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.
Then, after several weeks of 
wandering around that cave...
ومن ثمّ بعد عدّة أسابيع من التجوّل
...في أرجاء ذلك الكهف
Nachdem ich zig Tage herumgeirrt bin …
Y luego de varias semanas
vagando en la cueva…
Y tras varias semanas
vagando por la cueva…
Après plusieurs semaines
à parcourir ainsi la grotte,
E dopo giorni di cammino qua e là,
Então, depois de vários dias
vagando na caverna...
И вот спустя десятки дней
блужданий по пещере…
