Okuni

A Great Wyrm and daughter of Amaterasu, the Sunlit Lantern, born just before the Wyrm's War.
Eventually, she came to reside at the edge of the known world (at the time), Yuhi, where she became entwined with the people there. She loved them and was loved by them, but eventually, she was slain by the calamity that drove the Yohi from their home. Depending on the version of the story, she was even the first victim.
