Everyone arrives at Mafia Land and Reborn explains about the security and investments of the place. After Longchamp and his men left, Reborn is asked by reporters for a press conference but he refuses and reveals to Tsuna that he is a celebrity there. The group then arrives at the beach and starts to go swimming. However, Tsuna is stopped by Reborn and ordered to go to the island's front desk and announce their arrival. Tsuna heads to the front desk where he is asked to demonstrate the correct way of bribing a government official since he doesn't have any invitation or letter of recommendation. He fails the test and is sent to the back of Mafia Land where Reborn accompanies him and where he meets another infant mafioso named Colonnello.
Tsuna sees that Reborn and Colonnello are rivals. Colonnello orders Tsuna to jump in a whirlpool. Tsuna refuses, causing both Reborn and Colonnello to punish him. As he is being beaten up by the two, Tsuna hears the voice of Gokudera and sees him waving at him from the other side of the fence. Colonnello and Reborn then kick Tsuna to the whirlpool and continue to beat him up. Just then, Longchamp arrives and informs the three that his girlfriend is actually a member of the Carcassa Famiglia who just arrived at the island and started a war led by another infant mafioso named Skull.
