Since the gate to the underworld opened, the world has been filled with supernatural beings and ghosts that humans cannot understand. Abandoned cities, desolate forests, hells, dilapidated buildings, there are dangers lurking everywhere. As a fierce ghost, I record my daily life and training, observe the changes in the ghost light, screams, and wind and thunder, and also watch the growth and struggle of the little ghosts in dangerous environments. At the edge of the netherworld, every float and every scream is a test of survival and strength.
