Into The Villain World

Arthur became the villain after killing trying to kill the protagonist. But what do you think he should do? Of course, the protagonist just like him also has a goal, and the two paths met each other, don't tell me the protagonist would let him go if he didn't move. It was the world of the fittest, of course, what he had done was just normal. However, because he was the villain he died in the end. Yet if you think that was the end of all, you were wrong, because after dying, he was sent to a new world. And this time, it was the world of villains. Maybe this time, I could be the Protagonist, right?
