Ep 40. Nen x Users x Unite?

Gon, Killua, and Leorio are deeply concerned about Kurapika's safety, knowing that Hisoka is targeting members of the Phantom Troupe. As the group considers their next move, they come across a man named Melody, who reveals that she has the ability to hear the heartbeat of anyone in close proximity. With Melody's help, the group is able to track down Kurapika's location and rush to his aid.

Meanwhile, Kurapika is being held captive by Uvogin, a member of the Phantom Troupe, who mocks Kurapika's quest for revenge against the group. However, Kurapika manages to use his Nen abilities to conjure chains that restrain Uvogin, revealing that he has the ability to use Nen to control chains based on the condition that he can only use them against members of the Phantom Troupe.

As the group arrives to rescue Kurapika, they are confronted by Uvogin, but Kurapika steps forward to confront him alone. The two engage in a fierce battle, with Kurapika using his Nen chains to restrain Uvogin and deal heavy damage. With Kurapika's victory seemingly assured, Uvogin reveals his own Nen ability, which allows him to become almost impervious to damage.

As the battle rages on, the group realizes that they need to find a way to break Uvogin's impervious exterior. It is then that they remember a crucial piece of information about Nen - that it can be shared among users. With this knowledge in mind, Gon and Killua put their own Nen abilities to use, combining them to create a powerful attack that breaks through Uvogin's defenses and delivers a crushing blow.

In the aftermath of the battle, Kurapika is able to retrieve information regarding the whereabouts of the rest of the Phantom Troupe, but is left to ponder the cost of his newfound power and the challenges that lie ahead. The group leaves, bound by the bond they have forged through the harrowing experience they just endured.
