"Stride"—an extreme sport that combines parkour, free running, relay, and sprinting—is what made first year high school student Nana Sakurai enroll in Honan Academy, after being captivated by the school's stride team. Sharing the mutual intention of joining the team is fellow first year and stride maniac, Takeru Fujiwara, and together they request to join. Much to their dismay, however, the stride club is no longer active due to lack of members, and they are now operating under the shogi club.

In order to revive the stride club, Nana and Takeru recruit first year Riku Yagami—a fast runner who is interested in almost every sport. With this new team, the club now aims high at a new goal: to win the prestigious End of Summer competition, and bring the Honan stride team back to their prime.
