Before becoming Rimuru Tempest, the protagonist Satoru Mikami is killed and reincarnated as a slime in a fantasy world. With his new form he quickly discovers unique powers, such as Great Sage, and forms strong bonds with many monster tribes. Rimuru gathers allies, defeats threats, and builds the Jura Tempest Federation, a nation that welcomes all races. Across his journey, he evolves from a simple slime into a powerful, benevolent leader who seeks peace through diplomacy and strategic strength, shaping the fate of his world.
