The Biochemical Attack of Counter-War

In this world, there are two organizations that are recognized as the strongest in the world. They are the defenders and the lurkers. The members of the Defenders and Lurkers are distributed all over the world. These two organizations are inherently hostile like fire and water, so the defenders and Lurkers can be seen fighting all over the world. In addition to these two organizations, there are many more organizations in the world, and it is not certain that there may be existences that can surpass these two organizations. Due to the struggle between these two organizations, a world-destroying disaster is quietly coming... This novel and its characters are purely fictitious.
