Masamune Date is a prominent character from the anime Brave10, serving as the commander in control of the Oushu region. He is a soldier of fortune who delights in showing off and possesses absolute confidence in his swordsmanship. His primary motivation is to destroy the Kushi-mitama, a mystical artifact said to have the power to quell chaos, because he desires a world so troubled that it can be conquered through battle. He is portrayed as a powerful and imposing figure with a tactical mind and considerable combat expertise. Physically, he is recognized for his very long white hair, brown eyes, and the distinctive eyepatch he wears over his left eye, which is a symbol of a traumatic childhood incident that left a scar. Historically, the character is based on the real-life daimyo Date Masamune, and he is depicted as the head of the Date clan. In battle, he is ruthless and implacable toward his enemies, yet he also shows a softer side, such as a paternal fondness for children and deep loyalty to his allies. His combat style centers on his skill with a distinctive crescent-shaped blade, and he relies on both his physical prowess and strategic thinking to overcome opponents. Within the story, Masamune initially acts as an antagonist. He kidnaps Isanami, the shrine maiden, in order to seize the Kushi-mitama she carries, but he is thwarted by her rescuers. Impressed by the courage and skill of Yukimura Sanada's warriors, he develops a strong interest in Yukimura himself and later challenges him to a duel, which Yukimura wins using only a fan. This encounter marks a turning point: after a certain incident, Masamune begins paying careful attention to Yukimura, shifting from a straightforward enemy to a respected rival. His key relationship is with Yukimura Sanada, whom he views as a worthy opponent. Throughout the narrative, Masamune remains a free-spirited and ambitious warlord who cherishes the thrill of battle and seeks to live a life worthy of a great military commander.
