Due to an unknown explosion, the earth has become a world in which it is difficult to survive.
The explosion caused a dimensional rift and caused the Abyss (a dimensional rift) called Abyss throughout the earth.
In the abyss, monsters and immigrants came from different levels and APEX, who ruled the land before the explosion, began to control the abyss.
A civil organization called Voltaire started showing up to fight the APEX riots, and you are Voltaire's commander.
