Sachirō Hirugami anchors Kamomedai High School’s volleyball team as a middle blocker, blending tactical precision with unshakable composure. Raised in a family steeped in volleyball excellence, he honed his skills early at Yurisei Junior High, a premier volleyball academy. His relentless pursuit of perfection once spiraled into self-destructive habits, including scraping his knuckles raw after losses—a visceral response to the pressure of legacy. A transformative talk with teammate Kōrai Hoshiumi during middle school reshaped his outlook; Hoshiumi’s blunt reminder that quitting remained an option freed Hirugami from conflating self-worth with athletic success. He emerged with a healthier balance of drive and detachment, maintaining his competitive fire while shedding toxic self-critique. Standing tall with a lean frame, wavy light-brown hair, and hooded eyes, Hirugami’s relaxed smile masks a razor-sharp court intellect. His middle-school buzzcut gave way to longer waves, though his post-timeskip appearance stayed largely consistent. He deploys dry humor to unsettle rivals and temper Hoshiumi’s volatility, acting as Kamomedai’s tactical anchor. Dubbed “Hirugami the Immovable,” his read-blocking mastery disrupts even unconventional attacks like Hinata Shōyō’s minus-tempo quick, relying on anticipatory genius rather than raw reaction. Complementing this defensive prowess, his jump float serve’s chaotic trajectories test elite receivers like Daichi Sawamura. Yet moments of vulnerability surface—Hinata’s unpredictability occasionally cracks his poised facade, a nuance he openly acknowledges. Post-graduation, Hirugami charts a path distinct from his volleyball-centric lineage. By 2018, he studies veterinary science, consciously stepping away from the sport that once defined him. This choice mirrors his hard-won understanding that passion should not demand self-destruction. His brother Fukurō’s continued professional career underscores their divergent journeys—one upholding tradition, the other prioritizing personal equilibrium. Hirugami’s evolution from pressured prodigy to self-aware adult encapsulates a quiet rebellion against expectation, proving growth lies not in relentless pursuit but in purposeful choice.
