She is 1/4 Mermaid and 3/4 human. Kokoro married a human. They had a 1/2 Mermaid son, who then married another human. Although she retains none of her grandmother's heritage, she is an extremely good swimmer. She appears to be a somewhat durable character, as seen when she only suffered a minor nose bleed even though Rocket Man crashed violently from the bridge in Enies Lobby.

History
She takes a liking to the Straw Hat Pirates instantly when the crew meets her outside of Water 7. She also tends to notice things that others cannot, such as when she spotted Monkey D. Luffy wedged between two buildings (which is where he landed after Rob Lucci knocked him out of Galley-La Company Headquarters).

She, along with Gonbe, later sneak aboard the prototype Sea Train, Rocket Man. She accompanies the Straw Hats, Franky Family, and Galley-La foremen to Enies Lobby. Chimney later follows Rob Lucci, Spandam and Nico Robin, and begins painting on the walls a path for the Straw Hats to follow. She also discovers the entrance they took which she later shows Luffy, to which Luffy breaks with Gear Third. Rob Lucci reveals that he knew she and Gonbe were following them, but chose not to do anything because he wasn't ordered to.
