The Person in the Sky ~ Crossover HxH x Bnha

Chapter Nine~ Nen

Killua maintains a good distance from the other...Hero's. If he wanted to find the fastest way to get home then he was going to have to follow them.

After all, if people called them Hero's then they should be the good people in this world. They must have a lot of resources that he could use to his pleasure.

The white haired male was equally being observed by almost everyone around him. Most of the hero students were sent to the hospital while the rest were tasked with returning back to UA.

It was an awkward walk back, as everyone was silent with only the crunching of there steps underneath there shoes being heard. Killua almost smirked from everyone's tense reaction around him, he even considered the thought of scaring them.

Soon the large group arrived at a huge building in the shape of an H. Clear reflective windows were dimmed from the night sky and a massive gate was surrounding the plot of land. The small creature that sat on the skinny blonde's shoulder placed his paw on padlock until it blinked green.

Killua was escorted down long hallways and through different doors before he reach a room deemed worthy for an office. He did a quick scan around the area before settling on a soft grey couch that was pushed near the center of the room.

"Welcome to my humble abode!" The squeaky voice of the Chimera spoke as he sat on his high chair. 

"...It's small."

Nezu laughed off the comment even though he felt a little angry by the comment.

"Anyways, I think it would be ideal if you would tell us all the information about yourself and a little about your world." Nezu stated as he clasped his paws together.

"Hah..." Killua scratched his fluffy hair, " Uh, my name is Killua Zoldyck, I'm 17 and I'm from a family of Assassins-"

"Assassins!!!!" The skinny blonde spluttered from behind Nezu.

"Assassination — It's the family trade. We all take it up. My folks see me as an exceptional prospect. But I don't see that I should have to live up to their expectations." He pointed out.

"Uh, do....you still....uh...Kill people?"

Everyone turned to the white haired male who was pretty nonchalant on telling people who he was.

"Nah. I'm not an Assassin anymore, I'm a Hunter. I'm so tired of killing. I just want to be a kid. Hanging out, doing stuff with Gon. That's it." The teen responded.

The skinny blonde decided to stay quiet as the words, I'm so tired of killing, repeated in his mind. This young boy has killed before which means he wouldn't have any trouble doing it again. He was going to have a hard time processing the fact that he wasn't from this world so there might be different rules from where he is from.

"Who is Gon? And what's a Hunter?" Nezu questioned as the other people in the room jotted down notes.

"Gon...." Killua trailed off with a sigh, "He is light itself. Sometimes he's so bright I can't even look at him. He's my best friend and one of the only people I can trust with my life...." The teen paused for a moment to think about the smiling green male before continuing to speak, " And a hunter are licensed, elite members of humanity who are capable of tracking down secret treasures, rare beasts, or even other individuals. We can also access locations that regulars cannot access."

" So you're like Hero's?" A purple haired female with a red mask asked.

"Eh. If your hero's risk there lives to kill and collect bounty's from there head then...Yeah." Killua rubbed his jaw and yawned.

The room turned silent at the teens words and couldn't help but think about how different there two worlds were. It was normal to kill for him...What a dangerous person.

Is this why the Villains wanted him?

" You're just throwing away you're lives then." A gruff voice spoke from under his white scarf. Yellow goggled covered his eyes and his arms were folded over each other.

Killua narrowed his eyes to the male but was cautious because he didn't know what his...Quirk was. 

"Risking your life and throwing away your life may seem alike, but are two totally different things. People who live at the brink of death never think of throwing their lives away." 

The two stared at each other for a prolonged period of time before they were interrupted by more questions coming from Nezu.

"What abilities do you have? And, What are it's properties?"

Killua could really go for a good meal right about now. It's about 3 in the morning and he didn't want to answer anymore questions.

"Right..." The teen just sighed, " Quirks don't exist from where I'm from. Instead we have something called, Nen. It is a technique that allows a living being to use and manipulate their own life energy, something like auras. Everything else, including a practitioner of Nen's individual skills, is based on the basic manipulations of one's aura flow. The Four Major Principles, in order of study, are called Ten, Zetsu, Ren, and Hatsu. Once you got that down, you learn more enhanced abilities...."

"What is Ten, Zetsu, Ren-"

"And Hatsu?" Killua interrupted The skinny blondes question. Ten or Point means to focus on the mind, reflect upon the self, and determine the goal. Zetsu or Tongue is to put it into words. Ren or Temper means to intensify your will. And Hatsu or Release is to put it into action. It's a series of steps in order to control your Nen." He explained.

The Hero's scribbled down notes so fast as if they learned something amazing. They were very interested in the thought of different powers in a different world, that they didn't even know existed. 

"There are six types of auras, every individual is born having one of these six different aura types. Upon learning one's own aura type, a student of Nen can set about learning to apply the technique in a unique way that suits their personality, which can develop into a unique skill." Killua raised two fingers and allowed electricity to run in between them, " Something like this. You don't the privilege to know what type I am just yet."

" This is very interesting...." Nezu nodded as he absorbed all this information. This...Nen seemed to be a very powerful thing. They were going to have to keep a close eye on this young teen...Especially since they don't know the full extent of his abilities.

" So what-"

" Nope. No more questions. If you haven't realized it's about 3 in the morning and I still haven't ate, drank, or slept since I arrived here." Killua stopped them from asking more questions.

" Zoldyck is absolutely right! Please settle arrangements for a empty room and prepare some food and drinks for him! He is our guest, so make sure he is comfortable!" Nezu smiled.

"Yeah, just call me Killua. " The teen stated, " And make sure you prepare some chocolate as well. I have been craving it since before I arrived."

" Alright Killua! We will discuss future plans in the morning. Please follow Eraserhead as he guides you to your new living arrangement's." Nezu instructed as he motioned towards the yellow goggled man.

Killua slid off the couch smoothly, making sure to examine everyone before leaving with the long haired hobo.

Nezu couldn't help but think about how this year was going to be.
