The cursed pact between a naive queen and a millennial demon will give birth to a child. The little one, helped by the Kami (spirit) of the Wind, will be adopted by a simple family, and will show a gift bearer of death and destruction whenever she is in danger.

Assassins sent to kill her, won over by her diabolical charm, will make her the heir of Ryūjinja, a monastery of spies and thieves. Here the girl will be called Akiko and develop the ability to see the Ōra, souls of living beings, and learn to use the spiked chain Sashimasu.

Akiko will be sent to a distant island to kill a prince, but nothing will go as planned. From that moment, the young woman will move through ancient myths, looking for an artifact to restore balance, in an epic fight that will decide the fate of the world.
