Great Demon Lord

The, or Beelzebub III, is a very random and forgetful king. He wants to Destroy humanity but forgets that he already sent his youngest son to do that and after he is reminded that he sends his 1st son En to do the job with his little brother

Personality
He talks somewhat like the stereotypical teenager. He seems to randomly switch between a comedically menacing tyrant and a cheerful person, a trait other demons have said is "kinda annoying".
