Emeraude cares for Gad so she revenges his failing to knock the Straw Hat Pirates off on them. She usually keep calm but minds whether someone determines definitely her race, and gets immediately into a panic and keeps away from antagonists as she is suddenly attacked.
Big Secret Treasure of the Seven Phantom IslandsEdit
For the moment that Wadatsumi was carrying the Straw Hat Pirates from Itu island to Yaw island, Emeraude jumped out of sea along with Saphir and Rubis, and then they sat on a stone of sea area between two islands. Their look appealed to Sanji, but they chose to attack him. Later, they said their names and positions in the Simon Pirates. Soon afterwards, She and two female fish-men started to against the Straw Hat Pirates for Gad's failure. Unfortunately, all three lost to them and just decided to jump into sea.
After the Straw Hat Pirates entered a cave in Yaw island, Emeraude, Saphir and Rubis battled them again. In the end of battle with them, they still failed. After that, a Master of the Waters wanted to attack them. She and others were protected by Gad who arrived afterwards it as well as Sanji and over the hump. Finally, to be based on Gad's second defeat, she and another three fish-men went away from a cave.
