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 see you around a lot, but this 
is our first time speaking.
أراك كثيراً، لكن هذه أوّل مرة نتحادث فيها
Ich sehe Sie ab und an,
aber wir hatten noch nicht die Freude.
Lo veo mucho,
pero es la primera vez que hablamos.
Lo veo mucho,
pero es la primera vez que hablamos.
On se croise souvent,
mais on ne s’est jamais parlé.
Mi è capitato in più occasioni di vederla in giro, 
ma è la prima volta che le parlo.
Eu sempre o vejo, mas é
a primeira vez que conversamos, né?
Мы с вами часто пересекались,
но говорим впервые.
