Dino (ディーノ, Dīno?) is voiced by Kenta Kamakiri and Kenn (34 episode). He is the 22-year-old 10th Boss of the Cavallone Mafia Famiglia (キャバッロネファミリー, Kyabarrone Famirī?), which is the number three Family in its Mafia alliance with the Vongola Family and is one of the largest families with 5,000 members. Dino is a young man with great leadership skills, along with great combat skills. He was born on February 4 in Italy with a blood type of O. His main Weapons are a bullwhip and his pet turtle, Enzo. Like Tsuna, Dino, at first did not want anything to do with the Mafia and was also a klutz. He became a suitable Mafia Boss after Reborn became his home tutor. He came to be known as "Bucking-Horse Dino" (跳ね馬ディーノ, Haneuma Dīno?) ("Bronco Dino" in Viz's translation) and fixed the Cavallone's financial problems, turning them into the third most influential Family. Unfortunately, Dino is so devoted to his Family, that when none of his Family Members are around, his skills decrease dramatically, and he will often accidentally hit people with his Whip and fall down the stairs.
Dino becomes Hibari's home tutor in order to train the latter for the Ring Battle. Thus, Dino travels with Hibari around the country in order to train him in various environments, with his right-hand man Romario, probably because he will mess up without his presence. However, he does have a little difficulty in training Hibari as all Hibari wants is to 'bite him to death'. He sees Hibari as being quite strong for his age, which is the reason why he is needed for Tsuna's family.
Training IIDino first appears at the end of Episode 157 on the school's rooftop, and meets with Hibari. He then later appears the downtime before the game of Choice, right after Basil and Yamamoto managed to quell Tsuna's raging Vongola Box Weapon. Dino says that Tsuna released it improperly, and if he does it again, he'll break it for good.
Dino assigns everyone to new tutors for the time being. Ryohei and Lambo under Gokudera, and Chrome under Bianchi with I-Pin helping out. He tells Tsuna that he'll have to practice on his own, and Yamamoto the same because if he teaches him anything wrong, "that guy" will kill him.
Dino reappears during the selection of the teams, right when Hibari says that he doesn't care about the rules. He tells them that he snuck in right when they were being transported to the Lightning Field. Dino manages to convince him that he should wait to attack, because after the battle, he can fight anyone he so chooses.
After the battle as a result to Uni's sudden appearance, Dino suggests to Tsuna to reorganize themselves as he observes that Byakuran will make the battle last long. As Byakuran catches up to them, Dino volunteers to stay and buy some time for the whole Vongola family to escape. He also seems to have information as to Mukuro's whereabouts since he commented that Mukuro will be helping him soon just before the real Mukuro appeared.
After Tsuna and his family returned to Namimori, Dino can be seen with Hibari running off to fight one of the Six Funeral Wreaths that landed at Namimori School. There they fight Daisy and defeat Daisy's Box Weapon, the Sun Rhino, with little difficulty. Daisy states that he was only going easy on them because he was happy that he found them, Daisy then reveals a box embedded in his body and activates it, changing his body into a weapon. Dino then releases his fully powered Sky Horse, with flaming wings that gives it an appearance of a Pegasus, which is then defeated by Daisy's left arm after the Sky Horse removed it. Dino then unleashes his ultimate technique, but to his surprise Daisy knows the technique, which Dino suspects from Byakuran's ability, and dodges it and incapacitates him, Hibari then comes to the rescue smashing Daisy through the school, and kicking Dino to Romario, stating that they need to stop going wild in the school. Dino then states how Hibari reminds him of the First Vongola Cloud Guardian and Hibari shows his Vongola Hedgehog's Cambio Forma.
