Tetsuro Kuroo captains the Nekoma High volleyball team as its strategic middle blocker. His childhood began next door to Kenma Kozume when he was eight. Initially shy, Kuroo connected with Kenma through video games before introducing him to volleyball. He successfully convinced Kenma to join their junior high team and later supported him through first-year tensions with upperclassmen at Nekoma, ensuring Kenma stayed on the team. Physically, Kuroo stands 187.7 cm tall with a lean, muscular build and broad shoulders. His most distinctive feature is his messy black hair, spiked upward from his habit of sleeping on his stomach with pillows pressed against his ears. Narrow hazel eyes with cat-like pupils contribute to a sly appearance, his right eye often partially covered by his fringe. He wears Nekoma's red number 1 volleyball uniform during matches. Kuroo's personality blends laid-back charm with tactical provocation, earning him the nickname "Scheming Captain." He deliberately antagonizes opponents, like provoking Tsukishima at training camps to spur his competitive growth, though he apologizes if boundaries are crossed, as demonstrated with Daichi. Despite his teasing nature, he shows genuine care for teammates, especially Kenma, whose observational skills he consistently highlights as Nekoma's "brain." His leadership fosters team morale and camaraderie, seen in his boisterous laughter with friends like Bokuto. Throughout story arcs, Kuroo drives Nekoma's development. He showcases advanced techniques like the "personal time difference attack"—a delayed spike learned from televised matches and practiced since middle school—during early practice matches against Karasuno. At training camps, he mentors Tsukishima in blocking strategies and facilitates joint practices with Fukurodani Academy, emphasizing his commitment to strengthening rivals for meaningful competitions. His philosophy, "We are blood. Never stop flowing," underscores his focus on relentless teamwork and adaptability. As a player, Kuroo excels in reading opponents and executing precise blocks, capable of countering top spikers like Bokuto. His all-around skills include proficient receives and jump serves, vital for Nekoma's defensive playstyle. Post-graduation, he joins the Japan Volleyball Association's sports promotion division by November 2018, adopting professional attire while retaining his characteristic hairstyle. Key relationships define his journey: his foundational childhood bond with Kenma forms Nekoma's strategic core; his rivalry with Karasuno's Daichi reflects mutual respect; and his dynamic with Bokuto balances competitiveness with camaraderie. These interactions consistently showcase his role as a connector and catalyst within the volleyball community.
