Since it's a new story for me, It's Disclaimer time.
I do not own the right to Mahouka Koukou no Rettousei. All the characters belong to the wonderful Satou Tsutomu-sensei.

In this world, in any world for that matter there is always multiple versions of it. Each version having only a subtle change between the next one that follows. Because of this, the versions can be either very nearly identical or so different you could mistake it as something else completely rather than the same world with just one single change.

In the case of a young man called Shiba Tatsuya, one of these subtle changes could become a massive one on the world itself. More often than not you'd find him as a weak man in his time line, a time line which is heavily magic focused. But like this particular time line here, there are ones where he isn't a weak man. There are versions where he was born with magical might and there is one version where he can be compared to a God who is masquerading as a handsome human male.

He is a man who'd show power through fiery red and skill through a silvery blue.

…

It was the night before the opening day to the school year and Yotsuba Tatsuya lay alone and awake on his bed contemplating the 3 years of school that were ahead of him and how strange it could be. The reason for this being his younger sister, Shiba Miyuki. On paper Tatsuya was the son of the current head of Yotsuba, Yotsuba Maya, and Miyuki was his guardian, the daughter of the head's late sister, Yotsuba turned Shiba Miya. In truth, Tatsuya and Miyuki were brother and sister who were a year apart in age but in school years they were the same age and only just at that. Only the rest of the Ten Master Clans knew the truth about this. Even if you were to look at their powers, it seems to actually confirm who their 'mother's are. Tatsuya's power being downright dominating physically where Miyuki's is dominating mentally.

Truth be told, Tatsuya wouldn't even have to attend high school if it wasn't for the fact he was the heir to Yotsuba. His grades and abilities far surpassed High-school level but it was a must that members of the Ten Master Clans, and more importantly the heirs, go through High School. The fact about his abilities was definitely not a conceited one as he already had accomplishments for it, albeit it not through his actual name but under two different aliases. His school exam results are the only recorded data about his power but as it's High-school grade it doesn't mean all that much in comparison to his others.

And his other aliases are the other things that are currently playing on his mind as he lies down on his bed. His free time to perform those duties will be heavily decreased because of school work and its homework that comes with it. Any other student and it would be a hectic lifestyle which isn't good on their body but with Tatsuya it's different. You could easily call him a well-oiled machine. He can go without sleep for days, his time management is impeccable and above all that he has the skills and intelligence to complete his duties within the new time line that's approaching.

Though because of all this he never attended Middle School and instead concentrated on his lessons for preparation as the next head of Yotsuba along with performing his duties of his two aliases, kinda strange in actuality. Middle-School was compulsory where High-school wasn't. The renowned genius engineer 'Taurus Silver' and the Unregistered Strategic-class magician 'Ooguro Ryuuya'. These two aliases however and their connection to Yotsuba Tatsuya are unknown. The connection of Tatsuya to Ryuuya is the most secret as the connection is forbidden to be known outside of the group that helped create it. The connection of Tatsuya to Taurus Silver is different as it is Yotsuba based entirely. It's not something that is to be widely released as the Yotsuba clan is rather down to Earth despite their unworldly power and are quite secretive, some may see it as them not really enjoying being out in the limelight, and because of this Tatsuya can just tell whoever he wants to.

The exams itself were pretty simple, of course he didn't get full marks on everything. That was an impossibility, no matter how great you are there are always things you either don't know or aren't great at and there is always parts of that in the particular field that you excel at. Nevertheless Tatsuya still dominated the exams leaving everyone in his figurative dust with only Miyuki getting close if you could really call it that at Second place throughout. In the written exam he beat Miyuki by 58 points and third place by 70 points. In the practical exam he beat Miyuki, narrowly, by 15 points but by beating third place by nearly 300 whole points. Putting it all together and he beats Miyuki by 73 points and third place by nearly 400 points.

When the scores were released on the First High personal website, it's forums exploded talking about it. It was completely unprecedented and it wasn't just Tatsuya's scores alone. Miyuki as well had her own share there as despite only getting Second place, it showed she had immense skill to stick so closely to the side of the next Yotsuba head. The scores themselves were not released in one huge table. Everyone received a special code only they had to receive their own marks for overall and then each particular test but then on the front page was the top 3 in each three segments. Tatsuya and Miyuki took First and Second place while Third place changed for each segment. Though if you were to take Tatsuya and Miyuki away, then the third placers would be acknowledged more than they are being because their actual scores were actually pretty good especially in the written exam.

The forums exploded about Tatsuya for two reasons. First being the fact that his scores were so high it was borderline ridiculous and second being the fact that he was a Yotsuba and the only member of the Ten Master Clans for First High that year, narrowing down on the point that First Place was his anyway.

And as Tatsuya continued to dwell on how different his life will be because of High-school, the clock ticked over to the next day and continued on till sunrise.

…

As Tatsuya was the First Year Representative, Tatsuya and Miyuki left the confinements of their house early in the morning so they could get to First High early and miss the morning rush of people coming and going. Another reason was just so that they could be inconspicuous. And so with only the Second and Third years, that were tasked readying the school for it's first day of the new school year, seeing them they arrived on campus practically unnoticed and headed straight for the main school building.

"Miyuki, make sure you take a seat right at the back and as high as possible."

While his words could only be taken as bias and preferred place for a seat, his sister understood what he meant.

"Hai Onii-sama."

Tatsuya's light nod and smile was met by an overly happy smile in reply from Miyuki, somewhat of a typical thing when Tatsuya was to smile at her.

As they entered the school building, details about First High came into his mind and started to play as it ran in accordance with what he told Miyuki. Student life within First High could be compared with ways of old, the rich nobles as Course 1 students and the commoners as the Course 2 students. A social norm that was anything but right had hit the school when a call for more allowed entrants came in. A pecking order was created and a segregation that the First High Board didn't see fit to change and since then the animosity between the two courses grew and grew.

The Course 1 students were seen as 'Blooms' and the Course 2 students were seen as 'Weeds' because their uniform lacked the 8-petalled emblem of First High. 'Weeds' was a derogatory term and thus banned turning into a word that if uttered on school grounds can and will land you in trouble, though that doesn't stop the Course 1 students from using it and seeing themselves as better.

This superiority complex did not go with Tatsuya or Miyuki, they were both Yotsubas after all. To them they were just attending a school with a chance to make friends, in fact Tatsuya had a preference towards the Course 2 students and was the reason why he told Miyuki to sit at the back as high up as possible. It had the worst view and per society meant it was where the 'Weeds' would sit. Because they were Yotsuba and people who preferred privacy, Course 2 students were better people to befriend.

Splitting off from Miyuki, Tatsuya left to go to the backstage area of the school's auditorium where he would meet the members of the Student Council who would help him prep for the speech as First Year Representative. Planting a single, solid knock on the door to the back of the auditorium, Tatsuya opened the door and entered without a word.

Upon entering, he noticed that the backstage area was pretty barren with only a few what looked like Third years making final adjustments. With them not really being in a particularly noteworthy position they just briefly said 'Hello' to Tatsuya before carrying on with their work albeit nervously. Tatsuya was glad that that was the extent of their introduction, it was only the first day and a day where only the Welcoming Ceremony is taking place. At the very least, the First Years needn't be at school for the full day. Heck, they didn't really even have to see their home room or meet other students if they didn't want to.

The atmosphere that was in the backstage area stayed even when the members of the Student Council came to greet Tatsuya. The quiet room and almost oppressive aura that surrounded Tatsuya kept them all from making too much sound, even the new Student Council President Saegusa Mayumi who was known to be cheerful and boisterous. Unknown to the others, Mayumi had met Tatsuya before briefly and tried to get him to lighten up but he had just looked at her incredulously before turning away to speak in a rather heated conversation with Miyuki.

The fact Tatsuya brushed her off so easily irritated Mayumi but it also intrigued her. She was the oldest daughter of the Saegusa clan, she had marriage request left and right, she barely had to try to ensnare a male but Tatsuya was different. The reason was because he looked away of his own accord. When men looked at her, it would be until she passed out of view. That's how stunningly beautiful of a woman she was, a male couldn't help but stare at her. What Mayumi saw when she greeted Tatsuya for the first time was a look no-one had ever shown her before, it was a look that was bored in her presence wondering if she was going to continue by saying something or just leave. However despite that his features completely dissolved the whole façade of 'I don't care, go away' because even with the incredulous look he gave her, his expression was still inviting and to her, like many other women, extremely attractive.

Tatsuya was what you could call a 'Perfect Man', of course he was anything but that. His body was well built, it was muscular enough to be seen through his clothes but nowhere near the point that it could be considered ugly or ghastly. His facial features were what attracted women the most. While Miyuki took mainly after their Mother only taking the colour of her eyes from her Father, Tatsuya was seemingly a perfect blend. He took the handsome, manly features from his father in his prime but it was also softened slightly by the exotic appeal that the Yotsuba possessed. Then there was his eyes which were the epitome of why he could be called the 'Perfect Blend'. His right eye was red and his left eye was blue. Taking the red from his mother and blue from his father, it wasn't simple heterochromia either. It could be called a power struggle within his body or a fusion of the two powers of his parents. His eyes being the colour they were was without a doubt rare and in the day and age of magic, it was about as rare as being a Strategic-class magician.

All this made Saegusa Mayumi's job that much harder because she wasn't so used to being the chaser, she was always the one being chased. Her job was to tempt and ensnare Tatsuya as the rivalry between Saegusa and Yotsuba was a thick one even though it was one made by the Heads of each clan. Still though, it all made her that much more interested in him and her desire to continue was not in order to complete the job her father gave her but to understand the brain of the lone male that could resist her womanly charms.

Standing behind the curtain waiting to be announced so he could make his speech and get the day over with, it dawn on him that today was the day that the everyday magician would see what the Heir of Yotsuba actually looks like. Sure one or two of them have probably seen him before but they wouldn't have known that he was the Heir to Yotsuba. Unlike being a member of the other Ten Master Clans or even the Heirs themselves, Tatsuya's position was one that elicited more scares to others and also made them more careful around him. The Yotsuba's power was well known, they may have been lacking in numbers but there individual power was immense and made-up for it. What enforced that point was that Tatsuya was seen as the son of Yotsuba Maya, the Demon Lord of the Far East, who was either the strongest or one of the strongest magicians in the modern era. That fact was enough to scare near enough anyone, though Tatsuya always wondered what the world would think if they knew that while his power was just as immense as hers he had so much more and was the only counter to her magic. With Yotsuba Maya being known as a Demon Lord, his epithet as a God was entirely within reason.

"And next, the reply address from the First Year Representatives, Yotsuba Tatsuya."

Feeling a small pat on his back, he glanced quickly over his shoulder to see Saegusa Mayumi sporting a large smile. Raising his eyebrow slightly, he turned back around and walked onto the stage in the midst of the applause that was being sent his way. As he turned to face his fellow First Years, the applause was cut off as they all gasped slightly at the two different coloured eyes. The two colours that were known rivals as colours.

Adopting a slight smirk at their reaction, he begun his welcoming address.

…

"Ah Tatsuya-kun, I wasn't expecting such a beautiful address from you."

As Tatsuya walked down the steps from the stage into the back area, he was immediately faced with Saegusa Mayumi and brown haired male that was looked slightly unnerved but was doing his best to maintain himself.

"I'm hurt Saegusa-Kaichou. I can be just as poetic as anyone else."

Tatsuya's raised eyebrows and response, surprised not only Mayumi but everyone else in the backstage area. Everyone's first impression of Tatsuya was someone who was stoic but when you actually get him to say anything, he completely betrays that expectation.

"As a Yotsuba with the meaning 'Four Leaves', i'd like to think I can paint a very picturesque vision with my words."

He then betrays it even further by continuing his tease. That though can be considered as a rare occurrence.

"My My Tatsuya-kun, who knew you were such a gentleman."

Tatsuya only raised his eyebrows with a slight smile in reply to that jab knowing full well that she meant their first meeting. Tatsuya however didn't see fit to correct that instance.

"If that is all Saegusa-Kaichou then I must be going. I'd like to meet with Miyuki before she is swarmed."

"Yes, of course Tatsuya-kun. It is to be only a greeting today."

'Today?' That word played in Tatsuya's mind but nevertheless, he bowed slightly before picking up a bit of speed and leaving the backstage area.

Upon immediately leaving, he looked left first and was troubled by the sight ahead of him. Fellow First Years probably wanting to talk to him about things he doesn't want to think about right now, noticing that they saw him nearly a second after he turned towards them he turned to his right in a flash and was off to find his little sister before the pack of Blooms could even call out his name and they set off after him.

It didn't take Tatsuya long to find his sister, slightly longer than he initially had hoped for though. When he caught sight of her, he found her engaged in conversation with two girls from Course 2 both of which had short hair.

"Miyuki!"

Tatsuya's shout garnered the attention of everyone nearby as the tone didn't suit what he had or was to portray himself as. It was a tone filled with brotherly warmth and one which stirred a certain reaction that wasn't favourable but easily cleaned up.

"Onii-sama."

Miyuki had immediately turned round cutting off their conversation at the sound of her brother's voice and without thought called out the name she has done for years now. It was a slip-up that was very unlike her but also one that didn't really count.

By the time that Tatsuya had gotten to his sister and her two companions, the group of Blooms that were chasing after him had just caught up and the sight they beheld was a strange one, to them it could even be considered heretical. After all, it was the two students who had claimed the top two spots in the exams without trouble striking up conversation happily with two students from Course 2, students who are said to only just pass the First High exam. Though it should be brought up that the First High exam is the hardest out of the 9 magic schools in Japan meaning their scores are actually still pretty good despite the segregation.

"Look at those two."

"How are they speaking to them?"

Words of obvious contempt to the two Course 2 students ran through the school's courtyard. Words that only really hit one of the two Course 2 girls, it was pretty obvious it was going to happen anyway as she looked to be a shy and timid girl at first glance. The other one though was an upbeat and cheerful girl.

"My name is Shibata Mizuki. Nice to meet you."

"I'm Chiba Erika! Nice to meet you Yotsuba-kun."

Strangely, the timid girl who was Shibata Mizuki spoke up first eliciting the more upbeat Chiba Erika to join in and even introduce herself in a manner which completely fit her personality.

"Listen to them, being so friendly with Yotsuba-san."

"Who do they think they are?"

At the sound of the annoyed and almost jealous voices, Tatsuya adopted a slight smirk like he had done minutes before during the address.

"It's a pleasure to make your acquaintance. Please just call me Tatsuya."

As Tatsuya took on the role of the perfect gentleman, the Course 1 students surrounding them were left stunned. The two Course 2 girls however took it in their stride and replied happily.

"Alright Tatsuya-kun. Call me Erika then, calling me Chiba makes me feel stuffy."

"Then please just call me Mizuki too."

When the Course 1 students came back to their bearings, they saw Tatsuya escorting the three girls on their way out of the school gates to attend a nearby café to get closer acquainted.

This is my first and probably only story in MKNR for a long while, if i do decide to write another one.
With a new story to deal with came a new way of writing for me, personally i feel a small bout of apprehension towards your views for it.
Hopefully, you all like it in that regard and also the content that is my fanfiction.

I'm pretty sure everyone who has watched the anime or read either the Manga or Light Novel has wondered at some point what would have happened if Tatsuya was born with Magical Might like Miyuki was and in this story i want to put across what my thoughts are towards this.
I've only dealt with a few things so far in this chapter, and won't do much more in the next chapter which will be released sometime soon.
With Tatsuya's change, like i said right at the start is something that heavily affects this story or main canon at least.
One particular instance is what happens to their mother, Yotsuba/Shiba Miya and that is something i will address at a later date as i've already got some things down for her.

I haven't been lazy with this either and i've spent a whole lot of time on writing details and everything for this story.
For those who know me, they know i have wrote a number of stories for DxD but it isn't my favourite.
Strangely on this front, Mahouka is my favourite and it's why i'm so apprehensive to the new writing style and with taking so long to put a chapter out for it.
Writing up new spells, dealing with other components and trying to flesh out what i can with my own ideas and trying to get them to fit has been both fun and kinda hard.

So on this, I'm not going to plead but i strongly urge you to review, follow and favourite.
Review even if you have a slightest thought of something that i can address or correct in this story.

Thanks for you time, Ciao!
