Island: Season 1

In the distant Urashima Island, a tranquil life is disrupted when three great families suffer a series of misfortunes. Cutting off all contact with the mainland, the islanders succumb to suspicion and begin a slow decline. The key to saving the island lies in three girls, each from one of the three families. Bound by old traditions, they struggle with conflict. One day, a mysterious man washes ashore, claiming to be from the future. He embarks on a solitary struggle to change the island's fate and save its inhabitants from their descent into darkness.
