Killua and gon walked into the locker rooms after they finished going to the bathroom, which means that most of the other guys were in the middle of changing or were about done and we're putting away their clothes.

Killua and gon simply joined them. Of course, they both had a little bit of trouble with the lock because neither of them has gone to school before meaning they haven't grown accustomed to opening a master lock. Killua sighed and just started to pick the lock which he opened in a matter of seconds. He looked at gon who was just about ready to break the damned thing.

"You need help?" Izuku asked dragon who nodded in slight embarrassment. Gon told him the code which allowed Izuku to open it on the first try.

"Wow." Gon gasped slightly amazed. "Thanks!" He smiled at him.

"No problem that's what friends are for right?" Izuku asked, heading back to finish changing.

Killua scoffed and begun to switch out his clothes for the blue gym clothes.

As he took off his shirt, eyes traveled over to him. It's not that they liked him or anything. Most of the class was wary of him or neutral.

Killua had a skinnier figure yet he had rock hard abs along with medium-sized muscles, but the thing that drew the most attention was the scars that decorated his back. Many large scars were littered on his back with a hint of discoloration. Anyone who had the ability to see knows from one glance that this boy has gone through hell.

Gon and Killua were simply chatting as they changed. Gon would ask questions like what type of training do they think they are doing, what do you like about school so far and other random things.

The other class 1A boys knew for a fact that these two younger boys are best friends and they make it very clear. They also know that Gon can plainly see all the scars on Killua, yet he doesn't ask about it. Maybe Gon already knows? But what type of hell has Killua been through to get these scars? Are there more? Who did this to him?

Iida knew he couldn't just let this slide. This could be MAJOR child abuse that they could be dealing with. Most of the scars look years old, but that still doesn't change the fact that he cares about each and every one of his classmates.

Killua notes that the silence lasted an uncomfortably long amount of time and he was getting fed up with it. "Why are all of you quiet?" He turned around to face them. All eyes quickly diverted from Killuas scars and onto anything else.

Iida then spoke up with concern laced in his voice, "Why do you have so many scars?"

"Is it bothering you?" Killua asked in a monotone voice.

"It very concerning, so yes," Iida said, wanting an answer from the boy. He knows it's not his place to ask him that type of personal question, but it is a hero's duty to mettle when they aren't supposed to.

"It was training and that's all I'm going to say," Killua said, putting on the gym shirt and motioning Gon to follow him to the field where Aizawa is waiting for the class.

The rest of the guys in the locker room looked at each other in concern for the white haired boy. None of them believed that training was the whole reason for those scars.

"Should we tell Aizawa?" Kaminari asked nervously.

"Why shouldn't we? It's our duty to care about the well being of others." Iida said, closing his locker.

"I know... well..." Kaminari hesitated.

"Maybe he has a reason to be hiding it?" Izuku wondered out loud.

Todoroki just listened to the conversation. He was baffled about the amount of scars on the boy. Sure he had his own beat downs from his father during training, but nothing left permanent damage. During training, the worst it gets is him throwing up on the floor in pain or bruising, but none of them lasted for years except for the burn his mother gave him, but that was slightly different.

Todoroki knew from experience that Killuas scars did not come from training it was more severe than that.

"Let's just inform Aizawa about this. We might be dealing with child abuse." Todoroki said which causes many to tense up.

"We wouldn't want him to get more injured than he already is." Todoroki finished. The half and half boy has been through a lot. At first glance, anyone can tell that the silverette has been through more than Shouto and that's saying something.

"I agree with todoroki. The least we can do is tell an adult. I'm sure Mr. Aizawa will deal with the situation." Izuku said with his voice unwavering unlike most of the time where he nervously mumbles when he talks to the class.

"We can tell Aizawa after the lesson." Iida finished.

A mixture of nods s of agreements were given throughout the room as everyone made their way outside where Killua was standing next to gon as he talked to the girls about the training session that they were going to do.

"Everyone listen up." Aizawa stirred voice called out as everyone's attention gathered on him. "We are going to do a quirk assessment test." A bunch of students mouths opened to bombard him with a flurry of questions, so he said, "No questions asked. In too tired to answer them. But your gonna ask me anyway, so I'll say this: UA teachers are allowed to what we want, so I'm can skip the assembly and expect the student that comes in last place, so you better give it your all." He said assertively.

Before any student could speak up he announced, "Gon, you got first place in the exams. You go first." Aizawa said. "Go In that circle and grow the ball as far as you can. You can do anything

"Can I do the thing?" Gon whispered, referring to nen, cupping his hand as he talked into Killuas ear. "Sure, but nothing flashy," Killua told him in his normal voice.

"Ok." Gon understood him. No Jajanken this time even though he doesn't need it.

Aizawa and the hearing quirk users looked at the boy oddly, but let him continue anyway.

Gon walked to the circle, the students watching him with curiosity. It was common knowledge among the students that Gon had some type of enhancing quirk, but barely any of them actually seen his quirk in action, though.

Gon stood in the circle with the ball in his hand. He looked at it for a second before that same chime went off his head.

Card found. Would you like to collect card now or later? The robotic voice asked him and killua. "Later" Gon whispered under his breath.

Gon let some aura flow out, transferring it into his arm. As he powered up, a slight wind swirled around him, but it wasn't anywhere near the amount when he uses Jajanken. It was only a light wind pressure which some of the students felt even though gon was standing still.

The winds weren't the only thing that the students felt. Even though they didn't know about aura or life force they still hadn't one. It was simply locked.

Along with the wind, they slightly felt the warmth of his aura surrounding the room. It was a warm comforting feeling like the presence of a friend or the comforting warmth of a fireplace.

Gon lifted his hand up in the air and threw the ball at incredible speeds. If your eyes were fast enough, you can see the orange aura on the ball as it flew through the air, but no one besides Killua was that experienced.

The ball soared through the air, breaking through the clouds.

A few seconds later his machine beeped. "1000 yards."

The whole class had their jaws hanging in amazement at the power he demonstrated.

Aizawa gave a small lecture about being a hero then let Gon go back with the class where he was bombarded by questions. "That was so COOL!" Ashido smiled pumping her fist in the air. A bunch of other compliments was shot at him causing Gon to smile sheepishly, not knowing what to say until a few people asked at once, "What's your quirk?"

Gon looked at Killua who just gave him a look that only Gon could understand. He knew that Killua didn't want anyone to know the existence of nen or aura, so he made something up. "I have an enhancing type quirk." Gon said plainly.

The class gave him a look of, what the heck child? We already know that.

He then smiled as he thought of an answer, "I have heightened senses, better reflexes and heightened strength." Gon answered.

The class seemed content with the answer and stopped pestering him. A few people left his side while a few stayed to keep him company as Aizawa explained the other tests.

As Aizawa listed off the different types of tests, Gon smiled with an Idea. "Ne, Killua?" He asked him while hummed in response. "Wanna see who will win?" Gon asked his best friend.

Killua shield at the challenge, "Sure, but no quirks." Killua said referring to their own nen.

"Yeah." Gon agreed.

"Push-ups!" Aizawa shouted at the class.

The class got in pairs so one can count the others pushups. Killua and gon simply sat down and started to do push-ups as quickly as possible.

They were at about 300 push-ups when Aizawa woke up from his nap. He sat up, looked at his students who were crowding around someone.

Aizawa got out of his sleeping bag and walked over to the students. Someone better not be dead.

"What's going on?" He shoved his students out of the way so he can see what was happening. In the middle, there was a Killua and gon both doing push-ups without breaking a sweat.

"What the heck is the matter?" Aizawa grumbled.

"There at 500." Deku mumbled in pure amazement.

"You pass this. You know you can stop now." Aizawa told them.

"We can't stop yet. We are trying to see who can do 1000 first. That's our normal punishment if we lose a bet we made." Gon said, still doing push-ups.

"DONE!" Killua yelled, jumping up excitedly. "2000 sit-ups gon!" He shouted at his friends in accomplishment.

"NUUU!!!" Gon sulked, faceplanting on the floor. "I lost count..." Gon flipped himself over and started to do the 2000 sit-ups.

The class just looked at them in confusion. How on earth can they don that many? They shall never know the answer.

"What are you all doing?" Aizawa looked at the rest of Class 1A. "Do sit-ups." He pointed to the floor.

The class then scattered to go do their own sit-ups.

50 Meter Sprint

Gon and killua watched as the others went first. Iida had an engine quirk which made him faster he had 3.5 seconds. Tsu the froglike girl leaped a few times to the finish line making her get 5.3 seconds.

Gon and killua were up next. Gon and killua both didn't use the metal sprinting pads on the ground. Killua just plainly stood there with hands in his pocket while gon had one foot in front of the other, prepared to run.

Ready? Set. Go!

Killua seemingly disappeared out of thin air, reappearing on the other side of the camera.

".7 seconds!" The machine beeped.

"2 seconds!" The machine beeped soon later.

"Ugh, you beat me again." Gon moped.

"You'll be fine." Killua smiled fondly at the boy.

"I'm surprised you are that fast. Do you have a teleportation quirk?" Iida asked the younger boy. "Nope. Just training." Killua answered, walking away with gon.

This worried the Iida. All of the answers to why killua was so powerful is because of some sort of training. What did he train for though? How gruesome is his training?

The other students went, most of them getting decent scores, but Izuku was a different story. He didn't use his quirk at all. He didn't even have average strength or speed. Gon honestly was concerned about the boy while killua did give him a little bit of pity.

The next pair was Ashido and Ayoyama. Ashido got into a sprinting stance, while ayoyama face the opposite direction he was supposed to run. "What?" Killua wondered why he decided to face that way.

The machine then said go. Killua didn't have a good feeling about this.

Ayoyama felt a shiver run down his spine as he felt someone stare at him with such intensity. He realized that Ashido had already taken off, so he smiled in hopes that he could give himself more confidence that he could catch up to her.

Aoyama's smile didn't look like he was trying to reassure himself. In killuas perspective, it reminded him of a certain redhead magician.

Ayoyama placed his hands on his hips, looking at killua and gon. Ayoyama then smiled at them, trying to give them another reassuring smile that he will catch up. Why else would they be staring at him?

Killua gasped in horror. He turned to gon who was watching with a confused face.

SHWIINNGG!!!

Killua slapped his hands over gons' eyes and ran back to the lockers for there dear lives.

'WHEN IN HELL DID HISOKA HAVE A KID?!' Killua mentally screeched as he carried gon as he ran to the lockers.

Ball throw.

Since gon already went, he didn't need to do it again, so he plainly watched the other kids.

A few kids went, leading up to Uraraka going. She confidently threw the ball high up into the sky. It kept on going, and going, and going until Aizawas device beeped.

"INFINITY!!?!??!?!" Most of the class yelled.

"Woah! That so cool!" Gon cheered for her. She smiled sheepishly, rubbing her hand on the back of her head as compliments were being poured on top of her.

It was now Izukus turn. He seemed to be stressing out A LOT.

Gon tapped his shoulder before he could go to the circle. "You can do it." Gon said with a smile.

Izuku was stunned for a moment, then nodded his head with a slight smile.

Izuku hesitantly walked towards the circle. His mind running a mile a minute. This could be his only chance to use one for all in any of the tests. He stopped inside the circle, looking at the baseball in his hands. Allmight gave him this power. He believed in him. He believed that he could become a hero, so he cants mess this up. He can't get last place and go home. That is not an option.

Izukus eyes shot up. He quickly lifted his arm up.

Gon and killua both felt something odd. They immediately used Gyo.

Izuku yelled as he felt his quirk power-up, It surged through his arm like plasma stuck inside a container.

Gon and Killuas eyes widened at what they were seeing. They thought no one was able to use aura here. They even checked using gyo when the others were using their quirks, but it was the same paper-thin slice of aura which was their life force stuck inside their bodies, Not harnessed yet. Izuku, he was different. As Izukus arm lifted up as he activated his quirk on his arms. His aura spiked larger than both of gons and Killuas Ren put together (Ren: to enhance or refine; to put it outwards explosively)

The concerning thing is that on a regular basis when he is not using his quirk, his aura nodes are closed. However, when he does use his quirk they immediately open in one area which happens to be his arm.

It was a sudden burst of energy that didn't make any sense. It was dangerous. He could lose his life force is he ends up leaving his aura nodes open while activating ren. If he doesn't know how to stop it, then he would be in a world of trouble.

As fast as it came, it disappeared. There was absolutely no sign that his aura came out in the first place. He was in a state of Zetzu just like the one hollow, head of the phantom troupe, had permanently.

Gon and killua raced into a fighting stance, trying to find whoever stopped his aura. They need to find this person before he takes away their own nen.

The ball then plopped not very far away from where Izuku was previously standing.

"46 meters!" The machine beeped.

"What gives? I was trying to use it just now." Izuku asked a bit frightened as he looked at his hand, not comprehending what happened.

"Are you guys ok? You look stressed, kero." Tsu asked the duo. They loosened up their stance, letting their arms down from their protective stance.

"Yeah, we were just caught off guard because of Izuku," Killua answered partially faking embarrassment. 

"I erased your quirk," Aizawa said with his scarf floating in the air.

"Erasing quirks?" Gon questioned under his breath.

"What? Wait... I know you. You're the erasure hero: Erasure head! You can look at someone and erase their quirk." Izuku recognized him.

Killua felt the person hiding behind the wall move and get nervous. Because Killua and gon were still using Gyo, they could see that the hidden man's aura nodes are opened, but unlike themselves or Izuku, he was constantly using ten.

Killua debated whether or not to go confront the man. He showed no malice and was not intervening with them, but he was able to use aura and that made a huge difference in their decision.

Killua whispered to gon, "I'm going to see who is using ten over there. You keep an eye on Aizawa." He said as he performed Zetzu. Killua slipped past the group of students without any of them noticing he was gone.

Killua appeared behind allmight without him suspecting a thing. He then released Zetzu and stomped on the ground in order to reveal his presence to the unsuspecting man.

Allmight quickly turned around. He was stunned when he saw one of his students behind him. "Arnt you supposed to be with your class, youngster?" He asked wearily.

Killua simply retorted, "Are you supposed to be spying on us old man?"

"I'm not supposed to say this to you yet, but I'm your Hero course teacher," Allmight said.

Killua was fine with his answer. Yes, it will be annoying for him to be his teacher, but he had to deal with it. Killua still didn't know how or why he was using ten and that is what irked him the most. "How does your quirk work. I know its a power-up, but do you activate it like Izuku or is it constant?" Killua asked.

Allmight visibly tensed the moment he brought up Izuku.

Killua made a mental note that Allmight has something to do with Izuku.

"It's constant." Allmigiht lied, his smile faltering slightly. Killua knew it was a lie from the moment he said it.

With the amount of aura he was using right now, It's about impossible to believe that he keeps that up day and night. He's letting out the same amount of aura that killua and gon would use to defend themselves against the opponents who use powered-up punches, so they wouldn't break any bones. There was absolutely no way this man was telling him the truth.

"I'm smarter than you think, old man. I know your lying to me. Don't underestimate me." Killua said with his hands in his pocket. Killua knew that he was not going to get any information out of the man anytime soon even if he did tell him about the existence of nen.

Allmight watched the boy walk over to gon. Allmight strained his ears, so he could hear parts of their conversation, "He is keeping secrets from the class." Killua said. Gon then replied something that was not audible. Killua then said, glancing in almighty direction, "I know it's not healthy, but what are we supposed to do?"

"But he might lose it like that." Gon said a bit more upset and louder tone.

"Lose what?" Allmight asked himself.

"So what? It's not like we really know the guy, right? What's the big deal?" Killua said trying to convince one of something.

"I'm gonna tell him." Gon said in a normal voice, trying to walk to allmight.

"You can't do that. You know what bisky said. Imagine the damage you can do just by telling them about it." Killua seethed, grabbing gons arm.

"I don't care. He's definitely injuring himself by using it that much. He's not even fighting or anything." Gon said, pushing away killua who stepped in front of him.

"What am I doing wrong?" Allmight asked himself once more.

"SMAAAASHHH!!!" Izuku yelled causing Gon to stop in his tracks to watch Izukus aura spike once more. This time, it was denser.

All of Izukus aura was packed into a single finger just like gon does with Ja-janken but one finger. His aura spiked multiple times, uncontrolled. At the last point of impact, he used his powered up pointer finger and launched it into the air.

The ball flew gith into the sky. Killua and gon watched as it broke clouds apart, reaching its peak.

"705.3 Meters."

"We need to figure out how he is doing that. If we can't, we can always bring him to bisky." Killua said, still baffled by the boy. No one that belongs in this world can use nen besides him and allmight which is very odd. Even still, they are doing a terrible job at using it.
