As the world was destroyed by the most hellish earth shakes, tornados, tsunamis and hurricanes, people had to go on with their lives. But people became more and more hungry and killed each other for food and sometimes for their human flesh. People formed gangs and it became unsafe. In order to live, people had to be afraid of you... And to do that... You had to be in a famous and powerful gang. As child, it was impossible to survive. Only the strongest childs had survived  this craziness had started. Airi was one of those childs and also the youngest. She was 13 when it started and has survived for 5 years without fighting much. She doesn't understand herself and only one gang knew the truth. The mightiest gang and the most feared one; "Jigoku"(Meaning: Hell)
They know special power that has been gifted to Airi, the power to control everything around her, to control every living thing and control it as she pleases. And the leader of 'Jigoku'  wants that power in order to be even more powerful then now. They post an message that the one who captures her, will be rewarded with being a member of the gang. Only what if the information about Airi lacks out and everyone wants her for themselves? Will Airi learn her power and how to control it? Would there be anyone willing to help her? Would the world return to normal ever again?
