Following an earthquake in an unnamed prefecture of Japan, a fault is discovered on Amigara Mountain, very close to the epicenter of the quake. On the slopes of the mountain, two hikers meet; a man named Owaki and a woman named Yoshida. The former assumes that they are both here to see the fault, which has captured the attention of the global press. Following the sound of voices to the fault, the two of them marvel at the strange sight before them: countless human-shaped holes in a rock face exposed by the earthquake.
