Daisy is a character from sixth One Piece movie. Daisy has very sharp hearing. She first demonstrated this when she called Luffy by his name although it was only the first time they met. She then tells them that she heard Deer man (Chopper) and the other Straw Hat Pirates calling out to Luffy while they were inside Lily Carnation. She was also able to hear the sound made by Omatsuri's arrows. Source: http://onepiece.wikia.com/wiki/Daisy_(Movie)
