Danger and action abound after Akira Sengoku and his classmates crash-land 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?
This is about Akira Sengoku who is on a field trip with his fellow students and some of his teachers in South America. During the flight back to Japan something weird occurs, and everyone on the plane ends up on a prehistoric island full of thought to be extinct prehistoric animals. The kinds of species that the characters first encounter on the island are Diatryma, Hyracotherium, Ptilodus, Eumegamys, and Saber-Tooth Tiger.
