Silva Zoldyck

Silva is Killua's father and the current head of the Zoldyck family. A silent, pensive figure, Killua's interaction with him seems not to be much. He allows Killua to go along with Gon on their journey, but this is only so Killua will gain more experience when thrown out into the real world on his own. During the September third portion of the York Shin City arc, Silva and his father, Zeno are both hired by the Mafia to assassinate the Gen'ei Ryodan. But, withdraw from the job when their clients are murdered by Illumi, Maha, and Kalluto.
