Last chapter:

Illumi just killed a man, before the eyes of class 1-A.
________________

Ilumi: So do you kids maybe know who Killua Zoldyck is?

Bakugo: NO, DAMN VILLAIN!!

Bakugo starts running to illumi to set off an explosion, but illumi stopped him before he even could do something. That was the sign that class 1-A started attacking him.
Well, except for some people.

Gon's POV

What can I do?! If illumi is here, then is hisoka also here, and why are they here for Killua? Wait, does this mean he is here too?! I need to find him.

?? POV:

How did they come here, and how do they even know I'm here..? What if they did something to Alluka?! I need to keep up my cover, or they might find out...

Some people were losing a lot of blood, and others were laying down unconscious, when someone walked to us. 

Gon's POV:

Hisoka...

Hisoka: oh, is see you are having fun without me~

Illumi: why are you here? Haven't I told you to stay hidden?

Hisoka: I was only going to tell that the so called 'heroes' or something are here to stop us.

Illumi: hmm, well, let's go then. We don't want to be caught.

And they disappear in front of everyone's eyes

Mr. Aizawa's POV:

I hope that my problem children aren't that hurt or worse, killed.

Aizawa looked for them, when he came there.

Most of them are almost bleeding dead, some are maybe even dead..

Mr. Aizawa: everyone who's hurted stay here recovery girl will heal you, the rest who aren't hurted please come with me.

Gon, Denki, Iida and Mina standed up.

Only 4 people...

Mr.Aizawa: Okay you four come with me.

Gon,denki, Iida and Mina followed Aizawa.

At UA

Mr.Aizawa: okay does any of you four know what they wanted?

Iida: I don't know anything, I called the pro heroes and waited for them.

Denki: one of them was talking about something kill ua.

Mina: no they were talking about a person.

Gon: they were talking about a person called Killua Zoldyck I think.

Mina: yes that was it!

Mr.Aizawa: okay, do you know anything else?

Mina: well one of them had long black hair, he looks like a girl, but I'm pretty sure he sounded like a guy.

Mr. Aizawa: Anything  else?

All of them stayed silent

Gon's pov

I shouldn't say too much, if I say too much. They might find out I know these people.

Mr.Aizawa: Okay, you can go back to your dorms and rest for a bit.

All: okay.

Mr.Aizawa pov.

Okay, I need to find this person called Killua Zoldyck.

After hours and hours of searching, Aizawa finally found something, a file that was saying  he was a orphan and is staying in this ****** orphanage.

This is it, I will go there tomorrow. But I won't go alone, I will go together with Mina,Midoriya,Denki and Iida. They are the only one's who know things and aren't  that hurt.

The next day

They were just done with breakfast when Mr.Aizawa came.

Mr.Aizawa: goodmorning, you four are coming with me.

Iida: Are we in trouble

Mr.Aizawa: no.

Denki: I almost thought this was about the electrical failure last week.

Mr.Aizawa: we already knew it was you Denki.

Denki: oh...

Mr.Aizawa: Anyway, we're going to a orphanage today.

Deku: why would we go there?

Mr.Aizawa: Well, I have found some information that the kid they are looking for is there.

Iida: that makes  sense

Gon's pov

I hope we find Killua there! I haven't seen him in 3 years..
Wait but how do I react when I see him, they can't know I know who he is.
I will just see what I do at that moment.

When they are at the orphanage

A random lady: hello, how can I help you?

Mr.Aizawa: We are looking for someone called, Killua Zoldyck.

A random lady: oh, I'm sorry sir, he ran 2 years ago away. But we do have still some of his stuff.

Mr.Aizawa: could  I get his stuff please?

A random lady: of course, wait for a moment please.

Mina: what now? If he isn't here, how can we find him?

Mr.Aizawa: Well I know someone who can find a person with their DNA.

Gon: That's amazing! Can we meet that person??

Mr.Aizawa: No

A random lady: sorry for the wait, I have found his stuff.

Mina:Why would anyone leave a skateboard behind?!

Gon's pov
Wait isn't that the skateboard I gave him?

Mr.Aizawa: thank you for bringing  his stuff, is it okay, if I take it with me?

A random lady: of course it's okay, anything for a pro hero :)

They go back to U.A and Aizawa leaves.

Mina: should we visit our classmates?

Iida: they are probably back in the dorms or are still in the hospital.

Denki: oh okay.

They are back at the dorms.

Momo: Mina, Iida, Deku and Denki, you're back, where have you been?

Iida: we have been to an orphanage, but is everyone okay?

Momo: yes everyone  is back at the dorms and is fully heald, with help of recovery girl ofcourse!

Gon: I'm glad everyone's fully recovered!

Meanwhile with Aizawa

Aizawa: So can you find him?

Trackoholic: Well I can find him, but you should know there are two different finger prints on, so we might first find the wrong person.

Aizawa: Well I think that's  okay since that person probably knows something about him. Let's try finding  him tomorrow

Trackoholic: Okay, I will see you tomorrow.
