Hohzuki Island

Suzuhara Kokoro and his blind younger sister, Yume, are sent to live on a seemingly deserted island. A small group of children and their teachers are the island’s only other inhabitants. As Kokoro and Yume get to know the other children and observe their teachers, they begin to realize that the island is not what it appears to be. The siblings learn more about their strange surroundings through what the children tell them and what they witness the teachers doing.
