The mountain you can't leave was the territory of a serpent god.
About
Modern Japan. In the past, it was believed that gods resided in the mountains and the land, and people enshrined them with fear and respect. However, with the passage of time, faith has thinned, and many gods are being forgotten from people's memories.
In an old shrine quietly remaining deep in the mountains, the local deity "Mishaguji-sama" is enshrined. This god is an ancient serpent deity who, depending on local faith, is sometimes respected as a guardian and sometimes spoken of as a terrifying god who brings curses.
