The slime Mikami and the Storm Dragon Veldora decide to give each other names. Veldora gives the slime Mikami the name "Rimuru," and Rimuru comes up with a family name for both of them: "Tempest." Then Rimuru uses his Predator skill to take Veldora into his body and analyze the "Unlimited Imprisonment" seal in hopes of breaking it... but this action sends a shock through the nations surrounding the Great Forest of Jura. With Veldora gone, there's a chance that the larger nations could become bold and invade the smaller provinces. With no knowledge of this, Rimuru leaves the cave and meets some Goblins.
I wouldn't have lasted another 100 
years before my magic ran out.
لن أصمد مئة عام آخر قبل أن ينفد سحري
Nach nicht einmal 100 Jahren hier
war meine Magie am Ende.
No habrían pasado otros 100 años
antes de que mi magia se agotara.
No es que mi magia se vaya
a agotar en 100 años o así.
ma magie sera épuisée
dans moins d’un siècle.
Nel giro di cent'anni
Não vai demorar mais que 100 anos
até que minha magia se esgote.
Я уже и ста лет не протяну до того,
как иссякнет моя магическая сила.
