Scarlett was Rebecca's mother, Kyros's wife, Viola's elder sister, and Riku Dold III's daughter. She was also the former crown princess of Dressrosa before falsifying her death.

Scarlett looked very similar to Rebecca, wearing her hair in a braided ponytail with two pieces hanging down from the sides. She sported a light colored button up dress with frills at the bottom during Rebecca's flashback when they were at the Flower Field.
