Overview
Yvonette is the protagonist of Demencia: (Re)bound & Unbound.
Appearance
Yvonette has short curly hair and black eyes. In the waking world, she appears as an elderly woman with light gray hair. She wears a long-sleeve green sweater with matching green shoes and a long gray skirt.
In the "dream" world, Yvonette takes the form of her adult self. Her hair is brown, and she wears a frilly sky blue and white dress with pink ribbons on the waist and collar. She wears pink shoes and a wide-brimmed blue hat with a pink ribbon to match.
Personality
The painting motifs along with the dancing figure world suggest that Yvonette is interested in the visual arts. It's possible that Yvonette is/was an artist herself, based on the portraits that can be found in her bedroom.
Past
Yvonette developed dementia at some point in her later life. By the time the game starts, her health has declined to the point where she cannot leave her room. She tries to recall her memories by putting herself in a trance.
