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?
Miina has been swallowed whole, but Yarai has a plan that just may save her and subdue the beastly Chimera that has brought chaos to Sengoku’s camp. However, as good as Yarai’s plan is, it may not be enough to deal with a new, surprising element that comes into the mix. With some ingenuity and a bit of luck, Sengoku and his crew have come this far, taking on all types of monsters on this mysteryfilled island, but there still may be one beast that is more fearsome than anything they’ve ever seen before—something closer to them than expected.
