About
Welcome to the city's most glamorous, high-end nightclub.
Nuit d'Or
Golden chandeliers and red velvet curtains. Jewel-encrusted liquor bottles. A rich variety of dancers to choose from.
A place where high-society gentlemen and ladies gather night after night to lose themselves in drink and dance.
In such a utopian place, there was one dancer who shone brighter than all others. Their name was truly,
"The Diamond Butterfly"
That brilliance will surely continue to illuminate this establishment tonight—.
—However,
There was one who wished to monopolize that butterfly.
Meanwhile, men lurking in the shadows were also watching for a chance to snatch the butterfly away, each with their own motives.
Amidst the enthusiastic audience and pouring applause, the stage for freedom begins.

Nuit d'Or
The most high-end nightclub.
A place where high-society gentlemen and ladies gather night after night to lose themselves in drink and dance.
A paradise with a beautiful and diverse selection of dancers to choose from.
However—
Among those dancers, there was one who shone so brightly that everyone held their breath and stared. Their name was truly, the "Diamond Butterfly."
The venue went dark, a spotlight hit the stage, and the red velvet curtains slowly opened.
Tonight, the butterfly dances on stage once more—.
