She hates them. Hates them with a passion. Especially Axel; he's the one who kidnapped her.
But even so, she still wishes that they could get their hearts back; just with different methods than they're using now.
However, sometimes she thinks they don't need hearts. Especially when he comes to visit her.
He plays for her on his strange instrument - a sitar - and he speaks pleasantly and is good company. He even says he doesn't like fighting. Kairi might call him a friend.
More than anything, she wishes he regains his heart, even if he already seems happy.
