The Chronicles of the Shadow Sovereign: Rise of the True Demon Lord

In this alternate universe (AU) inspired by That Time I Got Reincarnated as a Slime, the fundamental lore of the anime is adapted to blend seamlessly with the ancient world of Macedon. The story includes powerful beings capable of shaping reality itself, and nations are built not only by the strength of their armies but also by the strength of their magic and alliances with otherworldly creatures.
