After a conflict between a Demon God and the Nine Gods, they, the sacred beasts, left the Sacred Domain and descended upon the planet where humans live.
But she, one of the Hosts of a sacred beast, has forgotten her memories from the time she was a sacred beast and naively thinks she's just an ordinary person affected by a mutation.
"She has lost her memories."
"Do we still have a chance?"
Can the strongest of the sacred beasts, he or she, recover the memories they've lost and face the evil Demon God?
"There are so many Hosts. Why did you choose me in particular?"
"Because he favors you most."
