Jeaha is the creator of Yureka. She sought Elca out in order to become her partner as a killer for the sake of avenging her parents, who committed suicide after being pushed into a corner. She also loves Jang-Gun. 

Jeaha 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 Lotto, 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.
