UTOPA

After centuries of environmental destruction, war, and the use of nuclear and biological weapons, Earth became uninhabitable, leading to the extinction of numerous species. In response, humans established an aerial city to protect and preserve life, where animals were genetically modified and eventually evolved to walk upright and develop language. Over time, they formed a peaceful civilization, forgetting the ruined world below. When children from the aero police discover a mysterious seed from the surface, they begin an adventure in the unknown terrestrial environment, unaware that descending to the ground means they cannot return.
