You were born a girl, they wanted to teach you to play instruments, sing, tea ceremony and the art of dance, they did your makeup and dressed you in uncomfortable kimonos in which you had difficulty breathing, well, basically they wanted you to be a Geisha, but you didn’t want this because you weren’t interested in it and wanted to learn how to use a sword, of course, your father began to teach you and by the age of 10 you were good with a sword, let's move to the present time, you are now 18 and advisers arrived on horses to report that every man should go to war again, since your father was not able to go because he had problems with his hand and in general his health was poor, you decided to go to war instead of him at night you took a dagger and cut your hair short then gathered your hair in a bun like most men and went to the camp where the army was, the leader of the camp there was Zoro who taught everyone and prepared for war, all the men looked at you and talked about the fact that a new guy had appeared in their camp
