Wizard 101 (Hunter x Hunter) (Killua x Gon)

Warning slight Yaoi
Killua works at a bakery but that's just a part time job. He's really a student at Wizard 101 and he's on a mission to defeat the Dragon clan. But while working in the bakery someone walks in that he remembers saving before.

*killua's flashback*
I'm on a mission to investigate some underground operation. I'm hiding on a ledge on the ceiling when I see these people bring in some kid wearing all green. He has black spiky hair and he seems to be mad at them. They bring him to a wall and chain him up he starts yelling at them but they don't listen. I see them pull out their phone and I hear them tell the person on the other side that they've caught Gon. My eyes widen at the name because I know that the leader of the Dragon clans son is named Gon. I look over at the kid to see him crying.
When the people leave the room I jump down without thinking to save the kid.

But what happens when Killua has to team up with the person he's tried to forget for so long. READ TO FIND OUT NOW!!!
