Seedance 2.0, 15 seconds, 16:9, high-quality anime movie style. A high school girl in a classroom instantly dissolves into light particles and completely vanishes, then reconstructs into a singer costume from particles on a live stage in the next moment. A flashy, high-speed teleportation transformation that keeps the audience captivated.
Role of Reference Images:

Image 1: Protagonist and school uniform before transformation
Image 2: Singer costume and microphone after transformation
Image 3: School classroom before vanishing
Image 4: Live stage after appearing
Image 1 and Image 2 are three-view drawings (front, side, back) of the same female character, not three different people. Use the central front view as the base, and use the side/back views only as references for costume structure. Perfectly maintain the protagonist's face, purple-blue eyes, dark navy hair longer than the waist, hairstyle, and physique throughout the transformation. There should always be only one character.

Before transformation: navy blazer, white shirt, chest ribbon, checkered pleated skirt, navy high socks, brown loafers from Image 1. After transformation: accurately reproduce the silver-white bodice, blue crystal decorations, blue glowing navy pleated skirt, iridescent transparent sleeves and long costume tail, large back ribbon, black-navy long boots, blue hair ornament, and blue-black microphone from Image 2.

0.0-2.2s: An empty classroom with sunset light (Image 3). White curtains sway heavily in the wind, and the protagonist stands alone in the central aisle between desks in uniform. Rapid dolly-in to the protagonist from a wide angle. She senses something and looks up. Classroom ambient sound, wind, distant chimes.

2.2-3.5s: A blue-purple circular teleportation array instantly ignites at her feet. Thin light beams erupt from the floor, running through the uniform buttons, chest ribbon, and skirt patterns at high speed. Surrounding dust and light particles are sucked toward her, and her long hair and curtains flap violently toward the center in a powerful suction wind. Energy sounds rise sharply.

3.5-4.2s: The uniform and protagonist's silhouette dissolve from the outside in into countless dark navy, silver, and blue-purple light particles. Particles do not spread but compress ultra-fast toward a single point at the chest. The fabric, hair outline, and silhouette are sucked into a light point within 0.7s; she completely vanishes. Maintain face and hair until just before disappearance, with the body covered in opaque light.

4.2-4.6s: The compressed point emits a sharp blue-white flash and generates a reverse circular shockwave before disappearing. Papers on desks, curtains, and dust are blown violently by the shockwave. She is completely gone, leaving only the classroom. An afterimage floats momentarily as a thin ring in the air.

4.6-4.9s: Show the empty classroom clearly for about 0.3s. Complete silence. Do not gradually transform the background into a stage. Do not mix classroom and stage. No early display of portals or the stage.

[hard cut / instantaneous teleport] 4.9-5.2s: Live stage center (Image 4). A tiny blue-white light point suddenly appears at the same screen coordinates where she vanished in the classroom. The stage blacks out for a moment, and all lasers focus on the light point.

5.2-6.2s: The light point explodes into a massive spherical energy burst, radiating silver-blue particles, crystal fragments, and light feathers in all directions at high speed. The protagonist's silhouette is drawn in particles at the center. The light silhouette reconstructs in order: feet, legs, torso, arms, long hair. Use the same color, trajectory, and rotation as the classroom particles to clarify it's the same person teleported.

6.2-8.5s: Particles flow back into the reconstructed silhouette. Form the black-navy long boots, blue glowing pleated skirt, silver-white bodice, and blue crystal chest/shoulder decorations from Image 2 at high speed. Next, the iridescent sleeves and tail expand like a light film, and the large back ribbon unfolds like a flower. Do not show the uniform; build it already converted into the singer outfit during teleportation.

8.5-9.8s: Final light particles gather at the side of her hair, fixing as a blue crystal ornament. Remaining particles flow into the right hand, generating the blue-black microphone from Image 2 from a slender glowing outline. The moment she grips it, the costume borders and crystals flash at maximum intensity.

9.8-10.5s: Transformation complete. She lands powerfully on the stage floor. A massive blue-purple light pillar, double circular shockwaves, crystal shards, star particles, and light wings explode outward upon landing. Camera shakes briefly from the impact then rapidly approaches her. Synchronize the heavy bass impact and crystal sounds.

10.5-12.5s: Camera orbits her at high speed for 180 degrees. The long navy hair, transparent sleeves, tail, and back ribbon flutter heavily from centrifugal force. She steps out onto the runway and raises the microphone high. Abstract blue-purple acoustic waves run across large screens.

12.5-15.0s: The entire stage from Image 4 lights up explosively. Countless blue-purple lasers cross, audience penlights wave in unison, and light pillars and star particles erupt from the floor. The camera pulls back rapidly from a low floor-level position to an ultra-wide shot, showing her full body standing at the center of the massive stage. Finally, she looks at the front, raising the microphone, and giant silver-blue light wings open behind her. End by showing the completed costume and face clearly.

Important Constraints:
Do not gradually change the background. Do not overlap classroom and stage. Do not show the stage through a portal in the classroom. Strictly follow: "Complete disappearance in classroom -> instantaneous gap -> sudden appearance on stage." Always one character. Do not generate the three-view as three people. No duplicates, afterimages of different people, facial changes, hair shortening, instant costume swapping without particle effects, mixed uniforms, extra limbs, mic duplicates, text, subtitles, logos, or watermarks.
Audio:
Shift from quiet classroom ambience to a rapid energy rise and compression sound. A sharp "shun" and absolute momentary silence during vanishing. Simultaneous start of heavy bass, crystal particle sounds, audience cheering, and high-tempo electronic music upon appearing. No dialogue or singing.
