Anime Futuristic Japanese Anime Post-Apocalyptic

22 years ago, a bizarre uprising occurred in Japan's Yokohama region, destroying civilization, killing many, and causing the area to break off from Japan's mainland. This region came to be known as the "Lost Ground". However, another phenomenon began to show up in the Lost Ground: Alter, the ability to rearrange matter at the atomic level in certain ways. "Inners" who were born with Alter powers became known as Alter Users, and Alter Users who lived outside the city and misused their powers were branded "Natives".
