In her youth, Nahkwol tragically lost both her parents who fell in the line of duty, while battling demons.
As a result, she was taken under the wing of her master.

Due to health issues she had as a child, her master urged her to lead a life that differed from her parents' perilous path.
However, Nahkwol chose to defy her master's counsel and set out to be a demon hunter.

During her demon-hunting endeavors, she encountered Siho, who had fallen victim to a demonic possession.
She trained Siho and took her as a Familiar, so Siho would accompany her everywhere.

Later on, she resorted to using a forbidden incantation on Siho.
Consequently, both her body and her strength grew weaker.
However, Siho went on a rampage and encountered humans.

Ultimately, she had to seal Siho away and, tragically, met her demise.
