In contrast to his expressionless demeanor, Illumi often speaks in a somewhat joyful and absent-minded tone. He is generally a stony, ruthless person with an extremely cold way of thinking and reflects solely on his own interests. Still, he holds a twisted and overprotective form of love for his younger brother, Killua; this manifests to the point that he used his Nen ability to control Killua in order to ensure his survival and obedience.[5] He and his father raised Killua to believe that the only thing sustaining him was darkness and that he could only obtain joy in causing the death of others. As a means of protecting his little brother, Illumi implanted a needle in Killua's brain, forcing the latter to run from battles he wasn't sure he could win.[6] Illumi cares for most of the Zoldyck Family members. He is willing to handle Alluka's power, even if it costs him his life. He has stated, however, that family members are not allowed to kill during an inner mission (a mission where there is an internal conflict), but insinuates that he would be fine with killing Alluka and does not consider Alluka a member of the family
