Seasonal Path Transition Animation

[Protagonist] A 2nd-grade elementary school girl with a black bob. [Setting] A shrine approach lined with torii gates. [Video Style] 15 seconds. Japanese full-color anime. High-density 2D animation with a 500 million yen budget scale. Meticulous background art, smooth in-betweens, and movie-quality cinematography. Develop attractively by changing compositions, camera angles, screen sizes, and character distances so that similar images do not repeat. No subtitles, no watermarks, no BGM. Includes environmental sounds. [Video Structure] The path the protagonist runs on changes seasons with every step. She maintains her speed by changing her form each time, and for an 'empty' step in the middle, she steps ahead in the air to cross it. Only the final step returns to a normal road. Shot 1 (Transition Hook): A shrine approach with torii gates. Every time the protagonist takes a step, the season switches entirely. An expression of surprise and curiosity. Shot 2 (Continuous): Second and third steps. Seasons change with each step, with scenery and sounds following suit. The protagonist's eyes busily follow the surroundings. Shot 3 (Adaptation): The protagonist maintains speed while changing form. At the transition seams, hair sways in two different types of wind. A calm expression of adaptation. Shot 4 (Close-up): Close-up of feet. A boundary between two worlds runs within a single step. A gaze focused on judging the footing. Shot 5 (Empty Step): Nothing at the position of the next step. The protagonist steps ahead in the air first, summoning a floor of light. Tension from the split-second decision. Shot 6 (Rush): Running full speed for the last ten steps. Seasons switch at high speed, and footsteps become a percussion rhythm. Running through with an elated expression. Shot 7 (Normal): The final step is a normal road. The protagonist says 'I went through four seasons in three seconds' with a let-down face.
