Fallen Angel (Killua x reader)

Stronger than it looks like

After Y/Ns and Killuas talk in the airship, the final exam has come. Every participant that is left has to fight against another one and the one who wins gets out and the one that lost has to fight aigain in the next round.
In the first round, Y/N has to fight against Leorio.
After Gons win and some other fights, it was finally Y/Ns and Leorios turn.
"Good luck both of you!" Gon cheered
"Thanks Gon, I'll try my best to win against Y/N without hurting her. I mean, she's a girl after all!"
"You don't have to go easy on me because I'm a girl, in fact, I think you should use everything you got if ylou want to win Leorio!", Y/N said and walked into the fighting area.

"Ready? FIGHT!"

Leorio immediately ran towards Y/N and raised his right arm with his hand clenched to a fist and was about to punch her, when suddenly, the H/C girl took a step to the side and used her leg to kick him in the stomach.
Leorio flew into the wall and was K.O.

"Y/N wins!"
The girl walked over to Leorio, picked him up and brought the teenager over to Kurapika and Killua.

Kilua PoV.:
How is that even possible?! It looked like kicking Leorio out of the ring and into the wall was as easy as breathing  for her! I underestimated her... she's stronger than she looks like!

"I didn't know that I'm that strong, hehe..." Y/N had a foolish smile on her face. My heart began to race, my hands began to feel sweaty and I couldn't do anything about it!
"That was good" I said.
Gosh. That sounded so lame. I'm an idiot.
In my mind, I facepalmed myself for that. Before it could get any awkwarder, it was, gladly, my turn.
In the first round, I had to fight against  a guy named pokkle, but he's so weak, it wouldn't be fun fighting against him, so I gave up, hoping my next enemy would be stronger.
Here I am now, in my fight against a guy named Gittarackur.

No ones PoV.:

Killua went to fight against Gittarackur, but then he found out that this guy is his older brother Illumi. He looked at Killua and told him that he isn't able to have friends and feel love, that he's born to be an Assassin and that he is too weak to win against him.
After a short time, Killua gave up and walked outside of the fighting area. The white haired boy didn't talk nor did he show any other emotion than a mix of confusion, anger and hopelessness.
