Nanika

Nanika is a mysterious and ominous entity from the Dark Continent that coexists within Alluka Zoldyck.

Possessing god-like, reality-warping abilities, Nanika can grant any wish requested of it, no matter how impossible.

However, these wishes come with a terrifying catch: the greater the request, the more brutal and deadly the demands placed on the next person.

Despite its destructive potential and the fear it instills in the Zoldyck family, it shares a pure, deeply affectionate bond with Killua.

Nanika is a mysterious creature from the Dark Continent which came to possess Alluka Zoldyck under unknown circumstances. The two currently coexist inside Allukas' body.
