Weakhoshi He then refers to her as "Weakhoshi" since he still considers her a crybaby. Shirahoshi also expresses profound worry for Luffy, such as when he lost a lot of blood from Hody's wound and when Luffy went after Caribou for the stolen valuables. She tries to reassure Shirahoshi that everything will be okay, but she too is worried about her brother. Luffy calls Weakhoshi "Princess" because of her beautiful appearance and he often uses this term when talking to women (except for his mother). There are several characters in One Piece whose names are taken from songs. Among them are Nami, who is named after a song by The Shins; Sanji, who is named after a character in a manga by Chizuru Takahashi; and Usopp, who is named after a character in a manga by Togashi Gensai. Also, Robin appears in some episodes as a child and sings songs to help pirates with their problems. These songs are called "Robin Songs". In conclusion, Weakhoshi's name is derived from a Japanese song.
