Both Netero and Biscuit have mentioned that it’s a marvel Killua can even laugh and smile at all with how horrific his upbringing has been. It is shown that he intends to be a better version of himself after meeting Gon and being inspired by him. Despite his horrific childhood and cruel training, Killua has managed to maintain a generally optimistic attitude. He took a lot of risks to save his sister from the family household. The one whom he truly and unconditionally loves is his sister Alluka. In the end, he wants to be supported by his family. Despite the traumatic childhood, we do see Killua harboring feelings of respect and love for his father.
Killua is mostly very cold toward most of his family members, which is apparent from the incident in which he stabbed his mother and beat his brother to escape from the household. As a result, he has been put through harsh training since childhood. Due to his genius capabilities, he was deemed to be the future head of the family business. Killua apologizes to Nanika, admitting that he was still afraid of Illumi and swearing to protect Alluka.Our beloved hunter is a descendent of a legendry family of assassins, the Zoldyck family. However, when her sister wakes up, she becomes furious with Killua and understands that Nanika is a part of her. When he demands it again more forcefully, Nanika, crying, retreats into Aluka. Later on, Killua tells Nanika not to come out again, but Nanika couldn't understand what he meant. Gon is successfully recovered, although Killua does not tell him he was the one to save him. Killua responds they will always be together from now on.Īlluka goes into her wish-granting mode to heal Gon, and Killua asks Nanika to restore Gon to normal. Alluka expresses disappointment in turning into Nanika again and complains that she never spends time with him. After she awakens, Killua tells her that his friend is sick and wants to make him feel better. When they reach Gon's room, Killua waits for Alluka to wake up, under the careful watch of Tsubone and Amane. After a few light-combat between the escorts and his brother Illumi, he successfully arrives at the hospital to Heal Gon. Later on, Killua realizes that the escort team is controlled by his brother, Illumi Zoldyck, and tries to flee. When his dad Silva rejected his proposal to meet his sister, he declares that letting his friend die is the same as betraying him, reminding his father of the promise they made.Īfter leaving the house with his sister, Alluka Zoldyck, Killua calls Knuckle, confidently stating he can heal Gon but may need help to return to the hospital. Killua returns home to seek help from his younger sibling Alluka, whose ability would save Gon from death. Sick of killing, at the age of 11, he rebelled against his family, injuring his mother and older brother, and ran away from home to take the Hunter Exam for fun.
She thanked him for the thought, but she declined his offer to be friends due to their different status.Īt an unknown point in his life, his family determined he lacked the mindset of a real assassin and had Illumi implant a special needle in his head to remodel his character through fear subliminally. Around the age of nine, he met and attempted to befriend the newly hired Canary (an apprentice butler of the Zoldyck Family). When he was six or seven, he mastered the game of darts as part of basic training. At the age of three, he started training in tailing that routinely put his life at risk.
He had already mastered many killing techniques at a tender age and was set to be one of the best assassins the family had ever produced. Showing great promise from birth, Killua followed the traditional Zoldyck training, being an assassin. Killua was born as the middle child of a family of known assassins, the Zoldycks.
