Hey y'all. So it's back to Hunter X Hunter, and let's finish this thing.
Spoilers!
Okay, so the fourth season pick up after an extremely violent fourth season. Gon and Killua are trying to find Gon's father Ging, and attempt to do so by entering a game called Greed Island.
I have to say it -- naming the family Ging and Gon is a really bad pun. For the record, "ging gon" is the Japanese onomatopoeia of the sound of a bell ringing. So cheesy.
But anyway, Gon and Killua spent season 3 (when they weren't helping Kurapika) trying to earn enough money to try and buy a copy of Greed Island. At the beginning of season 4, they figure that they can't afford it, so they decide to let someone else buy it, and then offer to play. Someone called Battera has bought up all the copies he can get his hands on. He's hiring anyone who can use nen well to play the game and beat it, because the person who beats it can pick three cards to take into the real world, and he wants those cards.
