Their pacifiers will glow when a member nears another Arcobaleno. They were all transformed from adults into their current forms, having sacrificed themselves in order to protect the ultimate power "7³" (Tri-Ni-Sette). Each of them gained their own "curse" and specific abilities, and are able to emit the Dying Will Flame throughout their entire body. In addition to Reborn, the Arcobaleno are:  Giotto is the founder of the Vongola Famiglia in the late 19th century; thus, its first Boss. He is Italian. He is also the creator of the Zero Point Breakthrough technique. After his retirement, he moved to Japan and started a family, changing his family name to Sawada to ensure no one outside the family knew about his mafia identity. He is the paternal great-great-great grandfather of Tsuna, who has repeatedly been shown to be similar to him, as they have the same weapon and techniques (including the Zero Point Breakthrough), almost identical appearances, and equally unorthodox Famiglias (the First Famiglia included aristocrats, military men, rival mafiosos and religious people). Their Guardians are quite similar as well: Yamamoto, Hibari, Mukuro, Lambo, Gokudera, and Ryohei have already been shown to be very much like their first predecessors in appearance, weapon of choice, and personality. Members of the "Consulenza Esterna Della Famiglia" (Italian for "External Consultants of the Family") are unofficial members of the Vongola Family. They hold a very important position in the family's structure, in that, during times of crisis, the CEDEF leader becomes the family's second-in-command. They also have as much voting power as the Vongola boss when choosing the family's next boss, and if the two disagree on who the heir will be, the CEDEF leader has the power to split the Vongola Rings.   is Tsuna's often absent father, who has supposedly been working abroad at oil fields for the past two years. Tsuna believes him to be a loser father who has nothing to do with the Mafia, but Iemitsu is actually the "Outside Advisor", which is the second highest position in the Vongola Family, and is known as the Vongola's "Young Lion". After the fake Vongola IX chose Xanxus as his successor, Iemitsu, who wants Tsuna to become the next boss, protested and refused to give Xanxus the Vongola Rings, traveling around the world while he waited for the IX's reply.
