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 not having one doesn't 
bother me at all, really.
لكن عدم امتلاك واحدة لا يزعجني إطلاقاً
Aber auch ohne geht
es mir doch ganz gut.
Pero no me molesta no tenerla.
Pero tampoco me preocupa
en exceso no tenerla.
Oh beh,
Bom, não é algo que me incomoda.
Впрочем, не то чтобы
меня это сильно беспокоило.
