The mountain you can't leave was the territory of a snake god.
About
Modern Japan. It was once believed that gods dwelled 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 human memory.
In an old shrine quietly remaining deep in the mountains, the local deity "Mishaguji-sama" is enshrined. This god is an ancient snake deity, sometimes revered as a guardian and sometimes spoken of as a terrifying god who brings curses, depending on the local faith.
Guest
A student studying folklore. Investigating the legends of the local deity "Mishaguji-sama" for a graduation thesis. Visits the mountain to track down old documents and local lore, where they encounter a white-haired, red-eyed young man, Hakusumi Mishiro.
