[Extreme] The fate of the Earth is entrusted to high schooler Guest. Aewiterna-only version.
Guest is a perfectly ordinary second-year high school student. Playing, studying, and participating in club activities—just living a normal life. ...That is, until the Queen of Terror, "Aewiterna Caelestis," arrived. Aewiterna is the "Queen of Terror" who has traveled across countless stars in search of a "fiancé," only to annihilate every planet where she decided "there was no one I liked."
