She can be an adopted? Im sure hes not Brook's old captain's daughter though. If Oda is not deceiving us from that one panel, then the only one who has an afro hair in Rumba Pirates is Brook, and Brook is somewhat her recognized father.
But either way, isnt it confusing why Brook hasn't mentioned about having a kid not even in Thriller Bark... Not even once after the timeskip?
If she's his real daughter though, the only reason why he didnt recognized her must be because he left when she still was a kid and had no idea what she look like now. And when they met again back in Thriller Bark, she was already dead and was being used by Moria. And since her soul is not really her soul, she didnt recognize Brook who is already (looked) dead as well.
Maybe shes not aging anymore due to immortally and with what happen back in Thriller Bark
But now Im more confused on why she's remembering this now? Whats the trigger when shes been a huge fan of Brook since the timeskip?
Whatever it is though, I love what is happening now
Wait...Gunko has some memory of Brook but I don't believe that Brook is her father, probably it is the past captain of Brook (the one died from epidemic) is the father. Gunko and Brook's captain is quite similar. But I am very confused because Brook died 50 years ago, if Gunko is the daughter of Brook's captain that made her more than 50 years of age. Gunk doesn't look like 50, probably it has something to do with her power or experiment was conducted to her because her memories are not totally intact because she only remember Brook now.
