Seeing Gon's expression, Killua laughed and says it was the first time for him to see such expression. He told Gon that he came from a famous Assassin Family and he ran by stabbing his mother and his brother. After the conversation, Netero came and ask them both to join him on a little game while he was bored.

On their arrival, Killua and Gon are above the Trick Tower and figure out a secret behind the floor. Killua, Gon, Leorio, and Kurapika went down along with Tonpa. All of them are tested with prisoners of the tower and must win in order to proceed. After Tonpa, Kurapika, Gon, and Leorio manage to finish each of their games, Killua step in against Johness, a famous murderer who's sadistic and careless person. Both of them are going on a Death Match. Killua, who's easily defeat Johness by using his claw to rip his heart off of Johness, manage to win the game, giving him and the group a permission to proceed.
Killua, Gon, and his friends are waited inside a room for 50 hours and spend his time with Gon. After 50 hours has been passed, Killua and his friends moved on through many traps and trials.

While the hard one allow the five of them to go but it has a long way. Tonpa and Leorio, like before having a fight each other. Gon then came up with an idea to choose the hard way and breakthrough the side wall to sneak into the easy path, allowing all five of them to proceed.

Killua's target was Umori and he's been stalked by Imori but noticed him all along. When Amori and Umori arrived, they surround Killua together, confidently knowing they'll win. But in a blink of an eye, Killua vanished as wind and jump behind Amori, trying to find his target. Knowing that it was wrong, he knows that it was Umori's Plate that Killua looking for. After received the plate number, he threw away the other two unnecessary plate away, causing the three brothers lost their plates.
On the Last Exam, Netero held a one on one tournament where all candidates have each two chances in the fight. Killua, who's about to go on a fight with Pokkle forfeit the match, confidently thought he could win his next match. Bodoro, who was supposed to fight Leorio in the next round has given times to rest since he still injured after his fight with Hisoka. And so Gittarackur and Killua fight ahead, a match where Killua made his biggest miscalculation. Gittarackur then hold Killua and took his needles off, revealing his true form and he was nothing more than Killua's big brother, Illumi.
Illumi greets Killua and told him that he heard Killua stab their Mother and Milluki. He told Killua that it was all just a coincidence that the two meet on the Exam cause Illumi trying to get a Hunter Licence for his next job and was surprised that he met Killua here on the Exam. Killua told Illumi that there's no particular reasons for him to be a Hunter, since he was just felt like taking the Exam. Illumi told Killua that he's just a puppet who live in a darkness who can only feel pleasure when someone else is die.
Killua told Illumi that there really is something he want and that is to become friends with Gon and live a normal life because he's sick of killing people. Illumi told Killua that its impossible since he think that Killua needs no friends nor allowed to make one or more. Leorio got angered by Illumi's behavior to his little brother and told Killua to just kill him and told Killua that its useless for Killua to wish become friends with Gon since they already are friends. Leorio ensure Killua that Gon must've felt the same way. Illumi, who can't accept this decided to find where Gon is and kill him.
Killua got shocked and unable to move nor say a word. Leorio, Kurapika, and Hanzo decided to stop Illumi. Illumi thinking about a good way to pass the exam and then he comes back to Killua and forcing him to forfeit the match by lying to Killua. Trembled with fear of his big brother, Killua decided to take his surrender and reduced to his own shell. Illumi told Killua that he was just joking about killing Gon in a playful manner, however, Illumi told Killua that he needs no friend, nor he has the right to make one.
The next match is Bodoro VS Leorio. Killua, who's being selfless suddenly appeared behind Bodoro and stab him with a powerful thrust with his claws, resulting Leorio the winner and Killua immediately banned. He then left the place and went home.

Silva ask Killua if he want to see his friends which later Killua answered yes, with one promise from his father to never betray them no matter what and Killua agreed and leave, despite his mother's decision.
Killua was told by Gotoh to wait in the butler's office while Gotoh testing his friends in his way to see whether or not they're capable to take Killua. After a while, Killua came to where Gon, Kurapika, and Leorio are waiting for his arrival and the four reunite and leave the Zoldyck estate.
