The Casual Life of a Dimensional Guardian

Khun is a Dimensional Guardian. He had been a dimension for millions and even billions of years. At the present time, the war with the chaos creatures is finally over. With the end of the war, Khun's job as a Dimensional Guardian is automatically terminated since the current dimension does not pose a threat like chaos creatures. This is what causes Khun to want to experience the life of a normal human being in a normal world. How is the story going? Please follow.
