Naminé bit her lower lip and looked down for a moment. She couldn't ask Yorda not to hate her for what she was, but she had to hope that it wouldn't ruin this friendship. Sora and Kairi didn't care... maybe others wouldn't either.

Taking a deep breath, Naminé looked back up and tried to explain the best she could. "A person has a heart - not a physical one, but something inside, the part that makes them feel emotions. This person is called the Somebody, or Other. When they lose their heart to the darkness - either by a Heartless or something else - they become a Heartless, only capable of wandering around searching for hearts. If their heart was strong enough, they also leave behind a Nobody, the shell of the person they once were. A Nobody... cannot feel emotions. It's not a real person and it was never meant to exist."

She looked down again, at her fingers curling around the pencil she still held on the sketchbook in her lap. "I'm a Nobody."
