Mikami Satoru, a businessman, is stabbed by a criminal on the street and killed. When he regains consciousness in the darkness, he finds that he's been reincarnated as a slime! With nothing better to do, he spends his time devouring all the rare herbs and precious ores he comes across. As he does, he encounters the Storm Dragon Veldora, who was sealed in this cave 300 years ago by a hero's "Unlimited Imprisonment" skill. He's frightened at first, but as they talk, he becomes friends with the long-isolated Veldora.
but survival of the fittest is the 
prevailing truth in this world.
لكن البقاء للأقوى هو الحقيقة
السائدة في هذا العالم
aber in dieser Welt gilt
das Prinzip des Stärkeren.
pero aquí solo sobrevive el más fuerte.
pero aquí solo sobrevive el más fuerte.
mais ici,
c’est la loi du plus fort.
ma in questo mondo prevale la legge del più forte.
mas a sobrevivência do mais forte
prevalece como a verdade neste mundo.
но в нашем мире могут выжить
лишь самые приспособленные.
