For as long as anyone can remember, Togashi has been the fastest elementary school student around. His speed makes him untouchable during every gym class and sports day, and there is nowhere his skill shines brighter than the hundred-meter dash. Bored by the lack of competition, he decides to help train Komiya, a transfer student who loves to run, but whose bad form leaves him consistently in last place. For a short time, the two are inseparable, united by their pursuit of speed. That is, until Komiya moves away just as suddenly as he came.

Years pass, and both boys continue to hone their skills. While their paths and obstacles differ, they each strive to push themselves to the limit, and find out whether Togashi's long-held belief—that all problems can be solved by being the fastest runner in the hundred-meter dash—is true.
