The Vongola Famiglia has long since been the most powerful Mafia Famiglia in all of Italy. Several other Famiglias serve under the Vongola umbrella, including several members of the infamous Arcobaleno. Even when there is internal strife, members of the Vongola stand united to repel attack from opposing Famiglia, living up to their title as the best and the strongest.
The Vongola came into being after Cozart Simon suggested to Giotto, the Vongola Primo, to create a vigilante group in order to protect the people. From then on, each generation of the Vongola Famiglia has donned formal attire when risking their lives to fulfill this duty. The Vongola originally started as a vigilante organization, but their ways gradually changed during Vongola Secondo's reign, starting to turn towards violence and crime.
