Hello there!

I just want to wish you all a year full of successes with the company of your family and friends.

I am sorry for the delay on this update, but the last months of the year are always full of work. But here's the latest chapter. I also want to thank my beta Fenerath for the support that he has provided me for this fic.

Also, before I start, I want to recommend to you all this anime called 'Terra e' or 'Towards Terra'. It is about a world in the future where the humans leave the Earth, and a group began to develop special powers. The normal humans began to hunt them and kill them, until the moment when they began to strike back.

Another thing is a challenge that I found made by Dragonofshadows115 for a Mass Effect & Mahouka Koukou no Rettousei. I saw it and believed that it could be a very interesting story if someone wants to try it.

Now, on with the story.

Miyuki was in a place that she didn't recognize, that looked like a big room in Western-style mansion. She walked over to the window, and saw a forest outside the building. It was a beautiful view, yet her reflection made her realize that she was wearing a baby doll that was sexier than anything that she would ever dare to use herself, and that made her wonder how she got there and why she was wearing those clothes. Her answer came when she heard the sound of a door being opened, and what she saw was a view that she had dreamed of many times, but not like this.

There in front of her, Tatsuya walked inside the room, wearing a bathrobe. By his appearance, he must have just come out of the shower. He was using a towel to dry his head, and looking up, his eyes meet hers.

"Well Miyuki, I have to say that it's a surprise see you here." stated Tatsuya with a smile on his face, and in a tone that made her blush.

Miyuki, embarrassed, didn't know what to say. Starting with the fact that she didn't know how she got here, she began to try to explain her situation. She suddenly got surprised, however, when she saw that Tatsuya began to walk towards her. Worried that he may be mad at her, she began to explain her situation.

"I swear I don't know how I got here, Oni-sama! The last thing that I remember was to going to sleep in my room, and then I was here!" Miyuki tried to explain.

"You don't have to worry, or even explain yourself Miyuki." said Tatsuya, with a voice that made her tremble. Not out of fear, but excitement that increased when he stroked her cheek after stopping right in front of her.

Miyuki was confused. She didn't know what was happening, but at the same time the emotions that she was feeling right then were too intense, too pleasurable, to just ignore. They become even more intense when Tatsuya picked her up bridal-style, and began to walk towards the bed, the very big bed that was next to them. When Miyuki felt her brother's arms, and how they pressed her body against his very strong and muscular chest… to Miyuki, it was like a tornado had taken her, just to caress her body with silk. However, her excitement rose to new levels when Tatsuya placed her on the bed, and began to settle next to her.

"ONI-SAMA! WHAT ARE YOU DOING?!" asked a confused but excited Miyuki.

"You know what I'm doing." was Tatsuya's reply, giving a sensual smile as he got closer to her.

"But we can't! We are real siblings!" Miyuki tried to reason with him, but somehow her body became hotter with anticipation. When he placed the tip of his finger on her belly, she felt a bolt of electricity run throughout her body, sending her more pleasure than she had ever felt in her entire life. That pleasure only grew as he moved his hand up her body. Soon, the invading finger was between her breasts. There was a storm in Miyuki's mind. On the one hand, she knew that she shouldn't be doing something like this, but on the other, the pleasure was too intense to resist. Thankfully, she didn't have to make any decision, because all thought exploded into pleasure when his fingers moved under her night clothes and began to play with the nipple of her left breast. The sensation was too intense for her, and all thought of stopping him were forgotten when she widely opened her eyes and had to bite her lips in order to stop a scream of pleasure that almost escaped her.

She could see how Tatsuya was enjoying her reaction, and she knew that she should be embarrassed, but that was not the case. No, she wanted to show him everything, to the point that it was like an obsession. Before she could place any of her thoughts in order, Tatsuya attacked her lips with his own. There was nothing innocent in the kiss that followed, and soon Miyuki was also participating in the kiss. The pleasure that ran through her body began to overrun her mind. After what seemed to be an eternity of pleasure, the kiss ended and Miyuki could hear Tatsuya speaking. To her, at that moment, his voice sounded as that of a celestial being that had taken her to paradise.

"I finally understand." said Tatsuya.

"Understand what, Oni-sama?" asked Miyuki breathlessly, due to the fact that she was still feeling the pleasure of the kiss, and the fact that his hand never stopped playing with her nipple.

"Why all this happened. Why we had to be separated since childhood." even with the sensations that she was feeling, that was something that attracted her attention and she wanted to hear his answer. "It's so that we could find our destiny on this world." Seeing the confusion in Miyuki's eyes, Tatsuya began to explain. "Miyuki, we are now from different families, and that means that when the time comes, I can make you mine. Forever." finished Tatsuya as he looked into her eyes like he wanted to write that last sentence in her soul.

Any words that Miyuki wanted to say were sealed when Tatsuya kissed her again, but the difference from last time was that this time it was more romantic kiss and one that Miyuki participated in from the beginning. When the kiss ended, Tatsuya began to talk again. At the same time, his hand moved towards her other nipple. Somehow, her night clothes had disappeared and she was in her naked glory, but she didn't care.

"Miyuki, you were born in this world to be mine." said Tatsuya as his hand began to move down her body, getting closer by the second to her most private place. While he was doing this, Miyuki was enjoying the pleasure that the contact of his hand with her skin created, but then he stopped just before arriving at her sacred place. When Miyuki looked to see what was happening, she saw how Tatsuya was now looking at her with a great seriousness and intensity.

"And I was born into this world to made you mine." With those last words, Tatsuya's hand crossed the invisible line and invaded Miyuki's Venus Mons, and began to attack it. No longer were they siblings, but a man that was marking his woman. By the moans of pleasure that escaped from Miyuki's mouth, she was more than fine with that, at least until Tatsuya stopped. When Miyuki looked at him to see what was happening, he smiled at her and said, "Say it." As an incentive, he began to move his hand again just a little. It worked, as Miyuki wet her lips with her tongue and began to talk.

"… I will become yours." she said in a low voice.

"Again." was Tatsuya's answer as he moved his hand a bit more.

"I will be yours." Miyuki said a little louder.

"Again." said Tatsuya as he increased his intensity.

"I am yours!" said Miyuki more loudly.

"Again!" His hand was now moving even more than at the beginning, making her the pleasure over power her mind and allowing her true desire to come to light.

"I WANT TO BE YOURS NOW AND FOREVER! I WANT YOU TO TAKE ME BY YOUR SIDE AND NEVER AGAIN LET ME GO! I WANT TO DEDICATE MY LIFE TO YOU! BUT MORE THAN ANYTHING, I WANT YOU TO USE ME FOR YOUR PLEASURE, BECAUSE THERE IS NO GREATER PLEASURE FOR YOUR MIYUKI THAN THAT!"

"Well said." said Tatsuya with a husky voice. Then, with a masterful motion of his hand, he sent Miyuki a wave of pleasure that made her lose all reason and allowed her to drown in pleasure.

"AHHHHHHHHHHHHH!"

In the Real World

"AHHHHHHHHHHHHH!"

With that cry, Miyuki awoke from her dream. After a moment that allowed her to recover from the experience, she realized that she was in her own room and that all had been a dream. A very pleasurable one, but a dream none-the-less.

"Miyuki-sama, are you ok?" asked Honami from behind the door.

"Yes, it was just a dream. Don't worry, I'll go back to sleep in a moment."

"Ok, but if you need something please tell me."

"Yes, I will do that. Thank you." With that, Honami returned to her room.

"What's happening to me?" asked Miyuki as she looked at the ceiling of her room. Ever since her talk with Illya-sensei, she had been having these dreams. While they had begun with simple things, like having a shopping date, or go to a park together, they had become more erotic in the past few days. All this had caused it to become harder to look at her brother during the Student Council meetings. She had to do something to stop those dreams, or she may end up doing something with Tatsuya that she would regret.

Second Course Magic Building

The incorporation of the new building on the grounds of the First Magic School a couple of weeks earlier had created a big change in the atmosphere of the campus, to the point that even people who visited the school for the first time could tell that the air felt different. However, it was a reporter who came to visit the school during the first week of the Second Course Magic Studies having their new teachers that made the best comparison so far: 'The difference between this building and the others is like the difference between art and science'.

Due to having an architecture that was basically a copy of the Clock Tower, thanks to Rin and Illya, it was like a window to their home universe. That is, if one ignored the computers and terminals that were also present in that place.

This just went to show how different things were in this new universe. In their previous world, neither Rin nor Illya could use even a VCR. Now, thanks to the memories they got when they first arrived in this universe, using a computer became second nature to all four of them. And after they saw how much help they could be for their research, they were happy to include them into their classes.

Speaking of classes…

"-and this is the theory behind why it's possible to store energy in crystalline structures." said Rin as the sound of the bell indicated the end of the class. "Well, that's all for today. Tomorrow, we'll be having the practical part of this class. Remember to study your notes! I'll be explaining any doubts you may have tomorrow before practice."

Soon the students were standing and leaving after they put their stuff and personal computers into their CSD. All of them were talking about how great the class was.

As for Rin, hearing them saying such things made her feel great. Now, everything that she said and taught was being truly appreciated by the students, although she still had pangs of regret. The main reason behind that was because she was including in her class knowledge that had been property of the Tohsaka family in her original world, and part of her was unsure about openly sharing her family secrets. Once again, she had to remind herself that this world was different. She was no longer Tohsaka Rin, but Ito Rin, and the only thing that the Tohsaka family had ever done for her was cause her pain, to both her and her sister.

Besides, being part of the group that was going to create a new path for the magic users in this world, by helping shape the next generation of Magi that were in the process of learning their own magic style, was something that made her feel proud.

Grabbing her things, she also left the classroom, and went to the place where the Thaumatology's combat club was about to have their session. Before she arrived there however, she needed to change her clothes and so went to the private teacher's rooms. With them being the only teachers in that building, and the only male among them being Shirou (who chose to change his clothes in the boy's locker room), they weren't worried about someone besides them getting in. In fact, they hoped that one day Shirou would enter while they were changing their clothes, so they could recreate one of their fantasies. Then again, that could be the reason why Shirou chose to change his clothes elsewhere.

Entering the room, she saw that she was the last one to get there.

"How was your class today One-sama?" Sakura asked as she was undressing.

"It was great. The kids really want to learn, and listen to everything that I said. There's a big difference with the kids from the previous universe." answered Rin.

"I know what you mean. Some of my students already read half the text book that I give them about alchemy." added Illya as she finished changing her clothes.

"The same happened with some of my students as well, and I'm sure that the same happened to Shirou-koi." said Sakura.

Soon, the three girls were on their way to the practice ground where Shirou and the students were waiting for them.

So far the training was very basic, because even if the students could access their magic circuits, that didn't mean that they had mastered them yet. So for now, all their training was meant to get more control over their own power.

At first, many of the students didn't understand why they needed to do that type of training, but when they were asked to do normal tasks, such as running quickly in a zig zag pattern or picking up something heavy, they failed or had some other problems that they shouldn't have in attempting those things. That was when the explanation by their sensei about how even though they can access their power, they still needed to get more control over it in order to be able to use more advanced skills made sense to them.

This session was to be the first training period where they would be learning a skill that was beyond the basic control exercises.

"Today is the day that we'll begin to practice a skill that, while it may be considered basic, it's advanced form can be a great advantage if you're fighting magic weapon users, or a great tool for those that want a civilian life." said Illya, making the the excitement of the students grow.

"That skill is Structural Analysis." added Sakura, causing strange looks to appear on the faces of the students.

"But, isn't that technique used only to train your control?" asked one student.

"There's more to that skill than what you're thinking." answered Rin.

"Structural Analysis allows the user to understand the composition of any object, even if it has magic on it. That also means that with practice, you can also find the weaknesses of any magic weapon." said Shirou, attracting the attention of the students. "It also allows you to understand how the magic works in an object. Do any of you remember when, in the demonstration for this club, that First Course student from the Kendo club attacked me with a Sonic Blade?" After he saw the students nod, he continued. "Then you'll also remember what happened to that sword. I was able to do that because I used structural analysis at that moment. I knew everything about that weapon, and how that magic affected it. After that, finding the weak spot was a piece of cake. In the same way, with those same skills you'll be able to understand what's happening when magic is moving in an object, the advantages and disadvantages, not only with your kind of magic but with Modern Magic as well. For those of you who want a normal life as Researchers, this skill will become of great help."

When the students understood those facts, they quickly become more excited. It was at that moment that Shirou took out a few jars and put them on some stands in different parts of the field. "Now, for today's practice I want you to break these jars, but you should know that I used Reinforcement on them. So what I want you to do is to take your time and use Structural Analysis on them, and when you're ready, I want you to take turns and try to destroy them. You can use your magic tools if you want."

Soon, the students broke up into groups around the different jars and began to use Structural Analysis to complete the task given by Shirou. After a few moments, one of them said, "I got this, so make room for me because I'm going to break this jar into a million pieces!" The speaker, Leon, then activated his magic tool that was different from the modern magic CAD. It looked like a glove and forearm of medieval armor. This was because the Second Course student liked the fashion of it.

"You better give up." was Erika's answer.

"Shut up, you annoying woman." replied Leon as he got ready to strike the jar. "PANZER!" Leon screamed as he punched the jar and… nothing happened.

"Ha! I told you, now make room so I can show you how it's done." With that, Erika removed her magic tool, a katana, from her CSD. She then used her mastery of the sword to give an excellent strike… that left the jar untouched.

"You were saying?" asked Leon with a smug grin.

"As if you could do it better!"

The two of them seemed to be about to start another of their arguments, when Rin stopped them.

"As you can see, this is not as simple as it might seem at first glance. When we reinforced the jars, we left a weak point on them that'll allow you to break them like regular glass if you manage to find it. I know that you want to advance, but if your base isn't strong enough, that will limit your growth."

With that, the students focused on their tasks once again.

While this was happening, three girls were walking in the distance to the exit of the school while talking with each other.

"So, are you all ready to our first girl's only night?" asked a smiling Mayumi.

"This will be my first time doing something like this." answered Miyuki.

"I still don't understand why it had to be in my apartment." replied Suzune.

"Come on Rin-chan, it'll be fun! Besides, this way we'll be all alone." insisted Mayumi.

And with that, the girls continued talking while they headed to Suzune's apartment.

Meanwhile, in another part of the city, some First Course students were gathering around Hajime Tsukasa in an abandoned industrial complex.

"I'm glad that you all answered my call." said Tsukasa to the students. "As you know, an irregularity has come to this world, a threat that will break the natural balance of our society, and that irregularity is the Thaumaturgy users!"

"YEAH!" said one student.

"THAT'S RIGHT!" another agreed.

"This world has an order where the elite ruled the lower class! It's the same in the magical world, and you are the chosen ones to lead the future of magic in this country!"

Again more students agreed with him.

"But now, we're facing a problem that should have never happened, all because a group of losers couldn't accept their place as your followers which is where they belong!" Looking around, Tsukasa smiled when he saw how they all agreed with him.

"Just because they learned a few new tricks, they believe that they are true magicians! That's a lie, and YOU are the only real magicians in the First Magic High School! Unless we do something to stop these Thaumaturgy users, their influence will expand to other schools, and that will lead to the ruin of this country! So I ask of you, for your school, your country, and your pride as true magicians… will you help me to stop them before it is too late?!"

"Yeah!"

"Yes!"

"Blanc!"

"Blanc!"

As they chanted, a lone figure of a woman looked at them from the shadows, having a sinister smile on her face. She was pleased with the results that she saw before her. She then disappeared into the shadows, without letting those present know that she was there in the first place.

Later That Night in Suzune's Apartment

Three girls were wearing their sleeping clothes while sitting on the floor of the living room. They had with them one of the greatest enemies of young girls, which was simultaneously also one of their closest friends.

Junk food.

"It's a really nice place you have here Suzune-san." said Miyuki.

"Thanks. I've lived here by myself for a couple of years now."

"What about your parents, are they working somewhere?" asked Miyuki.

"No, they were on a business trip three years ago, in Okinawa." answered Suzune in a soft voice.

"I'm sorry; I didn't mean to be rude." Miyuki said gently, understanding the meaning behind the name Okinawa for that specific timeframe.

"No, it's ok. It happened a long time ago, and I've moved on from that." replied Suzune.

During this, Mayumi was present but kept quiet. As a friend, she had already known why Suzune lived alone, and she regretted that she didn't inform Miyuki about it. There was also the fact that she knew that when Suzune lost her parents, she also changed from a normal, happy girl to a more serious one that was focused on completing her parents' dreams. She decided to change the topic before the mood became too dark.

"It's a shame that A-chan had a family appointment, and that Mari-chan had a date with her boyfriend." said Mayumi.

"It couldn't be avoided President. After all, you planned this in less than one day." was Suzune's reply in her normal tone of voice.

"We could have invited Erika-san and Mizuki-san." added Miyuki.

"I know, and I'd have loved to know them better, but when I found out that only the three of us were going to be coming, I knew that I had to take this chance." said Mayumi with some emotion.

"Chance for what?" asked Miyuki.

"For what? Of course, to talk about situation of Shirou-sensei and the other three teachers of course! We promised that we would never talk about them with anybody, but we never said anything about talking amongst ourselves!" Mayumi said passionately.

"I'm not sure if we should…" said Miyuki.

"We're keeping our promise about keeping the secret, so it should be fine." was Mayumi's answer. That was how Miyuki finally seemed to accept the main topic of their girl's night.

"I have to admit that I'm still very curious about them." added Suzune.

"That's right!" said Mayumi, happy that her friend agreed with her.

"I wonder how their relationship started." Miyuki contemplated.

"I would love to know, but so far the only thing we're sure of is that Rin, Sakura, and Illya were the ones that started the relationship." stated Mayumi.

"That's the only conclusion that we can get from the way that they acted when they admitted their relationship." added Suzune.

"Besides, Shirou-sensei looked very embarrassed about the situation. He also looked too shy to do something like creating a harem." said Miyuki.

"That's very strange, don't you think? I mean, they're a group of the most beautiful, talented, and influential girls that you can find among the magical families, yet they were the ones who chose to create a harem and offer themselves to a single man." added Mayumi.

"If you consider what they said when they admitted the real nature of their relationship… we can only conclude that Shirou-sensei was, and still is, a very important influence in their lives." said Suzune.

"But what could he do to make three gorgeous women love him to the point they agree to share him?" asked Miyuki. The truth was that she was also curious about the people that had saved and raised her brother.

"He must be an amazing person." stated Mayumi.

"You're forgetting how Rin-sensei and the others admitted that they kept all possible rivals away from Shirou-sensei." added Miyuki.

"To be honest, I don't know what to think about that." said Mayumi.

"I admire them." said Suzune, attracting the attention of the two girls. "It's because they chose their own future, and are willing to fight for it. When my parents died, I went to live with some relatives, and for a time the things were fine… but as the time moved on, I saw that they began to consider me as something that they could take advantage of to improve their status. Then, one night I heard my uncle talking about a possible engagement with an older man from one of the master clans who was already married. You can imagine what kind of engagement it was; they wanted to turn me into a concubine just for their own advantage. That's when I decided to begin to live alone."

Miyuki and Mayumi remained silent. As members of the Master clans, they knew that the Concubine System was an open secret, all under the excuse of increasing the number of strong magicians in a world where magicians were outnumbered.

"That's why I admire them, because they were able to not only succeed in their magical field, but also make the choice about how they want to live their lives, and are willing to defend their choice." finished Suzune.

"I know what you mean, but you have to admit that this is also so romantic!" added Mayumi.

"The three of them must be very confident and strong to be able to live as they are." said Miyuki.

"I'm also jealous of them." said Suzune again.

"Don't tell me that you like Shirou-sensei, Rin-chan?" asked Mayumi in a teasing tone of voice.

"Oh no. Besides, I like my head just where it is. What I mean is that I would also like to feel so deeply in love that I would be willing to face the world, and do anything just to be next to my loved one." finished Suzune. When she saw the way the other two were looking at her, she asked "Is something wrong?"

"It's just that it was a surprise to hear you said these things, Suzune-sempai." answered Miyuki.

"I never knew that you could be so romantic Rin-chan." added Mayumi.

"I'm like any other woman I guess… deep down, we all want a romance that'll define our lives." continued Suzune. "And talking about romances, what's the deal with Tatsuya-san that both of you have?"

Soon, a flush on the face of both girls appeared as they began to make excuses.

"What are you talking about Rin-chan?" asked Mayumi.

"There is nothing between On- Tatsuya-san and me" added Miyuki.

"Then, why is it that whenever I see Tatsuya-san, he's in the company of one of you?" Suzune inquired.

"I have a great deal of respect for Tatsuya-san." replied Miyuki.

"I just want to challenge him, because it's fun to compete with him." was Mayumi's answer.

"Really? Because for a moment I believed that both of you were interested in him. Considering that his role model is Shirou-sensei, a man that beautiful women find irresistible, who knows what else he could learn from him? Maybe he's considering starting his own harem as well? If that's the case, then you should be happy that he won't have to choose between you two, and everyone can have a happy ending." said Suzune with a teasing smile.

"RIN-CHAN/SUZUNE-SEMPAI!" was the answer that she got.

Not wanting to lose the game that her longtime friend seemed to be willing to begin, Mayumi decided to counter-attack.

"By the way Rin-chan, you seem to be very interested in Tatsuya-kun. Could it be that you have your eyes on him?" asked Mayumi, never realizing that Miyuki gave more attention to hear her answer.

"You can rest assured, while I respect his strength and knowledge, and I believe that he is a good person, I don't have any romantic interest in him. To be honest, it would need something amazing to happen to made me feel in love with him."

When both girls heard that, they felt like a weight was removed from them. But at that moment, Suzune dropped another bomb.

"But the school year had just begun, and I think that there's plenty of time for amazing things to happen. So who knows what could happen in the future?"

"Well, if that is the case and we end up falling for Tatsuya's evil plan of having his own harem, I'm happy that one of my new 'sisters' is a friend." answered Mayumi while giving off a shaky smile.

"Does that mean that you really have considered being part of his harem?" asked Suzune.

"Only if you also joined." joked Mayumi. "What about you Miyuki-chan, are you willing to fall into Tatsuya's harem?"

"Me? I mean I-you see-" Poor Miyuki couldn't make an answer, especially because the topic was about her beloved Oni-sama. That, and the fact that she was remembering the dream that she had earlier that day, wasn't helping her.

Soon, the laughter of Mayumi and the smile of Suzune returned her to the reality. And the girls' night continued.

While all that was happening, two identical beautiful women were waiting outside an office in a secret location. These women were Miya and Maya Yotsuba, and while their status was of great importance, they were made to wait outside the office until the person that was inside was ready to see them.

"I still don't like this." said Miya.

"We're only paying a visit to an old friend and having a little talk about the recent events in the magical world. If some of those events happen to be related to the Emiya Clan, all the better." was Maya's answer.

"Still, having to talk about this with that man is something that doesn't make me feel comfortable." was Miya's reply.

"Unfortunately, this is something that we have to do. The way that the Emiya hid their information was very good, and at this point we don't have anything of value on them." added Maya.

Before her sister could say anything else, the door of the office opened and a butler called them.

"The master will see you now."

Without another word, the two sisters got into the office to talk with the only man that they believed would know anything about the slippery Emiya Clan.
