She has medium-length blonde hair worn with a small side ponytail. She has dark blue eyes. She is not a mermaid. Her finding out Hiroko's being a mermaid caused their relationship to worsen. Kokona transforms into Lime Pearl Voice(Enina's Identity) after she robs Hiroko's house. Luckily, she did not possess the Lime Pearl forever, as Enina's friends took it back by paralyzing her.
