A young girl named Tomoko visits the Hiroshima Peace Memorial. There she has a mysterious meeting with Sadako, the little girl who was 2 years old when the U.S. dropped the bomb on her city during WWII and 11 when she died from the effects of radiation poisoning. Sadako takes Tomoko on an eye-opening journey.

In the future, mankind can no longer live on the ground due to intense radiation, both from the sun and from an abandoned nuclear plant. One day, a group of special police raided a religious cult compound, and after a fierce firefight two policemen found a winged mutant girl, with chains on her arms, barely alive. However, government scientists dressed in hazardous material suits immediately intervened and brought her back to a research facility. Realizing they were merely transferring her from one prison to another, those two policemen formulated a daring plan to set her free once and for all.

In 19th century France, a struggling single mother, Fantine, leaves her three-year-old daughter Cosette in the care of her new acquaintances, the Thernadiers.

Still, she endures the torment in the hopes of seeing her mother once again. One night, while doing errands for her host family, Cosette is assisted by an honorable stranger named Jean Valjean. After a brief conversation with the young girl, Jean acknowledges her as the type of person he has been seeking and rescues her from the clutches of the Thernadiers. They make their way to a nearby town where Cosette enjoys a new life thanks to her savior. Under Jean's guidance, Cosette promises to help others with her newfound freedom. She pledges to heal the nation, ensuring that no one else suffers her fate.
