Rimuru is building a dungeon in preparation for the upcoming festival. It will feature treasure chests containing weapons made by Kurobe, and Veldora will inhabit the deepest floor as the final boss. Then Milim suddenly shows up with a suggestion...
Now he'll unleash his aura within 
the labyrinth without reservation.
والآن سيطلق عنان هالته داخل
المتاهة من دون تحفُّظات
Damit wird er ohne Zurückhaltung
im Dungeon seine Aura entfesseln.
Así liberará su aura
en el laberinto sin contenerse.
Así liberará su aura
en el laberinto sin contenerse.
Comme ça, il va déverser à fond
son énergie dans le donjon.
Sono sicuro che rilascerà la sua aura
all'interno del dungeon senza farsi scrupoli.
Agora ele liberará a aura
no labirinto sem se segurar.
Зато сможет теперь высвободить
всю свою ауру в подземелье.
