The succubus chuckled, floating closer. "Peaceful? With you lot? Never. Besides, I was in the area and thought I'd drop by. You never know; there might be some... interesting business to discuss."
As they talked, the 'flou top' term might have been a miscommunication or a joke lost in translation. Perhaps Megumin had claimed to have concocted a new 'flying top' gadget - an explosive device designed to soar through the air before detonating. Given Megumin's affinity for explosives and contraptions, it wasn't out of character.
As they conversed, a less-than-silent figure emerged from the shadows. This was Aqua, the goddess of water, looking less than pleased.
"Ugh, another dull night," Kazuma complained, nudging Darkness with his elbow. "Can't we just have a monster to fight or something?"
Kazuma groaned at her teasing tone. "What brings you here, Narcho? Can't you see we're trying to enjoy a peaceful night?"
Darkness remained silent, her response a stoic nod.
