She is in the care of Gamun Bi currently but it's unclear exactly how that came to be. Like Ga Be, 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.
Ga Be is a black haired young girl who is always seen in white and gray traditional clothes and black pigtails.
Ga Be has a shy, quiet personality around others though she is more lively when around Gamun Be. Like Ga Ram, she is extremely submissive and easily manipulated. She and Ga Ram were under orders to kill any of Bi Gak's group that tried to leave without permission, and was shown doing so without remorse, after Gamun Be died.
Almost nothing of Ga Be's history or back story is known. At some point, she and Ga Ram joined Bi Gak's group and came under the care of Gamun Be. Gamun Be was very much like a father to the two girls and they were complete distraught at his death. When Gamun Be killed himself, Ga Be and Ga Ram blamed Eun Yul and went out to find him against orders.
They attacked Eun Yul in the park with several of their puppets, but were unable to kill him. Eun Yul destroyed their puppets, but hesitated over killing them since they were children. Before he could make up his mind, Ryu Guheul showed up. Before Bi Gak could show up, Eun Yul retreated. Ryu Guheul was shown protecting the girls from a minor explosion caused by Eun Yul's retreat, however they were killed a short time later by Bi Gak after they refused to return to his base.
It was stated that she and Ga Be 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 Bi Gak to perform this technique on Leon though he was still alive. The result has not yet been revealed.
