Kikyo Zoldyck  

, キキョウ＝ゾルディック

The mother of Killua, who sustained injuries while trying to stop him from escaping home, despite Illumi expressing pride in his actions. She dresses in Victorian attire and wears a visor over her eyes. As the matriarch of the Zoldyck family, she is also an assassin herself. Although cautious, she seems slightly paranoid about Killua's friends Gon, Kurapika, and Leorio. Kikyo eagerly anticipates Killua's mastery in assassination and his continued contribution to the family business.
