Hiroshi Fukuda, a first-year Seirin High student and basketball team center (jersey #13), combines a lanky 180 cm frame with spiky black hair, long eyebrows, and a habitual off-campus hat. His team membership originated from a literal interpretation of teammate Shun Izuki’s pun about requiring a "helper," showcasing his earnest nature. As a bench player in the "Seirin Mob Trio," he provides vocal court support until pivotal moments arise—most notably during the Winter Cup finals against Rakuzan High, where he guards Seijūrō Akashi to conserve senior players’ stamina. Earlier, he demonstrated unexpected competence in a rain-disrupted streetball tournament and a practice match against Tokushin High despite minimal playtime. Fukuda balances academic strength in physics with PE committee duties, leisure RPG sessions, kendama practice, and horror-averse camaraderie with friends. His kindness and diligence occasionally veer into naivety, particularly when accepting jokes at face value. Family life with his mother and two older brothers grounds him, while basketball mentorship extends to his admiration for teammate Wei Liu’s strategies. Dubbed "Fuku-suke" by coach Kagetora Aida, he embodies a motto prioritizing conscientious effort and respect, traits mirrored in his evolution from supportive reserve to clutch contributor during high-stakes matches.
