A rewrite of an old project of mine.

Also, one of the last two new stories that I'll work on here before migrating to AO3.

Anyways, enjoy.


The Darkness.

The Void.

The Unknown.

The Shadows.

And the list could go on as what Shirou was feeling. The last thing he remembered was using a copy of Excalibur to destroy the Grail, as well as the cries of Illyasviel who wanted to sacrifice herself.

"Illya… Rin… Sakura…" the boy muttered as he was drifting in the nothingness.

Do you feel… lonely? a voice asked.

"Who is here?" Shirou asked with an empty voice.

Do you wish to have a family? the voice asked again Do you wish to get a life where there's no Grail war? ... A life where you can live with a family?

"A family…" Shirou remembered his father Kiritsugu, his childhood friend and teacher Taiga, even the moment he passed with Illya "A… family"

What an interesting person you are… But that won't do… you need to be full of life… the voice stated Listen… human… I'm going to need a body to recuperate my strength… a host who can keep me safe…

Shirou said nothing as his mind wasn't fixated on anything.

I know of your powers… its limits… and it intrigued me… Shirou was grabbed by a dark purple tentacle in the left arm You shall be reborn… a new life awaits you… however… you won't have the memory of your old life… Shirou's eyes went wide as he began to forget everything Once I feel that you're ready and strong enough… you will get them back… the last memories of Shirou faded away as he was being pulled toward a large amassment of smoke with many tentacles around it as well as many eyes glowing You shall become the herald of my strength… but be warned… if some of the others came to feel you as my host… you need to be ready to fight… the smoke began to enter Shirou until it disappeared into his body.

This is going to be interesting…


In a hospital in Kuoh, a young couple got two children.

"Look at them" the mother said "They are so adorable"

"I didn't knew that we would have twins" the father said as he looked at the two "How should we call them?"

"I was thinking of calling the boy Shirou and the girl Sei" the mother replied as she looked at the two twins they got.

"That sounds like a plan I would be fine with" the father said.


*Seventeen years later*

Shirou awoke as his alarm clock rang. He opened his eyes before shutting the alarm clock with his right hand, but when he tried to move his left one, he found it trapped.

'Not again…' Shirou groaned mentally before looking at his left only to look away immediately 'How did she opened the door after that I locked it away before sleeping!'

His left arm was currently trapped by a busty brown haired girl that's sleeping naked next to him. He freed his arm before exiting his room, he had to figure a way to deal with this problem that he has. He made his way toward the kitchen.

"Good morning" he greeted when entering the kitchen.

"Good morning, Shirou-kun" a woman with tied long brown hair said as she turned toward him "How did you slept?"

"You know what happened, right?" he asked, feeling some irritation that grew a bit more when he received a giggle as answer "You know that you should have stopped her, mom"

"Aw, don't be hard on her" she replied "She told me that she couldn't sleep"

Shirou just sighed before asking "Anyways, do you need help to prepare breakfast?"

"Don't worry about it" his mother said "But if you want to help, why don't you try to made the lunches for you and your sister"

Shirou nodded before beginning to do the task. At the same moment, a familiar girl entered the kitchen fully dressed in her school uniform "Good morning…" she said while rubbing her left eye.

"Good morning Sei" Replied her mother.

"Good morning…" mumbled Shirou with a low voice.

Sei grinned before sneaking behind Shirou, as she was about to jump on him, he turned and gave her a flat look, but a scary one "You know how I feel when I'm bothered when I'm in the kitchen, right?" Sei nodded "And I don't need to remind you of the cause of the reason why I haven't changed in my school uniform, right?" another nod "Then you understand that I don't have time to play games, right?" After the third nod, Shirou turned back and continued to make the lunches.

"Is there something I can do to… redeem myself?" she asked sheepishly while scratching the back of her head.

After a moment, Shirou said "I'll think of something"

Sei smiled and gave Shirou a thumb up "Don't worry Oni-chan, I'll redeem myself"

Shirou could only sigh as he packed both lunches "Don't forget your lunch" he said while giving Sei her lunch "I'll go change my cloths"

"Don't take too much time" their mother said "Or I'll send your sister to check up on you"

Shirou turned and gave her an annoyed look as he said "You know that I don't take long"

"Who knows what could happen to you" the woman replied, still smiling "Just kidding"

"What kind of joke is that?" asked Shirou with a sweatdrop before heading to his room to change his cloths.


After a couple of minutes, both Shirou and Sei exited their home only to encounter a girl in their school uniform. She had long Bronze colored hair and hazel colored eyes.

"Good morning, Yayoi-san" Shirou replied with a smile.

"Morning, Aoki-chan!" Sei Greeted with a cheerful tone.

"Good morning, Shirou-kun, Sei-chan" the girl, Aoki Yayoi, said as she greeted the siblings

"You didn't waited for too long, right?" Shirou asked.

"I just arrived" the girl replied "I thought that you were going to take longer"

"That could have happened…" Shirou stated as he stared at his sister, who chuckled nervously as she scratched the back of her head.

As they were walking, Sei couldn't help but smug as she looked at Shirou.

"Say, Oni-chan, do you like big breats?" she asked.

Shirou stopped, and looked at his sister. He said nothing as he hit Sei on the head "Stop being so perverted"

"You didn't had to hit so hard!" his sister cried as she held her head.

"You never change…" Aoki commented with a sweatdrop.

"Let's just continue" Shirou sighed as he continued to walk "I don't want to be late"

"Oni-chan is so strict" Sei stated before getting a smug "You'll never get a girlfriend that way"

"Sei" Shirou called as he grabbed her head "Don't push the buttons you shouldn't push"


After a long walk, the three students entered through the school gate as the other students began to whisper around them with the girls being envious of Sei's closeness to Shirou, while the boys are jealous of Shirou always walking with two girls.

"Shirou-sama… I really want to be your wife" mumbled a girl dreamily.

"He's so dreamy" another girl squealed.

"I would give anything to have the possibility to wake up every morning to someone like him"

On the other hand, the boys weren't so happy to see him.

"Tch, he had to come"

"I bet that I can beat him easily"

"Why the hell is he still walking with these two hotties!"

Shirou could just sigh as he felt a headache, he then got a feeling to duck to evade a punch.

"Good morning you bastard!" yelled his aggressor.

"Good morning Mastuda" replied Shirou as he smiled to the bald boy named Matsuda, he then turned to one wearing glasses "Good morning, Motohama"

"Shirou Hyoudou" said Motohama "I could say good morning, but you still refuse to accept our proposal of alliance"

Shirou shook his head before saying "I told you that I'm not interested in what you guys do. I just want to have a good year, without any problem with the faculty members"

"Traitor!" Matsuda yelled before pointing Shirou "We need you to get a chance with a girl!"

"Do I look like I'm interested in your perverted hobbies?" deadpanned Shirou "Why don't you go try your chance with another perverted guy in this school"

Both Matsuda and Motohama gasped, but it was Motohama who talked "Do you expect us to find someone who's popular with many girls in this school just by snapping our fingers? No, no, no, it doesn't work like that" he then brought shirou toward him before asking "What about you hot twin sis, is she free or no?"

"Motohama…" called Shirou with a smile before punching the teen in the guts, rendering him unconscious "Don't you ever ask me that again… understood?" he then walked away as both Sei and Aoki followed him.

"You do care about her" Aoki commented with a smile.

"Of course that I care about her" Shirou replied "I just try to make sure that she behaves in public"

"What a great big brother you are" Aoki said.

"I'm not her big brother, but her twin brother" Shirou stated "I'm only bigger by some minutes"

"That still makes you as her big brother" Aoki said with a giggle.

"I don't want it to be like this" Shirou sighed before adding "I'm not superior to her"

Somewhere else, a red haired girl watched Shirou and the two girls walking to their classroom.

"Sei Hyoudou, I know that you have a Sacred Gear" she mumbled.

"Rias" a black haired girl approached the red haired one "We're going to be late"

"I know that she possesses a Sacred Gear" Rias said as she eyed the younger twin "I'm going to need to find what kind of Sacred Gear it is"

"It seems like you're going to get a little personal with them" the black haired girl said with a giggle "Besides, I wouldn't mind getting someone like Shirou in the package"

"Maybe that I should ask Koneko to keep an eye on them" Rias mumbled before turning to head to her classroom "Let's go, Akeno, we will think more about it later"


This time, it's going to be my own rules.

And yes, Shirou will have a harem.

Don't like it? Too bad, this is a Shirou story.

If you're interested, stay tuned for the next chapter.
