During a water-throwing festival, Miki shows Ukiya a new fortune predicting that Izumi will suffer a potentially fatal accident.
Ukiya shows the fortune to Mao who initially dismisses it, but also notices that the predicted date of the accident coincides with Izumi's upcoming diving competition.
Drought has resulted in severe water shortages, many people are afflicted by a mysterious illness that causes one's internal organs to petrify, and two meteorites land simultaneously in the mountains nearby, one of which is found and taken to an astrophysics laboratory.
At home, Izumi is shown a photographic slide of three petrographs by her older sister Yo, taken as part of her husband's research.
The first carving depicts an exploding supernova, the second an evaporating stone, and the third shows a shamanic ritual, the image of which Izumi likens to a person high diving.
At the center of the circle is a large, round boulder, its surface carved with petrographs resembling those shown in Yo's husband's research.
Later, Miki shows Mao and Ukiya a historical record referring to a village being struck by a drought and a "stone disease" after the appearance of two meteorites.
It also mentions that these events were only brought to an end after a person, chosen to restore balance, performed a ceremony that takes place on a full moon.
There, under the light of the full moon, Izumi psychically communicates with Mao and ruminates on why she survived the accident, before saying her goodbyes and walking into the river, eventually fading from sight.
