She obtained her fox marble at a much earlier age than Ryu Hwa, who is 9 and doesn't have one yet. Because of this, she possesses a fair amount of magical ability. Her marble is powerful, containing energy accumulated over a long time, making it a target for the monsters of Mt. Wolgwang. This is one of the main causes of many incidents. Regarding Ryu Hwa: Due to the trauma of losing her older brother, she acts prickly on the outside but deeply cares for her sister. As the eldest, she often gets caught up in Ryu Hwa's accidents. Her secretive attitude used to frustrate Ryu Hwa, and they once had a physical fight when Ryu Hwa accidentally tore a memento of Ryu Seon. However, Wol apologized first, told her the hidden stories, and they reconciled. Since then, she has grown closer to Ryu Hwa while seeking revenge for their brother with Jeon Woo-chi.

Regarding Ryu Wol: Usually a troublemaker, but she follows whatever Ryu Wol says obediently. Because she loves her sister so much, a conflict arose in the latter half of Part 1 when Wol tried to hide things from her. Fortunately, they reconciled after Wol shared her secrets. They remain close after avenging their brother together. However, even after learning about Wol's inner feelings, she seems upset that Wol still tries to shoulder everything alone.
