I am Owen Pepper, the heir of a Noble family. To begin with, there are two kinds of people in this world. The aristocracy, winners from birth, and the rest of the losers, the cattle. I am a winner, of course. Bwahahaha. Livestock, you can work hard for me today. It is the only thing you lot are good for! I have been reincarnated as a trash aristocrat. My father was a villainous lord. And his son, Owen, has been deeply influenced by his father and has grown up to be a fat, incompetent boy! If this continues, my future is in jeopardy. … But I do not care about that! “I heard that there is magic in this world. If we are going to go to all this trouble, let us try to master magic!” And if you are having fun learning magic, you will soon be able to break the stigma! (Source: Novelupdates)
