Human life has begun.
After office worker Mikami Satoru was assassinated by a gangster on the road, he came back to his senses and found that he had been reincarnated in a different world.
However, he turned out to be a "slime"!
He started his life as a slime after getting the name Rimuru. As he interacted with various races, he set a goal - to "build a country where all races can live together happily"!
When he completed this goal, an accident happened. He, the former Mikami Satoru and now Rimuru, accidentally reincarnated in a different world.
"Hello everyone, I am Rimuru Tempest, and I am also Satoru Mikami. I am just a weak slime."
The boy with long light blue hair said this.
