Myriad Devils
In the year 2081, humanity has endured the aftermath of the apocalypse, but significant changes have unfolded. The remnants of humanity are now concentrated in six cities, the last bastions of civilization.
After being exiled from the city lord's manor, Anon, the son of the supreme commander, encounters a "devil" named Seth. Seth offers to satisfy Anon's thirst for knowledge and the immense power that accompanies it. In return, they plan, helped by the forces behind Seth, to assassinate Anon's father, the lord of humanity.
A treacherous journey, fraught with calamities and tribulations... Anon will unhesitatingly walk through this path, whether that be for his dead mother, or for his own selfish desires.
