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.
I was such a hot, 
manly man (self-proclaimed),
كنت رجلاً وسيماً بكل معنى الكلمة
(في نظر نفسه)
Ich war so ein Bild von einem Mann.
Klammer auf, selbsternannt, Klammer zu.
¡Era un tipo tan masculino
y ardiente (autoproclamado)
¡Con lo masculino y macizo
que yo era (autoproclamado)
J’étais si viril et beau garçon !
Ero un uomo (autoproclamatosi) figo e virile!
Eu era um gatão másculo
(auto-proclamado),
Я ж был горячим мужиком
(по-моему мнению)!
