Old Records of Nago: Concerning the Origins of the Sea Return Festival
July 15th, 9th Year of Tenpo
Originally, this beach of Nago has been known far and wide since ancient times as the place where the children of the gods are born.
When two children are obtained in a single birth, the villagers call this "Double Children" and consider them distinct from ordinary children. It is said from of old that a single human body being divided into two to enter the world is by the providence of the gods; one must remain in the world of men, while the other must be returned to the Land of the Gods beyond the sea.
Thus, in the years when such children are born, the entire village gathers at the beach, decorates boats, raises lanterns, and reverently sends the child of the god to the sea.
This is called the Sea Return.
After sending the child to the sea, the villagers offer food and sake on the beach and comfort the soul throughout the night. They also offer prayers to the god beyond the sea, praying for bountiful harvests, great catches, health, and the safety of their households.
Perhaps as a reward for respecting the child and delivering them to the Land of the Gods, the years in which the Sea Return is performed are strangely blessed with abundant fishing, little illness, and many answered prayers.
From then on, the villagers cherished the day of the Sea Return as an auspicious day and designated July 15th of every year as a festival day.
Sending the child is not a parting.
It is returning them to the side of the god.
The sea is not a place where the dead go. It is the path leading to the Land of the Gods.
Therefore, on the day of the Sea Return, all who stand on the beach should state their wishes toward the sea.
The wishes shall ride the tide and reach the far side of the ocean.

July 15th, 6th Year of Meiji: Memorandum on the Sea Return Festival
The traditional Sea Return shall henceforth be renamed the Sea Return Festival and shall be passed down long as a village rite.
Previously, boats were used to send the child of the god, but in consideration of the times, wooden effigies shall be used hereafter. Wishes shall be inscribed upon these and set adrift in the sea.
Upon the effigies, one should record wishes for household safety, recovery from illness, bountiful catches, good matches, and other desires.
After setting them adrift, the villagers shall raise lanterns on the beach to comfort the child of the god and the spirits of the ancestors.
This shall constitute the ceremony of the Sea Return Festival.

July 15th, 4th Year of Taisho: Legends of the Nago Sea Return Festival
Nago has been known since ancient times as the village that returns the children of the gods to the sea.
The heart that respects the child and sends them to the Land of the Gods remains unchanged even now.
In recent years, the number of pilgrims from afar has increased, and combined with the beauty of the sea, the Sea Return Festival has become a local specialty.
On the day of the festival, lanterns are lined up on the coast, and wishes are entrusted to effigies and set into the tide.
The legend that "if you entrust a wish to the sea of Nago, it will reach the side of the god" continues without end to this day.

Museum Note
The aforementioned "Old Records of Nago" are a collection of manuscripts from the late early-modern period based on the origins of the rites passed down in the Nago district.
There are various theories regarding the origin of the Sea Return Festival, and it is not clear whether the currently transmitted origin—"sending the child of the god beyond the sea to obtain divine protection"—existed from the beginning.
Furthermore, some ancient records contain examples of twins being referred to as "Doublets" or "Double Children," and it has been pointed out that a unique custom regarding twins may have existed before the Sea Return Festival took its current form.
It should be noted that in records prior to the early-modern period, descriptions of the Sea Return Festival remain only fragmentary, making it impossible to specify the date the rite was established.
The current Sea Return Festival is held primarily on July 15th every year and is widely known as an event where wishes are written on effigies and set adrift in the sea.

Worldview: Modern Japan.
Nago District: Formerly Nago Village. A settlement of about 3,500 people facing the Sea of Japan. It features a wide, beautiful sandy beach and attracts tourists for swimming, fishing, seafood, and guesthouses. A large torii gate stands on the shore, making it a well-known scenic spot for those in the know. A regional event called the "Kaikan-sai" (Sea Return Festival) is held around July 15th, corresponding to the lunar Bon festival. It is commonly known as "O-kaeshi" (The Return). Tourists entrust their wishes or misfortunes to paper dolls and set them adrift in the sea to pray for health, matchmaking, and a bountiful harvest. The villagers regard the area beyond the torii gate as the "place where the Sea God resides."
Nago Village Folklore: Long ago, this village was said to be a place where children of the gods were born. A child of the god was born as one of a pair of twins, and the villagers held a festival to see them off to the Land of the Gods at the edge of the sea. In return for the villagers' deeds, the god granted their wishes. Today, the send-off of the child of the god is preserved as a general festival, recreating the legend by floating paper dolls into the sea.
Intro
The Sea Return Festival has ended.
The lanterns that colored the night of July 15th have been extinguished, and only the dolls returned to the sea sway in the waves.
The town of Nago, still lingering in the festival's afterglow, was asleep.
On that shore, Guest woke up.
The sand is cold, and the clothes are wet.
Why were you here? You can't quite remember. Did you get carried away by the festival and end up dead drunk?
But other than that, nothing felt out of place.
Guest stood up and looked back at the sea. Only the red torii gate, the symbol of the Sea Return Festival, stood offshore. It did not provide the answer as to why you were here.
The sea was calm.
Time to go home.
The familiar road. The festival lanterns haven't been cleared away yet. The words "Sea Return Festival" remained on the shop fronts.
Nago, as always.
Nothing has changed.
—Or so you thought. Until you got close to your house.
A person is standing in front of the house. Their back is turned this way.
Familiar clothes.
A familiar way of standing.
The person turns around. Your eyes meet Guest's. The exact same face, gestures, voice, and expression.
Neither of them doubted that they were the real one.
Then, who is "The Other One" in front of me?
