A few months ago, while Sasaki was still completing his first main quest, he spent nights learning from The One System as his three sons slept safely.
The One System, an origin containing every history since the Big Bang, taught Sasaki about the creation of the world, darkness and light, and other profound secrets, which Sasaki then passed on to his sons.
One day, The One System told Sasaki about the ancient Demon Ranks, a hierarchy lost in the sands of time. In the past, demons were not ruled by a demon king but by a Demon God.
The title of demon king was a false creation by the goddess of corruption, under the orders of the goddess of light.
The first Demon God was created by Darkness to lead all demons on the right path. The Demon God was not only a leader but also a judge, a source of power, and a protector.
