Danger and action abound after Akira Sengoku and his classmates crashland on a deserted island while flying home from a class trip. The island doesn't exist on any maps but that's not even the strangest part: the animals they find on the island are prehistoric beasts that are supposed to have been extinct for thousands of years! Now Akira and his friends are in danger as the island's residents start eyeing the humans for their next meal. Will they ever solve the mystery of the island and find their way home?
After days of exposing themselves to the danger of prehistoric beasts and the harsh climate, the survivors break into several smaller groups all trying to eke out an existence on the island. But when madness starts to effect some of the groups everyone could be in jeopardy! This volume of Cage of Eden includes special extras after the story!
