One winter day, Selim succumbed to the Devil’s Temptation and transformed into a Demon. Before being killed by the Hero, he slaughtered the people of the Royal Capital and the nobles, and pulled the trigger for the devils to invade the Kingdom. After Selim’s death, the devils overthrew the Royal Capital and destroyed the Kingdom. Selim, who was trapped by the devil and watched the Kingdom fall, somehow found himself returning to his 14-year-old self. A message written on a transparent panel floats in front of him. "You have become a seeker. By doing the right things and accumulating virtues, your level will increase."
