Hyakuemu.

100 METERS follows Togashi, a track star who is born to run. As a kid, he is naturally gifted and wins every 100-meter race without effort. But in sixth grade, he meets Komiya, a transfer student who is full of determination but lacks technique. In teaching him, Togashi gives Komiya a new purpose: to win no matter what. Years pass by, and Togashi and Komiya meet again as rivals on the track and reveal their true selves.
