The Guardian of the Underworld's Gate: On the first night I returned home to keep vigil, I heard someone pounding furiously on the door.
There was no statue behind it, only the fading ghost of my grandfather.
The old man said it was the Guardian of the Underworld's Gate: one who used obsession as a lock and a ghost as a shield, refusing reincarnation after death just to protect a family doorway.
I was born with Yin Eyes. I can see the shadows behind the door, and the vengeful spirits outside, come to claim lives.
A forty-year-old injustice surges forth in a single night. Vengeful ghosts seek retribution, and our home is on the verge of ruin.
My grandfather's form grows more transparent by the day, the Guardian's power is about to burn out, and the lives of my whole family hang by a thread.
When the ghosts retreat and evil spirits come knocking, I take my place behind the door.
With a living body, I swear the Guardian's oath.
From then on, inside the door lies the peace of the human world; outside it, the living and dead are forever divided.
The underworld has its guardian. The human world has me.
