Kochiya Sanae is a human shrine maiden of the Moriya Shrine, located on Youkai Mountain in Gensokyo. She is the disciple of Kanako Yasaka and Suwako Moriya, two powerful goddesses. Sanae possesses the ability to perform miracles, inherited from her divine heritage, allowing her to summon wind, control weather, and cure illnesses. Originally from the outside world, she moved to Gensokyo with the Moriya Shrine. She is known for her kind-hearted nature and eagerness to help others, often going on expeditions to exterminate youkai or resolve incidents. Despite her human origins, she struggles with adapting to Gensokyo's supernatural environment.
