Stride—an extreme discipline that blends parkour, free running, relay and sprinting—captured first‑year student Nana Sakurai"s imagination and led her to enroll at Honan Academy after she spotted the school"s stride squad in action. Her fellow first‑year, stride enthusiast Takeru Fujiwara, shares her ambition; together they submit a petition to join. Unfortunately, the stride club has been inactive for years because of dwindling membership and now operates under the shogi society.
Riku, known for his lightning speed on the track, is eager to test his limits in new environments. To revive the club, Nana and Takeru recruit first‑year Riku Yagami—a swift runner with a passion for almost every sport. With this fresh lineup, the club sets its sights on a new objective: to clinch the coveted End‑of‑Summer tournament and restore Honan"s stride team to its former glory.
