A thousand years ago, black mist shrouded the land, and darkness ravaged the world.
A Saintess saved the ruined world. To keep the continent of Kannode from falling into crisis again, before she disappeared she left behind a sacred relic that could give birth to her own avatars.
Time passed, and the crisis faded. It seemed that the great calamity existed only in history books. The word "Saintess" gradually became the title of an official position.
In modern times, a soul from Earth awoke inside an avatar of a Saintess.
She thought she could enjoy a leisurely life reserved for Saintesses, but an uproarious missing-person case in Li'an City shattered her peaceful existence.
