The Lady of the Rainsworth household. Shalon is a member of Pandora and looks like a thirteen year old girl, although she is technically 23 years old. Her appearance does not change from her first meeting with Oz to after he came out of the Abyss because she has a legal contract with a chain, the black unicorn Eques.
Shalon and Break have a close relationship.
She was the one that discovered Break in a fatal condition after he came out of the Abyss. When she was young, she used to call Break 'Xarks-nii', as he was like a big brother to her. She wants to be of use to him. She also looks a lot like her mother, Shelly Rainsworth. While Oz and co. were taken into the Cheshire Cat's dimension, Shalon was abducted by Echo under the orders of Vincent Nightray, who poisoned Shalon in order to blackmail Break into destroying the memories from the Tragedy of Sabrie that Break attained from the Cheshire Cat. Despite Shalon protesting to Break to not destroy the memories, which took the form of the bell Cheshire wore around his neck, Break destroyed the memories in exchange for the poison's antidote. Shalon develops a queen complex when she drinks, which Oz strangely finds cool.
