As far back as anyone can recall, Togashi has been the quickest elementary school student in the area. His speed renders him unbeatable in every gym class and sports day event, with his talent most evident in the hundred-meter dash. Tired of the lack of rivals, he chooses to assist Komiya, a transfer student who enjoys running but consistently finishes last due to poor form. For a brief period, the pair are inseparable, bonded by their shared pursuit of speed. However, this ends when Komiya departs as abruptly as he had arrived. Years go by, and both boys continue to refine their abilities. Although their paths and challenges vary, they each strive to push their limits, seeking to determine if Togashi's longstanding conviction—that every problem can be resolved by being the fastest runner in the hundred-meter dash—holds true.
