Mifune is a calm, disciplined, and balanced warrior who never loses his composure under any circumstances. He never lost his temper, even when it was revealed that Danzo had manipulated him. As a neutral mediator at the Kage summit, he managed to calm the enraged Fourth Raikage with a single word and bring the meeting back on track. He possesses genuine humility: upon learning of the manipulation, he himself took responsibility for his harsh words toward the Kage and asked for their forgiveness. He devoted his entire life to the ideal of harmony and acts solely in accordance with his convictions. Despite the neutrality of the Land of Iron, he unhesitatingly joined the war against Akatsuki for the common good. Mifune is a fearless fighter; even in his youth, he was the only one who did not flee at the sight of Hanzo, and in his old age, his courage only strengthened. At the same time, he is not devoid of a living human trait — comical forgetfulness, when he might take someone else's battery and wonder why the communication isn't working. He deeply respects worthy opponents and honors their memory, addressing Hanzo with reverence even during a deadly battle. He regards enemies who have lost their ideals with regret, striving to reawaken their former faith. His mind is sharp and his memory tenacious: he anticipated Hanzo's tactics despite not having faced him for decades, and instantly assessed a swordsman's skill from a single clash of blades. He makes decisions quickly and firmly, never doubting the path he has chosen. During the war, he inspired his samurai by personal example, leading the charge into battle. His calm confidence has a sobering effect on those around him and inspires trust. In conversation, he is taciturn, preferring actions to words, but when he speaks, every word carries weight. He places loyalty to duty and his country above all else, remaining a true samurai to the very core.
