An overall extremely dangerous fighter, due to her status as a Key, she can break the limiter placed on humans. 17 years after the RagnarÖk, she becomes the leader of Anti-Government Organization Balhae.
Lee Soo-Jin has an athletic figure with short purple hair and lavender eyes. Her outfit as a Bishop of Nox consisted of a midriff baring grey sleeveless dress shirt with a yellow tie, baggy grey cargo pants and black heeled boots. Her accessories were wristbands and an eye patch over her right eye. When her Charyeok was activated Soo-Jin's hair grew to thigh length, she gained a veil and a black and red box and her revealed right eye glowed while bleeding.
After leaving Nox, she wore a red hoodie, dark shorts and a large brown backpack. Her activated Charyeok now took on a more armored appearance featuring a black pinstriped cleavage-bearing bodysuit, slim-fitting lavender and cyan pieces covering her arms and shoulders, a small green tie with black collars and armoured stockings held up by garter-belt straps.
Seventeen years after the events of RagnarÖk, Soo-Jin has now grown her hair out (resembling the style that forms when she entered her Pandora form) and she wears nothing but a black strapless bra-like garment, grey cargo pants and black boots.
Not much of her personality has been shown but when she met Jin Mo-Ri she seemed to be very excited. Although she is shown to be ruthless in battle, she can be quite serious when meeting higher ups. She has a hate for South Korea because of events that occurred in childhood and seems to want to destroy South Korea. She is also shown to have quite the sweet tooth, enjoying candies and sweets such as chocolate.
Soo-Jin is the granddaughter of the infiltrator that was captured by the government. While her grandfather was in captive, her mother and her grandmother were sent to the mines to work, there her mother got pregnant with her and gave birth to her.There, Soo-Jin developed a deep grudge for South Korea for the suffering she and her mother had to go through.
In the mines, while Soo-Jin was five years old, she's shown to have been favored by most of the older miners and was given food by them, even if it meant risking their lives.
One time when Soo-Jin sneaked into the mines that her mother and friends were digging in to give her mother a snack, the walls cracked and caved them in. Luckily, the airline still worked and the workers all agreed to take turns breathing in. Hours later, Soo-Jin was sleeping and her mother noticed that the other workers were advancing on them. Then Soo-Jin's mother demanded what they were doing, and their friends replied that they talked and let the mother-daughter duo to breathe through the airline, claiming that they had lived their life and that she should save her child. Hours later, the miners including Soo-Jin's mother died of lack of oxygen and helping Soo-Jin escape.
After being rescued by Bong-Sa and The RE Taekwondo Force, who later planned to kill her, much to Bong-Sa's displease. Bong-Sa refusing to allow them. When approached by his superior officer, Ryu, Bong-Sa summons his Borrowed Power, Sapsal Dog, to take Soo-Jin away while he fights his officer. 
She later wakes up in front of a military post, where she was indoctrinated and spent years learning her grandfathers ITF. Til the age of 16, she slaughtered her fellow officers, claiming to have taken up the task to infiltrate South Korea. Where she later joined the Nox.
Later in the series, she previously directs her mother's hatred and bitterness to Jin Tae-Jin and anyone associated with him. As the result, that grudge was carried over to his grandson, Jin Mo-Ri. She becomes a Bishop and seeks revenge by killing Jin Tae-Jin and anyone associated with him.
