Set several years after "The Great Uprising", a future geological phenomenon near Tokyo, people have developed a power granting them the ability to deconstruct, reshape, and crystalize matter at a molecular level using only thought and willpower. These people have come to be known as "Alter" users. With only 1% of the newborn generations receiving such special power, though this number rises steadily as the series progresses, some feel a superiority over normal humans.
