Hakurou, once an unnamed ogre, stands as a cornerstone of the Jura Tempest Federation. Grandson of master swordsman Byakuya Araki, he honed his craft under his grandfather’s tutelage before rising to become the martial instructor for the Ogre Tribe’s royal guard. Defying the typical ogre lifespan of 100 years, his mixed heritage and transformation into a Kijin—triggered by Rimuru Tempest’s naming—extended his life beyond 300 years, reversing his aged form into a prime, silver-goateed warrior with sharpened features and ivory horns. Renowned as a swordsman centuries before his evolution, Hakurou once mentored Gazel Dwargo and now leads Tempest’s military training, prioritizing disciplined martial prowess over innate abilities. His combat expertise merges centuries of experience with refined techniques like Thought Acceleration, Future Prediction, and the Heavenly Eye, enabling precise analysis and anticipation of opponents. Though classified as A-Rank in magicule capacity, his technical mastery pushes his threat assessment to Disaster-Rank in human terms. Hakurou embodies calm authority tempered by exacting standards, bristling at the label "old man" with threats of intensified drills. A tactical mind allows him to dissect enemy strategies mid-battle. Discovering parenthood ignited an overprotective streak, driving him to push his daughter toward Benimaru while openly scowling at delays in their courtship. The film *Scarlet Bond* revisits his past through Hiiro, a surviving ogre kin, as they navigate clashes involving the Kingdom of Raja, showcasing his dual role as diplomat and warrior. He wields Samegumo, a Legend-grade cane-katana forged by Kurobe, symbolizing his mastery. Blessed with Tempest’s divine protection and bearing the Sword Saint title, Hakurou remains a linchpin strategist and mentor, bridging ancestral traditions with Tempest’s dynamic evolution through wars and alliances.
