Kouki Furihata is a first-year student at Seirin High and a member of the school's basketball team, playing as point guard with jersey number 12. He stands 170 centimeters tall and weighs 60 kilograms, with a birthdate of November 8 and blood type O. Furihata initially joined the basketball club because a girl he liked told him she would only go out with him if he became the best in one specific area. Though not deeply invested in basketball at first, he possessed fundamental skills and basic knowledge of the sport. His appearance features medium-length brown hair and wide eyes, with a height similar to Tetsuya Kuroko. Personality-wise, Furihata is frequently nervous and easily intimidated when facing strong opponents, particularly the Generation of Miracles players. Despite this anxiety, he demonstrates strong observational skills and court awareness that benefit his team. He exhibits a pessimistic attitude in early appearances, often expecting defeat against stronger teams, but gradually develops greater determination. Behind his timid exterior lies a persistent and hardworking nature, as he continues practicing diligently despite his fears and limitations. His basketball skills are generally average without outstanding physical attributes or advanced techniques, but he plays with caution and level-headedness that allows him to control game pace effectively. As a point guard, he focuses on supporting teammates rather than making flashy individual plays. Furihata's development occurs primarily during the Winter Cup tournament. He makes his official game debut against Kaijō High in the semi-finals, where his cautious playing style helps stabilize Seirin's pace during a critical moment and he scores his first official basket. In the finals against Rakuzan High, he is assigned to guard Seijūrō Akashi, a matchup considered overwhelmingly disadvantageous. Though struggling against Akashi's ability, he manages to score a basket through practiced ordinary shots. After being substituted out, he expresses frustration at his limitations but resolves to become stronger for future contributions. Off the court, Furihata is part of the library committee and enjoys hobbies related to railroads. His favorite food is omelette rice, and he carries bandages as a precautionary measure. He specializes in speed talking and performs best in biology classes. He lives with his parents and an older brother. Among Seirin's first-year players, he receives the most development and panel time despite being initially characterized as a minor character.
