As a mermaid, Hiramera can breathe underwater, speak to fish via sonar waves, and they are generally considered the fastest swimmers in the world. She also appears to be a skilled dancer.Like all other mermaids, Hiramera is kind and caring, and is apparently fun loving. She even seems to like Sanji like rest of her friends When the Straw Hat Pirates were accused of kidnapping mermaids, Hiramera was the one to defend them, saying they seemed like nice people and are Camie's friends after,
