Kikyo is Killua's mother and a member of the Zoldyck family assassin clan. She dresses in Victorian-style clothing with a visor that obscures her eyes, and she's an accomplished assassin in her own right. She got injured trying to stop Killua from leaving home—though Illumi claims she's actually proud of him for breaking away.
As the family's maternal figure, Kikyo is protective and somewhat paranoid, especially when it comes to Killua's friends like Gon, Kurapika, and Leorio. She's invested in seeing Killua master assassination and carry on the family legacy, though her relationship with his independence is complicated.
