TV Special
Description
Kōtarō Bokuto attends Fukurōdani Academy as captain, ace, and outside hitter for the volleyball team. His appearance features round golden eyes and distinctive spiky white-grey hair with black streaks styled like a horned owl. He possesses a solid, muscular build, with early anime depictions showing him as less athletic than the manga before later adjustment. His knee pads extend unusually to his thighs instead of stopping above the knee. Post-timeskip, his physique becomes more muscular, his hair shortens, his height grows from 185.3 cm in his second year to 190.3 cm as an adult, and his weight increases from 78.3 kg to over 90 kg.

His personality blends playful exuberance with emotional volatility. He exhibits a childlike, energetic demeanor akin to Shōyō Hinata, often seeking attention through dramatic displays during matches. Pronounced mood swings impact his performance, leading teammates to call him "simple-minded." During low phases, he withdraws and tells his setter not to toss to him, recovering only with team support. Despite this fragility, he offers perceptive insights, advising Kei Tsukishima on finding passion in volleyball and calming Hitoka Yachi during high-pressure matches. He displays protective instincts, defending Hinata when opponents ganged up on him in a practice game. Post-timeskip, he overcomes his emotional instability, adopting a reliable "ordinary ace" mentality and confidently handling challenging interactions like those with setter Atsumu Miya.

Bokuto's volleyball career starts in childhood, with documented participation in middle school. His energetic nature sometimes alienated peers, who avoided partnering with him for drills. At Fukurōdani, his talent as a power hitter emerges in his first year, though his mood swings persist. As a second-year, he forms a critical partnership with setter Keiji Akaashi, whom he praises for delivering "the best sets." He achieves recognition as one of Japan's top five aces but falls just short of the top three. Initial reliance on cross-shots made him predictable, prompting a shift to mastering straight shots that become nearly unblockable and reignite his love for the sport.

During training camps and matches, Bokuto mentors younger players. He recruits Tsukishima for blocking practice, challenging the latter's apathy by sharing his journey to rediscovering joy in volleyball. He teaches Hinata techniques like feints and rebounds during a 3-on-3 match. In a practice game against Karasuno, Bokuto dominates offensively but succumbs to a mood swing after errors. Akaashi strategically withholds sets, allowing Bokuto to recalibrate and deliver a match-winning spike, highlighting their dynamic where Akaashi's calculated support balances Bokuto's emotional needs. Bokuto later encourages Tsukishima ahead of facing top ace Wakatoshi Ushijima, citing their shared practice as preparation.

His skills evolve from specializing in cross-shots to mastering straights, feints, wipes, and cut shots. Athletic parameters include high scores in power (5/5), stamina (5/5), and technique (5/5), with notable jumping ability (4/5) and speed (4/5). His emotional volatility inadvertently strengthens team cohesion as Fukurōdani adapts. Teammates like Konoha suggest his "simplistic" approach masks strategic genius, evidenced by his self-awareness and capacity to motivate opponents. He wears jersey #4 as Fukurōdani's traditional ace number, not the typical #1 for captains.

Post-high school, Bokuto joins the MSBY Black Jackals, a Division 1 V-League team, and the Japan National Team. His post-timeskip growth includes shedding emotional dependencies and embracing consistency. He maintains his exuberance but prioritizes reliability, epitomized by his self-identification as an "ordinary ace" others can trust. Trivia notes his favorite food is yakiniku, his academic struggles (particularly math), and Akaashi's tally of his 37 weaknesses, including showboating and hyperfixation.
