Akihiko Seguro, a second-year Nohebi Academy volleyball player, sports a light buzzcut, prominent brown eyes framed by thick brows, and an athletic, towering build. His name, rooted in the *seguro umi hebi* (yellow-bellied sea snake), aligns with Nohebi’s serpentine nomenclature. During the Tokyo Qualifiers against Nekoma, Seguro avoids direct taunts but mirrors the team’s calculated facade of sportsmanship. He targets Nekoma’s captain, Kuroo Tetsurou, with blocks that falter from mistimed leaps. While teammates provoke opponents or rally theatrically, Seguro’s responses to pivotal plays remain subdued, his motivations veiled behind disciplined adherence to strategy. Statistically, he balances raw power (4/5) with moderate agility—jumping, stamina, and speed each at 3/5. Tactical awareness and technical precision lag at 2/5, yet he seamlessly integrates into team tactics, syncing with celebratory chants and strategic plays without visible friction. His narrative arc stays anchored to the qualifiers, with no expanded backstory or external media presence, preserving his role as a steadfast, enigmatic contributor to Nohebi’s collective maneuvers.
