Nina is a doll in the shape of a one-eyed monster. She is timid, but can sometimes show a strong side. Sometimes she likes to be cute but scary and scares her friends with it. Her favorite holiday is Halloween, and as a royal descendant of Luiio, the toy kingdom, she's diligent about keeping up with all the celebrations. Currently, she is being dragged around by her friends and experiencing all kinds of things in Luiio.
