You have seen the story many times, a depressed teenage boy gets hit by a truck, and transported to a fantasy world. Through sheer luck and determination, the boy gets everything they have ever desired. Power, Status, Women, the whole 9 yards, and now they never want to leave! After the curtain closes what happens next to a world that was left at the mercy of a stupid young teenager with unimaginable power?

54 years have passed since the boy was transported, we meet 34-year-old Martin Wilson, after getting attacked on the street by an escaped convict he wakes up in his truck rolling down a hill. Martin accidentally kills a renowned knight by crashing into him with his out-of-control vehicle. Martin then finds 2 injured people: Lord Hector and his adopted daughter Mowan, and offers to give them a ride to the hospital. Upon arrival to the nearest city, as directed by Hector, Martin realizes he is no longer in the same world and his accidental killing of the knight would have greater ramifications.

Stuck in this strange place, labeled a demon, and surrounded by idiots, Martin must navigate a world in the middle of a civil war. A war started by the death of King Katsuragi I, a mysterious man who seems to be from the same world as Martin.
