転生したらスライムだった件 第4期

Killed on Earth and reborn in a fantasy world as a lowly slime, Rimuru Tempest turns out to be anything but weak, absorbing powers, befriending monsters, and building the outcast races into the thriving nation of Tempest. As his young country wins recognition, rival powers and old threats keep pressing on its borders. This second half of the fourth season carries the nation-building saga onward. Based on Fuse's light novels.
