There is no female protagonist, it is scary and supernatural, and it does not kill anyone. Don't wait until you finish, at least read the first seven chapters.
All ghosts are rampant, and the world is like a prison. The creatures retreated, and Yama closed his eyes.
Human life is like gravel, and there is no way to seek death. The whole world has turned into a paradise for ghosts.
Ghosts under the bed, tongue-pulling ghosts... Rules are everything.
If you want to survive, give everything you can and become something more terrifying than a demon.
——This is a story about a mortal who turns into an evil spirit.
