Jade has a lot of common sense and is open to the atmosphere around her; she is understanding of others and their needs. She has a lot of dignity and courage, however a softer side when it comes to discussing herself and when she is with the Luminary, who she protects as an older sister but also shares a much deeper bond with him than that. Even if she cannot be there to protect the Hero, she still has a strong desire to protect someone or something.

She is very strong in her beliefs and when she feels strongly about something, she will not take 'no' for an answer. She also has a lot of physical strength, especially with her legs as she resorts mostly to using kicks. During her youth, she is described as a tomboy who would often get scolded by her father for running around everywhere. This translates into her becoming a martial artist and a warrior.
