The most powerful Demon Lord in history, Varvatos, felt that he had accomplished everything he could as a king. Because he was so alone due to how powerful he was, he longed for a much simpler life. A few millennia later, he is reborn as the villager, Ard Meteor. But in the future where he was reborn, magical civilization had declined and magic itself had become weaker.
Ard enrolls into the Academy of Magic with his childhood friend Ireena and no matter how much he tries not to stand out, he can't hide the fact that he is not ordinary.
He is constantly surrounded by people awestruck by him, and many try to approach him. Meanwhile, the demons of the world who once struck fear into the hearts of the people have also gone into hiding...
Will the former Demon Lord be able to achieve the peaceful and mundane life he's always dreamed of? A heroic academy-life fantasy filled with chaos is about to begin!
