A/N: Due to the lack of Tatsuya x Mayumi fics I decided to contribute with this fic. Hopefully you all find it entertaining. Honestly, I feel like I still haven't grasped the whole Mahouka-verse, so sorry if I got a few things wrong.

So, this will be a series of one shots between the two and the first few will be based around the anime so far. Obviously it won't be the same since it's a romance between the two so moments and scenes will be different, as you will see.

The first few will be in order but don't be surprised if I start jumping from different times. Like them having kids and then the next chapter they'll be back at school.

Also I might even jump to AU chapters. I like the idea of Tatsuya being Mayumi's guardian, so yeah. If anyone has ideas, scenes, or moments that they want to see don't be afraid to tell me. I won't guarantee I'll use them but you never know.

"Are you a new student? It's almost time for the ceremony."

Those were the first words she spoke to him, yet Tatsuya felt they held significant value. Not the words themselves of course, but the fact that she, the Student Council President, was talking to him, a weed and first year student.

Sure, he could take her words as the Student Council President looking after one of her "flock" but he knew better.

He researched nearly all the students of the school after all.

For security sake of course.

It was best to be aware of potential threats beforehand, common sense in Tatsuya's opinion.

It was his duty to look after his sister.

In short, he felt the Student Council President was speaking to him for a reason.

She wasn't called a prodigy for nothing, right?

From what he was able to learn from his research, she definitely deserved the title.

So, that all brought up a simple question: Did she know?

He immediately discarded that question.

No, she couldn't have known.

At best, she simply realized that he wasn't normal, and as much as he would say and think of himself as nothing special, much to his sister's chagrin, he couldn't deny that he wasn't normal.

Not in the slightest.

And as he stared at the blood-red eyes of the girl, really a young woman, in front of him, Tatsuya could easily see her as the type that would be drawn and find amusement by something not of the norm.

She also seemed like the type that didn't let an object of interest go once she was, well, interested.

Perhaps he was being too full of himself, thinking that she could be interested in him in any way, shape, or form but his instincts told him otherwise.

Basically, he should leave as soon as possible if he wanted to avoid future headaches.

He should stand up, politely thank her for her reminder, and be on his way.

"That's fine. I still five minutes."

And yet, for some odd reason he couldn't explain, he didn't do that.

"Well, that's true, but all the good seats will definitely be taken by then."

"Again, that's fine. The number of seats match the number of students so at least one seat in the back will be available."

"Oh?" tilting her head to the side, the Student Council President put a delicate finger to her chin while giving him a thoughtful look. "Yup. You do look like the type that likes to hang out on the sidelines and away from the spotlight."

That . . . that was rather scary.

Despite the smile and harmlessness in her words, the Student Council President shocked Tatsuya.

Was he that easy to read?

Tatsuya always thought his poker face was rather good but for his nature to be read so easily and by someone he literally just met...

It was something Tatsuya was not expecting.

Unaware of his shock (or maybe she was aware and was ignoring it?) the Student Council President finally introduced herself.

"Oh my. I haven't introduced myself have I?" despite her words, her tone was nothing short of amused.

Yes, to avoid future teasing, because Tatsuya was sure she was the type, he should introduce himself and leave.

"I'm the Student Council President, Mayumi Saegusa. Nice to meet you . . ."

"Tatsuya Shiba."

There, he gave his introducing.

Now was the time to politely excuse himself.

"Do you mind if I join you, Tatsuya?"

"It's your school, Madam President, you can do as you like."

Again, he went against all logic and stayed seated.

"Oh? Am I dictator now? Is that how you see me?"

"Not at all, but you seem like the type that gets what she wants." that was his rebuttal from her earlier, and spot on, assessment of himself.

"Hmm?" Madam President tilted her head back to look up at the sky as she took a seat beside Tatsuya. "I'm not sure if I should take that as a compliment or an insult."

Despite himself, and with no intention of doing so, Tatsuya let out a very small, but existent, smile.

What was this girl?

What was she doing to him?

What was wrong with him?

Besides his love for his sister, none romantic love that is, Tatsuya's emotions were practically none existent.

So why was he finding this girl's company so . . . so . . .

So, what?

He couldn't even identify what he found her company as.

There was something definitely wrong with him.

Yet, that didn't stop Tatsuya from responding.

"Didn't you say so yourself that I'm not the type that likes the spotlight? Insulting the Student Council President right to her face would be rather counterproductive, wouldn't it?"

"Well, that's true." she conceded before a bright smile adorned her face. "Then, thanks for the compliment, Tatsuya."

Her smile could easily be called dazzling, but despite that, Tatsuya didn't blush nor did his mouth hang open in awe.

No, he did none of those things.

He simply held back another smile.

It took more effort than he would like to admit.

"Ah." Madam President spoke up, drawing Tatsuya from his thoughts. "We really are cutting it close now. If we wait any longer we'll miss the start of the Freshman Representative Speech."

Tatsuya definitely couldn't have that.

Japan didn't need to experience an ice age.

"Well, this has been fun, but unfortunately I have duties to attend to." standing up with a little pep and a smile on her face, the Student Council President turned towards him. "I'll see you around, Tatsuya."

He gave a simple nod in response before he left in the opposite direction.

That was . . . unexpected.

But, truthfully, Tatsuya thought it was a good a start to the day.

He couldn't help but wonder what they rest of the day held.

"So we meet again, Tatsuya."

"It seems so. Are you following me?"

"First a dictator and now a stalker? Perhaps I should hire a PR agent? My public image obviously isn't as well off as I thought it was if you're linking me to those two things."

"No, from what I can tell your public image is fine. I'm sure your family is proud of how you carry your clan's name."

"Oh, you flatterer you." putting one hand on her cheek, the Student Council President used the other to give a playful wave.

What . . . what was going on here?

Miyuki couldn't understand.

Her onii-sama wasn't one to talk much.

Her onii-sama, while polite, would keep his words to a minimum and avoid any unnecessary words.

So, then why was he bantering with Madam President?

"Flatterer? I was simply stating facts. Nothing more, nothing less."

"Oh, stop you're embarrassing me." again her hand went up to her cheek while the other was softly placed on his arm.

Tatsuya made no move to remove it.

Was that just bantering?

Or was it-

"I never took Tatsuya as the type to flirt. Let alone with the Student Council President."

Those words didn't come from the stunned Miyuki, nor were they directed towards her.

No, they came from the cheekily grinning Erika and was directed towards the red-faced Mizuki.

They were flirting.

Miyuki didn't care if her onii-sama's face remained its usual stoic mask, he was definitely acting differently around Madam President.

"I'm surprised someone who's lived in the spotlight their entire life could be embarrassed so easily."

"Wow, does he work fast."

Miyuki didn't care for Erika's words but she was right.

"Madam President! You must have realized that you're talking to a w-"

"It's rude to interrupt a conversation, especially in such a manner, Vice President."

Yes, Miyuki, Erika, and Mizuki weren't the only ones who were a witness to Tatsuya's and Mayumi's interaction.

Along with the Vice President, other students had turn to watch their Student Council President talk (flirt?) with a weed.

"B-But Mada-"

"Enough." her playful demeanor quickly turned serious and left no room for argument.

Tatsuya had to give her credit, she was quick to assert her authority when she deemed it necessary.

It was to be expected though.

As a magician and a member of one of the most prestigious Ten Master Clans, it went without saying that she would see the battlefield one day.

"I sorry for such an unsightly display from one of my subordinates, Tatsuya." clasping her hands before her, Mayumi did what she thought Tatsuya deserved. She bowed her head and apologized. "Please accept my apology."

Tatsuya knew that her bowing to him, a weed, wouldn't earn him any fans, even without taking his eyes off of her and gauging the Course 1 students' faces.

Not that he cared.

Nor did he take his eyes off her.

"Please raise your head. There's no reason for you to apologize for such a thing, Madam President." doing as he said, Mayumi was quick to respond.

"But I insist."

"It was a simple interrupting of a casual conversation, and it's always possible that the Vice President had something important to inform you of." Tatsuya's response earned a glare from the Vice President, no doubt not liking the idea of being defended by him he was sure, and a pair of pursed lips from the president.

"Very well. I'll retract my apology. But," she continued interrupting his nod, "only if you stop calling me Madam President."

" . . . Ok. Then what should I call you?"

"By my name, silly." she giggled and Tatsuya couldn't help but find enjoyment in that laugh.

How peculiar.

"Very well." judging by the look on her face, she was expecting him to do so . . . . at the very moment. " . . . Mayumi."

"Now that wasn't so hard, was it?" seeing her dazzling smile while her hands were clasped behind her, Tatsuya gave a small smile of his own in return.

It was quite hard not to.

Neither one of them spoke after that, they simply held each others gaze, as if daring the other to break away first.

From an outside perspective, they looked like they were in their own little world.

Of course that wasn't true at all..

They were in a school hallway and very much being watched by a number of people.

"Man, he really does work fast. You should careful, Mizuki, you could be next."

"W-What are talking about, Erika?! Those two are obviously . . ."

"Hahaha! I never thought a person's face could turn so red!" not one to care of others opinion of herself, Erika let out a series of laughs. "But you're right. They might already be dating. Fast."

Those were the words that snapped Miyuki out of her shocked daze.

She wanted answers and she was going to get them.

So, with a chilling smile, Miyuki walked up to her onii-sama and tapped him on the shoulder.

"Onii-sama. Don't you think finding yourself a girlfriend so quickly is a bit rash? turning to face his sister, Tatsuya missed the blush that formed on Mayumi's face.

Others didn't, Erika's snickers proved that.

"Don't make baseless accusations, Miyuki. This is only the second time we've met." Tatsuya quickly but lightly scolded her. "Implying that Madam Pre-"

"Tatsuya." cutting Tatsuya off, Mayumi gave him a pout that would send butterflies running amok in a lesser man's stomach.

"Right. Implying that Mayumi would date someone so quickly without getting to know them is rather rude."

She was a member of the Ten Master Clans after all, and dating him, or anyone, so quickly would be unbecoming of someone of her stature.

Being scolded by her onii-sama, Miyuki was quick to apologize to Mayumi.

"No, it's fine. No harm done." Mayumi replied to Miyuki quickly before noticing the time. "Well, it was nice seeing you again, Tatsuya, but we have to go. Have a nice day you two."

"Once again, I'm sorry for my rudeness."

"Oh, think nothing of it. Besides," looking over her shoulder with a wide smile, Mayumi directed a wink towards Tatsuya that Miyuki didn't care for, "sometimes people just connect. There's really nothing we can do about it."

A/N: There. I hope this was as fun to read as it was to write, but I'm not entirely sure. Please give your feedback.

I tried to keep Tatsuya in character as much as possible but seeing as this is a romance fic, he's going to be a little OOC. I'll try my best to keep him stoic but it's those none stoic moments where there'll be romance between the two. As for Mayumi I believe I kept her in character. She's already shown to be playful and since Tatsuya responded rather well she kept it going.

I do plan on lemons in the future so yeah.

Just in case anyone was wondering.

I think that's about it.

Peace.
