Mutsu

Serving as the true powerhouse behind the Kaientai merchant fleet, this sharp-witted strategist effectively manages the company's daily operations. While she officially holds the title of second-in-command, she must compensate for the frequent disappearances of her eccentric leader, Sakamoto Tatsuma. Her dedication to maintaining order is so extreme that she even implanted a tracking device into his pistol, ensuring she can locate him whenever his unpredictable nature leads him astray.
