shadows and crimson corruption, melancholic dreamlike atmosphere, ending with the heroine snapping her wand in half and releasing a silent white flash that transforms the nightmare into a new constellation above the park.
