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...
Sorry to make you wait, Veldora-kun.
آسف لجعلك تنتظر يا فيلدورا-كن
Sorry fürs Warten, Veldora.
Llegó el momento, Veldora.
Ha llegado el momento.
Ton supplice est fini, Veldra.
Scusa per l'attesa, Veldra.
Desculpe a demora, Veldora-kun.
Прости, что пришлось подождать.
