An ordinary high school student by day, an assassin living in the underworld by the night. A boy with two faces, Aragi Kai. His classmates hate him because of his anti-social character and weird aura. One day, Aragi and his classmates were suddenly transferred to another world. It is a world of swords and magic. A woman who calls herself Leonora appears before the confused students, and declares…
“You are Hero Candidates summoned here to defeat the Demon King. Please help us.” Leonora grants each of the students a unique ability: ‘Divine Protection’. While some powerful ‘Divine Protections’ are given like telekinesis and destructive blast, Aragi’s ‘Divine Protection’ is judgment.
