Shōhei Fukunaga, a second-year wing spiker for Nekoma High School's volleyball team wearing jersey number 6, stands 178.3 cm tall and weighs 68.3 kg. He possesses pale skin, short black hair with cowlicks at the nape of his neck, and wide, cat-like eyes featuring small pupils. His posture is typically relaxed, with slouched shoulders and bent knees, often gesturing with both hands. Despite being a regular player, Fukunaga rarely speaks, usually offering only brief verbal responses like "Yes" or "Okay," which earned him the nickname "silent big point scorer" during Nationals. He harbors a strong interest in comedy, frequently formulating humorous remarks internally but laughing quietly to himself without voicing them. His calm demeanor remains unshaken during intense matches; he was even observed listening to stadium music while playing against Karasuno. Fukunaga proactively resolves conflicts, demonstrated during his first year when he halted a fight between Kenma Kozume and Taketora Yamamoto by dousing them with a bucket of water, an action praised by upperclassmen and earning peer respect. He repeated this intervention method in later teammate disputes. On the court, Fukunaga displays balanced abilities: power, jumping, stamina, and speed rated 3/5, while game sense and technique are both 4/5. He possesses exceptional receiving reflexes, handling powerful serves from Tobio Kageyama and float serves from Kei Tsukishima, alongside a willingness to make dynamic saves, such as leaping over tables. As a spiker, he precisely manipulates ball trajectories to target hard-to-reach court areas like the backline—a talent commentators described as "phantasmal." His serves strategically target specific players like Shōyō Hinata. His relationships within Nekoma center on long-term connections with fellow second-years Kenma Kozume and Taketora Yamamoto, dating back to their first year. He supports Kenma during exhaustion and collaborates with Yamamoto in celebratory gestures, like attempting to hug Kenma after victories. Fukunaga lightens team tensions, evidenced when he made Kenma laugh during a timeout against Karasuno by quipping, "No one dies when playing volleyball." Key moments occurred during tournaments: at Spring High Preliminaries, he scored consistently against Fukurōdani and Nohebi, though the latter match involved disputed line calls against his spikes. During Tokyo Nationals, he secured match-winning points against Kiyokawa and Sarukawa, praising Kenma's set after the latter. His performance peaked against Karasuno, contributing receives, spikes, and comic relief—notably making a pun about Tsukishima's block ("Did he just jump or fly? My, my, so fly") that confused a referee. The match concluded with Fukunaga tearfully exiting after Nekoma's loss. Post-graduation, Fukunaga pursues a dual career as a comedian and part-time restaurant chef, reuniting with former teammates at Kenma's home. His journey reflects progression from a reserved first-year to a nationally recognized player leveraging strategic versatility and understated leadership.
