The Millefiore Family, commonly known as Millefiore and Millefiore Famiglia [millefjore famiʎa], is the most powerful Mafia Famiglia in the world as depicted in the Future Arc, replacing the Vongola Famiglia.
The Millefiore Famiglia is the merging result of two powerful Mafia Famiglias in the future: the Gesso Famiglia led by Byakuran, and the Giglio Nero Famiglia, led by Yuni. Byakuran dulled Yuni's heart with a drug to make her agree to the merging of the Famiglias.
The goal of the Millefiore is to collect the Tri-ni-set, and use it to recreate all of existence. After the Future Arc has ended, their objective is to free Yuni of the short-lifespan curse of a Sky Arcobaleno.
The Millefiore Famiglia is organized into 17 different squads, each named after a plant or flower. Each group is labelled as either Black Spell or White Spell, to indicate their previous allegiance – Black Spell for Giglio Nero, and White Spell for Gesso.
Those originally from the Giglio Nero specialize in direct combat, while the Gesso specialize in cunning battle tactics. There is a general sense of hatred and distrust between members of the White Spell and the Black Spell, resulting in a lack of communication and sabotage by individual squads.

Six Funeral Wreaths
Six members, usually captains of a squad, are holders of Mare Rings. They are called the Six Funeral Wreaths, the most powerful group in the Famiglia, known only to Byakuran and its members, that performs duties similar to the Guardians of the Vongola Famiglia.
- Millefiore means "a thousand flowers" in Italian.
- Though Millefiore was dissolved after Future Yuni awoke from her drugged state, Team Yuni uses the Millefiore emblem on the chapter cover of teams who were participating.
