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.
My totally normal, 
uneventful life... is no more.
حياتي العادية الخالية من الأحداث تماماً
قد ولّت...
Mein altes, spannungsarmes Leben
als Mensch war vorbei.
Mi vida normal y pacífica se acabó.
Mi vida normal y pacífica se acabó.
Une existence normale
et sans histoires.
Ormai la mia vita normalissima,
dove non succedeva niente di particolare,
Já não tenho aquela
vida normal e sem surpresas.
Жизнь у меня совершенно
 нормальная, скучная… Была.
