The Vindice suddenly appeared and defeated Team Skull in a matter of seconds on the second day of the Representative Battle of the Rainbow. Jager was in the lead with Bermuda riding on his shoulder. At the end of the second day of the Representative Battle, Bermuda announces that he will take part in the battle with his team.
3rd Day Representative Battle of the Rainbow
During the third day of the Representative Battle of the Rainbow, Bermuda and Jager observed the battle between their team against Team Reborn and Team Verde. He expressed his interest in Reborn, and after Jaque and his two teammates were defeated, he appeared in front of the both teams and offered Reborn to join his team. When Reborn refused, Bermuda forcefully take Reborn with him by sucking him into his warp hole. Unexpectedly though, Tsuna was also sucked into the warp hole when he tried to help Reborn.
At the Vindice Prison, Bermuda and Jager explained the secret behind the curse of the Arcobaleno and revealed their desires to take their revenge on Checker Face for what he had done and to honor the previous Arcobaleno by winning the Representative War, though this means sacrificing both the Vindice's and the current Arcobaleno's lives. Hearing this, Reborn rejected the offer and chose to follow Tsuna's will, amusing Bermuda. Jager and Tsuna engaged in combat with Jager gained the upper hand since the start. Before Jager could continue further, Bermuda stopped him. He explained that he only want to show Reborn that Tsuna has no chance to beat him so he would reconsider his offer to join him once again and will have his answer right once the next representative battle start. Before he left with Jager, he warned Reborn that whether he accept or refuse his invitation, he'll end up in hell.
4th Day Representative Battle of the Rainbow
Bermuda sensed the flames and presences of each Team in three different locations and orders his members to split into three group. He and Jager approaches Reborn and his team to hear his answer regarding his invitation, to which Reborn declined. Hearing Reborn's answer, Bermuda orders Jager to fight, allowing him to kill if necessary. Much to his and Jager's surprise, however, Reborn's representatives were all a puppet decoys created by Verde, Irie, and Spanner, but noticed that Reborn is real and realizes that the three teams has joined forces to defeat him and his team. Shortly after Alejandro's defeat, Bermuda assumes that Tsuna and his friends are using a cover that able to hide their presence and Dying Will Flames, and according to the report from Big Pino and Smorgia, Team Verde are also decoy puppets but after it were destroyed, illusions appear, fighting them to buy times until Tsuna, Enma, and Basil arrives to defeat them. Knowing the plan, Jager suggested to Bermuda for them to go to Big Pino's and Small Gia's place, but they suddenly senses group of flames and then Dino, Mukuro, Squalo, Xanxus, and Byakuran reveals themselves, preventing them from leaving.
Jager proceeds to seriously wound the entire group. He only appears to have trouble when Hibari arrives, seemingly unable to use the short warp for a brief period of time. The mystery is revealed with the arrival of Tsuna's group; Jager and the other Vindice have no flames of their own and are forced to draw their power directly from Bermuda. This is why Bermuda returns to Jager's shoulder frequently. With this revelation Bermuda is forced to withdraw as providing power violates the rules of the battle. Without Bermuda's power, Jager is overpowered by Tsuna. Frustrated by Tsuna's interference, Bermuda requests his present and changes to his true form.
