Holy Demonic Holiness

I possessed a great force capable of rivaling any existing hero, in fact I was once called the Great Hero, once by the inhabitants of this beautiful, wonderful and incredible world. Now I have returned as one of the 100 Demon Lords. Like the 99th Demon Lord Gremory... The weakest of all Demon Lords. In order to be able to live comfortably in this world, I will make everyone fall below my feet!
