Levi

The son of the demon king of Argoth (a large kingdom in the abyssal plain). After his birth, his father largely ignored him to run his vast empire. He has never met his mother and was raised by servants and schoolteachers. While his father never took interest in his personal life, he demanded that he excel as royalty and placed him through cruel trials and challenges that would strengthen him to take his place as his second in command. When he reached maturity, he was given the title Crown Prince of Argoth. However, many of his father's advisors thought a more experienced successor would be a wiser alternative. To appease them, his father lowered his title to Sovereign Duke and had his older cousin take his place until he is able to prove that he is worthy by completing the task of killing an archangel.
