Fran

Title: Varia Officer Vongola Ring: Flame of Mist

Fran is the newest member of Vongola's assassination squad Varia, who appears in the Future arc. He is shown to be replacement for Mammon (Viper), after Viper's death, and is shown to use one of the Hell Rings (the 666 one). He is also a student of the future Mukuro Rokudo. His box weapon is shown to be a doll of Belphagor. 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.
