On an apparently ordinary day, Youta Tada sees somebody peculiar entering the school grounds. All of a sudden this being shows up alongside him and influences him to tumble from the third floor! Yet, before he hits the ground, he awakens in a peculiar world where creatures like winged serpents exist! Youta at that point meets a youthful paladin named Lumi and finds that he is the main man on the whole planet, and furthermore that its occupants are to a great degree powerless to his essence or all the more particularly, his touch. Would this be a heaven?
