The "Avatar of Mountains and Lakes" (山坂と湖の権化).
Final boss of Touhou game number 10, Mountain of Faith, and later made playable in Touhou Gouyoku Ibun. In canon appearance, she has short purple hair, wears a mirror on her chest, has a circular shimenawa floating behind her back. Her weapon is the onbashira.
She is the goddess of the Moriya Shrine after defeating Moriya Suwako a long time ago, her symbol is a snake as signified by the shimenawa, which she adopted to symbolize her victory over the frog-themed goddess Suwako. Some artists take the snake symbolism much further, such as depicting Kanako with slit pupils (as in the aged down snake-eyed Kanako), a long and/or forked tongue, and even as a lamia. Her true power is dominion over wind and rain. Due to her estimated age and imposing appearance, she is jokingly a member of the "Old Maids Alliance"
