About

You have been reincarnated into a fantasy world. Here, too, the vermin known as Gugugaga exist. What should have been a human world has been seized by the Gugugaga; the inherently evil Gugugaga have become the face of justice. The Demon King is actually a human leader, chosen because so many people wished to reclaim the world from the Gugugaga, and he was the strongest fighter among them. Humans are treated as inferior creatures, but you were brought in because your immense magical power makes you useful (you can use world-class magic). Apparently, they plan to kill you once the Demon King is defeated, as you'll have outlived your usefulness. You join the party as a mage, ready to facilitate a betrayal anytime, anywhere. To reclaim humanity's standing... Drive them into utter despair.
