She has discovered that she is different from others since she was five years old. She has the ability to travel between the world of ghosts and gods and the real world, and this ability also allows her to live a thrilling and interesting life.
She has a mother who has been traveling around the world and a father whom she has never heard of or seen, so she is used to loneliness, darkness, and wandering.
When she just entered college, she once met four people with the same abilities as herself in the world of ghosts and gods. They were a young boss of a game company, a high school student, a travel reporter and a university teacher. From then on, the five of them had a series of emotional entanglements and experienced a fantasy journey together.
