The Spread Shot of Sanae Kochiya from the world delirious with eternal summer (a Touhou LW original). She finds a mysterious jewel that causes the tide to rise. The Tide-Ebbing and Tide-Flowing Jewels are a pair of orbs that can control the ocean tides. They feature in many different legends and folktales. Sanae thinks they must be some kind of Izanagi Object!

The Focus Shot of Sanae Kochiya from the world delirious with eternal summer (a Touhou LW original). She finds a mysterious jewel that causes the tide to fall. It's said that the tide jewels are treasures from the Dragon Palace and that two islands sprung up where they were buried. Considering the apparent connection between the Dragon Palace and the Lunar Capital and how the Moon's gravitational pull largely determines the rise and fall of the tides... perhaps these jewels are actually devices used to manipulate gravitational forces!

A Spell Card of Sanae Kochiya from the world delirious with eternal summer (a Touhou LW original). She recalls one of her hometown's creation myths. Some of the legends and folktales passed down in Suwa contradict those told in the central regions of Japan. This is indicative of how the people of Suwa have historically asserted their independence from and equality with the central regions. They even have their own creation myth that describes how Suwa used to be a vast inland ocean that was then made habitable when a god tore down a mountain to let the water out. "Is that true, Lady Kanako, Lady Suwako?!"

A Spell Card of Sanae Kochiya from the world delirious with eternal summer (a Touhou LW original). This attack is reminiscent of life during the Age of the Gods. Chestnuts were a popular food source in the Jomon era (14,000 to 300 BC). It was formerly believed that people still hadn't developed horticulture or agriculture back then until evidence was found that they tended to groves of chestnut trees. Lately, some scholars believe they might have even started to cultivate rice during this time. It's theorized that clams are called "hamaguri" in Japanese because they are found on the beach (hama) and look like chestnuts (guri), even though there is evidence that suggests they were also eaten in the Jomon era. Incidentally, the kanji character for giant clams (oohamaguri) is shared with the mythical creature known as a mizuchi or shen that resembles a dragon. This surprising connection between shellfish and dragons can also be seen with triton sea snails. When a triton sea snail reaches 9,000 years of age after living in the mountains, in a human village, and under the sea, they transform into a draconic youkai called a shussebora.

The Last Word of Sanae Kochiya from the world delirious with eternal summer (a Touhou LW original). She unleashes a super cool and flashy attack on the beach. There is a legend about how an empress of Japan received the Ebbing-Tide and Flowing-Tide Jewels as a gift from the Dragon Palace on her return journey across the ocean. However, variants of this tale state that the jewels were actually gifted to the god Azumi no Isora or that the empress's little sister, Toyohime, who was also a shrine maiden, went to the Dragon Palace to receive them. "Toyo" was another word for "shrine maiden" in the southwestern regions of Japan, and "hime" means princess. Kanako claimed that the Toyohime in the tale actually referred to her, but that just made Sanae even more confused. This was because she had previously heard the legend of the two brother deities Hoori and Hikohohode. In that tale, Hoori, the younger brother, received two magical orbs from a princess of the Dragon Palace called Toyotamahime. It seems that all the complex connections between gods is a lot to wrap your head around, even for a living god like Sanae.
