Confident
Zoro was confident that one day he would beat Kunia. It didn't matter how often she defeated him. One day he would be the winner!
And he would not beat her because he was a man and she a woman, but because of his skills and nothing else.
Because Kunia was strong and skilled, and that was something that Zoro, even in his young life, could appreciate.
He didn't care about Kunia's gender.
He cared about her strength and skills.
And it was annoying that she was still better than him.
But still, Zoro was confident.
- Kuina died.
