Episode 1: The Beginning of a New Life
(Reincarnated Seraph)
Random Hospital
"Ugh here you go Matou-san." The receptionist at the desk said nervously as he handed a bag to a man.
The man's appearance or more specifically his eyes are quite exotic especially in Japan. The men's medium length black hair that can be considered neat and messy at the same, but still goes with his appearance. His sharp green eyes under thick eyebrows giving him a fierce look.
The man turned toward the receptionist confused before taking the bag. "Ah, thank you." He said and walked out.
When he reached a few yards away from the hospital, he turned around glaring lightly at the building.
"Who the hell is Matou-san?"
Apartment
Walking up to his apartment the man checked his mailbox, which contained dozens of envelopes. Opening the door he plopped down onto couch and sifted through them. All of them are addressed to the same person.
Kariya Matou.
Kariya Matou.
Kariya Matou.
Kariya Matou.
Jumping up from the couch the man's face held a snarl.
"Ah! My names not Kariya Matou it's Yuichiro Hyakuya damn it!" Yuichiro or Yu yelled and as soon as the words left his mouth he looked around calmly. His face held no emotion, he just looked around taking in his surroundings. His calmness soon turned into panic as he rushed towards the window and looked outside.
Outside looked..normal and totally not destroyed, which is weird since he has become used to the desolate wasteland the Earth had become after the adults had perished eight-years ago. So seeing everything fine and normal gave him a rather good feeling. But his 'happy feelings' were interrupted when he realized absurdity of the outside being completely fixed. He was stunned before he remembered something vital.
Kariya Matou
'Who the hell is Kariya Matou?' The thoughts rang through Yu's head, he then walks through the apartment towards the bathroom not even questioning on how he knows where the bathroom is.
When he entered the bathroom his attention was focused on the mirror.
'Nothing looks different.' Yu's deduction is correct he looks exactly the same. Same thick eyebrows, same green eyes, same messy hair, and same facial structure. So why are people calling him Kariya Matou.
Even with Yu's limited education he came to a solution rather quickly and walks back to the living room and picked up the bag from the hospital and opened it. Inside the bag is a wallet, Yu don't know why the wallet is in there but he doesn't really care right now.
He looked inside the wallet and looked at the I.D belonging to Kariya Matou. The pictured showed a young man with dark hair and eyes. Putting down the wallet, Yu contemplated his current situation.
He had somehow someway taken some dude's body along with life. Ugh! This doesn't make any sense. Something like body stealing should be impossible! Even if it is how is he going to deal with the repercussions of this. This gu- Kariya probably had family somewhere worried sick for him.
'You really shouldn't worry too much, Yu.' A voice resonated within Yu's mind.
That voice, it's familiar sound causing Yu to relax. He finally had a familiar face to talk. How can he not be familiar with the voice. After all it belongs to the demon within his Cursed Gear Asuramaru.
'Ashera. Do you have an explanation for this? And if you're here does that mean _ is here too.' He mentally asked the vampire-turned-demon.
Ashera sighed at the question and Yu was almost sure he is likely massaging his head, to calm the growing headache.
' I do have an explanation for why we're here but it doesn't seem like he came with us.' The demon's toned clearly showed her satisfaction at not having to deal with him.
'Damn so I have to deal with you by myself now.' Yu grumbled to himself, not liking the idea of being with Ashera without _ there.
Hey, you should be happy we now get some quality time together.' Ashera said the words whimsically.
'Damn it! Just tell me what happened my memories are a jumbled mess right now.' He practically yelled at the boy who just puffed his cheeks in an uncharacteristic pout before answering.
'It's actually quite simple, you overused your Seraph Mode and the angels attempted to take your soul. But _ and I didn't want that to happen so we interfered with the process. You being sent into a new body must have been the backlash of our decision. As of right now i'm bound to your soul so were stuck together.'
'But who is Kariya Matou and where is his soul?' Yu asked generally worried, he didn't exactly snatching someone else's body.
'Oh..him well he perished from his wounds after getting hit by a speeding car. Your soul took the initiative and a soon as his departed from the body, your's took it's place.' Ashera said the words so nonchalantly that Yu's mouth gaped open.
"W-what?" He muttered in shock, the reaction spurning some words from Ashera.
'Why did you think you woke up in hospital?' He said as if he was talking about the weather.
Still in shock at his predicament and the fact Ashera is acting like nothing has happened, Yu regained his composure and continued.
'And what about _? Also how come I didn't freak out as soon as I woke?'
Ashera hummed in contemplation before 'turning' towards Yu.
'Well I know for sure _ isn't here and I have no clue why he isn't. And as for your other question, I used my limited control over your mind to keep you calm. Couldn't exactly have you freaking out in public you know, we have an image to maintain.' Again Ashera's nonchalant manner shocked Yu. How can he be so calm when he has been reincarnated into another body after having his soul almost taken and are now within another fucking universe. And being in another universe is the only explanation Yu has since everything seems to be fixed. Or maybe he's in the distant past or the far future, he doesn't know.
'You are right we are in another universe, or more specifically were in _'s universe.' Again he says it so simply, but Yu just sighed and massaged his forehead. He was already surprised enough for the day. Nothing can really faze him much now.
'Well, does Kariya Matou have any family or friends?' Yu asked wanting to know just incase. Ashera 'looked' up humming.
'Yea in Fuyuki City.' Yu just narrowed his eyes at the information catching Ashera's curiosity.
'You're not thinking of actually going. What purpose would traveling to some cit help you?' Ashera asked while giving him the 'you're an idiot look.'
'What I can't just take a guy's body and just move on with my life like nothing happened.' His thoughts causing Ashera to sigh.
'Kariya Matou is dead Yu and you have no obligation to involve yourself with his former associates. You shouldn't feel bad, fate just dealt Kariya a bad hand in life and gave you good one allowing you to live a second one. Live it to the fullest.' Ashera's words while indeed correct are not something Yu wants to hear.
'I know.'
'And yet you're still going.'
'Yes.'
Nameless Park
Few Days Later
Getting to Fuyuki had been an interesting ordeal. Since Yu is in an 'alternate universe,' with no knowledge of the world and it's workings. He had to rely on Ashera to guide him using Kariya's memories. So it took him a few days when only should have been a few hours based on this world's map of Japan.
Yu is currently standing within a random park just watching the kids playing and socializing.
It..is a weird experience for Yu, his world had been in ruin most of his life. So seeing everything so peaceful and serene it gave Yu a good feeling. While also at the same time it made him somewhat jealous and resentful of them. Why couldn't his life be just like theirs? Normal. But Yu understands that being jealous and resentful of some random kids because of his own shitty life isn't exactly fair to them.
Yu's attention shifted to his real target. According to Kariya's memories a certain love interest of his often comes here with her children. His gaze soon found a woman with dark green hair and dark eyes wearing a light green dress with a white scarf.
Aoi Tohsaka the child friend of Kariya along with his long time crush. The woman is married to a magus by the name Tokiomi Tohsaka. She has two children Sakura and Rin Tohsaka.
Yu scanned the park again and came upon the small frame of Rin Tohsaka. Her brown hair flying through the air as she ran and her blue eyes shining with happiness. He looked again and frowned. Where is Sakura? Usually she would standing right beside Aoi, usually conversing with her mother instead of playing with other children.
Yu narrowed his eyes, he didn't like the feeling he was getting from the situation. Even then he didn't let it control him. Maybe Sakura is just sick with a fever or a cold or something.
Silently Yu turned and left the park, next stop
Matou Manor.
Matou Manor, Zouken's Study
Sometime Between 30-40 Minutes Later
"I'm surprised you came back Kariya." The aged voice of Zouken Matou stated impassively. Yu stood before him, his mouth set into a thin line.
The….human(?) before him just screamed 'danger' and his instincts are telling him to be 'cautious' around the old man. Which is something Yu took to heart since his instincts has saved his life numerous times. They're also telling him this thing isn't human, and Yu can atest to that due to amount of time he spends in the presence of inhuman beings, Ashera and _ being two examples. He can tell Zouken isn't human but also human at the same, a contradiction that his trusted instincts can't tell which is which. The fact putting Yu even more on guard than before.
"Well I decided to visit, I figured you were getting lonely without me." Kariya's voice came from Yu's mouth which held a smirk. Zouken just scoffed at the notion of him actually missing Kariya.
"Please, just because you had a sudden change of appearance doesn't mean you're any more of a failure Kariya." Zouken's words just caused Yu to smirk wider, who can easily tell the aged man is annoyed.
"Well this failure happens to be the last candidate for the Matou magecraft." Yu doesn't know why he is taking so much pleasure in mocking the old man. It's probably some form of payback for actually tricking his prided instincts.
"Not exactly." Zouken's face held a shit-eating grin, and Yu's faced showed his surprise. Zouken decided to just take action and show Kariya.
"Come, let me show you."
Same Place
Half an Hour Later
Back in Zouken's study, Yu's face held a snarl.
To think...to think that bastard would subject a little girl like Sakura to those accursed….monstrosities. Yu was extremely tempted to pull out Asuramaru and sliced the man to pieces. Yu may have never killed humans before but he's willing to make an exception. Even though Yu has no emotional attachment, what he saw pissed him off. Plus the fact Kariya had an emotional attachment and the fillings hit Yu hard when Ashera went through his memories.
"I can't believe you would subject a girl to that... that torture!" Yu's voice clearly showed his anger. And it was Zouken's turn to smirk.
"Well you see Kariya, I was backed into a corner. With no one to pass on the Matou bloodline, I needed to at least pass on our magecraft. So the Tohsaka's were kind enough to give a suitable heir who has a ton of potential." Zouken's voice clearly showed why he was smirking. He thought he had won! Bastard!
"What will it take you to stop her training?" Yu asked and his question seem to have caught the attention of Zouken. Who hummed in thought, clearly stalling just to annoy him.
"Oh I don't know how about a certain wish-granting Holy Grail." Zouken's smirk widened into that of a madman.
"You want me to fight in the Holy Grail War don't you?" Yu asked the obvious, Kariya's knowledge of the war filtering into his mind from Ashera.
"It's not as if I expect you to actually win. I mean considering your lack of training as a magus."
Silence dawned on the office, the two occupants having a stare down.
"I want full access to the Matou resources." Yu's voice resonated and Zouken's mouth gaped open.
"Wha-what! Do you think i'm going to allow a failure suc-." Zouken's yell was cut off by Yu's firm but calm voice.
"If you want me to win the Holy Grail War then i'm going to need to prepare myself. Without the resources of the Matou family I won't even be able to compete with the other Master. Even with a strong Servant i'll be the weak link." Yu's eyes held a strong conviction. Even though he has no desire for the Grail, he will fight in it to free Sakura.
Because that is what Kariya would do.
"Fine! Start preparing then." Zouken said resolutely, wanting to see Kariya fail even after trying. And he will take great pleasure in watching.
Yu nodded and started walking out of the office but stopped at the door. He turned to Zouken his face showing his sour mood. Kariya's memories may still be around but he is dead and he can't go around pretending to be him. He can't just use his identity like that.
"Zouken I would like if you would stopped calling me by Kariya Matou, instead call me Yuichiro Hyakuya.
And he walked out.
Basement of the Matou Manor
One Year Later
The basement of the Matou Manor is clear of any of these wretched worms, a magic circle for the Summoning Ritual already made. Yu looked at the paper in his hand with the chant on it and memorised it quickly, a skill he picked up over the year. The ritual is surprisingly simple for summoning something like a Heroic Spirit but the Grail is doing the actual summoning. All he has to do is feed the Servant mana to keep anchored here.
He put the paper away and looked at the piece of wood Zouken had given him. It is supposedly a piece of the Round Table. A catalyst that would definitely summon a strong Servant. He threw it away, just summoning a Servant without a catalyst would give him one he is most compatible with. Yu took a deep breath, readying himself.
"Die." An aria left Yu's lips, one used to activate his magic circuits, most magi wouldn't need an aria just to activate circuits but since Yu has only been practicing for a year. Using an aria is just easier and faster than without one. But the aria is definitely appropriate, for a word that gives Yu power it makes sense.
Death has always been a constant in Yuichiro Hyakuya life, the adults of his world dieing to a strange virus. The deaths of the Byakuya orphans at the hands of Ferid and the amount vampires Yu himself has killed. And after each and everything death around him Yuichiro came out stronger and better.
He has to compete in this war, for Sakura and Kariya's sake. He had taken Kariya's body from him, he may have died but it still left a bad feeling in his mouth. Kariya had given him a second chance of life and he has to live up to that sacrifice. Even though Ashera keeps telling him he doesn't have to take so far.
Yu took another deep breath and chanted.
Fill, fill, fill, fill, fill!
Repeat five times.
But when each is filled, destroy it.
His circuit seems to heat up slightly as the ritual started.
For the elements silver and iron.
For the foundation, stone and the Archduke of Pacts.
And for my ancestor, my great master, Schweinorg.
Raise a wall the block the falling wind.
Close the gates of the four directions.
Come forth from the Crown and follow the forked road leading to the Kingdom.
The circle started glowing and mana surged through Yu's circuits.
Heed my words.
My will creates your body, and your sword creates my destiny.
If you heed the Grail's call and obey my will and reason, then answer me!
I hereby swear….
That I shall be all the good in the world.
That I shall defeat all evil in the world.
The circle glowed brightly and Yu grit his teeth as the pain of mana surging through circuits hit him. The amount of power the ritual requires is taxing on someone with underdeveloped circuits like him.
The rituals power flared around creating imaginary wind.
Thou Seventh Heaven, clad in three great words of power, come forth from the circle of binding, Guardian of the Scales. (1)
Yu's vision turned into a sea of blue as the mana of the circle was dispersed. Yu blinked as smoke covered the circle block Yu's vision of his Servant. But he can feel the connection of mana between them.
"You should be proud for having summoned me." A female voice emanated from within the smoke.
When it cleared the voice came from a girl wearing vibrant green with long unkempt blonde hair that ends with green. Green eyes like his but held a wild and beastly glint to them, as if the owner were a beast instead of human. The appearance was finished with a pair cat ears on her head and a cat tail.
The woman looked at him and gave a savage grin. Like a predator had caught it's prey and was about to devour it.
"For you have brought forth Servant Archer, and I ask you
Are you my Master?
End
Boom, the first ever Seraph of the End and Fate/Stay Night Fanfiction b*tches! F*CK YEAH i'm being innovative.
First, i'm sorry to those who read my other stories but they are currently on hiatus (except for Uzumaki Legacy) as I catch up with stuff IRL, i've also gotten hit with a small case of writer's block. I really wrote this just to be innovative.
Second the Yu that was reincarnated is different from canon, he is a fanfiction created Yu. Before planning this story, I had wanted to try something else for the FIRST SERAPH OF THE END AND FATE/STAY NIGHT CROSSOVER FANFICTION! But I scrapped the idea temporarily for this and it might end up becoming a prequel to this story. Yu's relationship with _ will be explained then. But I didn't tell you because that would be a spoiler for the prequel (if I decide to do it).
If you help on exactly when Yu died, it's the end of Season 1 where Yu goes Seraph on Mirai. The angels took his soul as punishment for using his seraph abilities.
Also I know I bended some Nasu-verse and Seraph-verse rules but who cares, it's fanfiction. The motto of the website is "unleash your imagination." This fic is also practice for any future Fate fics I have planned.
Next, I doubt there will be someone paired with Yu, I just don't see it.
Fourth, some character will be OOC (like Atlanta) so deal with it please.
Finally, Yu's desire to compete in the war is because he feels guilty that he had taken Kariya's body and identity from him. He wants to help Sakura because he thinks Kariya would do the same.
If you haven't figured it out this takes place during the events of Fate/Zero and Yu takes Kariya's place and summoned Archer instead of Berserker.
Servants for the Story
