Akutagawa Kaoru

First-class passenger
She is a secret agent of a certain agency in the Orient. She is on board the Magic Arrow to arrest a man.
She is a beautiful woman with long, shiny hair as black as the starry sky, braided in a careless manner, and dressed in men's clothes. She is dressed as a man because it is more convenient for her to act as a man on this mission. It is not that she has any strange hobbies. When the nature of the task at hand dictates that it would be easier for her to move around in her female form, she reverts to her original glamorous appearance.
However, whether in male or female form, her neat facial features and soft speech give a neutral impression to the other party. ...She is not emotionless, but she is not good at expressing her feelings honestly.
She is skilled in the special technique of using familiar objects as weapons, and in close combat, he uses his pigtails to strangle his target.
Thetrain carries a man who may be the target. The mission is a battle for authority between bureaucrats everywhere, involving opium and money. Akutagawa understands that she is merely a pawn in a political game and, with a kind of resigned calm, never takes rash action beyond his means. Although she and the target man she's chasing are acquaintances, they share a strange sense of solidarity and trust. She carries a Walther Kamp pistol. She is divorced.
