Blue Moon

Biodata

Background

Blue Moon was born on Fish-Man Island. Her mother died while she was young, and her father was a member of the Sun Pirates. After losing contact with him for two years, she left Fish-Man Island to see the outside world. 22

Her journey ended in betrayal. Blue Moon helped several stranded humans by towing their raft through the Calm Belt to the North Blue, only for them to sell her to slave traders once they were rescued. 22 Van later freed her from captivity during his raid on the slave operation. She immediately regarded him as her savior and pledged her life to him. 18

When Zephyr's Marines cornered Van's refugee ship, Blue Moon escaped with Van into the sea. Seawater weakened the Devil Fruit user until he could no longer swim or speak; she recovered him, secured him against herself, and carried him away from the pursuit. She later revived him with mouth-to-mouth resuscitation after he nearly drowned. 19 21

Blue Moon accompanied Van through the North Blue, including Sulfur-Iron Island, and chose to remain with him despite his enemies and the danger surrounding him. 25 Her mermaid body made extended life on land and aboard ships difficult, so she often remained aboard while Van went ashore. 27

After learning of Fisher Tiger's death and fearing for her father and the remaining Sun Pirates, Blue Moon chose to return to Fish-Man Island. Van accepted her decision, and Kuma used his Paw-Paw Fruit to send her there. 45 46

Personality

Blue Moon is compassionate, trusting, and intensely loyal. Her betrayal by the humans she rescued left her aware of the danger humans can pose, yet she continues to place complete faith in Van because he saved her from slavery. 22

She is energetic and sometimes inexperienced, as shown when her overly enthusiastic dive nearly causes Van to drown during their escape. However, she acts decisively in emergencies and does not hesitate to risk herself for him. 19 21

Her feelings for Van are openly romantic. She confesses her affection directly, seeks a future with him, and chooses to accompany him despite knowing his life is dangerous. 22 25 She also wants to become stronger so that she will not be a burden and can help him in the future. 33
