In July 2008 AD, due to the excessive advancement of science, a powerful super-magnetic weapon was deployed in war. The Earth's axis tilted, the crust underwent massive shifts, the five continents fractured, and landmasses sank—destroying half the planet in an instant! Twenty years later, on a surviving island, a boy named Conan, who had long believed that only he and his grandfather remained in the world after the catastrophe, accidentally rescues a girl named Lana on the island's beach. Lana possesses the ability to communicate with animals. Because her grandfather is a scientist, ambitious villains seek to capture Lana to use her as leverage. The intruders who arrive on the island kill Conan's grandfather and abduct Lana, prompting Conan to embark on a journey to rescue her.
