That Time I Got Reincarnated as a Slime Stagione 1 (2018)

The 37-year-old Japanese Satoru Mikami is rather content with his life. The only thing missing to complete his happiness would be a girlfriend. When he meets with a colleague and his new girlfriend, a thief on the run confronts them. Satoru protectively places himself in front of his colleague and is stabbed in the process. However, he suddenly hears a female computer voice and when he opens his eyes, he finds himself in a cave in the middle of a strange world—in the body of a slime!

Little by little, he discovers the benefits of living as a slime, like possessing the ability to dissolve other monsters within himself, in order to learn their abilities. During his exploration of the cave he happens to meet the powerful dragon Veldora, who has been sealed within this cave by an unknown hero. The two quickly become friends and Veldora awards him with a new name: Rimuru Tempest! As a result, a part of Veldora’s power is transferred to him and he absorbs Veldora with the promise of finding a way to free him from his seal. When Rimuru finally escapes the cave, he learns about the diversity of this new world in which he lives now. There are dwarfs, ogres, goblins, shadow wolves, and many more. Rimuru decides to establish his own village in which, little by little, many different and once hostile races come to live together peacefully. One day Rimuru meets Shizue Izawa who, as a child, was summoned by the demon king to this strange world. Rimuru has no idea yet that this meeting is going to have a significant impact on his fate.
