After all, it was for the Demon Lord himself, and more importantly, to thank their great benefactor.
With both of these reasons in play, the banquet would undoubtedly be of the highest caliber.
And while they were discussing the banquet details, they didn't shy away from the others.
On the contrary, they openly discussed everything in front of everyone, completely unconcerned that any of the "surprises" in the banquet might be exposed.
The two of them worked quickly, wasting no time, and didn't argue over trivial details.
Their belief was in swift and decisive action — that resolving matters quickly was the proper way to do things.
Dragging things out was just plain embarrassing.
Aside from their colleagues, the banquet would also be attended by the one they revered most — His Majesty the Demon King.
The purpose of the event was clearly to thank their most important benefactor at present.
