Suguru Daishō, a third-year student and former captain of Nohebi Academy’s boys’ volleyball team, carved a reputation for cunning gameplay and antagonism during the Tokyo Qualifiers for the Spring High Nationals. His snake-like features—slanted eyes, a thin face, and dark hair swept sharply to the left, later cropped shorter post-timeskip—complement a lean, 178 cm frame that belies his fierce competitive intensity. Daishō’s matches teem with calculated deception, blending courteous referee apologies with underhanded tactics like exploiting opponents’ weaknesses, obscuring officials’ sightlines, and psychological manipulation. He destabilizes rivals by targeting Nekoma’s Shibayama after Yaku’s injury and baiting Yamamoto into emotional errors. Despite unsportsmanlike methods, even adversaries like Kuroo acknowledge his sharp analysis and genuine volleyball skill. A rivalry with Nekoma’s Kuroo, rooted in vague junior high history, flares through barbed exchanges, including Kuroo’s mention of Daishō’s breakup with Mika—a jab that visibly unsettles him. After Nohebi’s qualifier loss to Nekoma, Daishō reconciles with Mika, who regrets ending their relationship over his volleyball obsession. The defeat cracks his composure, exposing vulnerability as he sobs alongside teammates. Post-graduation, he joins Division 2’s Yotsuya Motor Spirits, continuing his volleyball career. Attending the Tokyo Nationals as a spectator with Mika, he dissects plays and clarifies technical rules like legal ball retrievals under the net. Though his insights reveal tactical depth, lingering animosity surfaces when he mocks Nekoma’s third-years after their loss to Karasuno. Functioning as Nekoma’s foil, Daishō embodies pragmatism against their sportsmanship, his controversial tactics mirroring real competitive strategies to enrich the series’ volleyball portrayal. While his past remains sparse, his arc traces ambition interlaced with insecurity—evolving through his mended relationship with Mika and persistent athletic pursuits beyond high school.
