Kurahara Kakeru runs through the city streets at night. A single man chases after him on a bicycle. That man’s name is Kiyose Haiji. When Haiji catches up to Kakeru, he asks him a question: "Hey, do you like running?" Led by Haiji, Kakeru arrives at the Chikusei-so student dorm. He meets the strange residents living there. Haiji behaves in a peremptory manner. Kakeru is bewildered by the sudden development. No one at the dorm is aware of Haiji’s ulterior motive. That night, the residents hold a welcoming party for Kakeru. At the party, from Haiji’s mouth comes a grand and reckless plan. How will Kakeru respond…?

"The residents of the Chikusei-so will run in the Hakone Ekiden together." Kakeru responds strongly to Haiji’s rash suggestion. All the residents are amateurs when it comes to long distance running. Nobody takes Haiji’s words seriously. The residents attempt to carry on with their college lives, but Haiji’s shadow approaches. Threatened by Haiji’s mysterious pressure, several tragically fall to Haiji’s hand. Kakeru tries to leave the Chikusei-so, but he runs into Nico-chan in the city. Meanwhile, the Chikusei-so’s bath breaks for unknown reasons, and they decide to go to the "hellish" public bath instead…

"It’s been a while…" Sakaki smirks fearlessly. He and Kakeru are old acquaintances. Kakeru is unable to hide how shaken he is by their unexpected reunion. Swirling inside Kakeru was the loneliness he experienced as a high school student due to his talents. Kakeru runs as though fleeing from shadows, when before him appears "the other Kakeru." It is the desperate man he used to be before he met Haiji. Kakeru glares resentfully at his past. Just as he’s about to lose hope in himself, someone with a kind voice reaches out to him. It’s Prince and his friends…

The residents of the Chikusei-so go to Tokyo Sport University in order to attend their first track meet. While there, Kakeru is reunited with his old teammate Sakaki Kosuke. Sakaki persistently attempts to provoke Kakeru. When Haiji tries to stop them, a man calls out to him. That man is the champion of Hakone and Rikudo University’s ace, Fujioka Kazuma.

Kansei University’s battle to achieve official records formally begins. Having already achieved their official records, Musa, Jota, and Joji watch the race with Hanako. Kakeru joins the lead pack and competes with exchange students from strong schools. Meanwhile, the stagnating Shindo and Yuki utilize their strengths to make a strong effort towards achieving an official time. During the final lap, Haiji’s words cut through Kakeru’s mind. "Do you like running?" In that moment, something inside him opens, and Kakeru bangs out an astonishing time. After the race, a lone reporter approaches Kakeru, and…

The entire team achieves offical records. Having earned the right to compete in the qualifier, Haiji reports their progress to Coach Tazaki. Though they still have many challenges to face before they make it through the qualifier, the expections of everyone around them continue to rise. They even receive an interview request from a TV station. While the others are excited, Yuki alone seems unhappy.

A runner from another school trips and falls right in front of Haiji. Fortunately, he’s able to avoid crashing into him, but he puts all his weight on his right leg. The fall causes a commotion at the water station. The cold rain mercilessly pounds down on the runners and the fans watching over them. Eventually the races moves into the city streets, and the runners’ race for survival accelerates.

While walking home with Musa, Kakeru runs into reigning champion Rikudo’s Fujioka Kazuma. When Kakeru can’t let go of the inconsiderate remarks made by some passers-by, Fujioka methodically and without faltering shows him the answer. Then Fujioka tells them about his shared history with Haiji. The burden Haiji has borne alone. The response he gave to Fujioka. In Fujioka’s words, Kakeru begins to sense the meaning of the "strength" Haiji once described to him. Meanwhile, Haiji is at a consultation with his doctor. His eyes are glued to the harsh reality they see…

The Tokyo-Hakone Round-Trip College Ekiden Race finally begins. Haiji was right, and Section 1 moves at a slow pace while the teams try to feel each other out. Prince, who bears the heavy responsibility of starting the race, takes up his position behind the other runners and conserves his strength. It’s all part of Haiji’s plan to take the top. Haiji also sends a message to Prince through Tazaki in the coach’s vehicle and heads to the Tsurumi Relay Station where Musa waits. The group raises its pace. Prince desperately hangs on. And in the back of his mind, he recalls a conversation he once had with Haiji…

His teammates faced death to pass the sash along. Bearing that weight in his mind, Yuki prepares for the race. Shindo approaches him. Turning his overflowing anxiety and regrets into strength, Yuki waits for the race to start. Meanwhile, in Yokohama, Kakeru and Haiji wait for Sections 9 and 10 to start. However, when Haiji is nowhere to be found, Kakeru grows uneasy. As though confirming his concerns, a sports doctor exits Haiji’s room. Kakeru interrogates Haiji, but Haiji remains the same calm Haiji he’s always been. It’s 8AM. The second half begins!

Kakeru is bewildered by this new experience. His speed overwhelms the other competitors. Meanwhile, reigning champion Rikudo’s ace Fujioka breaks the section record as promised and pushes his team into first place. Fujioka finds Haiji. What answers wait for them at the ends of their roads? They reassure one another as they exchange words. Prince’s smile pushes Haiji’s quiet resolve forward. Kakeru eventually appears at the relay station, running at shocking speeds. Their dream lies before them. Kakeru passes to Haiji. Their sash unites them and their entire team. At what peak will the Kansei University track and field team arrive?
