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.
If there's anything missing in my 
life right now, it's a girlfriend.
إن كان هناك ما هو ناقص في حياتي
الآن، فهو حبيبة
Wenn mir irgendetwas fehlt,
dann ist das wohl eine Frau an meiner Seite.
Si algo me falta en la vida,
sería una novia.
Si algo me falta en la vida,
eso es una novia.
Se proprio dovessi dire una cosa
che manca ora nella mia vita, direi una ragazza.
Se tem uma coisa faltando,
é uma namorada.
Если в жизни чего и не хватает,
так это девушки.
