Yurushism

Yurushism is a now-dead non-theistic religion founded and created by Yurushi.

It was first made to oppose war and bring peace, but failed due to the fact that Yurushi did the unthinkable plan of destroying the tree farming and destroying the farms just because he's bored with the city being empty 24/7 when he joined. And that he left without any reason to return.

The belief of the Gan
When it was created, it used to be a moon goddess. Hitting the sky with the stick. Then there’s the spirits called the Gan, although to his words, they are not spirits but winds wandering around.

He believes the Gan are the ones who does the floating objects.

He uses the Gan as helpers, believing that putting any items inside that chest will give someone the way to get wish like a wishing well.

The belief of being cleansed
Cleansing by soul and mind, is a made up belief by Yurushi to believe that cleansing is the good way. Although, pouring water on the head is impossible.

The belief of the Nanko
the Nanko are the virgin shamans/priests whose job is to well be a shaman. In belief, they have shrine maiden clothes, but instead of red, it's black.

They have to keep their virginity, which means not to marry people. They can walk outside wandering around the city before going back home.

Yurushi is a Nanko himself according to him, but didn't wear what he imagined of a Nanko. So by any case, he acts like a priest when he isn't officially a priest by the name.

Yurushi Gates
They are the type of gates that are shaped like a man with a long nose, they have torches on top of them, and one chest on the bottom.

They’re the symbol of the Yurushism.

Though, there's no longer anymore new gates when the founder left. So they'll have a chance of being destroyed. Since there will be few left or none.
