Carol

Carol Masterson (キャロル・マスターソン, Kyaroru Masutaason) is Daddy the Father's daughter, whom Usopp meets at a goggle shop, in the Loguetown arc. Usopp was in a shop where he wanted to buy a "cool" pair of goggles for his adventures at sea, and, while he was trying to find his money, Carol came in and bought the goggles for her father. She later gave them to Usopp after they came to know each other.

Early One Piece
Carol, along with her father, are absent from the One Piece manga storyline. However, they were part of the Loguetown arc but were dropped so Oda could start off the adventure on Chapter 100. However they are both featured in the Loguetown filler episodes and the Loguetown Novel. There are differences between these two versions and both Daddy and Carol have varied appearances.
