The Azure Shrine Maiden lived in the time before recorded history. She was the first Amanohokosaka Shrine Maiden that had the duty of guarding the Gate of Sheol in Wadatsumi. She had the unique power to communicate with the Azure and gained incredible knowledge from contacting it. One time she touched the Gate while speaking to the Azure, which caused the Gate to open and the Black Beast to emerge from the Boundary. In order to stop it from destroying the world the Azure Shrine Maiden lured the Black Beast back into the Boundary and sealed the gate, trapping both of them inside.
