A feast is thrown to celebrate the revival of Tempest's fallen and the return of Veldora. After enjoying a brief, peaceful respite, Rimuru tells everyone his future plans: he's going to get the word out to the whole world that he's a Demon Lord and declare war against Clayman. Then King Gazel of the Armed Nation of Dwargon, Fuze of the Kingdom of Blumund, and Eren's father, Archduke Elalude of the Sorcerous Dynasty of Thalion, all arrive in Tempest, and an important meeting to discuss the nation's future begins.
That evening progressed into a party 
wild enough to be likened to a festival.
تطوّرت تلك الأمسية إلى حفلة جامحة
بما يكفي ليتمّ تشبيهها بمهرجان
In dieser Nacht ließen wir es richtig krachen.
Wie auf einem Volksfest!
Esa noche celebramos
una especie de festival.
Esa noche celebramos
una especie de festival.
Cette nuit-là,
la fête fut particulièrement endiablée.
Quella notte
А затем весь город погрузился
в атмосферу праздника и веселья.
