Rika is a slim, dark-skinned woman with black hair in cornrow braids. She is seen in a different outfit in every arc, but usually wears purple, comfortable clothing. She has long limbs and a slender waist.
Rika is the "big sister" figure to the Dark Moon Pirates. She puts up with the others more maturely than most of the crew in general. She has a tendency to try and help anyone she can, and detests fighting. Even though she tries to think of ways to get around fighting, she will quickly fly off the handle if someone is deliberately causing another person pain.
As a doctor, Rika has an impressive knowledge about human anatomy, and where she can attack a person to incapacitate them. She is also a trusted doctor among her crew, and has shown her vast medical knowledge when the others get seriously injured.
Rika also ate the Rifu Rifu no Mi, a Paramecia-type Devil Fruit that allows her to create as many leaves, of varying types and sizes, from her body as she desires and control them in a telekinetic manner. This should not be confused with a Logia-type power, as she cannot become leaves. She can use this ability for a quick attack, and raise a flurry of leaves to confuse the enemy to escape. She can also create leaves for medicinal teas or aloes.
