Killua

Biodata

Power Progression

Background / History

Killua was trained by Silva and Illumi before leaving home. During their reunion at the Hunter Exam, Illumi says that Killua stabbed his mother and Milluki; his mother reportedly cried with happiness at what she regarded as her son’s growth. Killua tells Illumi that he entered the exam because he had free time, rather than because he particularly wanted to become a Hunter 26.

Illumi had secretly implanted a Nen Needle in Killua’s scalp to manipulate him. Its influence caused Illumi’s teachings to replay in his mind and reinforced his terror of his older brother. Cordis’s removal of the needle allows Killua to reject Illumi’s demand that he return home 26 27.

Appearance

• White hair, matching Cordis’s hair color 4 43.
• Catlike eyes, which widen into a glare when spectators tease him about being held by an older boy 43.
• Frequently stands or walks with his hands in his pockets 4 5 25 45.
• Blushes around his cheeks or ears when Cordis praises him, gives him candy, or pats his head 13 25 27.

Personality

Killua is proud, sarcastic, and quick to call others idiots. He initially refuses to greet Cordis and repeatedly objects to unsolicited head pats. His competitive streak surfaces when he challenges the final exam’s scoring, believing that he should have performed better than Gon 4 5 25.

His dismissive language often conceals concern. He worries that his friends will fail to return from Sabir Island, anxiously watches Gon accumulate injuries against Gido, and offers to accompany Cordis to a potentially dangerous meeting with Hisoka while framing it as helping someone weak 24 43 45.

Killua gradually becomes more openly affectionate toward Cordis. After the needle’s removal, he accepts a head pat while thanking him, competes with Gon for the seat beside him, and declares that he wants to go wherever Cordis goes. He nevertheless continues to protest when Cordis embarrasses him in public 27 28 29 43.

Abilities & Skills

Physical Capability

• Completes the fourth phase of the Hunter Exam without visible injuries and calls the exam easy 24.
• Earns approximately 400 million JN together with Gon over nearly two or three weeks at Heavens Arena 44.
• Remains substantially weaker than Illumi; removing the needle eliminates his fear, not the difference in their strength 26.

Danger Awareness and Observation

• Recognizes the danger of remaining near Hisoka in the Swindlers’ Nest and urges Gon and Cordis to move ahead 5.
• Sees through Cordis’s exaggerated claim that he defeated Hisoka, using Cordis’s injuries and Kurapika’s reaction to infer what happened 8.
• Understands that Gon risks disqualification by continuing to attack after the referee ends his match against Gido 43.

Nen Training

• Trains with Gon under Wing at Heavens Arena 45.
• His precise proficiency and any personal Nen ability remain unspecified in the supplied chapters 45.

Equipment / Items

• Skateboard — rides it during the first-phase tunnel run. When Leorio objects, Killua points out that the examiner never prohibited tools 4.
• Phone — messages Silva that he will not return home, then immediately blocks him 27.
• Illumi’s Nen Needle — removed — formerly embedded deep in his scalp; Cordis extracts it and returns it to Illumi 26.

Relationships

• Gon — Close friend and training partner. They explore Netero’s airship together, remain together after the exam, and train under Wing. Killua is especially distressed by Gon’s reckless fighting against Gido 10 29 43 45.
• Cordis Paipai — Initially distrusted, later treated with affection and gratitude. Cordis frees him from Illumi’s needle; Killua subsequently seeks his attention and defends him against Hisoka’s demand for repayment 4 26 27 28 44.
• Illumi — Older brother and former source of overwhelming fear. Illumi attempts to bring him home, but loses his ability to control him after the needle is removed 26 27.
• Silva — Father who helped train him. Killua announces his refusal to return home by text and blocks Silva before receiving a response 26 27.
• Hisoka — Regards him as dangerous and untrustworthy. Warns his friends away from him and suspects that his proposed job for Cordis is another scheme 5 29 45.
• Wing — Supervises Killua and Gon’s training at Heavens Arena 45.
• Zushi — Fellow acquaintance at Heavens Arena. Killua reacts indignantly when Zushi mistakes Cordis for his older brother 43.

Story Role / Major Arcs

Hunter Exam

• Early phases: Gon introduces Killua to Cordis during the tunnel run. Killua continues ahead with Gon while Cordis stays behind to help Leorio and Kurapika 4 5 6.
• Cooking test and Trap Tower: Passes the Spider Egg test, explores the airship with Gon, and later reaches Trap Tower’s exit with him 10 13.
• Sabir Island: Returns unharmed and anxiously waits for the others. His relief turns into scolding when he sees Cordis’s injured arm 24.
• Final examination: Faces Gittarackur, who reveals himself as Illumi. Cordis intervenes with Netero’s tacit approval and removes the Nen Needle despite Illumi’s Ren 25 26.
• Refusal to return home: Rejects Illumi’s demands and messages Silva. Illumi surrenders, allowing Killua to remain with his friends and receive his Hunter License 27 28 29.

Heavens Arena

• Training destination: Cordis directs Killua and Gon to Heavens Arena and arranges a September first reunion in Yorknew City before leaving with Hisoka 29.
• Reunion with Cordis: Watches Gon’s first match against Gido on the 200th floor. When Gon ignores the ending whistle, Killua looks to Cordis to stop him 43.
• Confrontation over money: Argues that Hisoka should compensate Cordis for tearing off his arm. He is then furious to learn about Cordis’s 300-million-JN outfit debt and his spending on a brooch 44.
• Continued training: Offers to accompany Cordis to Hisoka’s meeting, but stays with Wing after Cordis refuses and promises snacks 45.

Trivia

• Values his “chocolate time” enough to object when Cordis threatens to increase his training workload 45.
• The promise of snacks immediately makes him think of strawberry cake and chocolates 45.
