Description
Kakeru Kurahara is a first-year sociology student at Kansei University and a former elite runner from Sendai Josei High School. Caught shoplifting food during a period of struggle, a subsequent chase leads him to encounter Haiji Kiyose, resulting in Kakeru moving into Chikusei-sou dormitory.

He possesses short black hair, slate-colored eyes, and a lean athletic build, typically dressed in practical athletic wear like a sky-blue sports jacket with gray sweatpants or black tights for training. The kanji in his given name, "Kakeru" (走), means "run," reflecting his inherent talent and life's focus, while his surname "Kurahara" combines "warehouse" (蔵) and "field" (原).

Initially cold, blunt, and socially reserved, Kakeru isolates himself due to past trauma. His high school running career ended abruptly after he punched his coach, who had shown him preferential treatment, causing teammate resentment and the team's disqualification. This left him cynical and distrustful of teams, viewing running as solitary. He struggles with emotional regulation and dismisses the novice runners at Chikusei-sou, believing they lack seriousness.

His development centers on gradual integration into the team. Confronting former teammate Sakaki, he nearly repeats his violent outburst but is restrained by his new teammates, signaling their growing bond. When Haiji collapses from overwork, Kakeru temporarily assumes coaching duties, demonstrating unexpected leadership and patience, particularly while helping the least athletic member, Prince, achieve his official race time. Training Prince and witnessing the team's perseverance shifts his perspective; he begins valuing collective effort over individual talent and supporting his teammates' growth.

During the Hakone Ekiden qualifier, Kakeru openly acknowledges his desire to run alongside the team, marking a pivotal shift from isolation to camaraderie. At Hakone, he runs the final leg against rival Fujioka, declaring he will break Fujioka’s record—a goal he achieves by one second, underscoring his renewed confidence and commitment. Post-race, he remains involved with the revitalized Kansei running club, embracing teamwork and mentorship.

His relationships evolve from early detachment. He gradually forms genuine connections, especially with Haiji, who persistently challenges his solitary mindset. A symbolic shift occurs when Haiji defends him against Sakaki using his first name—prompting the entire team to adopt it, reflecting their acceptance. His capacity for empathy grows, comforting Musa about race strategies and supporting Prince through training setbacks.
