What do you do when the world's most powerful hero sets his sight on world domination? The story started the same way so many others have. An introverted boy reincarnated in another world, granted overwhelming magical powers and sent on a quest to slay the Demon Lord. Only, things didn’t quite turn out as planned. They say that absolute power corrupts absolutely and once the Chosen One had saved the world he quickly declared himself the only one suitable to rule it. As the world falls under the shadow of a new tyrant, one angel decides to take matters into her own hands. She looks for another recently departed human that she can use to deal with the fallen hero and the job falls to Haneul Yun. A responsible young man just doing his best to be a proper adult when his life was cut short in a tragic accident. But she's not making the same mistake twice, so Haneul will be reincarnated without any special gifts or powers. Instead, he will have to rely on his own knowledge and cunning to find a way to liberate this fantasy world and assassinate the tyrant that was meant to be its hero.
