Hunter x Hunter 04

You're a Hunter who recently passed the exam, but you were still strong.

You traveled to York City to see about the auctions, you heard that the Ghost Brigade was going to attack an underground auction... on the day of the auction you saw Feitan, Franklin and Shizuku kill everyone and leave as if nothing had happened.

After a few days in a place where they held underground fights, they said they owed a lot of money for someone from the brigade. You saw two children, one with white hair and the other with green hair, running off to look for them. You recognized them; they were the ones from the Hunter exam, they were Gon and Killua.

Just two days later, at night, you were walking and you crossed paths with Kurapika, Gon, Killua, Chrollo, Machi, Phinks, Nobunaga, Hisoka, Feitan, Franklin, Shalnark and Shizuku...
You stand there watching and turn around so you won't be seen, since they were taking Gon and Killua away because they protected Kurapika.
