I do not own or claim anything of the Mahouka Koukou no Rettousei Universe. I am simply a fan

"Onii-sama! It's time to wake up! There's school in an hour."

Responding to the melodious voice of his sister, Tatsuya's eyes snapped open. Gazing into his eyes were the luscious cobalt eyes of Miyuki. Quickly scanning the room, he noted Miyuki was still dressed in her nightgown, revealing her slender arms and legs. Miyuki tilted her head cutely and smiled.

It would have been a dream for any other boy to wake up to such an adorable sight, but as siblings, Tatsuya would never feel any more than familial love. As Miyuki stepped back, Tatsuya got out of bed with practiced ease.

"Morning Miyuki. Did you sleep well?"

"Yes I did! Thank you for your concern Onii-sama. Honami-san has made breakfast. Do come down soon."

At this juncture, Miyuki flashed a radiant smile before slipping out of her brother's room with her nightgown fluttering. Chuckling, Tatsuya quickly made his bed and proceeded on the way down to the dining room.

The house they currently lived was two storeys tall with two basement levels. It was a modern upper middle class house with living, dining and common areas located on the ground floors. Miyuki's, Tatsuya's and Honami's rooms were located on the second floor while basement 1 housed an entire range of CAD equipment only seen in top military facilities. Basement 2 was an arena for magic practice

The scent of bacon wafted through the air. Honami was definitely in the kitchen.

"Morning Tatsuya! Did you sleep well?" Honami's brilliant voice called from the kitchen.

Popping his head into the kitchen, Honami was presently dressed in an apron, cutting a motherly figure, especially the way she fried the eggs and bacon on the stove

"Good morning Honami. Yes thankfully I slept well. Thank you for making breakfast."

Miyuki then came out from the pantry carrying 2 cups of freshly brewed coffee.

"Thank you Miyuki."

Tatsuya received the cup gratefully. Taking a sip, Tatsuya nodded appreciatively to Miyuki,

"Just the way I like it. Thank you." Miyuki smiled.

"Miyuki wouldn't let me brew the coffee again. If I didn't know better, I'd think you two were married. She never lets me handle anything she can do for you.".

*Sigh* this again thought Tatsuya.

"Ah I guess we would if we could, but unfortunately circumstances don't allow it"

A clatter was heard in the kitchen followed by a shrill yelp.

"Tatsuya! Not all jokes can be said! You made me drop the spatula on my toe!"

At the corner of his eye, Tatsuya saw a stunned Miyuki with cheeks flushed redder than roses. Seeing Tatsuya gaze at her, Miyuki quickly stuffed her mouth full of scrambled eggs and averted her eyes in an unladylike manner to hide her embarrassment.

Tatsuya began to pick at the generous portion of bacon and eggs. Sampling like a connoisseur, his face remained blank. His eyes lit up and he began to eat at an increased pace, however it was still slower than Miyuki who was desperate to finish in order to avoid further teasing.

"Honami-san, this is good."

Hearty peals of laughter poured out of Honami

"As I expected you would taste the difference between today and the usual breakfast"

"So, do tell, what is the secret ingredient?"

Tatsuya looked at Honami seriously. "Its not that big a deal. I simply added a little spring onion is all"

Honami waved it off.

At home Honami was the housekeeper and mother figure to the two as their mother, Miya had passed away. However, Miyuki would insist on serving Tatsuya whenever possible. Seeing Honami and Miyuki fight over serving Tatsuya (Honami as a sense of duty) was often a comical sight.

Getting up, Tatsuya picked up his plate. Surprisingly, Miyuki's plate still stood at her seat. Sighing and shaking his head, Tatsuya picked up her plate in his free hand and walked toward the kitchen

"Leaving the room in such a hurry that she forgot her plate,"

He said placing the dishes in the sink.

"Thank you for the meal Honami"

Tatsuya turned and addressed Honami.

"Its nothing really, hope you enjoyed the meal!"

Honami replied cheerily. Tatsuya began to wash the dishes before proceeding back to his room to change.

Tatsuya walked down from the stairwell in his freshly ironed middle school uniform.

"Shall we go, Onii-sama?"

Miyuki called with both bags in her hands.

"Hai"

Tatsuya walked toward the exit and received the bag graciously.

"See you two later! Do update me if there is a need to!"

"We will be sure to!"

Miyuki answered on their behalf. Honami waved to them as they set off to school.

Bathed in the morning sun shine, Miyuki's light flawless skin was complemented by her long silky black hair. Tatsuya's tall and lanky frame with his accompanying quaint facial features made him slightly handsome if not for his usual expressionless face. At first glance, this unusual pair would seem polar opposites. The hidden similarity would be their ability as magicians.

He beheld a stoic, neutral expression while she bore a brilliant smile while speaking to the boy. At times his face would light up with hearty laughter and brotherly affection. Shiba Tatsuya and Shiba Miyuki, the guardian to the heir of the Yotsuba and the heir to the Yotsuba of the 10 Master Clans were on the way to middle school.

"Isn't that the Shiba siblings who always hang out with the Saegusa?"

"No its more like the elder brother who's into the Saegusa rather than the sister. Besides they act more like a married couple than siblings."

"Hmm I wonder what the sister would say if her brother starts going for the Saegusa"

Passing students usually gave the Shiba siblings a wide berth, similar to what distance subjects gave their kings or queens. This did not stop them from gossiping however. Tatsuya sighed and looked skyward while Miyuki's face turned a tad sour.

Magic is defined as the ability alter or change the eidos, the information body of any given phenomenon. This is done by activating a given magic sequence via the transmission of psion or thought waves, usually assisted by a CAD short for casting assistance device.

The Yotsuba were a secretive clan, thus only the head of the clan, currently Yotsuba Maya, the sister of their mother, would adopt the name Yotsuba. Since Maya did not have children, she was free to select an heir, the one being Miyuki.

Although Tatsuya was older than Miyuki by a year, he was passed over for clan head as the Yotsuba deemed his magic unsuitable. Tatsuya's Magic calculation area was dominated by 2 specialised abilities, namely decomposition and regrowth which do not alter the eidos like conventional magic but reconstruct or destroy them.

When Tatsuya was 6, their mother Miya conducted an experiment on Tatsuya to endow him with the ability to utilise magic by inserting an artificial magic calculation area. The experiment ultimately failed as it failed to create a large and strong magic calculation area although Tatsuya now had the ability to wield conventional types of magic, albeit at a mediocre level

Miyuki on the other hand, possessed great affinity for conventional magic as well as mind interference magic. Even at her tender age, she was able to construct and execute rough forms of Rank A magics such as Niflheim and Inferno, albeit without as much control as she would like.

Looking at Tatsuya, Miyuki asked,

"Onii-sama, are you going to club today?"

"Yes I will. There isn't a reason for me to miss it, after all I'm not scheduled to be at FLT today"

Tatsuya shrugged nonchalantly and looked at Miyuki. Miyuki frowned scrunching up her delicate features.

"Isn't Otou-sama a bit too unreasonable? Expecting Onii-sama to work and handle school at the same time?"

Tatsuya chuckled. Their father was a sensitive topic. Even when their mother was still around, he was with a mistress. When their mother passed away, he left their house to them and their mother's guardian Sakurai Honami and moved in with his mistress who was now their step mother.

This would undoubtedly spark resentment between their father and his children. Especially taking into account how short it was between the time from their mother's death to his next wedding. As a result, Miyuki felt resentment to their father and hatred to her stepmother for replacing Miya so quickly. Unsurprisingly, Tatsuya felt nothing much whatsoever to his father, largely because he felt his father did not deserve such a title. He felt his father contributed nothing to him whatsoever, even expenses were covered by the Yotsuba.

During the times where their father was brought up, Tatsuya would normally have to calm Miyuki to avoid hail in the middle of summer. Tatsuya rubbed Miyuki's head gently

"Its alright. I can handle all these well and still have time to spare. Besides I do like designing CADs,"

Miyuki sighed and nodded contentedly.

"Actually I also do not dislike Onii-sama working. The people at FLT recognise you for your contribution and talent unlike Oba-ue,"

Tatsuya smiled wryly at this comment thinking, nothing could be done.

Tatsuya worked for the Yotsuba at Four Leaves Technology, specifically at the 3rd division. The third division was famous for housing and producing the work of genius magic engineer Taurus Silver. Silver supposedly advanced specialised CAD technology by 10 years by introducing the Loop Casting technology which allowed one to continuously reactivate the same magic sequence. The actual identity of Taurus Silver was not of one, but 2 people. Head of the division, Ushiyama as Mr Taurus and Tatsuya as Mr Silver. Ushiyama specialized in CAD hardware while Tatsuya specialized in the software. Pairing them up was like Yin and Yang, both complementing each other's shortcoming to form a wholesome product. Tatsuya was disguised as Mr Silver in order to avoid attracting undue attention to himself as it was only one of two aliases which he held. The other being Strategic class magician Ooguro Ryuuya. It was by the command of Maya that Tatsuya avoid attracting attention.

"Hey Tatsuya, Miyuki! Over here!"

A booming voice called from behind. The siblings around turned to see 4 figures approaching them at a run, led by Saijou Leonhart, followed by Kitayama Shizuku, Saegusa Mayumi and Mitsui Honoka.

Miyuki waved at them with a smile while Tatsuya watched, amused. *Pant* *pant*

"Leo, next time don't just speed off like that"

Mayumi said while pouting cutely, causing Tatsuya to raise his eyebrows. This small movement did not go unnoticed by Miyuki, though minute, it signalled Tatsuya's amusement. Meanwhile, Leo turned a bright shade of pink before retorting

"I-i-its because you're not fit enough".

Miyuki frowned while looking at her brother.

Sensing Miyuki's glare on him he quickly spoke up

"I believe its about time to report. Shall we head on?"

The rest quickly nodded and they proceeded toward school for another boring day of lessons.

"Mayumi, have you thought about which high school you would like to enroll in?"

Miyuki asked casually.

"Hmm, although I haven't actually decided I would like to try for First High School."

Mayumi placed a finger on her cheek while thinking.

"First High is undoubtedly the most prestigious magic high school. It would be the obvious choice for Mayumi senpai as a member of the Saegusa clan,"

The pragmatic Shizuku added with a bored expression.

"Doesn't first high have the hardest entrance examinations?"

Honoka asked.

"Ahaha yes it does. Since I specialize in fortifying magic, I might not stand a chance,"

Leo added while laughing awkwardly.

"We're here" Tatsuya announced.

Shizuku was the daughter of the Ushio Kitayama, the majority shareholder of the huge Kitayama financial group. Ushio would normally not have permitted his daughter to enrol in a public school, but it was Shizuku's want to experience a normal school life that made Ushio relent. Honoka's parents passed away at a young age, leaving her at an orphanage. When Shizuku made her first friend in Honoka, Ushio readily invited Honoka into their residence and she soon became somewhat like a daughter.

Passing the time through friendly banter, they unknowingly reached the main gate.

"I'll be going now, see you after school!"

Mayumi separated from the rest as she was a third year, quickly joining up with her classmates, not before waving goodbye and sending a wink at Tatsuya, causing his cheeks to turn a tad pinkish much to Miyuki's chagrin.

"Hmm, so even the unusually reserved Tatsuya is not immune to Saegusa-san,"

Leo commented.

"Well I can't say she isn't beautiful,"

Tatsuya didn't have to look to know Miyuki was a tad fed up. Tatsuya chided himself mentally. Awkward silence permeated the hallway as the group walked to class. Another typical start to the day.

It was atypical for a Saegusa and Yotsuba to be friends, let alone close. A rift formed years ago between the current head of clans Saegusa Koichi and Yotsuba Maya when Maya was kidnapped years ago and Saegusa Koichi could not stop the kidnappers. This resulted in the dissolving of the arranged marriage between the two. Currently, Mayumi was unaware of their link to the Yotsuba, hence was able to be close to them.

Sensei was rambling on about the World War 3 in a monotonous voice. The constant droning bored most of the students out of their mind. It seemed like the billionth time Sensei spoke about this section. He was pretty much oblivious to the antics going on in class. Shizuku was currently using a terminal to communicate with Honoka while Leo was busy playing a game of online poker. Even at this age, card games are still relatively popular pastimes although they had been digitalized. Needless to say, all the above activities were banned during the procedure of class, well not that many cared.

The rule abiding Tatsuya was spacing out while looking out of the eyes were unconsciously trained on the school field where gym was normally held. A third year class happened to be at the field. Tatsuya watched as the boys played soccer. After a good 10 minutes, he looked around, only to spot the girls resting. His eyes zoomed in on only one target. Mayumi. Even at this age, Mayumi was stunning. Although Miyuki was considered more beautiful than Mayumi, but being siblings, Tatsuya could never see her as a lady.

He was currently gazing at Mayumi's graceful slender form as she moved around, her long legs and glossy black hair. Every movement she made was so flawless, so perfect. Mayumi swept her head toward Tatsuya, catching his eye. Mayumi blushed, seeing he had been caught staring, Tatsuya blushed a crimson red before turning his head back toward the class.

Miyuki sat behind Tatsuya in class, thus allowing her to view the whole scenario. Her face tensed, she clenched her fist, the classroom's temperature began to drop. Ignoring sensei, Tatsuya walked over and placed his hand on Miyuki's head

"Miyuki?" Tatsuya smiled.

"It's nothing, Onii-sama" Miyuki blushed at the close proximity and contact.

Tatsuya then returned to his seat. Miyuki sighed, it can't be helped, Miyuki thought.

The resounding sound of the be could be heard throughout school, signalling the start of lunch break. Tatsuya stood up quietly and moved toward Miyuki's that was currently swarmed with boys from class. Seeing Tatsuya approach, they automatically quietened and cleared a path for for him to pass.

"Miyuki, lets go"

"Hai!" Miyuki stood gracefully and bowed to those at her desk.

Signalling Leo, Shizuku and Honoka, the party proceeded down to the canteen.

"Class is really boring huh" Leo casually commented.

"Speaking of which, Tatsuya kept looking out of the window" Shizuku added.

Leo's eyes met Shizuku's. It was a given that Tatsuya's eyes would wander every monday during history. After all, Mayumi had her charms. Sensing Miyuki's mood darkening, Tatsuya quickly changed the subject

"Miyuki, how is it that you always manage to keep awake in class?"

"Actually I'm spacing out most of the time though I may seem to be paying attention"

"As expected of Miyuki, adept even at skiving" Tatsuya teased.

Miyuki pouted cutely, lamenting Tatsuya's teasing.

Seated at their usual table was Mayumi. Seeing Tatsuya, her cheeks reddened.

"So Mayumi, finally caught Tatsuya watching you during gym?"

Adding fuel to the fire, Leo smirked from the side. Mayumi's breath hitched. Tatsuya directed his slightly smirking face toward Mayumi, his eyes sparkling as he said

"Mayumi, you are beautiful you know." Mayumi blushed spectacularly.

Standing up she quickly informed the group she was going to buy food and left at a brisk pace.

One would expect a Saegusa to be immune to compliments or the like, especially since the Saegusa were known for holding large extravagant parties. However Mayumi was particularly susceptible to Tatsuya's words. Anybody other than those in question could see that Mayumi and Tatsuya were enamoured by one another but being stubborn and thick headed, neither would acknowledge anything.

As soon as Tatsuya and Mayumi were reunited at the table, the air became filled with awkwardness. Mayumi would sneak glances at Tatsuya occasionally. When their eyes met, she would quickly avert her gaze. Shizuku and Honoka sat at the side and sighed. Their eyes locked with one another and a look of mutual understanding spread across their faces. Swiping their mobile devices, they started typing rapidly. Standing up, Shizuku said

"I need to use the bathroom",

As she walked, Honoka bounded to her side and followed her. Not long after, Leo and Miyuki also left leaving just Tatsuya and Mayumi at the table. At the edge of the canteen, Leo was laughing non-stop at the awkwardness of the two being pranked while Miyuki, Shizuku and Honoka looked on, Miyuki not exactly happy. Tatsuya flashed occasional glances at the group, bemoaning his predicament. Mayumi on the other hand, was almost completely buried face first in her food.

"...Mayumi, there's rice on your face"

"E-eh?" She quickly brushed her cheek.

Tatsuya sighed and reached over, his hand swiping the rice grains she had missed. Upon contact, Mayumi's breath hitched and she withdrew quickly. It was then that Miyuki reappeared, knocking the awkwardness out of the air

"Onii-sama, Mayumi-senpai, Class is about to restart. Shall we go?" Miyuki smiled.

It was a stiff smile, showing her slight unhappiness with the predicament.

Throughout the remainder of class, Miyuki absent mindedly tapped her table with her fingers while staring blankly at her desk. It was obvious to anyone that she was distracted. Her forehead was wrinkled slightly from frowning, not once looking up from her desk. Thoughts of her brother and Mayumi coursed through her mind. Miyuki was ultimately jealous of Mayumi because she commanded Tatsuya's attention whenever she was around.

Ever since he first met her, he would divert his attention to her whenever she was around. It was not long after the Okinawa incident, thus Miyuki had only recently acknowledged her brother. Having her newfound brother taken away so quickly upset her, inviting jealousy to brew. Miyuki knew this was ultimately illogical, because Tatsuya still gave more attention to her and would prioritise her at this point but she could not help it.

She glanced at the source of her troubles. Tatsuya's blue eyes were dull with boredom. He sat upright in his seat, his posture perfect. As expected of a member of the Yotsuba. He shifted his glance toward hers and their eyes met. He smiled at her reassuringly, soothing her nerves. Looking back at the front, she finally began to listen to class.

Tatsuya walked elegantly toward the room of the soccer club while Miyuki walked in step with him, a comfortable silence amidst them. Tatsuya being himself, originally didn't intend to join a club. Although he did enjoy soccer, it was an unnecessary added responsibility on top of his already packed schedule. It was by pure chance that he was pushed onto the pitch for a tryout, resulting in his selection and membership. Similarly, Miyuki was not interested in joining a club, but she would watch Tatsuya's practice.

Miyuki sat elegantly in the stands. There were a few spectators scattered across the grounds, mostly girls. The soccer club was amongst the most popular as its members were generally good looking. As the members walked out of the locker room, a few members looked around and locked their eyes onto Miyuki. She saw her brother and waved frantically, grabbing his attention. Smiling back he walked onto the pitch. Training then began. Throughout the training, the boys would constantly sneak a glance at Miyuki. Somehow or other, she was totally oblivious to their glances, her eyes only following Tatsuya as he dribbled, passed and shot.

As Miyuki walked toward Tatsuya at the end of practice, a 3rd year boy intercepted her. Towering above her, he asked

"May I inquire, what is a princess like yourself doing here?"

"Good evening senpai," Miyuki bowed flawlessly,

"I was watching Onii-sama at practice."

"Oh. Who is your brother?"

Miyuki energetically pointed at Tatsuya who was walking toward her. He smiled and waved back.

"Oh I see. He looks a lot plainer than you. I really couldn't tell you were siblings."

At this, Miyuki's face darkened. "Don't ever insult Onii-sama"

A dark killing aura emanated from Miyuki, causing the Senpai to shrink back in fear. Suddenly, a hand landed on Miyuki's shoulder. Looking behind, Tatsuya had a very slight smirk on his face. Tatsuya then addressed Miyuki's offender

"Senpai, I suggest you and the rest of the guys keep your hands to yourself regarding my sister."

Tatsuya started walking toward the locker rooms while signaling Miyuki to follow him. She bowed quickly and fled after her brother.

It was night at the Shiba household. Tatsuya was down in the basement tampering with CAD equipment while Miyuki was diligently plugging away at the day's homework in the living room with Honami's supervision.

It was close to midnight when Tatsuya heard a knock on the door.

"Come in"

Outside stood Miyuki carrying 2 cups of coffee while Honami stood with some freshly baked cookies. Tatsuya smiled appreciatively when receiving his cup. Turning, he thanked Honami for the snacks.

"Honami, what do you think about actualising flying-type magic?"

"I think it would be great actually. Since its Tatsuya-kun, it probably will be doable. The problem would likely lie in making it useable for everyone."

Honami said thoughtfully. Miyuki looked on from the side, her eyes likened to saucers. In a household which was magically inclined, this would be a common conversation topic as it was one of the 3 great puzzles of weight-type magic. Miyuki listened intently as Honami and Tatsuya discussed the topic with fervor. Tatsuya's eyes gleamed with excitement and his body bent forward, intent on listening and rebutting to the animated Honami. Miyuki smiled to herself. Seeing Tatsuya happy brightened up her day.

Tatsuya motioned Miyuki over for her weekly CAD maintenance. Miyuki flushed a bright pink as she took of her clothes, leaving her only in underwear. Tatsuya averted his eyes and maintained his ever so stoic expression. Silence permeated throughout the room. Upon finishing the maintenance did Tatsuya break the silence.

"Miyuki, here is your CAD" he said smiling slightly.

Miyuki pouted, red faced and left the room. Honami chuckled lightly

"Alright goodnight Tatsuya-kun, don't sleep too late".

Tatsuya smiled at a leaving Honami.

Such was a typical day in the Shiba household
