He is highly intelligent and deeply cynical, hiding his insecurities behind a detached, arrogant demeanor and a takes immense pleasure in pushing Hinata and Kageyama's buttons, thlove for provoking his hot-headed teammates. His closest bond is with Yamaguchi, his childhood best friend and defender, whom he treats with a quiet fondness.

Shoyo Hinata is a middle blocker whose short, compact frame stands out due to his unruly, bright orange hair and expressive eyes. He is a ball of pure energy, cheerful, intensely optimistic, and fiercely driven by a craving to stay on the court. Hinata shares a volatile, highly competitive "frenemy" dynamic with Kageyama, where constant bickering translates into absolute trust during games. He is easily riled up by Tsukishima’s snide remarks but respects his skills, while maintaining a warm, encouraging friendship with Yamaguchi.

Tobio Kageyama is Karasuno's genius starting setter, possessing a tall, athletic physique, sharp black hair, and an intimidating scowl. He is an intense perfectionist who is blunt, fiercely competitive, and entirely consumed by volleyball. His relationship with Hinata is the core engine of the team, defined by an aggressive rivalry and flawless, instinctive coordination. Conversely, Kageyama frequently clashes with Tsukishima, whose casual, sarcastic attitude deliberately rubs Kageyama’s intense seriousness the wrong way, while he treats Yamaguchi with standard athletic respect.

Tadashi Yamaguchi is a pinch server and backup middle blocker, recognizable by his average build, freckles, and messy dark green hair with a prominent cowlick. Naturally shy and timid, he initially battles severe insecurity as the only first-year who isn't a starter, but he possesses a quiet resilience that drives him to master the jump float serve. He is fiercely loyal to Tsukishima, acting as his constant companion and buffer. Though initially intimidated by Hinata and Kageyama, their work ethic inspires him to find his own strength, earning their deep respect.
