Ordinary 37-year-old Satoru Mikami dies and is reincarnated as the most unremarkable creature imaginable—a slime. Initially, things are pretty grim. But by combining his special abilities with some good old-fashioned charisma, the newly named, Rimuru Tempest, will use his blobby powers to create a nation, destroy the malicious, and convince the world that maybe monsters aren’t so bad after all.
