Prologue

The boy stares at the old man. The old man that looks fragile, looks so weak, wrinkles cover his skin, his eyes almost unseen anymore due to that, and he even has to hold a cane so he can walk.

And yet...

"Youngsters these days." The old man sighed, head shaking in obvious distaste. "Just don't know how to treat their elders with respect."

He stands over them. Triumphant over them. A group of men that are still young, fresh, body trained and has months of experience living on the streets, knows how to fight and even brought weapons with them... But they all were the ones that were now on the ground, moaning and clutching their bodies in pain and close to the realm of dreams.

It should be obvious how the boy's response at such a scene.

"So... SO COOL!" He squealed, fists pumping together and stars practically sparkling in his eyes. "Old man! You are so cool!"

The old man glanced to the boy from the corner of his eyes, face still set to irritation. "Brat, didn't I tell you to leave before? Why are you still here?"

Rather than answering, the boy only let out another squeal and ran towards the elderly man. "Hey! Old man! Can you teach me how to fight like that?!"

A sound of a blunt object hitting something echoed in the area, followed by a yelp of pain. The boy holds his forehead that was bruised, his tiny legs stumbled one or two steps before he falls to his butt.

"Disrespectful." The old man speaks with a frown. "You're not answering my question, did your parents not teach you how to behave in front of elders?"

The boy grimaced, his face marred by shamed expression for a second. "Sorry..." He murmured. "I didn't leave because... Umm..." The boy fidgeted a bit as he glanced at the old man who narrowed his eyes at him before shifting it to the group of thugs that on the ground. "It just... I thought you might need help when those guys came."

The old man blinked once but his face remains stony. "And what makes you think a brat like you could do something to help? Isn't it better if you go and call the police?"

"I'm not a brat!" The boy snapped in an irritated manner. "And you're also only an old man! You're not supposed to be able to do something cool like that!"

"But I can." The old man replied simply. "But what about you? You should call the police instead of watching me from afar, one of those rude young men could have snuck in and captured you from behind."

"Now you're being rude! I can defend myself! For all you know I could be some kind of superhero in disguise and wanted to help you when you were in trouble!"

The old man quirked his eyebrow at the incredulous statement. "... Are you?"

The boy instantly deflated. "No..." He said sulkily.

The old man doesn't know whether he should laugh or berate the boy at his idiocy. Then again, he is a child so idiocy is not rare, so he set to a sigh. "I'm grateful that you were worried about me, but you should go home now, your parents must be worried about you."

"Nu-uh! I want you to teach me!" The boy refused and asked at the same time

"Teach you?" The old man blinked at the request. "Why?"

"... Because I want to."

"..."

"..."

"..."

"..."

"..."

"..."

"Okay." The old man said plainly.

However rather than looking happy or beaming, the expression he gets from the boy is the opposite.

"Ehhhh! You accepted it?!" The boy asked, shock was evident in his voice but there was disappointment that is obvious in there.

"Why?" The old man asked while blinking "Are you afraid? Want to go back on your word?"

"No, it's just..." The boy frowned before flailing his arms. "It's too easy! I mean! Aren't you supposed to give me some kind of super hard quest?! Like slaying a dragon or retrieving treasure from a pirate!"

The old man can only look blankly at the ridiculous questions that were asked by the boy. Just what were they teaching to younger generations in these ages?

"Or is this some kind of tutorial?" The boy muttered. "If that's so then it kind of makes sense, I get it easy." Hand rubbing his chin as his mind begins to wander to extravagant things in his brain.

"Boy." The old man called "What's your name?"

"E-Eh?" The boy blinked, appearing to be still in his own World.

"Your name, I'm going to teach you so tell me your name."

"Ah, it Issei. Issei Hyoudou! How about yours old man?"

"... Hmm, well you may call me Heng, Mr. Heng. Now why don't we go to talk with your parents? We're going to need their permission if you want to train under me."

Eleven years later

"Issei! Wake up! You going to be late to go to school!"

...

...

...

...

...

"ISSEI HYOUDOU! IF YOU DO NOT WAKE UP IN THE NEXT FIVE SECONDS YOU WILL GET ONLY RICE AND SALT FOR THIS WEEKEND!"

It was as if a nightmare just crashed upon him, the young man literally flipped from his position, a yelp comes out from his mouth as his eyes snapped open so wide that they almost popped out and his body hovering in air for about a second before he crashed back onto the bed.

"I'M AWAKE!" He yelled as loud and as clean as possible so he sounds already awake for a long time. "I'M JUST BUSY PICKING CLOTHES!"

His response came as soon as he finished shouting.

"LIAR!" His mother screamed back, even if it was muffled by the door but her voice is like a banshee that was enraged in Issei's ear. "YOU HAVE THREE SECONDS TO COME DOWN BEFORE I DECIDE TO DRAG YOU ALONG WITH THE BED DOWN HERE, AND BELIEVE ME YOUNG MAN, I WILL DO THAT!"

Knowing it's not just a mere threat but a promise, Issei somehow was already clad in his school outfit while having his toothbrush clamped between his teeth as he bolts out from his room.

The wooden floor that he steps unto let out a groan and grunt as the young man runs as fast as he could. And the moment he saw stairs that led downward, he does not waste time to use it as he jumped straight from his position.

Flipping in air that would make a professional acrobatic stare with awe, he positioned himself in air, keeping his balance as he landed on the ground, his feet softly hit the surface of the floor.

He spins his body, dashing to the dining room in an instant and when he enters, he is granted by sight of his father that is reading his newspaper and his mother that is setting food on the table while clad in an apron.

"Good morning son." His father greeted kindly, eyes still locked to the newspaper and he appeared to be nonchalant at the sight of his son that has his school outfit in a mess and has his toothbrush sticking out of his mouth.

His mother though, was the opposite. Scowl marred on her face, brown eyes scrunch in a sharp manner, lips curled to a thin line, one of her hands placed to the side of her hips. "You just woke up now didn't you?" She stated more than asked. "Seriously, this is your first day entering school after years, yet, you wake up this late. Are you really intent on going to school?"

"Nwopwe." Issei answered bluntly as he brushed his teeth and walked to basin. He turned on the water and spat a glob of toothpaste as he cleaned his mouth. "Never wanted to go to school. It's boring."

His reply was a ladle that smashed into the back of his head, making him tumble forward and smacking his forehead on the crane of the basin in a painful manner.

"How dare you!" His mother was all but calm as she yelled at her son. "Don't you know how hard your father worked so you can re-enter school?!" She demanded to him who is moaning and clutching his forehead in pain. "I knew letting you leave with Mr. Heng was a bad idea, even if he is a polite and kind old man but you were always being a troublemaker! You and Irina-chan!" She huffed and made a face that expressed regret and trouble at the same time as she recalled how her son behaved in his childhood.

"Not meaning to stop you honey, but aren't you supposed to go to school now Issei?" Her husband interjected, eyes never leaving from his newspaper. "Unlike my office, his school starts earlier."

She did not even bother to hold the gasp that come out from her mouth as realization dawned on her. In an instant, her angry features were gone as she moved with speed that would make an athlete proud, hands blurred and grabbing a pair of bread before stuffing it into her son's hand.

"Here is your breakfast! School starts in the next five minutes so you better hurry! The distance between here to there is about ten minutes using car!"

"Ehhhh?! Just bread?!" Issei whined, his eyes glancing over to the table full of food. "There is rice, miso soup and fried fish over there! Why am I just getting bread?"

"Because you woke up late and your class will begin soon!" His mother replied while glaring, making the young man flinch. "Add the fact you also need to meet the headmaster first since this is your first day!" She added with her glare sharpening, prompting the boy to squirm. "What are you waiting for?! Now go!"

"Yes, ma'am!" Issei saluted before he removed his blazer uniform, revealing the plain red t-shirt he wears underneath it, then he begins to tie it to his hip like a belt, prompting his mother eyes to twitch.

"What are you doing?! You will make your uniform wrinkle!" She chided, doesn't this boy know how tiresome it is to iron that outfit?! "And what's with that sleeping mask?! Are you going to wear it like that?!"

"I will move faster if I tie my blazer like this." Issei replied as he finishing tying his blazer. "Mom you, yourself said I need to hurry before, no need to worry, I will reach school by jumping from the roof and streets in five minutes." He said with a grin. "As for my sleeping mask, well! I just like to wear it!"

His mother stared at him, then she let out a small huff and shakes her head. "If I heard from a teacher you sleep in class during lessons..."

"Oh my! Look at the time!" Issei quickly changed the topic and chomped the bread. "See you later, mom! Dad!"

Before his parents can reply, the young man dashed to the door, popping his feet into the shoes and run with speed that would make Road Runner proud.

"ISSEI HYOUDOU!" His mother screamed once again and judging by the boy's speed that increased, he obviously heard her howl. Kasumi can't do anything but scowl at this, that boy better not be sleeping in class! Gods know he needs to get some knowledge; he rarely studies given his situation after all.

"Let him do what he wishes honey." Kazuya spoke softly as he placed his newspaper onto table and takes a sip of his coffee. "We both know Issei is smart enough to graduate from high school."

Kasumi allowed herself to sigh at what her husband said. "I know, I know, but you know him. That boy maybe has some brains, but he rarely uses it." She grumbled.

"Hahahaha! Well, what can you say?" Kazuya laughed at the statement, he knows well how true that is. "We, men more like to act rather than think."

"That is not something you should be proud of!" Kasumi snapped at him, making the man's laughter ceased. The matriarch of the Hyoudou family let out a small sigh, just barely 8 in the morning and she was already yelling like no tomorrow. She was about to go back to the kitchen when she saw something that makes her pale.

Kazuya of course noticed the sudden change in his wife and he asked. "What's wrong dear? You look like you've just seen a ghost."

Slowly, mechanically, Kasumi turned to him, hand holding something that make her husband pale as well. "I-Issei forget his GPS."

"... ... Shit..."

Meanwhile in another section of Kuoh city.

Truthfully Sona was not having a good morning.

Right now, she is supposed to be in school, in history class or at least in her office and checking documents that presented for her school. Today is supposed to be the first day her third year started after all, which mean new schedule and plan that has yet to be created for her school. However rather than doing that, now she is wandering around the abandoned mansion to hunt a stray Devil.

Normally, stray Devils only come out when it's night or close to, however this one is unique, rather than hunting at night, it hunts in the morning and day, since it knows that its hunters are busy at that time. Add the fact this is actually an urgent mission, the Devil just escaped from it master two days ago and uses this place as its temporary shelter.

So right now, she is forced to abandon her class and hunt this stray creature before it can escape or make preparations. What a bother, doesn't this thing know she has important things at a time like this? Then again, as a High-class Devil that rules this place, it's her duty to pulverize dogs that bite the hand of its owner.

'Robert Granger, stray Devil that escape after poisoning his master to near death. Sacred Gear, Might of Steel, a Sacred Gear that is capable to making the body of the owner as hard as steel, add the fact he still has his Rook piece inside him... He can probably already strengthen his resistance to Magic, which means I need to do inner damage to beat him. A combination of hot fire and water might be useful to damage his steel skin, making him rusty.'

She recalled the data she read about her prey and also formulated plan at same time. She wants this to be done already as fast as possible since this is taking her precious time, add the fact it's because they're supposed to be a few new students that are applying to Kuoh this year.

It wasn't a surprise that there were many people applying for Kuoh school, given its reputation as the best school in this city, and yet the price of it can be categorized as 'generous'. Obviously it's cheap because the school doesn't need money since it's handled by her family.

An unfamiliar energy brushed her sense, breaking her from her stupor and she instantly went on alert. Tracing where it came from, she found it a few meters away from her front, a place that she recognized as where the stray Devil is supposed to be when she sent her familiar for scouting.

"We're close, Momo, is everyone already in their place?" She asked her Bishop.

"Yes Kaichou, Tsubaki-fukukaichou, Tomoe and Reya are in their positions, ready and waiting." Momo answered.

It's just a plain and simple strategy, but effective. She, Momo and Tsubasa will confront the Devil directly. With Tsubasa as the main vanguard, she and Momo will be the ones that cast main attacks while the Rooks fight each other. And if Robert tries to escape, her Queen, Knight and another Bishop that are hiding and waiting, would come out and ambush him. The effect of the ambush will make Robert loss his balance for moment and when that happen, she and the rest of her Peerage will strike him down in an instant.

A simple but very well planned plan.

She and her peerage stopped when they reached the door, Sona can sense the unfamiliar energy she sensed now felt more intense, and it came from behind this door, which means that is where Robert currently resides.

She gives a glance to her peerage, sending a silent command to prepare themselves that they acknowledged by giving a nod to her. Then she pushes the door, opening it and revealing the room where they're going to fight soon.

It was the hall room of this abandoned mansion. There is nothing special in here other than furniture that was littered everywhere, covered by sheets of plastic so the dust does not dirty them. However, one piece of furniture in the middle though, not, and right now were used.

He appeared to be a man in the middle of his twenties. Face looked like a person that came from Europe, wavy short green hair, eyes clear blue, and clad in a clean black businessman outfit. He looked soft, tender and delicate, as a matter of fact this man can be said to be as handsome as Kiba. He sits on a sofa that was uncovered, staring at them with an impassive look.

"I did not expect that you would come after me this soon." He spoke, voice strong and stern. "I came here because I heard the ones that are responsible for this area were a pair of teenagers, and I was thinking maybe you were going to laze around."

Sona doesn't even bother to response to that remark, instead she went straight to the point. "Robert Granger, you are under arrest for poisoning your master. Surrender yourself and come with us peacefully, or suffer the consequences."

Robert's eyebrows narrowed at the threat and offer, then he smiled bemusedly. "You think you can beat me? You?" He asked in a voice that was asking if they were joking or not. "Little girls, you still have to train a few years to beat me."

"I will take that as a refusal." Sona replied, voice calm and collected. "Then, as one that is responsible for this area, I, Sona Sitri of the Sitri House will bring you down."

The space around her twitched. Multiple blue colored magic circles with symbols of her house appeared around her, all of them spun and rotated like a wheel, power emitted from them as they were aimed to the stray Devil in the middle of room.

"Momo."

The white haired girl did not respond to her Kings call, instead she chose to act. Flames begin to gather in her palms, swirling and dance like snakes, then wordlessly the Bishop unleashed it upon the stray Devil.

The stray Devil did not make any attempt to move or try to dodge. Instead he only stood there and allow the hot flame to swallow him, engulfing him and making the hall room bright and hot.

The Devils did not stray their gaze from their prey, despite the brightness that would make any person turned their eyes away, it did not bother them slightly. Then from the hurricane of flames that were swirling, a single silhouette can be seen inside it, and it came out.

Gone now his outfit, ripped, torn apart and burned by the flame, leaving only his pants. And gone as well the tender and delicate looking man, replaced by a creature that was bulky and huge. His skinny and slender figure turned buff and muscular, his pale skin turned to ash grey like steel, his blue eyes gone and turned to pure black orbs.

Tsubasa already moved when Robert came out and charging at them. She rushed as well, arms spread and ready to meet the stray Devil that run over like a bull. They clashed, arms meet arms, Rook meet Rook. The inhumane creature duo pressed each other's hands and were locked in combat, trying to overwhelm each other.

"Ku-!"

"You have quite a bit of strength little girl." Robert grinned as he towered over Tsubasa who struggled to push back the stray Devil. But it appeared to be futile as the man slowly but surely started to overpowering her. "The difference between us is high, even if we are both Rooks but I possess superior strength and endurance thanks to my masters experiment and my Sacred Gear!"

With a swift movement, the stray Devil grabbed Tsubasa's hand, then he yanked back the girl, spinning his body once and flung the blue haired girl away like a bag of potatoes, making her crash into the wall and created a hole.

Seeing this the man grinned, but that grin was soon gone as a stream of powerful jet waters slammed into him, swallowing him whole and sending him away, crashing in to a wall as well. And in that moment, twin pairs of flames in the form of a massive snake soared forward, eating the stray Devil's body and burning the wall and him.

"Tsubasa, are you fine?" Sona asked from her position.

Her answer come from debris and pieces of the wall that were being thrown away, the blue haired Devil soon came out from, despite their being dirt and dust that covered her, the Rook looked like fine. "I'm fine Kaichou. Though he is tougher than I thought." Tsubasa informed her King as she stands on her side once more.

"Don't underestimated him Tsubasa, like he said he is stronger than you so you can't expect to use direct attacks." Sona informed. "Remember your purpose."

"Right."

Their further conversation was cut away by another bit of debris and pieces of wall that were thrown away. From the hole where he crashed, he came back, just like Tsubasa, dirt and dust covering his body, but he looked fine, even if he is just burned and repulsed by jets of water, there is no sign of him being hurt or wounded at all.

"Not bad at all for a bunch of girls." Robert remarked, his hand clutched to his shoulder as he rolled it, creating noise by doing that. "I felt that actually, stings quite a bit. But," He allowed a feral grin to appear on his face, his normal teeth seem to become sharper than before. "It will take more than that to beat me."

The Devils did not make any comment or responded to him, they all were once again taking a stance and prepared to resume their fight, so did Robert as the stray Rook was ready to charge to them once again.

However, before they were able to make a move against each other, something makes them freeze.

"Huh? This is a pretty big hole."

Or someone precisely.

Stepping out from hole where Robert just crashed moments ago, is a young man. He appeared to be the same age with Tsubasa and Momo, brown hair that spiked and matching eyes. He wears a sleeping mask above his forehead, wearing a plain red t-shirt and black wristband on his right hand. A blazer tied to his hip, and bag carried on his back, he wears long pants that look very familiar to Sona.

... As a matter of fact, the blazer that is tied to his hip and his face actually look very familiar to Sona.

'This person! He is!' He's one of the new students that registered to Kuoh Academy this year! What is he doing in here?! He is supposed to be in school now!

"I know I shouldn't be wandering around; this city is not the same anymore like when I was child." He grumbled while looking annoyed. Then he begins to look around, and he noticed there were three girls who were facing a strange man that has strange colored skin. His eyes though, locked to the three girls rather than the steel skinned Devil and they brightened. "Ah! That's Kuoh Academy uniform!" He recognizes it since he has visited the school before entering and had seen the female students wearing that. "Hey! Can you point me in the direction to Kuoh Academy? I'm kind of lost since I'm new in here."

The trio of Devils can do nothing but gawk at the sudden statement that came out from his mouth, in their brains they thought the same thing. 'Can't you read the situation?!'

"Kaichou... Who the heck is he?!" Tsubasa asked in a whispery voice.

"He's one of the new students." Sona answered, it come out as an unconscious response actually since her brain was still processing what the hell just happened. How did this guy enter this place?! There is supposed to be a Boundary Field covering this place and it should notify her or her peerage members if someone enters this abandoned mansion! 'W-Was he already here before we come to this place?!'

Before the students of Kuoh Academy can respond to him, Robert already moves. With inhumane speed, he is already behind the newcomer who seems oblivious at his presence.

"I don't know who are you," Robert spoke coldly. "But you have bad luck for stumbling here. So, die!" He ordered while swinging his fist to the young man's head from behind.

'Shit!' The Devils from the Sitri group instantly snap from their stupor, spells prepared and limbs move, they all try to stop and save the young man's life, but knowing the distance between them is far and the young man is closer to Robert, it was futile.

A punch from someone who possess Might of Steel can be compared to a direct hit from steel. Such an attack would be more than enough to crush a normal Human's skull, add the power of Rook, the punch from Robert will be more than enough to make the young man's head be torn apart from his body, it was instant death if it hit.

But sadly for the stray Devil, it did not.

His punch miss, hit nothing but empty air as when it was only a few inches away from connecting to the man's head, the target was gone from Robert's view. That young man dodging the strike, barely maybe but the punch misses as he ducked, letting the fist soar through him. And before anyone can blink, the young man spun, his body twisting as he jumped, his knee soar upward and hit Robert's steel chin.

Much to the Devils shock, Robert who got hit actually stumbled from the attack. His eyes wide open as he unconsciously takes one step back from the sudden attack.

The young man did not stop, after deliver the knee attack, he spins once again, back flipped in air and once again giving a clean kick to Robert's chin, before he landed on the ground and steps forward, leg extended and kicks the abdomen of the stray Devil.

The stray Devil stumbles from the hit, he takes a few more steps back unconsciously. That... That actually hurt, unlike when being hit by the Sitri Devils spells, he really felt this one, the difference between them was quite big.

Still, that was not enough to stop him, he had been hit harder by his master. He buried his feet into the ground, keeping his posture firm as he slowly stands tall once again, his pure black eyes focusing onto his target that seems to look surprised he as he was still standing.

"That... That hurt boy." He commented, feral grin appearing on his face. "It seems you are more than you appear. But still," His eyes leering at the boy's leg that was twitching, obvious it was wounded. "My body is made of steel, a very durable steel! Do you think that puny kick can beat me?!"

Even if he was dropped from a five story house, there won't be any scratches or bruise marks on his body, as a matter of fact, he can tank missiles from point blank and he would not be wounded slightly. Such was the durability he possesses, so it was obvious a mere kick from the boy won't even harm him.

"You! Student over there!" Sona instantly yelled. "Get over here! It's dangerous and-"

"Hey." The young man cut her before she was able to speak, his head briefly turned to her, showing his face that looked calm and nonchalant, one of his fingers pointed to Robert. "If I beat him, can you guide me to Kuoh Academy? I'm late now and lost so..."

Sona truly doesn't know how to respond to that. Is this guy insane or what?! What the hell was he doing?! Provoking Robert like that! Doesn't he know right now he is in great danger?!

"Beat me?" Robert grin turned to deranged when hear that. "You?! A mere brat?! Beat me?! A little Human?! Truly your brain is really messed!" He then cocks back his right fist that was gripped tightly. "This time! You're going to die!"

SLIP!

"!?"

Robert eyes widened when the boy's right leg connected to the back of his right hand. Then, with one swift movement, the boy tilts down his leg, flowing Robert fist down, making the attack completely deflected.

Renewal Taekwondo

And he moved.

It was an unbelievable sight. Even to Sona who was watching. The boy's movement suddenly increased. He became fast, as a matter of fact, to her he only appeared as a blur. His right leg that was flowing Robert's fist down moved back, tilted upward and hit the man's chin, then with faster speed, he spins, leg rotating and he hit the stray Devil from opposite side of his first hit, then with much faster speed than before his leg slipped to Robert's behind and hit the man's back head.

3rd Stance Hwechook

The young man appeared a few feet away behind the stray Devil. His face remained nonchalant and calm as his hand now slipped inside pocket of his pant. "Body made of steel? That was stupid. Don't you know steel reflects waves multiple times stronger than flesh and bone? What do you think will happen if I give a strong wave to your head? You think your brain can handle it?"

POW! POW! POW!

As if answering his question, the impact instantly appeared. The stray Devil's head cocked multiple times almost in a second, it twitched to random directions as if it was vibrated by some kind of tool. Then, blood come out from Robert's mouth, his knees giving in as he slid down to the ground, face immediately meet the ground and his consciousness was lost.

The Devils that were witnessing the short battle can't believe their eyes. Granted they didn't have a problem handling Robert, but the stray Devil has shrug off their serious attack as if nothing in their short battle... And yet, here he was now, laying on the ground, defeated in less than thirty seconds by the boy.

'Who is this man?' Sona thought with surprise as her wide eyes stared at the young man with disbelief.

The man she thinks turned to them, his face still looked nonchalant, then the expression broke into a wide and toothy grin as his hand flashed a victory sign. "Can you take me to Kuoh Academy now?"

I got the idea of this story after watching GoH video. And by God, it was so awesome! I mean, the way the animation went, and how Mori-Jin clash against Ill-Pyo! Gaaaah! Why?! Why they did not make the anime and only put promotional video?!

Just WHY?!

...

Well, since I already rant like that, I guess I quite satisfied. Anyway, yeah, new story and all and bla, bla, bla, you know the deal. This is mainly crossover with GoH *for you who doesn't know it, search it in webtoon : God of Highschool* a very good comic and must read in my opinion

However there will be another elements included in here, one that related to martial arts *cough*Ranma*cough*1/2*cough*

There nothing much to say giving this is the first chapter so I will end it soon... What? Pairings?
