[Video Style]
15 seconds. Japanese full-color anime. High-density 2D animation with a 500 million yen budget feel. Fast cuts, floor-level low angles, macro close-ups, rapid horizontal tracking, ending with a fixed medium shot. No subtitles, no watermarks, no BGM. Sounds of subtle floor friction, breathing, and short ambient noises.

[Visual Composition]
The [Main Character] does not run. They dissolve into the [Anomaly Gimmick], travel along the walls and floors of the [Setting], and re-form at the destination ahead of the [Opponent/Target].

[Shot 1: Dissolve Start]
The [Main Character] is stationary at the back of the [Setting]. Only the feet transform into the [Anomaly Gimmick] and start flowing onto the floor.

[Shot 2: Close-up]
The [Anomaly Gimmick] travels through floor scratches, tile joints, raindrops, and gaps in tatami mats. Macro lens close-up.

[Shot 3: Target's Flight]
The [Opponent/Target] flees toward the camera. The camera pans horizontally in parallel, while the [Anomaly Gimmick] chases from the corners of the background.

[Shot 4: Wall Movement]
The [Anomaly Gimmick] climbs the wall, moving around fluorescent lights and window frames. Shown with gravity-defying movement.

[Shot 5: Splitting]
The [Anomaly Gimmick] splits into multiple thin streams, blocking the [Opponent/Target]'s path in advance. Bird's-eye view shot showing the route.

[Shot 6: Re-formation]
Just before the [Opponent/Target] stops, the [Anomaly Gimmick] gathers in the darkness behind them, forming the outline of the [Main Character].

[Shot 7: Completion]
The [Main Character] completely returns to their original form. Hair and clothing take shape with a slight delay. The camera slowly pushes in.

[Shot 8: Dialogue]
The [Main Character] stands right behind the [Opponent/Target] and says in a calm voice, "I was already here." The final frame ends without showing the target's reaction.
