Anime Boy Running with Sakuga Animation Style

the prompt

The boy runs, his legs cycling through a full running stride with sakuga precision, every position of the run cycle held clearly and distinctly — not smooth but punchy, the way great anime running feels, each step a drawing rather than an interpolation. Speed trails explode behind him as yellow, blue, orange, and red streak horizontally from his body toward the right edge of the frame, extending further with every stride, building and accumulating into increasingly vivid motion. Dust clouds burst from his back foot with each push off the ground, small explosive puffs that instantly merge into the rushing color trail behind him. His hair whips backward, fists driving forward, mouth open not in a scream but in the effort of pushing through the air — the expression of someone running at the absolute limit and choosing to go even faster. The teal space ahead remains completely empty and still; he runs into nothing, because the running itself is the destination. Flat cel fills hold on his body the entire time — green shirt, teal shorts, gold shoes, warm skin — with no color bleeding into the speed trails. The trails exist as their own element, pure motion made visible, while the teal background remains flat and clean. The camera stays static as he runs across the frame but never leaves it.
