About this game
A visual novel about what happens when a modern-day empress meets an ordinary man.
Marie Mamiya
VA: Shino Nakano
A modern-day empress who reigns on high as the head of the Mamiya Group.
As a young widow, her exceptional talent and sharp insights shot her to the top of the business world like none before her, and she has ruled over it with an iron grip ever since.
Though technically getting on in her years, she maintains an eerily youthful appearance.
Maki Suzuka
VA: Ria Akai
Like the protagonist, Maki shows up at Royal Family to pursue her dream of becoming a fitness instructor. Young, starry-eyed, and friendly to a fault, she hits it off with Yukio at once.
Much to her delight, she’s hired on the spot, too... but is it really what she signed up for?
From the moment she appeared at the Royal Family Fitness Club, an ultra-luxurious gym jointly run by the Mamiya Zaibatsu and Sugimoto Pharmaceuticals, she was instantly in charge. The first thing she did was appoint her own personal trainer, passing over a building full of muscle-bound men in favor of our unimpressive protagonist.
But she'll train him into shape—in the pursuit of beauty.
