Chapter 0: Prologue
For the Yotsuba, Shiba Tatsuya, the stain of their family, was supposed to be predictable. His sole task is to protect the diamond of their clan, and the supposed next head of the family.
In the minds of the Yotsuba Branch Heads, that was Tatsuya's sole function.
That is why they were blindsided when Tatsuya disappeared for two weeks.
Even the 101 Independent Magic-Equipped Battalion did not know of his whereabouts
Tatsuya disappeared without a trace, shocking one Shiba Miyuki. His disappearance would have plunged said girl into depression if it were not for a written letter penned by Tatsuya, promising him that he will return after conducting some business that would allow Shiba Miya, their mother, to not perish from her condition.
His disappearance caused mass panic within the leadership of the Yotsuba, and the Branch Heads wanted to mobilize resources to track him down.
Unfortunately, the Head of the Family, one Yotsuba Maya, did not give her permission for their people to mobilize. She told them that if Tatsuya truly rebelled against them, he would have taken Miyuki with him. Considering that Miyuki was still under the care of the Yotsuba and he had written a letter assuring of his return, it would be a waste of resources to deploy people to find him.
The Branch Heads wanted to insists the need to find and retrieve Tatsuya, but Maya did not even want to entertain their urgent please. She merely dismissed them with a laugh, telling them that Tatsuya would never betray the Yotsuba.
Or at the very least, he would not betray her, Maya was very insisting of that claim, Miyuki, and his mother
The Branch Heads were surprised by Maya's faith towards Tatsuya, and try as they might, they were not able to mobilize anyone to track Tatsuya's current whereabouts.
Any attempt to do so discreetly organize a search and tracking party were met with Maya's interference.
One was met with Maya's ire and a bullet of light.
That certain conversation silence the Branch Heads.
Yotsuba Maya never gives the same warning twice.
So the Branch Heads waited for the return of their clan's shame.
It was a long two weeks.
When Tatsuya returned, the boy made his way to his bedridden mother, an unconscious blonde girl in his arms.
There were attempts to apprehend Tatsuya.
Said attempts were thwarted when magic constructs burst into life and subdued those who attempted to stop him.
The Branch heads were shocked by this display of magic. They were not aware that Tatsuya was capable of such feats. He summoned those construct without a CAD, without any mediums similar to those of Ancient Magic Practitioners, and without any effort.
When Tatsuya arrived in his mother's deathbed, he performed a magic that were equal parts miraculous and demonic.
(Scene Change)
'He looks so bored.' Maya thought as she suppressed her urged to cackle in glee.
Normally, Maya dislikes having family meetings. Those are pointless and jarring to get through, and she really dislikes dealing with members of her family in groups.
If Maya has an issue with her family, she will deal with them in a more personal matter.
They are easily manageable if they do not hide themselves in the guise of numbers.
But this, this is enjoyable.
"Are you listening to us, boy?!"
"Why should I listen to any of you? None of you matters."
Maya placed a hand on her lips to prevent herself from laughing at the dry retort Tatsuya gave Mitsugu.
It has been more than two weeks since Tatsuya 'convinced' her (i.e. by fucking her till she lost her voice and all the feelings that she has on her legs) to allow him to do a personal job in the USNA.
All things considered, Tatsuya succeeded in said job spectacularly.
STARS has been significantly crippled, with 80% of their fighting forces decimated and one their Strategic-Class Magician, the most powerful among them all, kidnapped.
Said Strategic Class Magician is more or less dead, though Maya would like to use the word 'refurbish'.
This magic that her son created is very interesting.
"YOU IMPUDENT BRAT!" MItsugu spat, a glare fixed on Tatsuya.
The moment the head of the Kuroba family shouted, a blade made out of spiritual particles appeared mere millimeters on Mitsugu's throat. The blade was close to Mitsugu's neck. So close in fact that the tip of the sword broke skin and cause a prickle of blood to flow down the Kuroba Family Head's neck.
This act startled the Branch Heads into silence.
They could not remember the last time Tatsuya lashed out at them
"Aside from Obaa-ue…" Maya disliked her son calling her by that pronoun, but she'll remedy that later. She was delighted with the small smile that her son gave her though. That was a pleasant change to their relationship. "…can any of you kill me?"
That questioned stunned the clan heads.
"Let me rephrase that, aside from our honorable Clan Head, who among you here has a chance against me in combat?" Tatsuya paused as he eyed every single Branch Heads of the Yotsuba.
No one spoke.
Maya smiled at their silence.
She enjoyed watching her son flaunt his power.
"Only our dear Clan Head has the right and authority to demand answers from me…" Maya shivered in delight at the sound of her son calling her 'dear'. "What right do any of you have to demand an explanation from me?" Tatsuya challenged as he eyed every single one in the room.
Everyone but Maya, but said woman did not mind. She will have an intimate, one-on-one conversation with her son. If said conversation includes a bed and mountains of pleasure crashing down upon her, so be it.
Shibata Osamu, with fear and anger in his eyes, snarled at Tatsuya. "YOU DARE SPEAK TO US LIKE…"
Osamu was silence when a massive claw manifested around Tatsuya and gripped him his entire body but his head in a tight hold.
Osamu grasped for breath as said hand held him to the point that it squeeze the air out of his lungs.
This made every single Branch Head, but Mitsugu to prepare their CADs to fight Tatsuya, but human shape spiritual constructs appeared behind them, hands on their CADs, and sharped claws upon their necks.
The only one untouched was Maya.
"Let us not make a mess in front of Oba-eu, shall we?" Tatsuya stated, his normally apathetic voice lace with sarcasm. "And let us all be honest, none of you has a chance against me anyways." Tatsuya added dismissively.
With the Branch Heads neutralized, Tatsuya turned his attention to Maya.
Maya gleefully enjoyed her son's entire attention focused solely on her.
"Would you accept a summary of my endeavors for the past week?" Tatsuya asked, voice actually respectful.
Tatsuya already told her of the specifics of his two weeks incursion in the USNA, but Maya, for the sake of those around her, though it was more to hear her son speak, nodded at him to speak.
"I developed a magic to extend Shiba Miya's life. Said magic involves transferring her soul, spirit and consciousness from her frail body to an able, healthier body. The body that I choose for my mother to occupy is the body of one Angelina Kudou Shields, also known as the USNA's current Sirius. Acquiring the body of one Angelina Kudou Shields would not just weaken the military might of USNA, it would also provide my mother, who had contributed greatly in the coffers of this family as well as its magical development, a longer and more convenient life than she original had with her failing constitution. During my endeavor in the USNA, I made sure no one saw me, and every hostile that I fought, I made sure they didn't survive me. No one saw me entering USNA, no one saw me when I was in the USNA, and no one saw me procuring Shields-san and leaving the USNA." Tatsuya informed those around him, his eyes leveled only to Maya. "And if they had seen me and if they attempted harm upon the Yotsuba, I promised you, I will erase the entirety of the USNA from the globe." Tatsuya promised, eyes leveled upon Maya.
Maya shuddered delightfully at the intense looked that her son was giving her.
They will be having so much fun after this little affair has been settle.
For now, business.
"I would require a more extensive explanation later, but for now, that will do." Maya stated before motioning towards her cousins. "Can you recall your familiars?" Maya ordered, though her tone of voice indicated to Tatsuya that it was a request.
"They attack me, I will send them to their children in urns." Tatsuya warned as the familiars that he summoned disappeared in a wisp of silver.
The sword on Mitsugu's throat and the demonic hand that was slowly crushing Osamu's person disappeared as well.
Without turning his gazed the Branch Heads, Tatsuya spoke again. "Would you all like to try again?" Tatsuya challenged, his voice uninterested and bored.
The Branch heads could only stare at Tatsuya.
At that very moment, he looked every bit like Maya, much to the Branch Heads' dread and Maya's delight.
The ensuing silence from the Branch Heads was a resounding no.
With his annoyance momentarily taken care of, Tatsuya walked towards Maya, and to the surprised of those around him, he grabbed Maya's hand and gently kissed her knuckles.
Even Maya was taken aback by this gesture.
"If the USNA give you grief, tell me, I will take care of it." Tatsuya promised Maya before leaning forward and kissing her on the cheeks.
Letting go of her hand, Tatsuya gave the gawking Branch Heads a flat look. "What?!" Tatsuya drawled challengingly. "I can't give my own aunt any affection! What do you think of me, an animal?"
With that piece said, Tatsuya made his exit out of the room.
He was very much aware that Maya was giving him a lustful and hungry looked.
No worries. He would sate her later.
For now, there are other pressing issues to take care of.
(Scene Change)
Shiba Miyuki wanted to be angry with her Onii-sama. She really wanted to be upset with him.
His disappearance almost caused her a heart attack, and for an entirety of two weeks, regardless of his assurance that he will return to her, she was worried that he was going to abandoned her.
Considering how she treated him in the early days of their life, Miyuki could not really blame him.
Of course, her worries were for naught as her brother returned, a girl in her arms.
Originally, Miyuki was very upset and angry at the sight of her Onii-sama carrying a blonde hussy in his arms, but after a brief explanation on why the girl was a necessity and after a quick summary of the magic that would prevent their mother from dying, Miyuki calmed down and allowed her brother to attempt a miracle.
A miracle was achieved.
Her mother would live.
Although, not in a way that was expected, or preferable for the Shiba Matriarch.
"I never expected him to hide such capabilities." Shiba Miya grumbled, half irritated, half impressed as she looked over the magic that effectively extended her life.
The Outer-Systematic Type Magic, [Ego Transfer], a magic that transfer the soul and subconscious of an individual from one body to another.
In this case, Tatsuya transfer her soul and subconscious from her dying body to the body of one Angelina Kudou Shields.
Momentarily looking at the mirror, Miya cringed at the sight of her.
Instead of black hair, she now saw blonde. Instead of pure Japanese features, her features are now mix with Easter and Western characteristics. Instead of a mature body, she now saw a body that was in the cups of its development.
Miya was somewhat relieved that her voice was similar to her voice when she was a child and that her eyes are still red.
An aftereffect of the Magic Tatsuya used to 'extend' her life.
"Are you still upset with Onii-sama, Okaa-sama?" Miyuki asked as she stood a few feet from her mother.
Miyuki was still trying to comprehend her mother's current situation, but she was relieved that her mother would not yet leave her, even if she was no longer in a body that she was accustomed to.
"Tatsuya-san should not have bothered." Miya stated while sparing her daughter a glance. It was strange to not physical look down on her. Right now, they were of the same size. "If the USNA found out of what he did, it would be war." Miya commented, shuddering at the thought.
"It would be a short war." A familiar male voice stated as one Shiba Tatsuya stepped into the room by phasing through a war.
Another oversight by Miya. She failed to comprehend what her son is fully capable of. A third magic that he hid for years, a more comprehensive control over his two existing magic, and a developing personality that was too close to Maya's for Miya's comfort.
Miya watched as Tatsuya walked close to Miyuki. He wrapped an arm around her and gingerly kissed her on the cheek. The show of affection made her daughter blushed bright red.
For now, Miya ignored this.
There were other pressing issues that needs to be address.
"Are you so arrogant that you believed that you can triumph over the full might of the USNA army?" Miya asked and scolded her son.
"Yes." Tatsuya answered without hesitation. "Would you like me to go back to the USNA, and bring you every head of their army's generals? Or would you prefer the head of every Congressperson or Senators? Or would you like the head of their current sitting President and his entire cabinet? Just say the word." Tatsuya offered, his confidence, for the first time that Miya and Miyuki could recall, was clearly shown.
It appears that his third magic had truly develop a personality within Tatsuya.
"Are you afraid that what I did would cost your family to go into a war that they could not win?" Tatsuya asked, eyes of the crimson eyes of his mother. "Banish such thoughts from your mind, Mother. I will admit to you that I do not care much for this family, but for Miyuki, I will destroy this world, and for you and Obaa-eu, I will at least fight and win wars for both of you. I will even destroy countries for both of you." Tatsuya assured his mother.
That admission startled Miya and delighted Miyuki.
"That made it sound that you care for me." Miya said in disbelief.
"A not so insignificant part of me values you, and that value is beyond what you are to Miyuki, though not that match." Tatsuya told her. "You are the third being in this world that I value. This little Princess would always be my priority…" Tatsuya tighten his gripped on Miyuki before laying a kiss on the crown of her head. Again, Miyuki blushed at how affectionate her brother has become, though she was not complaining, and was already wondering how much affection she could get from him. "…Obaa-eu would be second, you are a close third." Tatsuya admitted.
Setting aside the fact that Tatsuya seemingly has the ability to value people outside of Miyuki, something to look at later, Miya unconsciously focused onto an issue that irked her.
"You value Maya over me." Miya did not know whether to be insulted or outraged by that fact.
Tatsuya only raised a brow at him. "To me, Obaa-eu is much more interesting than you." Tatsuya answered his mother with a casual tone. "But if you want me to value you more over her, then let us get to know each other. Let us renew our relationship, improved it to what we had before." Tatsuya offered genuinely.
At that moment, Miyuki could not be happier.
Miya, as well, could not be more shock.
"So what do you say, shall we start a new?"
(Scene Change)
After recovering from her first experience with Tatsuya, now with a dash of personality, Miya made her way to her sister's chambers.
Miya ignored the stares that she was getting from the servants.
It appears that her new 'living' situation was now common knowledge to the people employed by the family.
Arriving and entering the chambers of her twin, former, Miya immediately ask the question that has been bugging her since her entirety was transferred to the body of Angelina Kudou Shields.
"Why did you allow Tatsuya-san to preserve me?"
That question delighted Maya, and she showed her elder sister the video of the night she gave Tatsuya the blessing to go forward with his intentions.
Setting aside Tatsuya attacking the main residence, setting aside Tatsuya's interest having relations that is beyond that of a siblings with Miyuki, which is what she intended when she created her daughter (at least that part of the plan was going forward nicely), Miya felt a bit of warmth spread through her at the verbal and video admission that her son values her, enough to even destroy USNA.
It was concerning that her son would wage a World War for Maya, but that can be address later.
As much as it was pleasing to know that her son loves her in some shape, Miya did not enjoy seeing what her son did to get the approval of her sister.
"You raped my son!" Miya shouted in rage, a spark of lightning crackling around her.
"I did not." Maya denied, sound outraged, though there was a touch of amusement in her voice. "As you could see in said video, it was consensual and he was very eager to convince me to approve of his mission." Maya purred delightfully as she watched her son fuck her through the table. "Very eager~"
The video screen suddenly vanished, the terminal showing the coupling of her son and sister short circuiting due to magic oozing out of Miya's new body.
Maya gave her sister a disapproving stare. She was enjoying watching herself get fucked by her son. "Now sister, that is immature of you." Maya scolded her older sister before enveloping the room with her Zone Interference.
That immediately suppressed Miya's excess Magic.
"You should really start relearning how to use your magic, Nee-san. The body that Tatsuya-kun gifted you has more magical potential that your previous one. It would be a waste if you didn't know how to properly use it." Maya chided her sister. "And considering you're here, would you like to discuss which lingerieTatsuya-kun would enjoy ripping off my body."
"You raped my son!" Miya repeated herself, angrier than before.
Maya rolled her eyes at her sister's outraged. "It was consensual, and I am not the only one who enjoyed the coupling." A lascivious smile crossed Maya's lips. "In fact, considering how many times he finished in my pussy, ass, and mouth, I think he enjoyed our coupling more than me."
10 in the cunt, seven in the ass, four in the mouth, that night was the most glorious night of her life, and she was very eager for a repeat.
Repressing the urged to choke her sister to the death, Miya snarled at her sister. "Have you forgotten of our plans for my son?"
"I have not." Maya answered, annoyed that her sister was still continuing to claim her son as hers. Her sister was now in a body of a 13 year old girl. She was more unqualified to be her son's mother more than the time she was still occupying her dying husk of a body. "Tatsuya-kun and Miyuki-san would be husband and wife. That part of the scheme will never change." Maya assured, but the smile on her lips did not give Miya any comfort.
"The only addition to the plan is that I will be his second bride." Maya announced gleefully.
Miya gave Maya a flat, murderous stare.
"You think you are the only one who deserves a new lease in life?" Maya asked rhetorically.
"That magic is an abomination." Miya stated strongly.
"I agree, and I will have all traces of that magic expunge from our records, but not before I get myself a new, fertile body for Tatsuya-kun to plow and impregnate." Maya told her sister, a psychotic edge in her voice. "If it means anything, my new body is currently being made from the ground up by yours truly. We will not be abducting a girl from an affluent clan or country."
Maya was tempted to arrange a kidnapping for one Saegusa Mayumi, but decided against it in the last minute.
She could do better than the daughter of her former flame.
"That is not the point!" Miya snapped at her sister.
"Considering what Fate had given us, we deserved new lives and the magic that my son created is going to give us those lives." Maya shot back. "I will not deny myself the happiness of having children of my own, with a husband that will protect me!" Maya shouted, eyes clouded with happiness that she knew Tatsuya would give her, and anger of her sister's blindness and selfishness.
"And if you are worried that Miyuki-san would not agree of having me as her sister-wife, don't." Maya said mockingly. "I could be very convincing, and Miyuki-san is pretty enough for me to have her in my bed."
Miya could only glare at her sister, hand clenched tightly.
It appears that she still has to deal with her twin's craziness even with this new body.
