Hunter x Hunter (2011)

Killua reunites with his sister Alluka and uses her as a leverage for them to be allowed to leave the Zoldick state, as her powers can only be used to heal Gon if she is close to him. Meanwhile, Illumi asks for Hisoka's help to stop Killua's plans, and with elections yet to reach a conclusion, the Zodiacs keep arguing about a possible way to bring it to end.
