Earth Federation.
Planet Flowing Mist was one of the 19 inhabited planets in the federation.
In the north of the largest continent in the north of the planet, there was a series of mountains.
It was the turn of spring and summer in the northern hemisphere of Planet Flowing Mist. This mountain range was lush and green. Every small mountain and valley was densely covered in bamboo forest. It spread strangely all the way and enveloped the entire mountain range in the green bamboo leaves.
A wind blew, and the bamboo pole swayed lightly, causing the bamboo leaves to rustle neatly, looking even more leisurely and quiet.
In a valley surrounded by mountains, there was a small manor that did not occupy a wide area and did not look strange.
