When she was seven, Nanoka was the sole survivor of a car wreck when a sinkhole opened up beneath the car she and her parents were traveling in. At the time, Nanoka remembers being pulled from the vehicle and seeing what looked like a shopping street burning, but there's no mention of the fire when she goes back to look up the accident. So when she hears girls in her class discussing ghosts at the location where the accident happens, Nanoka returns to the scene for the first time in years – and somehow finds herself standing on a street in the early twentieth century. She meets a strange young man named Mao, who claims that she's an ayakashi. <em class=de-emphasized>(from manga)</em>
