Coco (ココ, Koko?) Voiced by: Satomi Arai is a fictional character in the manga and anime series Mermaid Melody Pichi Pichi Pitch.

Coco is the Mermaid Princess of the South Pacific Ocean and the Keeper of the Yellow Pearl. She is also friends with the orange Mermaid Princess Sara. After Sara was left by Taro, Coco tried to be there for her, but she lost control of her pearl and caused great damage to both her and Coco's kingdoms.

Notes: In the manga, her kingdom was never harmed by Sara's pearl's power.

Later, Sara released Gackto from imprisonment and Coco was captured until she was rescued by Lucia, Hippo, Rina, Hanon and Caren. Her capture makes her the first mermaid princess to become kidnapped by the sea monsters.
