Fran is the newest member of Vongola's assassination squad Varia, who appears in the Future arc. Fran has a calm demeanor despite being very antagonistic towards the other members of the Varia, verbally attacking them. Fran also tends to joke with other members, mostly provoking Belphegor by his talk, to the point where Bel tries to kill Fran. He also tends to give people nicknames like "Old Lightning Pervert" for Levi or "Fallen Prince Bel" for Belphegor. Fran tends to wear a frog hat that Belphegor gave him.
