Killua X Reader

...Nen talk...

I sat next to Gon and talked until we heard knocking at the door.
We both got up and Gon answered it.

"Hey." A boy with white hair smiled.
"Killuaa!" Gon gave him a hug.
"Hm who's this." Killua said looking at me.
"Oh this is my cousin (Y/N)."
"Ooo so are you just visiting, or are you staying here." Killua asked.
"Apparently I'm gonna have to stay here for a while."
"Really."
"Ya my dad left me here. Which isn't a bad thing cause at least I have people my age to talk to." I said.
"Ya we can go on so many adventures together." Gon exclaimed.
"Oooo we can go on adventures! This might be much better than I thought it be." I slightly mumbled.

We all headed to Gon's room and talked about the Hunters Exam.

"Honestly I kinda want to take the Hunters Exam." I said.
"Same I want to take it again." Killua frowned.
"Hmm again?"
"I didn't pass the Exam." Killua said looking away from me.
"Oh well we can take it together then, if you want."
"Hmm sure."
"(Y/N) didn't you say that you have a nen ability or something."
"Oh ya, I'm not that strong but it's something I guess."
"What is you're ability" Killua asked.
"Manipulator."
"What can you're nen do?" Gon asked.
"We'd have to step outside to show you guys." I spoke.

With Killua and Gon blinking with curiosity, we went outside.
