|Famiglia Name||Giegue Famiglia|
|Allied Families||Vongola Famiglia|
The Giegue Famiglia (nicknamed the "Grave Diggers") is a three-member allied Mafia Famiglia to the Vongola Famiglia, consisting of two males and one female, that hails from Russia. They planned to attend Vongola Decimo's Inheritance Ceremony in Japan. They have a fearsome reputation as a group of assassins, as Gokudera was nervous about his own appearance when he heard the Giegue Famiglia was coming to the Inheritance Ceremony.
They first appear when they discovered the location of the group attempting to interfere with the Ceremony. As a result, the Giegue Famiglia decided to deal with the interfering group as a gift to Vongola Decimo; however, they were defeated by an unknown female fighter, who, according to them, did not possess any of the conventional Dying Will Flames. Though the actual outcome of their battle with the mysterious fighter has yet to be confirmed, Reborn stated that their bodies were left in strange positions, implying that there were no survivors of the conflict. During the Inheritance Ceremony, the attacker was revealed to be Adelheid Suzuki of the Simon Famiglia, who used a Glacier Flame, a Dying Will Flame belonging to the Dying Will Flames of the Earth rather than the Dying Will Flames of the Sky.
