Carbon Costume

Alluka (voiced in Japanese by Maaya Uchida and in English by Xanthe Huynh) is the second youngest child of the Zoldyck family of assassins, as well as only daughter, in the anime Hunter x Hunter.

She is Killua’s younger sister by a year, and is very close with him, as he’s one of the few people in the world that treats her kindly. The rest of the Zoldycks, including her parents and older brothers, locked her away because they felt she was dangerous, due to the parasite, Nanika, that also occupies her body.
Nanika has the ability to kill or heal, depending on the conditions, and as such, Alluka was locked away underground in the Zoldyck estate to keep her contained.

She has long, choppy purpley-black hair with a headband and hair accessories in the shapes of a variety of different emoticon faces, and soft blue eyes just like Killua’s. Her outfit consists of an outfit akin to a Japanese shrine maiden’s, in pastel colors, and long dark magenta boots.
