Attack On Titan X HunterxHunter crossover : Unknown Walls

Chapter 2: Truth and Confusion

**Usually Nen cant be seen with the naked eye so you have to use Gyo but in since we see in a different dimensions Nen can be seen without using Gyo. So Gyo is basically useless in this dimension; In is the only attack that can't be seen with the naked eye...one MUST use Gyo***

Gon sits at his bed confused and worried. He looks at killua who wasn't waken up in 1 day. Killua had lost a lot of blood and half of his ribs were broken. Gon senses pick up foot steps and stops right at the door. Levi enters the room and grabs a chair and sits in front of Gon. "So you say you don't remember how you got here? I say bullshit...how do I know you are telling truth?" Immediately killua sits up. "Gon hates lairs and always keeps promises. He is the most honest person I know." Levi stares at killua mortified. Knowing that killua had broken his ribs and has blood loss he looked to be a great health. Levi stands up and backs away from Gon and killua. "What exactly are you? How?!!" Hanges rushes in as she hear Levi yell. Hanges stares at killua with her mouth dropped open.
The scouts run in and see killua standing. Their faces, shock and confusion.

"We don't know what to do so from now on you will be training with the rest of the scouts" Levi explains. "right now you will be talking to the commander. We need to find out your backgrounds and what exactly are you both because it seems that you both are abnormally weird. Don't take it personally."Backgrounds..." killua thought to himself. The scouts take them into a office, there both kids find a man with blonde hair. "Sit down and remain quiet until you are told to speak" Levi says. Levi looks at Erwin. Erwin introduces himself as the commander of the scouts. "Tell me then, you say that you don't remember anything? What is the last thing you remember before you woke up? Killua looks at Erwin. "We were with our other friends fighting against someone who we their nen ability is creating portals so we believe that both off us were sucked in and ended up here."Levi punches killua. "Enough of fairytales and say the truth" killua looks at Levi and his kill switch almost turns on when suddenly Gon grabs killua by his hand. "Calm down kil', its okay." Gon stands up and looks at Levi. "I thought we understood each other but guess not. What he said is right. There's nothing else to say, its not our problem if you dont believe us." Hanges intrupts the conversation."You mentioned abilities and this Nen. What is Nen?" Gon looks at killua and nods. "We'll show you but can we go outside. Sometimes nen can be messy."

They take them where they first found them. "If you try to escape I will kill you" Levi says with a stern face. Killua and Gon nod. "Nen is when a living thing uses and manipulates their own life energy most commonly known as their aura" Killua and Gon let out their aura. The scouts looked amazed at their aura. Strong and powerful yet calm and gentle, Levi says to himself. "There are 6 types of Nen users; Enhancer, Emitter, Transmuter, Conjurer, Manipulator, and Specialist. Im a Transmuter. Which allows me to change the properties of my aura; in my case I can change it to Electricity." Killua proceeds to change is aura to electricity. Hanges immediately starts jumping up and down. " wow!!!" She exclaims. She the only one to look happy while the other scouts including Levi and erwin look mortified yet amazed. Killua began to move. The scouts saw killua appear and disappeared every second. They were shocked. Killua stopped. "I forgot to mention that I am an ex-assasin. My family are all assassin's. I guess my family is quite famous for that reason. There you go shorty I'm being honest with you." Levi rolls his eyes "its captain too you brats." Killua smirks. "Ok captain...these are some of the techniques I learned as in assassin." Killua proceeds to morph his hand to a long vieny talons. Killua then proceeds to walk up to a horse and slash its heart out clean. The horse falls to ground dead. Killua places the heart next to its owner. Killua proceeds to do the rythms step, the shadow step, and snake awakens abilities. The scouts visibly now shaken. "When did you start learning these techniques?" Hanges asks. "Well to be honest since I was born. My mom would put small doses of poison in me. They would use Electric shocks on me. Basically I'm immune to poison and electricity shocks." Hanges unable to speak, walked over killua and hugged him. Killua quickly pushed her away. "How...are you alive?" Killua shrugged his shoulders. Connie and Sasha both looked at each other mortified. "What the fuck are you both?" Jean Exclaimed. "You tell me." Killua responded back. "Gon its your turn." Gon smiles at killua. "um well unlike killua I'm actually not immune to poisons or electric shocks but I am an enhancer. I guess I'm naturally talented." Gon disappears immediately after he says that. "Woah where did he go?!" Eren exclaims. "Hey up here!" They all look and see Gon up on a huge tree. They all gasp. "Wow thats so cool" hanges yells. Gon appears again infront of them. He forms a fist and takes his stance. "First comes rock, rock, paper, rock!!!" He screams as he punchs a tree. The tree falls over and Gon proceeds to pick up the big tree and swing it towards a half destroyed house.
The scouts are left with their mouths open. Levi is left impressed (which happens rarely tbh). These kids are something else. Gon proceeds to do the same but with paper and scissors. Erwin smiles and decided on something. "Cadets I want you to take on these kids." The scouts look at the commander. "What now?" Connie says softly. "You want us to get killed by these little kids" Eren yells. Erwin knew they would react like this. "Killua and Gon use only your raw strength." Killua and Gon nod. "Mikasa go first." Oh this will be something Levi says to himself. Gon goes against Mikasa. "Hi Mikasa, I'm Gon nice meeting you." Gon extends his hand for a handshake. Mikasa shakes his hand. "Just know I won't go easy on you Gon" Mikasa says with seriousness in her voice. "Ok then" gon says with a smile in his voice. "Lets begin" Hanges exclaims. Mikasa quickly throws punches to Gon giving him no time. She hits him with many punches. She uses her leg to leg kick him in the stomach. She uses her every ounce of her strength to punch him. Gon now laying in the ground  unconscious. Killua smiles he knows what Gon is up to. Gon sits up and smiles at Mikasa who had just started walking away. "Wow you are really strong. I didn't expect that. That last punch kinda hurted too." Mikasa looks at him surprised. Without giving her time to think he punches her in face and proceeds to kick her in the stomach.
Mikasa falls to the ground with a nose bleed. "Mikasa are you okay?" Eren runs to her. She stands up and smiles at Gon. Gon smiles back to her and proceeds to clean her nose bleed with his jacket. Levi stares at Gon with confusion. "Don't question him Captain shorty...that's his nature I also find it weird to be honest. Killua says smirking. Tch' alright then brat, Levi says to himself. The sunset was coming ahead. "Ok then I think thats enough for today. Tommorow from now on you'll train with the rest of us." Killua and Gon look at Levi. Both yell in unison "Osu Captain!" The scouts look at them confused. "No brats you salute like this" Levi proceeds to shows them. Then both kids yell "yes captain!" with the proper stance.
