This is a derivative work of Touhou "Mountain of Faith", so here's a brief summary for those unfamiliar. Once upon a time, three gods came to Gensokyo from a mountain in Suwa in the faithless modern world and founded a shrine. They are called the gods of Moriya.

Moriya Suwako A native god from the times of the Kojiki. Apparently really scary back then.

Kochiya Sanae A cheerful arahitogami who tagged along with the two goddesses. A direct descendant of Suwako or something like that.

Yasaka Kanako The goddess who defeated Suwako and conquered Suwa a long time ago. No screentime here.

Snake Husk Shedding one's skin is a symbol of rebirth and happiness. Might become a purse, might get enshrined. Sounds rough!
