Millefiore Famiglia (future)
The Cervello is an all-female organization that currently works for the Vongola Famiglia, but works for the Millefiore Famiglia in the future. They appear to consist of only women, although it is unknown whether this is true as they appeared to have men of other appearances fixing the school with illusions; however, it is not determined whether these men are disguised pink-haired Cervello. Byakuran has stated that the Cervello's 'speciality' is to judge fairly, and that they are never biased, even if they support one team over another.
Each time they appear, they appear in a pair with matching outfits. Each Cervello's clothes vary, but resemble the current Japanese trends. Every Cervello has the exact same mask on their eyes and long pink/lavender hair, although in different positions the hair lengths vary (such as during the Vongola Ring Conflict - Sky Match, only the judges have long hair while other Cervello who were in charge of taking care of unwell participants, such as Lambo, had shorter hair). The Cervello are masked women that act as judges in games or tournaments. Supposedly, the Cervello are loyal only to the Vongola Famiglia, but they work for the Millefiore Famiglia in the future. So far, they have made 3 appearances: judging during the Varia Arc, serving Shoichi Irie, and judging in Choice. Their roles include:
- Keeping the rules in place.
- Informing contestants of the rules.
- Serving someone with a higher position.
The Cervello were first introduced in this Arc, appearing right after Iemitsu says they're to await further instruction from the 9th. They explain about how they will judge the Ring Tournament and how the matches will be held at Namimori. They then disappear until the night of the Sun Ring Battle, throughout which they refuse Tsuna when he wants to give Ryohei a pair of sunglasses after the match has already begun. During the second match, the Lightning Ring Battle, they oversaw the battle until the very end, unblinkingly watching as Lambo was about to be murdered by Levi, and make no move. After Tsuna saves him, they disqualify both Lambo and Tsuna from the tournament and give both rings to the Varia side. Xanxus then attacked a Cervello because she attempted to stop him. The Cervello then announced the next Vongola Ring Tournaments: The Storm Ring Battle. At the Storm Ring Battle, they explained the rules and the terrain of the battlefield. It is also shown that the Cervello attacked by Xanxus before was replaced by another member of the Cervello which looked identical to the old one. In the end, they informed the contenders and audience about the time limit of the bomb, causing Gokudera to let go and thus, letting the Varia win. In Yamamoto's Rain Ring match, they once again explained the rules and the battlefield, explaining that the water cascading down from the top floor will make the water level rise and that when it reached a predetermined level it would release a ferocious beast. After the match, they also stated that 'as the person who was defeated, Squalo's survival was no longer their responsibility. The next match would be the Mist Ring Battle. The battlefield for the Mist Ring Battle was revealed to be the school gym. No obstacles were placed and each player could use anything in the room. However, they did install infrared triggers intended for the audience not the players. In the end, Chrome emerged as the winner and the Cervello announced the next game: the Cloud Ring Battle. During the Cloud Ring Battle, the Cervello once again explained the rules and the battlefield and the place where the audience will stand. After Hibari defeated the Gola Mosca, they were alarmed and even shocked at how fast the Gola Mosca was defeated. They also didn't intervene when Hibari and Xanxus started fighting each other. Even after Gola Mosca's restraining system was broken and the 9th Vongola boss was revealed to be inside, they failed to act and instead announced the next Ring battle: the Sky Ring Battle. For the Sky Ring Battle they explained that the entire school would be the battlefield and that they were to once again fight for the Rings. The Rings were then revealed to be on extremely tall posts which were in various locations. However, an unexpected twist occurred, where both contestants' guardians were injected with a poison from their wristband. The Cervello revealed that the "Death Heater" poison paralyzes the nervous system and causes pain in the victim, which intensifies over a 30 minute period, at the end of which the victim would be dead if the antidote is not administered. The antidote is automatically injected into the victim's body when you put the Vongola Ring into the wristband. When the true intentions of the Varia were revealed, the Cervello instantly disqualified all members of the Varia and attempted to allow the rest of Tsuna's Allies help Tsuna. However, the Varia had sabotaged the infrared boundary and it wouldn't deactivate. Yet, all of the Varia's 50 squads were defeated by Lancia. With this, the Sky Ring Battle concluded and Tsuna's team was declared the winner. Interestingly, when Xanxus is lying on the ground, and the Cervello approach him, he says that the fight had gone the way they wanted and asks if they are happy now. They reply that they were always neutral, but that everything had been decided beforehand. As Xanxus passes out, he remarks that they are "cunning foxes".
In the Future Arc, they served Shoichi Irie, obeying his orders, suggesting ideas, and accompanying him.
In the game of Choice, they acted as judges to prevent cheating and biased judging. It is also revealed that they are now a part of the Millefiore Famiglia. In the first round, they just addressed both teams as most of the rules and explanation had already been explained by Byakuran. The Cervello judges during this Choice Arc appeared to be using Sun Flames Boots to fly and watch the ensuing battle.
In a flashback, the Cervello are shown giving Byakuran his Sky Mare Ring, stating that there was no one more deserving of the Ring than him, despite Byakuran's warning of possible meddling in world domination and destruction.
