"Hey Rias, want to spar with me?"

"Pffffffft!?"

Naruto was confused by Rias' strange reaction to his normal question, the other day he had seen her watching him train with a look of longing in her eyes. Her confusion over a training request was not that strange, and he had sensed she was different than other girls during that time as well. He didn't know what was different about her, but clearly she was not normal, and if she didn't even raise an eyebrow at his clones, then there was something special about her.

He just asked her out of nowhere.

It was normal to start a greeting with a sparring request after all.

"So is that a no on sparring?" Naruto asked her.

Such a strange reaction to a really easy request, and Akeno behind Rias seemed to be giving a strange smile. It was after school, so there shouldn't be any problem with them having a decent spar.

"Uh... sure... I guess we can spar?" Rias was SUPER confused at the moment.

Her confusion did not get any better.

-Later-

Her confusion REALLY did not get better.

"Why are you stripping?"

"I want to follow the rules of this culture... when I was chea... when I was learning about history, I read that in this world it was tradition to spar naked... it's super weird... it was the Greek and Romans... the Europeans or something... and you're European right?" Naruto asked her with a smile on his face, getting ready to get naked so that he could spar with her in a way that would make her comfortable. "... Though the audience..." Naruto looked towards Koneko and Yuuto, both of which had joined Akeno to watch their leader spar with the guy they were curious about.

Koneko was sweating.

'... That energy... it came from him... I know it.' Koneko could sense that same dark energy deep inside of Naruto just by being near him, but at the moment it was hidden so deep inside of him it seemed like it was sealed. He clearly had some kind of Sacred Gear, something so powerful and evil that just activating it could cause waves of power that she had caused her to nearly kill herself in fear.

Rias blinked.

"Oh... you're not wrong... actually, you're really not wrong." Rias muttered under her breath when she realized that most countries across the world practiced nude sports and nude combat both during history trained or sparred with each other in the nude. Naruto seemed to misunderstand a few things, but the general idea of what he was getting ready to do out of respect for her was nice in spirit. "If you're not comfortable-"

She saw Naruto was completely naked.

Several faces went red.

"My my... somebody is gifted for his age." Akeno looked at Naruto's body with an eye that appreciated warrior beauty. He didn't have a single scar, but his body seemed built for murder and sport. Her eyes grifted below his waist, and her smile widened even more. "... and with room for improvement... when he's done growing, there will be a lucky lady... and I'll be there to steal him." Akeno grinned as she covered her grin with her hand.

She was so going to cuck some unlucky woman one day, she didn't know which woman was getting cucked by her, but she had plans to groom this boy into somebody amazing.

"... Perverted or not?" Koneko whispered to Yuuto.

She had no clue if this was perverted, usually she could judge it at a glance, but Naruto did not seem like he was doing this out of perverted intentions. He just raised his fists up and got ready to spar with Rias.

"Not, not normal, but not perverted... he seems to have misunderstood culture... but his wording for the misunderstanding..." Yuuto had caught Naruto say something that had his curiosuity peeked to be sure.

This world.

Naruto said the words this world for some reason.

"Okay then-" Rias tossed the last of her clothes, and she noticed that Naruto made absolutely sure to keep looking into her eyes. She smiled in satisfaction when she noticed that his cheeks turned pink at her nudity. She took her own stance, and she looked towards Akeno, who nodded. "-we can begin when Akeno gives the word."

"You can begin."

Rias knew she didn't have to pull her punches with this boy, considering he had matched devil physical strength while holding back when Sona tested him for school acceptance. She knew that if she punched him at full strength, it might hurt, but he would be able to recover from it. He had insane endurance, and she doubted a little pain would cause him any trouble.

"Lets have-"

She knew she didn't have to hold back.

"-guh." Rias didn't figure that meant that Naruto wasn't going to hold back either, before she got a foot to her face within moments. Her head jerked to the side, like a bobblehead she was shook by the attack and stumbled. Naruto practically flew passed her thanks to his own attack, and was in a position behind her. She was still stunned by his attack, so when he took both of his hands and punched both of her armpits, she left the ground and was sent into the air.

Pain.

Knowing you did not have to hold back was one thing, but she might want to try a little harder than just not holding back. She swung her leg back, but she hit nothing but air. She glanced behind her and didn't see Naruto there.

Pain.

Her face hit the ground when somehow Naruto had gotten above her, and kicked her in the back of the head. Her body indented the ground, and her face was imbedded into the earth.

'What the hell... when did he move... he was faster than Yuuto... and what was that weird hand to hand style?' Rias was helped back to her feet, her forehead was bruised from the hit she took, and she was sure to have a lump on the back of her head for that.

"Sorry, you're weren't ready yet... we can start over when you're ready okay?"

'No... I was ready.' Rias heard Naruto's words and she looked at him with narrowed eyes, before her gaze softened up. He seemed to genuinely think she had not been ready for him. She smiled to herself, not finding his genuine concern for her to be false in the slightest. She took a few steps away from Naruto, but this time, she silently watched him before the fight began.

The audience saw something different.

"Did you see him move?" Koneko asked Yuuto with her eyes narrowed.

She had barely even saw his movement between attacks, the only time she could follow his body was when he stopped to land an attack. The speed between attacks was nearly impossible for her eyes to track. She could somewhat track the speed of the man next to her, and she glanced over at Yuuto to get his reaction.

His hands were pressed together and shaking.

"... His speed reached speeds beyond mine for brief moments, there was a second at the beginning I lost track of him. It was like his body just flickered, it was there, then he was moving, and then it was not there and somewhere else... he stops using high speed once he gets in range of his opponent, and transforms his speed into brute force... speed isn't important to extremely close combat." Yuuto was amazed.

In combat, speed was used to get into you're opponents guard to finish them quickly, but it wasn't great for a long battle. In close range, speed was less important when compared to power and countering ability.

"You ready this time?"

Rias made the first move, she took a step forward to run at Naruto.

Pain.

'I made sure to keep my eyes on him this time!' Rias' took a blow to the chin, before she took one to the stomach, and then one to her sternum. Her feet were lifted off of the ground by the first attack, and she just was kept floating in the air as Naruto punched her body several times. He finally finished it with a high kick to her jaw. She went flying, flipping through the air, before she landed on her back.

She saw the sun was blocked out by a shadow, Naruto had jumped and was falling down on her from the air. Both of his hands were above his head/

She tried to dodge.

Her abs hurt, Naruto's punches had caused the center of her body to ache when she tried to move. She flinched as her body refused to respond, and the kick to her jaw had left her brain fuzzy and body slightly unresponsive. She saw Naruto was close to her, and he was in the middle of swinging his arms down to put her deeper into the ground.

She shot black demonic magic at him.

"WOAH!?"

Naruto took it to the center of the chest was launched by by her attack, unable to dodge it or stop his attack in time. Rias felt horrified when she realized she had just used her Power of Destruction out of instinct, the explosive power of her bloodline. She saw Naruto get launched through the air, and when he landed on his feet she sighed in relief.

'He took it... and his chest is only burnt?' Rias knew that people could endure her attacks.

It was still strange to see somebody who could tank her family power with only minimul injuries. It was as if her magical energy just wasn't dense enough to do any real damage to his body unless she put more effort into it. Naruto didn't approach her right away though, and he had a grin on his face. She was given a chance to breath and stand up.

His chest was healed.

In the time it took for her to stand up, the light damage done to his body had already healed.

"Sorry."

"It's fine, everything goes in a spar." Naruto grinned.

Rias took a different stance, a magic using stance.

"You're right, my Power of Destruction is pure destruction, but it seems I was underestimating how durable you were." Rias summoned forth her power in both of her hands, extending her arms to the side so that she could throw either attacks at a moments notice. "Sorry, I didn't mean to take you less than seriously..."

He was stronger than she was.

'The Power of Destruction is a type of demonic energy, Rias isn't on par with her brother, but fact is that she is still very powerful. Her demonic energy is high quality, pure, and she has large reserves. It's great explosive power is usually unrivalled... this guy is durable.' Akeno thought, but she had known he was durable.

Rias just revealed herself to be a devil to Naruto, and he didn't even blink at the use of her magic. Her using an ability he had not seen before just caused his grin to go wider.

"That's a nasty ability, okay then!" Naruto crossed his fingers in front of him

*POOF*

Rias started to sweat.

"Multi-Shadow Clone Jutsu!"

"Fuck..." Yuuto whispered as his eyes widened when he saw the field they were in behind the school was completely filled with hundreds, maybe even a thousand, Naruto copies that all got ready to fight Rias. "What the fuck?" Yuuto repeated when he saw each clone had a shadow, and their feet made indents on the ground.

They were flesh and blood copies!?

"Impossible... which one is real?" Koneko couldn't tell.

They all had the exact same scent, and he had evenly divided his chakra among ALL of them without his reserves seeming to have decreased much in the slightest. It was a monster amount of energy, and each of his clones had more energy than all of them combined together. The absolute insanity caused her to stand up and back away. The entire field was not covered in a layer of chakra so dense that she was starting to realize something.

They were all just drops of water in their energy reserves.

He was the ocean.

"I give up." Rias stopped using her power and raised both of her hands. The few hits that she had already taken had caused damage to her. Her body was shaken up, she was not a hand to hand fighter to begind with, but there was no way she was taking down this many Naruto copies at the same time.

"Wait, don't surrender... how about I don't use more than 500 clones?"

"Too much."

"... 100?"

"Not happening."

"2 clones?"

"No, you were already kicking my butt without using them." Rias deadpanned, she didn't want to fight him and his clones at all.

Naruto punched a clone, and it popped.

"See, they aren't durable, and one hit pops them... so..."

"No."

"Fine, no clones then." Naruto made all of his clones go away so that he could keep sparring with a real opponent. Rias nodded her head in acceptance, and with that the spar continued.

Pain.

Rias took a knee to the gut when Naruto crossed the distance between them, the magic in her hands fading away as she was launched into a tree. Her body cracked the tree, before shattering through it.

'I can't hit him when he is moving fast, but once he gets in close he hits me too hard for my magic to be any use... the only time I can hit him is when he is in the air.' Rias groaned, before she felt weight on her torso.

She looked up and saw a fist was hovering above her face.

She also felt Naruto sitting on her with his weight.

"... I surrender." Rias raised her hands up in surrender again, knowing that she was beat. The type advantage he had over her was just too hard for her to be able to ignore it. She groaned and relaxed on the ground, feeling bruising all over her body. She was going to have to take a long hot bath to get the pain out of her body for sure. "So when did you figure out I was a devil?" Rias asked with a smile.

Naruto just tilted his head in confusion.

"What's a devil?"

"... You're not afraid to punch a woman, are you?"

"I'll punch anyone, and you were spying on me training, so I thought you might be strong... I think you need to work on your hand to hand. You can take a hit like a champ, but... you aren't going to be a good partner for me to practice with." Naruto got off of her and crossed his arms in thought. He didn't know what a devil was, but honestly, he really didn't care. "Anyway, a lot of people call me a demon... so how bad can you be?" Naruto saw her questioning look and responded.

Naruto went towards his clothes, and saw Akeno holding them.

'Strong, fast, durable... and he heals from almost everything that hits him. Rias is the strongest person at the school, and he just turned her into fodder.' Akeno was smiling on the outside, but on the inside she was analyzing Naruto for everything he was worth. The smile never left her face as she replayed the battle in her head several times. She watched as Naruto got dressed, turning away from everyone as he did so.

She gave Rias back her clothes too, and the two of them made eye contract, and they shared a glance.

'... That wasn't training experience for him... he didn't get that skilled with just training.' Rias realized as she thought about it.

Those were movements honed by life and death battle.

He had experience putting his very life on the line, and his body was that of a man who had trained from an extremely early age. While even most devils didn't start combat training until they were in their teens, that battle showed her that he was just vastly more experienced than she was. The way he read her in battle was shocking, and how he countered her in a second after realizing she was a ranged fighter showed he knew how to deal with her type.

"So Naruto... just curious... how did you get so strong?"

"Strong? I mean, I'm pretty strong..."

"Who was your teacher?"

"Well, I guess my academy instructer Iruka-sensei started teaching me some of the basics first when I was a kid... and then I joined the military when I graduated and Kakashi-sensei took it from there... and now Pervy Sage is my master... so multiple teachers?" Naruto saw the color drain out of Rias' face.

Yuuto gripped his hands tightly.

Even Koneko felt some sympathy for Naruto, despite her fear.

'He's... a child soldier... he's an abused child like I was.' Yuuto gripped his arm. Naruto had been trained to kill and join the military from a young age, and he looked over at Rias to see the light of understanding enter her eyes.

She understood the truth.

"... So when did your training start?"

"Technically, it started when I was 4... but I started ahead of time. I used to go to the forest to throw rocks at targets, gather fish and mushrooms for dinner. So I say I've been training since I was three... does it count as training when you only do it because you're starving?"

"Why were your parents starving you!?" Rias shouted in shock when she heard that, horrified at the thought of a child being starved by his parents if he couldn't gather his own food and cook it. Naruto wasn't just a child soldier.

He was the literal definition of child abuse if that was the case.

"My parents died when I was born, don't even know their names. It's not that big a deal, sometimes I just ran out of money as a kid and needed to get food. I mean, I didn't have any parents or guardians, so what was I suppose to do. I've actually got a craving for some fish and mushroom soup thinking about it now..." Naruto grinned as he felt his stomach growl. Naruto saw their faces, and he saw the shocked and disgusted looks. That caused him to frown, before he sighed. "... Listen, it wasn't my parent's fault they died or grew up alone. I mean, my entire village hated me, they didn't know they were leaving me-"

Rias wrapped her arms around Naruto, biting her lip so that she didn't saw anything.

His entire village hated him.
He starved as a child.
He was trained to be a child soldier.

Naruto never got a childhood, he was alone and suffering, never getting to enjoy being a child like everyone else. It was no surprise that he trained so hard, and how he could endure so much pain during training. It wasn't even a surprise that he easily beat her like he did, she started training for combat as a teenager. He was barely more than 3 when he started to train on how to end people's lives.

'... Even I had more of a childhood than this boy.' Akeno came to the same realization.

How could one person endure so much abuse and still smile like he was, if there was anyone in the world that had more right to be a hateful, spiteful, revenge seeking bastard, it was Naruto. He was a genuinely friendly guy despite the right to hatred he had.

Naruto got out of the hug.

"Well, thanks for the spar Rias... see you later." Naruto was dressed and ready to get to training. "I've got some training to do-"

The second he tried to leave, Rias grabbed his wrist.

"... No..."

"What?"

"No, you don't have training to do. You've trained enough... you need to relax..." Rias was shocked when Naruto pulled his arm out of her grasp.

He smiled.

"I'm nowhere near strong enough right now, my training isn't even close to done. I'll see you later." Naruto then vanished from her view.

...

Everyone backed away from Rias when demonic energy rolled off of her in waves, her eyes a burning red color as she glared at nothing.

"That... that evil... foul... hateful..."

That village brainwashed the sweetest, most innocent, child they had. They turned him into a training obsessed monster that wanted to get stronger so that he could kill for them. Naruto was an abused child that had grown to love his abusers, and no amount of training would make him strong enough to get the people who hated him to just abandon their hate and love him. What was more, why did a village hate such a sweet boy filled with so much love and determination.

"... an orphan... he didn't get a childhood... didn't get love from anyone... they used him, brainwashed him, and I bet they would be glad to throw him away if he doesn't get stronger..." Rias covered half of her face with her hand, gripping herself so hard that she pierced her skin. Her magical energy killed the grass under her feet.

The more she thought about it, the angrier she got.

While her only gripe in life was that she was forced to marry somebody she didn't like, Naruto was undergoing emotional abuse and the physical abuse that came with military training. She had a love filled childhood where she got to grow up surrounded by her family, but he had a hate filled childhood with no family and no friends.

"Akeno... call my brother."

"Buchou?"

"Call my brother and tell him everything about this, don't leave out a single detail. I'm going to find a Stray Devil... nobody follow me." Rias started to walk away as she contained her power.

Yuuto stood in front of her.

"What do you plan on-"

"Move."

Yuuto shivered at that look in her eyes when she gave that clear order to him, and he moved out of the way without another word spoken. Instantly, he felt bad for whatever stray devil was closest to their location. Rias was in a bad mood, and she planned to take her anger out on whatever she could get away with killing. Koneko didn't even try to stand in front of Rias to talk to her, not even Akeno dared to stand between Rias and the target she planned to exact her anger onto.

"Jiraiya... Namikaze..." Rias whispered as she realized the name that was signed as Naruto's legal guardian.

Screw the Stray Devil.

She had somebody else that deserved her rage far more.
