I'll go with Flag as in flag officer for now because it seems more likely given her nickname. Maybe I should ask him...
Major Tokugawa Yuki, age 19, of the Fusou Maritime Self Defense Force, assigned to the flight group aboard the aircraft carrier Youryuu. Her callsign is Lancer 1, and her TAC name is Flag. Her Strikers are F-14AF carrier-based attack units, and her standard armaments consist of the Type 89 rifle, the P226 9mm handgun, etc. Her familiar is the tanuki. As a high-ranking officer in peace time, she immersed herself in desk work and seemed like something of a timid wallflower, but her personality shifts drastically when she's wearing Striker units; this change has earned her the nickname The Bold Shogun (n.b. like the TV show). In fact, she actually is a descendent of the Tokugawa line, which controlled Edo during the Bakufu period. Her role in the Persian Gulf was overshadowed by her wingman, Captain Houjou, but she was a major player in the defense of the Khafji oil field in the opening of the war and was promoted to Lieutenant Colonel when the conflict was over. "Ummm... Let's all work hard to help each other, okay! Okay?" PS: "Nobunaga returned safely from Honnouji" I looked into it, and it's true. Ahhh, I did it... (despair) (n.b.: referring to a Nogami Takeshi doujin where a witch version of Mori Ranmaru saves Oda Nobunaga during the Incident of Honnouji.)
