Hyakuemu.

From the moment he was born, speed was the one gift he possessed. He had no other talents to speak of—only legs that could outrun anyone. That singular ability earned him a place at school and served as his bridge to friendship; running was, quite literally, all he had, and his entire identity rested upon it. Then he crossed paths with a very different kind of runner. This boy was slow, lacking any trace of natural talent, yet he ran with everything he had—not for victory, but to escape, to forget the hardships of his life. Where the first boy possessed speed, the second possessed passion, and that passion burned bright enough to be contagious. Slowly, the naturally gifted runner found himself infected by the same fire. For the first time, running became more than a talent; it became a feeling, an excitement he could no longer ignore. But as exhilarating as this awakening proved to be, it also marked the beginning of something far stranger—an "abnormality" that would alter everything he thought he knew about himself and the sport he once defined.
