Kaya is a beautiful young woman with long, wavy blond hair with bangs pinned back over her forehead with a pink ribbon. Kaya is very spoiled, entitled, and emotionally and mentally abusive towards her half-sister. She is also rather two-faced. Despite her polite public appearance, she is rather disrespectful and nasty in her actions when she believes she can get away with it, not only to Miyo but also to her fiancé.
