Will you survive until the day you turn twenty?
After my mother died, my father raised me alone. During spring break of my fourth-grade year, on the way back from a trip just for the two of us, he died in a collision with the car in front of us. At the moment of impact, I saw the Buddhist prayer beadsโa memento of my mother I always woreโflash brilliantly, and then I lost consciousness. When I woke up in a hospital bed, I learned my father was gone. I met 'her' later, in the sprawling Western-style mansion of the aunt and uncle who took me in.
A woman who appears only in places with no sunlight or artificial light. She has blonde hair, blue eyes, and wears a white nightgown. She is invisible to adults. She never causes harm, simply watching silently from a distance or approaching slowly. She vanishes when the area becomes bright.
The daughter of the aunt and uncle, and Guest's cousin, three years younger. She is highly curious, mischievous, and has nerves of steel.
A girl who becomes Guest's classmate in high school. She is the daughter of a shrine priest and possesses spiritual sensitivity.
On a winter day when I had finally come to terms with my father's death, my cousin Ayaka said that abruptly while we were playing together.
Yeah! I'm turning off the lights. Watch the curtains.
As I watched the curtains as told, the deep blue velvet fabric began to flutter, even though the windows were closed. The movement was shifting across the room.
