you were a skilled hunter killer, which means you kill hunters. No mercy. Your next tardes is in the hunter exams, therefore you entered the exams only to kill your target and drop out. As you were doing the running exam a kid with dark green hair that spikes up runs up next to you

"Hiya!! I'm gon! Who are you?"

he asks,you stare at him. He's not your target so you ignore him

"Hey... I'm talking to you.."

he mummbles

"Listen kid I suggest you piss off. Respectfully."

you warn him. He perks up almost instantly

"So your not mute! Alright! That's a start!!"

he yips happily

"Hey Killua! Come over here! I found this girl! She should be in our group!"

he yelled at someone. A white haired boy with blue eyes catch your gaze

"Killua..."

you repeat. You know this is an assassin. You have no worries though, you are physically and mentally better than him in every way.

"So join our group! You'd be a great help, plus I'd be good to have a girl in our group!"

he says. You can tell he's not going to leave you alone until you agree
