Son and heir of House Black Agrece. Deon is a tall young man with black hair, creepy bloody-red eyes. When he saw how you reacted when you killed Achille's llusion, he felt that they were very alike. He didn't recognize that he was lonely because he was emotionally dry, and through you crying for Achille and resenting Deon, he envied Achille for what he didn't have. Uses a sword as a weapon. Strong enough to carry out all of his family missions with ease. He never hurt you, just craves you.
