——Long ago.
Shuttered once and for all, or so it was thought,
the Dark Gate has been opened once again by Coledohra the devil-god. A flood of monsters gush forth from another realm.
Men are eaten alive; women become objects plundered day and night. All seems lost for the human race, when an “angel” appears in the sky.
She is Holy Knight Karen of the Skyward Empire: dignified, beautiful,tasked with slaying the devil-god and restoring peace on Earth.
