Kashino Yukiko, who lives in a certain region of Japan, is nicknamed『Wild JK』by her friends.

Her grandfather, a hunter who has since passed away, taught her many things, and she would go into the mountains every day to trap, fish, gather, and dissect animals.

She suddenly wanders into the forest of another world, but using her natural toughness and her mysterious abilities, she makes it to the royal capital of Sampeluk, where she runs a popular bar called『Nihon』with a girl she met there, Lara, whose hometown was destroyed by a demon monkey.

The number of unique people increased one after another.
