The Girl Who Disappeared (2)

Sofony went to the residential building where her adopted sister Steffy was last spotted. However, all she found there was an empty premise her people had long cleared. There was no other trace left and she even had to resort to capturing a ghost using her newly gained ability to get some more details about what happened to Steffy.

'... King...'

Frightened by her aura as an immoral host, the ghost unconditionally cooperated. While covering under her gaze, that single word was written on the ground using black blood.

Sofony sunk into deep contemplation after seeing it. A second later, a thought flashed through her mind. She unknowingly held her breath.

King. Who could it refer to?
