Biography
Kayo was once the assistant of the fortune-teller Astrid. He was the only one who knew how to open Astrid's back room in her basement. Link finds a book in his house, which reads, "If you're reading my words, I have fallen to fate. Look to the east to pick up my torch." Upon finding the remains of Kayo on the easternmost point of the island, his ghost appears and informs Link how to open the room. After freeing Astrid, Kayo asks Link to continue to look after her. Later in the game, upon returning to the island, Link finds Kayo has been properly buried. His spirit stays on the island, however, and helps Link find two treasure maps.

The exact cause of Kayo's death is unknown, though Astrid implies that the Ghost Ship was responsible. He seems to take his own death lightly; he is only concerned for Astrid's well-being.
