|Family|| Father (Deceased)|
Jae-ha is a skilled hacker and used her abilities to create an advanced program capable of creating AIs based on people. Her program was responsible for the creation of Yureka and Neogia and the recent addition of the Lotto A.I., this time not based on Jahea herself, but on Jang-Gun. This technology is highly sought-after by corporations such as Dexon. She becomes comatose after an attack with Elca, by sacrificing herself to save Lotto.
Jaeha is emotionally unstable, due to witnessing her father murdering her mother and committing suicide afterward. She was initially interested in Lotto after passively watching his adventures through Yureka, but gradually fell in love with him to the point of obsession. She eventually retreated into her mind when Lotto rejected her and only came out when Lotto called her name out.
Jaeha originally lost her parents when they committed dual suicide, and she vowed to take revenge. She became a hunter with the intention of switching to a killer. When she encountered Elca she joined forces to learn the ways of killing, though she never had killed anyone before or as of yet.
MEETING YUREKA ARC Edit
Hunting at Terror Tower Edit
Jae-Ha is first seen in the multiscanner room, naked in the Cyber Cafe, as Jang-Gun opens the door. He closes the door, but doesn't pay attention, knocking himself backwards from the surprise. She then gets dressed, accidentally dropping the Yureka ID card, and goes to Woon-Ha to get her card renewed. She looks over to see Jang-Gun avoiding looking at her directly, nervously, she simply smiles at him. She then leaves, thanking Woon-Ha.
