Ys follows Adol Christin, an adventurer driven by wanderlust towards the island of Esteria, who washes up on shore after a shipwreck. Following the guidance of the fortuneteller Sarah Tovah, he and his allies will travel the island in search of the legendary tomes known as the Books of Ys. It will be a long and perilous journey, but if fate is truly at work then Adol will certainly be the hero who returns peace to Esteria.—https://myanimelist.net/anime/1276/Ys
