When the midnight bell tolls, you receive a black invitation from the abyss:
“Door Pusher Ning Qiushui, your Blood Door has opened.”
A black card that cannot be discarded or destroyed dragged illustrator Ning Qiushui into a bizarre world beyond comprehension. An abandoned phone booth, a middle school trapped in eternal night, an ancient funerary town that follows ancient rites... Behind each Blood Door, known as a “Ghost House,” lie interlocking rules that mean certain death and dangers without end.
Here, survival isn't an instinct. It's a riddle that must be solved. Make a mistake, and you'll become part of a Ghost House, wandering there for eternity.
From struggling to survive to actively seeking the truth...
