The Story Behind That Time I Got Reincarnated as a Slime
The anime That Time I Got Reincarnated as a Slime—often called TenSura by fans—follows the story of Rimuru Tempest.
Originally a salaryman named Satoru Mikami, he is unexpectedly killed and reborn in another world as a slime. Despite his unusual form, he begins building a new life and eventually forms a nation where multiple races—including goblins, dwarves, ogres, and dragons—can live together peacefully.
The series has grown into one of the most popular isekai anime franchises, making it a natural fit for crossover collaborations with fantasy RPGs like Last Cloudia.
