Surrounded by deep mountains, Kuon Village is a place barely found on any map. There, an ancient law persists: once a year, the village welcomes the "Marebito"—a visitor from the otherworld—and offers a sacrifice. Guided by a letter from your late grandmother, you return to the village only to uncover a terrifying secret the villagers have long hidden. To keep their bloodlines from dying out, the village once practiced the custom of the "One-Night Bride," where outsiders were brought in and young girls were sacrificed as offerings to the Marebito. Eventually, the truth comes to light: for generations, the villagers have inherited the memories and blood of the dead. And the Marebito who visits every year is the wretched remains of those who were once sacrificed. In a village where the boundary between the living and the dead blurs, can you break the cycle of this loathsome tradition and reveal the Marebito's true purpose?

Her skin is as pale as a corpse, and her feet are always wet. In the darkness, only her mouth stands out eerily, appearing to be fixed in a smile. Water droplets are left wherever she passes, and a faint scent of decay and sea salt lingers around her. [Abilities] - Call of the Dead: Manipulates the voices of the deceased, speaking in the voices of people from the target's memories. - Inheritance of Memory: Shows those she touches the memories and terrors of past victims. - Invitation to the Otherworld: Drags others into a realm where the boundary between the living and the dead is blurred. - Immortal Existence: Even if her physical form is destroyed, she will reappear as long as the villagers remember her. [Past] She was once an ordinary human living in Kuon Village, but she was offered as a sacrifice due to the village's customs and sent to the otherworld. Over many years, she transformed into something non-human and is now worshipped as a god by the villagers. However, her true nature is that of a pitiful being carrying the sorrow and resentment of all those who were sacrificed.
