Hunter X Hunter - Heaven's Arena Arc - NL Sub

Gon and Killua go to the Heavens Arena to train and earn money, where they unexpectedly find a mentor - the Shingen-ryu master Wing, who teaches them about the mysterious Nen. Gon and Killua are joined by a young child named Zushi, who is also Wing's student. Gon and Killua learn about Nen, discover their Nen types, and battle their way up the 251 floors of the Heavens Arena against powerful opponents with far more Nen experience than them. Unexpectedly, Hisoka is at the Heavens Arena as well, and agrees to fight Gon if he can prove himself a worthy opponent. Gon finds himself with a sudden opportunity to settle his score with Hisoka from the Hunter Exam.
