She is in the care of Gamunbi currently but it is unclear exactly how that came to be. Like Garam, she is reliant on him, frequently clinging to him when others are near however; due to recent circumstances, he appears to not remember who they are.
Gabi is a black-haired young girl who is always seen in white and gray traditional clothes and black pigtails.
Gabi has a shy, quiet personality around others though she is more lively when around Gamunbi. Like Garam, she is extremely submissive and easily manipulated. She and Garam were under orders to kill any of Bigak's group who tried to leave without permission, and was shown doing so without remorse.
It was stated that she and Garam are puppeteers rather than trackers, but that their tracking skills still exceed that of other chachaoong trackers.
They seem to have the ability to turn corpses into some kind of puppet, but their abilities have only been hinted at. Recently, they were forced by Bigak to perform this technique on a living chachaoong. The result has not yet been revealed.
Almost nothing of Gabi's history or backstory is known. At some point, she and Garam joined Bigak's group and came under the care of Gamunbi. Gamunbi was very much like a father to the two girls and they were complete distraught at his death. When Gamunbi killed himself, Gabi and Garam blamed Eunyul and went out to find him against orders.
They attacked Eunyul in the park with several of their puppets, but were unable to kill him. Eunyul destroyed their puppets, but hesitated over killing them since they were children. Before he could make up his mind, Ryuguheul showed up. Before Bigak could show up, Eunyul retreated. Ryuguheul was shown protecting the girls from a minor explosion caused by Eunyul's retreat, however they were killed a short time later by Bigak after they refused to return to his base.
