Tensei shitara Slime Datta Ken

Office worker Satoru Mikami dies in Tokyo and awakens in another world as a small slime. His new body looks harmless, but it can consume objects, analyze them, and copy useful abilities. Deep inside a cave he meets Veldora, the Storm Dragon imprisoned for centuries, and their unlikely friendship gives Satoru a new name: Rimuru Tempest. After leaving the cave, Rimuru begins helping goblins and other monsters he encounters, and every alliance makes his growing community larger. What starts as a strange second life gradually becomes an attempt to build a place where humans and monsters are not judged by what they were born as.
