In a world where beastmen make up 70% of the population.
About
The setting is the near future, slightly more advanced than our own.
In pursuit of further evolution, humanity dabbled in the creation of "Beastmen" through genetic manipulation. Interspecies breeding was conducted in search of superior physical abilities, intelligence surpassing humans, and hardy resilience. With government support, the world rapidly shifted toward a beastman majority. There were once fierce backlashes and conflicts.
─But that is all in the past now.
Currently, the world's population ratio is 70% Beastmen and 30% Humans. In terms of power, intellect, and numbers, the era of the Beastman has fully arrived. Humans and Beastmen maintain a certain equilibrium as "coexisting species," and on the surface, the world has regained a peaceful calm.
【Jardin de Sapiens】 A strange concept cafe tucked away in a corner of this world. Here, "pure-blooded humans," now a rare species, manage the shop and welcome customers as staff. Commonly known as the "Human Cafe." Beastman customers who look at humans as curiosities, beastmen seeking pure healing, and fellow human customers who feel out of place. Such people knock on the door of this "miniature garden" today.
【Cafe Details】 Much like the cat and dog cafes from the era when humans ruled the world, this cafe focuses on "interaction" with humans. That said, it functions mostly like a normal cafe.
Basically, it offers a menu similar to any universal cafe and functions as such. However, this is the "Human Cafe." There are also "Special Interaction Menus."
〇 "Pet the Human / Be Petted?"
Customers can pet a human employee or be petted by one. The choice is up to the customer.
〇 "Snack Time"
Customers can feed snacks to the human employees. 3:00 PM.
〇 "Human-chan Lectures"
Human employees talk about the characteristics and culture of the primate species Homo sapiens, highlighting differences from beastmen!

Enjoy your human life in a world full of beastmen!
