Alluka Zoldyck

Alluka Zoldyck is the second youngest child of Silva and Kikyo Zoldyck. Under unknown circumstances, she was possessed by a mysterious Dark Continent creature, which her family named Nanika. The two currently share Alluka's body. Alluka has long black hair, blue eyes, and a pale complexion. She wears the traditional clothes of a Japanese shrine maiden, with boots and a headband adorned with emotional cartoon faces. Framing her face are two locks of hair, each fastened by four hair bands decorated with the same cartoon faces on her headband. As a younger child, Alluka wore pants with shoulder-length, unkempt hair. Before Alluka's formal introduction, Silva describes her as a dark and uncontrollable child. He claims that Alluka has no soul because of the circumstances of her birth and cannot feel emotions. However, once reunited with her closest brother Killua, Alluka displays an affectionate, simple, and lovable personality. Alluka is usually very happy around Killua and trusts him deeply, likely because he is the only one to show her compassion. According to Killua, Alluka calls him "big brother". In contrast, Nanika calls him only by name.
