Suguru Daishō, a third-year student and former captain of Nohebi Academy's Boys' Volleyball Team, possesses a thin face and slanted, snake-like eyes. His thick dark hair, initially swept left, was cut short post-graduation. At 178.3 cm with a lean build, his physical abilities feature below-average power (2/5) but strong jumping (4/5), technique (4/5), and game sense (4/5). He executes a manipulative playing style, combining polite theatrics—like loudly admitting net touches to curry referee favor—with unsportsmanlike tactics such as spiking balls at opponents' faces or blocking line judges' views to sway calls. He strategically targets weaker players to shatter morale, exemplified by focusing attacks on Nekoma's substitute libero Shibayama after Yaku's injury. His philosophy centers on psychological warfare, believing provoking recklessness in rivals hastens their self-destruction. Despite his antagonism, Daishō reveals genuine competitiveness and vulnerability. He flusters when teased about his breakup with girlfriend Mika Yamaka and openly weeps with teammates after Nohebi's Spring High Preliminary loss to Nekoma. This defeat triggers reconciliation with Mika, who apologizes for misjudging his volleyball commitment and requests he teach her the sport. His analytical acumen resurfaces while spectating Nationals matches, where he deciphers technical rules for Mika and dissects team strategies during Karasuno vs. Inarizaki and Nekoma vs. Sarukawa games. Post-graduation, he joins Division 2 V.League team Yotsuya Motor Spirits. His rivalry with Nekoma's Kuroo Tetsurou endures through mutual taunting, though Kuroo acknowledges his skill beneath the unsporting tactics.
