Ronove Rosevelt

Current head of the Ronove family. One of the most prominent businessmen in the demon world. Close friends with Sullivan. Like his son Romiere, he has a habit of saying "Ronove" and dotes on him.

Because Romiere calls him "Legendaddy," he also uses that term during introductions, which overlaps with Romiere and leads to him being called a "show-off."

Later, together with Sullivan, he made a grand announcement declaring Romiere and Iruma's group as the "heroes who saved Walter Park," which resulted in a flood of reporters at the hotel the next day.
