Err. There are many rape scenes, yes. Most of them happen to people in the background, as a consequence of war. They are rapes in the circumstance of mariage a couple of times. They are at least two occasions where a main female character is very close to being raped. There's a lot of sexual violence in general, though it's never condoned or portrayed in a shallow way.
I don't know if all of it is avoidable. So, I'm afraid to say it definitly could be a problem.
