Longchamp Naito, the Tomaso Family's boss, ends up in the same class as Tsuna during their second year, and thus tries to become friends with Tsuna, even inviting him to his house and to group dates. Later, when Tsuna and his family go on a trip to a Mafia island resort, he meets Arcobaleno Colonnello, who is, along with his rival Reborn, one of the seven strongest infants in the world. He also meets the Arcobaleno Skull, who starts attacking the island. Several Mafia families on the island unite under an unwilling Tsuna in order to defeat Skull and his crew, but Reborn and Colonnello end up as the ones who defeat Skull, ending the battle. Days later, when Bianchi holds a wedding ceremony in order to marry Reborn, the latter does not show up, causing her to go berserk and attack all the wedding guests.
