While he is a strong and capable leader who has done well to consolidate the power and prestige of the Marines, Sakazuki would be best categorized as an extremist and highly dogmatic. He is an adamant believer in Absolute Justice and is ruthless in his maintenance of it, his derived motto being "Thorough Justice" (徹底的な正義, Tetteiteki na Seigi?). He has a stern, dead-serious disposition, is grim, expressionless, and was the most ruthless out of three admirals.
