Lady Of War / Yamato Nadeshiko Inspiration

I'm working on a character concept who is a sort of an aristocratic character (In theory - I'm oversimplifying for the sake of asking my question) who is trying to be a young knight / samurai (culture she comes from is based on Korea in particular, but also other Asian cultures). She's very inexperienced, but trying to prove herself on both fronts. Sort of like Astrid, from Fire Emblem: Path of Radiance. However, I don't have too many other characters besides Astrid from which to draw inspiration regarding such a character. I was wondering if anyone could suggest some relevant characters and tropes to look at for inspiration purposes.

I'm not familiar with any such characters off the top of my head, but you might want to try asking for stories that feature characters like that in the Media Recommendations thread.

Thanks!
