Following a catastrophic event, portions of earthquake-ravaged Japan have become overgrown with vegetation. In a world where governments control emissions, a stark division exists between the privileged and the impoverished. Seeking to construct a utopia to replace Tokyo, the Japanese government established "Project Atlas." However, due to spatial restrictions, some individuals will be relegated to living in jungles as refugees outside the city. Nevertheless, where flaws exist, there are those who are prepared to resist. This group consists of Kuniko Houjou - a successor of a rebellious settlement, Mikuni - a mystifying and potent child kept in a covert temple, Kunihito Kusanagi - a soldier of Atlas, an exclusive high-tech conglomerate, Karin Ishida - an economic genius entrenched in markets worldwide, and the treacherous Ryouko Naruse - the leader of Atlas and the dominant power in this future world. Can the rebels, known as "Metal-Age," come together to demonstrate that compassion and collaboration overcome cruel segregation?
