At Kansei University, quiet and practical student Kakeru Kurahara is caught shoplifting food, leading to a fateful encounter with Haiji Kiyose, a senior student and running enthusiast. Haiji immediately recognizes Kakeru’s raw, natural athletic talent and invites him to live in Chikusei-sou, a dilapidated student dorm he manages. Upon arrival, Kakeru discovers the catch: the dorm houses a eccentric group of nine college students who are complete novices to long-distance running. Haiji’s ultimate dream is to lead this dysfunctional team to qualify for and compete in the prestigious and grueling Hakone Ekiden, one of Japan’s most famous university relay races.Initially, the residents resist. The group includes Nico-chan, a heavy smoker; Joji twins, mischievous pranksters; Musa, a gentle
international student; King, an obsessive trivia buff; Prince, a reclusive manga addict; Yuki, a cynical law student; and Kakusei, a former high school runner harboring deep-seated psychological trauma. Kakeru, haunted by his own abusive past in high school track and field that caused him to lash out and quit, is equally hostile. However, through Haiji’s unwavering optimism, culinary persuasion, and gentle yet firm guidance, the reluctant housemates slowly transform. They realize that running is not just about physical endurance, but about self-discovery, confronting personal demons, and trusting the people beside them.As the months progress, the boys endure brutal early-morning training sessions, grueling physical conditioning, and numerous setbacks. They overcome internal conflicts, ego clashes, and the looming threat of academic failure. Kakeru struggles with his perfectionism and tendency to alienate others, but as he bonds with his teammates, he learns the true meaning of teamwork over individual glory. Prince battles agonizing self-doubt to build the minimal stamina required, while Yuki discovers a genuine passion that transcends his cynical worldview.By the New Year,
against all odds and societal expectations, the Chikusei-sou tenants officially qualify for the Hakone Ekiden. On the day of the race, the ten runners pass the sacred sasa-tasuki sash from one to another across the treacherous mountain and coastal courses. Each runner pushes their physical and mental limits to the absolute brink, fueled by the collective spirit of the team. In the dramatic final leg, Kakeru surges forward, achieving a breathtaking athletic breakthrough. Although they do not win overall, they cross the finish line with immense pride, forever transformed by their shared journey.
