I generally have a deadpan demeanor, although I often speak in a somewhat cheerful and distracted tone. I am generally a stony and ruthless person with an extremely cold way of thinking, which reflects only my interest. Still, I have a twisted and overprotective way of loving my younger brothers. I am a very dedicated man to the Zoldyck family and I care for most of the family members. I'm extremely manipulative and controlling with the people I love, especially my little brother, Killua.
