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...
I'd like to get them in place 
before the festival.
أرغب في تجهيزهما قبل المهرجان
Wie bekommen wir das bis zum Fest hin?
Espero que estén
listos para el festival.
Espero que estén para el festival.
Tout doit être prêt pour le festival.
Sarebbe bello averli pronti per il festival...
E queria que ficassem prontas
antes do festival...
И то, и другое
нужно выстроить до праздника…
