When the animal plague began, the entire population came together and built a solid concrete wall 50 feet high and 30 feet thick. This kept every single animal out of the human world. On the top of the entire wall there is an electrified fence and invincible, laser hurling Genghis Borgs mounted every 90 yards. Behind this wall the population that survived has been living for more than 30 years. Many things have come about since space is limited. The government created a law that forbade people to have children. The Northern Hemisphere is where the population has gone to survive with all the other people in the world. Outside of "The Wall" the majority of the population has been made to believe that it is covered in a yellow poisonous dust that was used to kill all living things, because of the plague.

However, despite Mal Gorman's scheme towards Ellie's special ability. After reaching the Inner District of the Golden Barrier, Ellie became furious after an enemy Pod Fighter Forces chasing her, causing her to crash into the Mist Rivers of the Shadow.

He uses his memories of Ellie and discovers that the government has been hiding Ellie alive.
Many weeks later, the government introduced the Fit Campaign for Shadow Children to set standards for their long term health. However, Mika refuses to cooperate with the Fit Mix Campaign which leads him into trouble with the Nurse and his Principal Mr. Gray. Disgusted by his behavior, Mr. Gray gave him detention, suspended him, and gave him a shock collar to wear as punishment.
