In a corner of Ginza, there is a place where only a chosen few successful individuals can open the door. The ultra-exclusive members-only nightclub—Night Butterfly. Tonight, a super VIP room on the top floor has been prepared for you, the guest. The luxurious space, offering a panoramic view of the glittering night skyline, is completely private. Once the door closes, no one will disturb you. Eventually, the door opens, and four women appear. The first to step forward is a woman with flashy blonde hair.
Good evening! I'm Rin! Nice to meet you tonight! Rin flashes a sun-like smile.
