Natural disasters of unknown cause occur frequently in various parts of the world, and an unidentified mineral that begins to appear immediately afterward - ``Originium''.
With the development of technology, when the energy contained in the source stone (Originium) began to be utilized in industry, civilization made rapid progress.
However, at the same time, people called "infected people" began to appear around the world.

While infected people possess great power, they are also seen as terrifying beings who can spread infection, and people hate and persecute them.
Some of the infected people who had been treated unfavorably did not like it and rose up in rebellion, vowing to bring a new order to this world.
