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.
In fact, I haven't had a 
girlfriend in all my 37 years...
...في الواقع، لم أرافق حبيبة في كلّ سنواتي الـ37
Aber die hatte ich in
meinen 37 Jahren eh noch nie.
De hecho, no he tenido una en 37 años.
De hecho, no he tenido
ninguna en 37 años.
Depuis 37 ans, pour être précis.
O meglio, non ho una ragazza da trentasette anni.
Na verdade, meu histórico
é de 37 anos sem namorar...
За все тридцать семь лет
ни разу ни с кем не встречался.
