Shion and the rest of the fallen are revived, Diablo has joined the team... It seems as if all is going smoothly, but Rimuru then receives a report that Milim has declared war and Eurazania has been destroyed, and there's still the matter of the Western Holy Church's hostility toward monsters, even with Falmuth out of the picture. But at the same time, Raphael informs him that the Appraisal of Unlimited Imprisonment has been completed. At last, two years after Rimuru's reincarnation into this world, he can finally fulfill the first promise he made here: to free Veldora.
So in the worst case, we could 
be up against three Demon Lords?
إذاً في أسوأ الحالات، قد نكون في مواجهة
ثلاثة أسياد شيطان؟
Wenn es ganz schlecht läuft,
müssen wir gegen drei Dämonenkönige ran.
En el peor caso, enfrentaremos
a tres Reyes Demonio.
En el peor caso, nos enfrentaremos
a tres Reyes Demonio.
Dans le pire des cas, j’aurais donc
trois rois-démons contre moi…
Quindi nella peggiore delle ipotesi, 
dovremo scontrarci con tre Re demoni.
Significa que, no pior dos casos,
terei que enfrentar três Lordes Demônios.
И в худшем случае… нам придётся 
выступить против трёх Князей сразу?
