AN: This is a fanfic of Mahouka Koukou No Rettousei, but other characters from Naruto, Fate/ stay night, Magister Negi Magi or "Mondaiji tachi ga Isekai Kara Kuru So Desu Yo?" will make an appearance. I don't own any of them except for some relatives, who I will introduce as oc. Some canon characters might be a bit ooc, because I will use them in different roles.

Chapter 1

It was in the middle of the night and Hayama the head buttler of the Yotsuba family was standing in the huge backyard of the Yotsuba Main House, awaiting the arrival of an important guest of his mistress Yotsuba Maya.

The Yotsuba is one of the most powerful and most influencial houses in the Ten Master Clans. Bearing the number Four in their name, it is a family in which its mebers' lives are shrouded in secrecy. But their ever growing power and influence has caused other clans to be wary of their growth and status.

The Yotsuba Main House was a rather large building done in the style of a traditional Samurai residence, which was located in a mountain village that is not recorded on any map.

Despite its secrecy the guest Hayama was waiting for knew its location, because of his ties with the Yotsuba family, but the knowledge these ties would make the other clans even more afraid of the Yotsuba, therefore the meeting had to be kept secret.

Suddenly some leaves and dust were blown up and even if he could see nothing in front of him Hayama could tell that a jet plane was landing.

After a few seconds everything calmed down and Hayama could see a flicker in the air and the plane uncloaked and a ramp was lowered and two guards carrying asault rifles got off. After looking around for a moment one of them touched the right side of his helmet and a young man with light blond hair spiking downwards in all directions in all directions and a set of purple eyes decended.

"Welcome to the Yotsuba Main House Sakamaki Izayoi-sama." Hayama greeted the young man.

"I'm also glad to see you in good health Hayama-san. But let's lose no time. I'm sure Maya-dono is waiting for me."

"Of course. Maya-sama is waiting for you in her private chambers. Would you follow me please?"

Izayoi ordered his guards to wait for him and followed Hayama into the building.

When Hayama and Izayoi entered Maya's chambers she was sitting on a chair at a small round table with a cup of tea in her hands.

"Hello Izayoi-kun. It's always a pleasure to host my cute nephew in my humble home."

"Despite my grandmother being your late father's cousin, it seems quite a stretch to call me your nephew. But there is no point in denying that I have blood-ties to the Yotsuba family."

"Even if it's faint i can feel the blood and the power of the Yotsuba flowing through your veins. But I'm sure you didn't aks for this audiance just because you wanted to see your most favourite aunt."

"I've made a few discoveries in the last weeks, which could effect on the future of the Yotsuba family. Therefore I wanted to aks you a few questions and discuss the issue with you. I will start with the questions I have, shall I?"

"If you think it concerns the futue of the clan I'm willing to answer you questions, but would you like a cup of tea first?"

"Gladly. Your tea is always the best Maya-dono."

After taking a few sips of tea Izayoi put his cup on the table and started questioning Maya.

"Could it be that you have a son?"

Even if Maya and Hayama, who stood next to his mistress, didn't show it, they were taken aback.

"How could I have a son Izayoi-kun? You know exactly what happended to me in my youth."

"I know what happened ot you, since my family's information network informed your father about your wherabouts after the kidnapping. I also know that you are not able to give birth to a child anymore, after what they have done to your body. But thanks to modern medicine that's not necessary to have a child anymore. All you need is one ovum, the seed of a man and a host mother."

"How do think I could have gotten all these things my dear nephew." Maya asked sweetly.

"Well getting your own ovum is not complicated, getting the sperm of your former fiancé after the death of his first wife and before his second marriage shouldn't have been much of problem for you either and convincing your sister to be the host mother for you wouldn't have been so difficult either, since she felt guilty for what she had done to you." Izayoi concluded.

"I always thought you were too smart for your own good." Maya said before casting Meteor Stream and two crimson orbs appeared in the room, but before anything could happen the orbs vanished.

"I hope for you Maya-dono that your display of magic was just a joke, because it would be quite unpleasant for me if I had to end your existence." Izayoi stated while taking a sip of tea from his cup.

"Yes it was just a little prank on my part, but your power to neutralize all kinds of energy and magic is really scary." Maya sighed in defeat.

"How did you find out?" Maya asked curiously.

"For my personal shame I have to admit that I had should have realized much earlier if I had listened to my magic instead of my logic. My magic has been telling me for a long time that your nephew Tasuya or should I rather say your son Tatsuya and his sister or rather his cousin Miyuki weren't siblings. Otherwise my logic told me that they were siblings, because your sister Miya gave birth to both of them, but the bonds I could feel between them weren't as strong as those I would have expected between siblings. Even those between him and his parents were strange. On the ther hand Tatsuya's magic was so uncommon, therefore I have written these feelings off as an anomaly." Izayoi explained.

"What has changed your perception?" Maya asked.

"About one week before my request for this audiance. I was working undercover as an assistant diplomat for the Commonwealth. There I got the chance to meet your former fiancé Saegusa Koichi. When I shook his hand I got the same feeling I got when I shook Tatsuya's hand once. After that I could connect all the dots, which didn't make any sence in the past." Izayoi ended his deduction.

"What will you do with this knowledge?" Maya asked anxiously.

"For now I will keep it a secret, but if I think the right time has come for them to know the truth I will tell them. They have just started highschool. Therefore there is no need for them to know it at the moment. But then I've realized that Miyuki has changed her bahaviour towards Tatsuya completely. At first she didn't even treat him as her brother, but after what happened at Okinava she treats him as if he's her man. Perhaps her magic is telling her that being together with him is not as impossible as her logic does."

"Perhaps it does." Maya chuckled.

Then Izayoi stood up, went over to Maya, took her right hand and kissed the back it.

"I will take leave now. After confirming my suspicions I've no reason to stay any longer. Take care Maya-dono." With these last words Izayoi left the Mayas' chambers.

"I'm glad he is on our side. It would be disastrous for the clan if he became our enemy."

"Yes it would be Maya-sama, but Izayoi-sama was raised and trained to lead a nation in future. Therefore he will only fight if he thinks it's necessary. Otherwise he would have reacted differently when you tried to use your magic on him. This was quite a foolish approach for someone like you Maya-sama. Since Izayoi-sama is one of the few people, who can defeat Tatsuya-sama in a fair fight." Hayama commented and Maya could do nothing but agree.
