The story opens with Juna telling her boyfriend Tokio that she feels too cramped in the city, and deciding to take a trip to the Sea of Japan. On the drive, they get in an accident caused by a large, invisible worm-like creature and Juna dies. As her spirit leaves her body, Juna sees the dying Earth. The planet's suffering is visualized by worm-like creatures similar to the one that caused the accident that killed her. Known as the Raaja, they vary in size, from microscopic bacteria to those entwining the planet. A young boy named Chris appears before Juna and offers to save her life if she will help the planet. She reluctantly agrees and is resurrected.
