@Smoothralph She's not, when brook first joined the Strawhats officially he mentioned he was the leader of a garrison of some kingdom. She may have been the princess of that kingdom or something
@JusticeforDonut Yeah, i was talking to my friend a week ago he told me that Brook probably has a daughter based on a scene. So i thought he did, but i'm not sure bc i need more info maybe she was a fan of him.
