That Time I Got Reincarnated as a Slime Season 4

Demon Lord Rimuru’s ambitious vision of forging a lasting alliance between humans and monsters is steadily approaching reality. As the thriving nation of Tempest continues to flourish under his leadership, new ideological threats emerge from unexpected quarters. Granville Rozzo and his granddaughter, Maribel Rozzo, challenge Rimuru with a fundamentally opposed philosophy. The Rozzo family believes that humanity can only be truly protected through absolute dominion over them, setting the stage for a tense and dangerous confrontation with the Demon Lord who champions coexistence instead. Beyond Tempest's borders, the political landscape grows increasingly complex. In the domain of El Dorado, Demon Lord Leon pursues his own enigmatic objectives, operating independently of the escalating conflict between Rimuru and the Rozzo faction. With powerful figures maneuvering toward their distinct ambitions, the balance of the world hangs in delicate suspense. Amidst this mounting tension, signs point toward a momentous event: the awakening of a new Hero draws ever closer, promising to reshape the unfolding struggle and alter the fate of all involved.
