August in the Water

Izumi Hazuki transfers to a new high school in Fukuoka, where she quickly makes friends with two boys, Mao and Ukiya. Both boys become infatuated with her, and Ukiya consults his fortune teller friend Miki to see whether he might have a chance with her. Miki curtly informs him that their signs are not a good match. Mao and Izumi begin to steadily grow closer, spending time together as Mao drives Izumi home from her high dive training.

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. Meanwhile, the city is plagued by strange events. A 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. Yo suggests that the petrographs are related to current events.

The day of Izumi's competition arrives. Mao and Ukiya watch nervously from the stands as Izumi takes her dive from the platform. As she falls, the surface of the water briefly appears to turn to stone, causing Izumi to falter and slam into the water. Mao dives into the pool and rescues her, whereupon she is rushed to hospital. There, doctors inform her sister that she has fallen into a coma and may not survive.

Fortunately, Izumi soon regains consciousness and returns to school. However, her personality after the accident is markedly different. She talks of having a raised awareness of herself and the surrounding environment on a subatomic level, and becomes increasingly preoccupied with the mountains near the city. Mao and Izumi later hike to the mountains, where they find a stone circle hidden among the trees. 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.

Some time later, Mao receives a phone call from Yo, telling him that Izumi has gone missing. While Mao looks for Izumi, the police search for a man believed to be in possession of the missing meteorite, who has murdered a scientist and stolen the second meteorite from the laboratory. Eventually, both Izumi and the man are found in the mountains, lying together on the boulder along with both meteorites. Later, under questioning by a doctor, she explains that the man is a member of a tribe of stone beings who wish to take over Earth and return it to stone, and that she must take measures to prevent this from happening. The doctor suggests to Yo and Mao that Izumi may be suffering from sudden schizophrenia brought on by the shock of the diving accident. Izumi later returns to school, where rumours have spread due to a magazine article suggesting that Izumi can psychically communicate with dolphins and plants. 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.

Yo collapses after contracting the petrification illness and is hospitalised. Mao meets Izumi at the hospital, where she tells him that she can't wait any longer and must take action. She leaves the hospital followed by Mao and makes her way to a nearby river. 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. The next morning, storm clouds appear over the city as Mao makes his way to the stone circle. He is later found unconscious atop the boulder and taken to hospital, where he is diagnosed with amnesia, having lost his memory of the previous night. Rain begins to fall and the drought ends.

After the rain storm passes, many people recover from the illness. News about the petrographs and Miki's record spreads worldwide, and scholars come from various countries to study the stone circle. Mao volunteers in the study, hoping to find clues about Izumi's disappearance. He eventually becomes a researcher studying special remains found around the world, using a diary Izumi had kept as the basis for his studies. Years later, an elderly Mao visits the stone circle, now named the "Hazuki Circle", and lies down on the central boulder. As rain begins to fall, Izumi appears before him, unchanged in the years since her disappearance. The two embrace, and then vanish.
