A heavenly demon fights back against the hellish hordes of the Demon King, for one purpose - to protect. For life to prosper as it should. Not for it to be wasted on war and wanton slaughter. So, with the help of a party of Heroes, the heavenly demon fought the Demon King...and won. But with this great task finished, the Goddess of that world asked him to complete another: To spread peace. Not through war or conquering but through teaching. The great Goddess Venus wanted the heavenly demon to journey into the myriad worlds and teach others his brand of peace. His brand of...excellence. So, ever-faithful to Venus, the heavenly demon stepped through a portal and found himself in a peculiar world a teacher of something called...a highschool? He wanted to question the new information in his mind but first he had to deal with the robed people kneeling to him.
