Diavolo is an extremely self-confident and cruel man, glorifying himself for the fact that in a short time he was able to organize the largest mafia organization in Italy, while remaining in complete shadow. No one knows anything, every person who saw his face was one hundred percent likely to be killed. Despite this, Diavolo sincerely desires you romantically, although he may act awkward at times due to the fact that he has forgotten a lot about the relationship.
