nobody's POV

After that near death experience Rin was now in a heavy debt to the mysterious new master Shirou Emiya the kid from school she was laughing to death of the idea Shirou could ever challenge her authority really in the Fifth HGW but he had Saber so she had to really be on her guard or else risk Saber killing both and then Shirou somehow winning in the end Rin thought to herself of such a possibility it was so utterly ludicrous yet plausible after all I mean Saber is the strongest servant after all right???

After Rin had retreated back home with Archer EMIYA meanwhile...

Shirou: dang that was really something now what am I going to do how am I going to explain all of this to Fuji Nee and Sakura that I randomly summoned a girl Sakura is gonna freak out and probably ditch me for good because she might think I am dating this girl oh crap what do I do oh boy ding dong.

And so a bell was rung to which Shirou wss really confused as no one usually comes at this hour and those who do are exceptions not the rule but even so Shirou decided to go up to the door and thus opened it to which he was shocked as it was Rin Tohsaka who was standing there

"Hello Shirou how are you doing I am here for a very special reason but I don't think you will get it until I tell you when I come inside so will you let me in Shirou?" (Rin)

"of course Rin I will let you inside i mean you are someone I vaguely recognize beforehand and also someone from school I can't decline a classmate now can I!" (Shirou)

and thus Shirou and Rin then proceeded to go inside and were walking around Emiya's house as they were walking towards the part where Shirou had busted the window pane to Escape Cu Chulainn Rin then spoke up,

"its freezing Shirou why is that and what do you mean that this glass pane is shattered what was going on here to explain this away Mr.?" (Rin)

"Well its not my fault alright so stop trying to accuse me of stuff i would never do I was defending myself alright he killed me the first time and I decided i didn't want to die by his hand yet again so then i devised a plan to defend myself against his attack that he had" (Shirou)

"Wait you fought him all on your own and without help or any mage training? until you were able to fortunately summon Saber who fought the guy off is that correct?" (Rin)

"Hardly actually I couldn't even fight back against him at all tbh he kept cornering me and if I stopped once I would have met the same fate yet again" (Shirou)

"huh and your not even trying to brag about the fact you lasted so long against a decently strong servant you are exactly how you look a simple and super innocent and honest guy who would never cheat anyone or anything for personal gain or deceit" (Rin)

thus Rin then proceeded to treat the broken window that Shirou had made using a german incantation to repair broken or destroyed matter

"Wow Tohsaka I didn't know you were a mage I always thought you were a school model nothing more but this is something else entirely I never knew that." (Shirou)

"yes I am a mage Emiya and I assume you are too given how you summoned Saber too and how you somewhat fought back against Lancer" (Rin)

"Me not me I can't do something as big and sophisticated and big as what you just had finished thus now" (Shirou)

"What do you mean you can't do this your messing with me now Emiya this is about as basic as you can get without being a total dunce" (Rin)

"Well I don't know a thing about basics or fundamentals about magecraft yes I am being completely serious about this mind Tohsaka before you think I am messing with your mind or whatever nonsense you want to come up with ok I trust you believe me?" (Shirou)

"Ughh how is it that some dunce like was able to Summon Saber I don't get it at all like if you had no magic how could you pull Saber in to this time without a magical conduit in the summoning circle or whatever ughhh you fool well that's fine however it happened we need to rebalance the scales so far" (Rin)

"Alright now you have absolutely no idea what you have been dragged in to now do you" (Rin)

"No I don't have any idea of what I am caught up in tbh" (Shirou)

"To be absolutely blunt Shirou you have been chosen by the Grail to be the seventh master have you ever noticed some sting mana anywhere Shirou?" (Rin)

"Sting mana I don't get it Rin?" (Shirou)

"She means Command Seals Shirou Saber then spoke up"

Oh you mean this Shirou stated with a honest look on his face

"Yes that's exactly what I meant Command Seals are unbreakable magic spells that a master can use to force his servant to obey even if it means overriding there free will and using them to perform any task that said master requires as long as you have one of those you can keep your servant under control you will most likely be killed if you actually have the audacity to use them all up too quickly so use yours wisely plus you already used one on Saber to get her to break off her attack on me and the red man." (Rin)

"Wait I will be killed if I use them up too quickly why will I die Tohsaka?" (Shirou)

"The holy grail war is a battle to the death between seven mages and seven masters it is based on masters defeating other masters and the one who beats the other six would gain access to the holy grail a all powerful wish granting device that can materialize any wish the master would have or would want to come true" (Rin)

"Wait why are you telling me all of this information.?" (Shirou)

Because, you have been dragged in to a certain ritual that is the HGW where as I stated its a battle to the death between seven mages and seven servants!"

"Wait hold on do you honestly expect me to believe all of that crap already?" (Shirou)

"I am just laying out all the facts as they are simple as that besides its not like your totally ignorant because deep down inside you know already about the battle to the death part after all you have nearly been killed by a servant twice the same one might I add convinced yet I am another mage that was chosen to be a master by the grail think of your servant as a powerful familiar granted to you by the grail to help you survive the HGW." (Rin)

"She doesn't look like a familiar to me to be blunt with you!" (Shirou)

"Of she doesn't servants are technically familiars but really there beings who come from a higher plain of reality far different to the human world Heroic Spirits from the past" (Rin)

"A hero from the past Saber! is that true?" (Shirou)

"Yes Heroic Spirits are Heroes from Legend that are pulled from the past and present and summoned to fight alongside the master who summoned them in our time it's the master will that gives them form and substance it's the duty of the master to summon them and once materialized the grail helps them keep there physical form. Servants are always with you in Spirit form but should the need arise they can be materialized at will by the masters orders and fight alongside you if you wish" (Rin)

"So the guy in red can change between spirit form and physical form at will?" (Shirou)

"yes and that's Archer he is keeping an eye out incase things get rough or an intruder comes our way so do you understand so far?" (Rin)

"Yes I sort of get it so far" (Shirou)

"For a more detailed Explanation you should talk to the man overseeing the grail war at the church which is in another city there is also another thing to keep in mind once you have been chosen as a master you have no choice but to fight and servants are powerful familiars so make sure you use yours well." (Rin)

"And as for you Saber based on the information Emiya told me i gathered that you are in an incomplete state?" (Rin)

"Yes the fact is Shirou is not a trained master so even replenishing mana will be very difficult!" (Saber)

"That's pretty shocking Rin stated with a surprised look on her face"

"Hey I am confused what are you guys even talking about here I don't get it in the first place unless you explain it to me?" (Shirou)

"A servant maintains it's physical existence through getting replenished by there master but she can't get an adequate amount of mana from you that's what I am saying because you are a novice and you don't know how to focus your talent it will be a problem before too long btw" (Rin)

"Oh would you like a cup of tea Emiya.?"

"No thanks I am good here Tohsaka"

"I gotta say Saber I didn't expect you to be so open with me about your current condition" (Rin)

"There was no point lying about my condition you had already figured out something was indeed wrong with my condition so I thus opened up to make Shirou realise the light of his situation in these current circumstances" (Saber)

"Wow she is the king alright after all sips tea" (Rin)

"smashes the glass oh if only I and not this bum peasant was Sabers master I would have killed everyone else already that idiot idiot he is so weak what a waste indeed abd I will kill Kirei for good measure too I will eliminate this loose end soon I am only keeping him around for my own pity and amusement just like Sakura when the time comes I will kill both and laugh and piss at there graves" (Rin)

"Huh are you trying to say I am not worthy of Saber" (Shirou)

"Of course I am you hack and Piece of garbage that's all you will be so take my advice and know I will slay you soon when we meet as enemies" (Rin)

"How dare you insult me you little piece of s*it you c*nt who the f*ck are you speaking to wh*re I am talking to you huh next time don't f*ck*ng get in my way you bastard I didn't bargin to listen to another one of your lies Shirou yelled unintentionally as if something had possessed him with his eyes glowing Mahogany Bright Yellow instead of brown with his face looking with anger and hate." (Shirou)

"Rin was shook and scared for the first time in her life as she then looked on in disbelief Shirou I never thought you were that kind of person You monster your evil ok!" (Rin)

"Tohsaka I didn't mean to say that that was a accident I had no idea frankly what happened myself please you have to believe me please I beg of you I had no idea what happened just now!" (Shirou)

"ok then I believe you Shirou so shall we go then?" (Rin)

"What! now where going its like 2 AM why now PS where are we even going in the first place?" (Shirou)

"To see the man who knows everything there is to know about the grail war you do want to know the reason behind I mean don't you?" (Rin)

"Of course I do but its kind of getting late If I am being honest" (Shirou)

"Its what you won't go fine thats your judgment call to make what about you Saber?" (Rin)

"Leave her out ok I don't want to go and neither does she alright plus don't attempt to strong arm her she is not your servant alright plus if she really is a hero from the past then she has no idea about our modern times?" (Shirou)

"Shirou that's not exactly true Servants adapt to whatever time period they are summoned in as such I am quite familiar with the modern world besides this is not the first time that I have been summoned to this era of history.!" (Saber)

"No way,! what are the odds of that, you had fought in the last war too Saber honestly I am shocked at this revelation Saber?" (Rin)

"Anyways you can go Tohsaka before you overstay your welcome too much freak!" (Shirou)

Moreover, after Rin left Shirou decided to go to bed and skip school tomorrow after all there was no harm in skipping school for one day right however...

as we will soon see unusual stuff is about to indeed go down soon enough.

Shirou woke up one day and also got out of bed it was 11 AM and it was going usually smooth but Shirou felt off as if something had flipped or as if a switch had been activated but Shirou was really confused at this point?.

Shirou got up and said Dang what happened wait why is my voice is deeper and I feel taller? wait let me go check

As such Shirou then went to the washroom and checked the mirror he was much taller he grew about 7 inches over night from 5'6"/168 CM to about 6'1" or 185 CM he was really confused by such a state not only that but adding to that his eyes were yellow with a mahogany outline at the end of the iris and his hair has darken from orangish red to a much darker red he then stated "wow I must of gone to the otherside because I have no Idea how I grew so Large and why my hair and eyes are so different but oh well let me go visit Saber"

Shirou then visited his friend/heroic spirit Saber as he then said well well Saber why don't I get you some new clothing because that cuck Rin never bothered to give you anything what a moron (Shirou)

Saber looked abruptly at Shirou and then said "Master your much taller than before also your hair is darker and your eyes glow much more sinister then before plus you are using more crude language why is that?"

"Tbh IDK myself and I don't know how I ended up this way so I need a bit of time to adjust and stabilize but I was thinking now that that c*nt gave us the priests location why don't we check it out huh I mean it sounds like good buisness and an chance for me to get registered in the HGW properly don't you think?" (Shirou)

"hmm I agree it will solidify the bond between us and also might clear up some confusion that you may be experiencing right now!." (Saber)

"Alright off we go ladies Shirou then got ready by shopping for new clothes and he got Saber new clothing yk the iconic white dress shirt and black leggings and dark blue skirt alright its time for us to leave Saber" (Shirou)

Shirou then checked the TV soon and thus he found a news report of a man killing the Japenese mafia what the wait wait don't tell me Shirou turned the TV off in a fit of rage as he said DON'T TELL ME KIRITSUGU F*CK*NG EMIYA is alive again I better hope that damn TV report was a lie if it's not I will make that c*nt suffer for not being nice to me.

Shirou then exited the house in a fit of rage with Saber and then the two started walking as Shirou was walking Saber opened up by asking a question

Saber: So Shirou why are you so worked up don't get offended by that question but I was wondering it's a complete 180 from your persona yesterday Shirou IK we just met like for a day but still I find it odd that my master had such a sudden change

Shirou: so you really wanna know Huh Saber you want to know why I am the way I am huh alright then I will tell you ok so once upon a time it all begin with the day of the Last War when the disgusting mud spilled over I was a survivor of that war and I was lost my parents had been killed by that c*nt Kiritsugu Emiya prior and what makes it worse is that he was the one with that smug face who was not nice to me after he coerced me to be adopted by him he abused and beat me down everyday that deadbeat he was always too busy trying to force me to become the bulls*it hero of justice which is a lie a elaborate lie that c*cksucker was the worst not only that but he also beat me up regularly and also kept trying to get rid of me even when I was a kid and then he said I was a monster the absolutely filthiest part was I looked up to that moron inspite of all that had happened was that I kept believing in all of his lies every single one of them Saber no joke or exaggeration what so ever alright that moron was worse then a Gangbanger or a motorcyclist not only that he once abandoned me in a shopping mall a few days after I was taken in and after I was lost I burned it all down and killed everything in a fit of rage also that F*ck*r abused and r*pd me with a freaggin hockey stick you know how that feels huh Saber do you do you that *ss wipe will suffer and his lackeys alright you served someone in the Fourth HGW who was your master Who F*ck*ng who who who who

Saber: Shirou calm down alright listen I served Kiritsugu Emiya himself I never exactly got along with Kiritsugu but damn I didn't expect him to be this much of a sick bastard I am sorry for not understanding you earlier Shirou I apologize continue on anyways were almost there.

Shirou: So As I was saying what comes out in the dark comes back up in the light so after that idiot kept his nonsense on me he died the best thing he did oh you know Miss Fujimarua yeah she turned a blind eye to Kiritsugus parental abuses and overreach I finally Feel F*ck*ng free once more I hope that F*ck*r isn't alive if he is I am going to make him suffer

Saber: that's intense Shirou no wonder your so crazy and a psychopath man I am serious about that so we are here.

And so Shirou and Saber arrived at the church and were now going to enter the front gates

Shirou: lets hope this Priest isn't a f*ck*n judas or traitor is all I am saying oh yeah

they entered the building and were greeted by the fake priest aka Kirei Kotomine aka Mr Yorokobe Shonen as he closed his bible and said oh a odd guest I assume you are the Master of Saber Young Master well then my name is Kirei Kotomine and I am the overseer of the Fifth HGW my job is to provide refuge for fallen masters whom lost there servants and to oversee and meditate the war what is your name! or shall I call you seventh master

Shirou: my name is SHIROU that's all I forgot my last name alright fake priest

Kirei: Ahh I see you must be I take it Sabers master then

Shirou: yes I am why do you bother asking me right now.

Kirei: Because so I can properly Register you as a master and your servant as well besides I assume you know about the HGW or do I assume you don't know?

Shirou: I don't know a f*ck*ng thing about this masters and servants bull*it alright I need you priest man to explain it all from the start alright cause I am not technically a proper mage not that I am complaining I am not some Loveless virgin

Kirei: very well then young Shirou the ritual that you now find yourself in is known as the Holy Grail War

Shirou: a war about a bunch of c*cksnots fighting to the death am I right?

Kirei: elaborated further yes its about that and the whole ritual is a test to see which mage is worthy of holding the grail the one who wins gets the grail

Shirou: woah woah woah bulls*it detector is going off I hope you aren't making this up you fat f*ck

Kirei: but I am not the Grail that appears in the city is the real deal it's a all powerful wish device that can grant any desire and also fulfill any wish the master may have besides for more proof of its power look at the miracle of the servants that inhabit the grail a device capable of that can most certainly grant any wish that you may have and that is the HGW

Shirou: woah woah woah mr fat idiot I have a final question what happens if a servant dies before the master?

Kirei: interesting question to answer that that master will seek refuge in my church and then team up with a servant that's lost master and rejoin the war also there status as master will not vanish after the demise of there servants you need that plus the emptying of the command seals to finally push them out of the war for good

Shirou: thank you fat mother f*ck*ng f*ck for that thank you now I am off to do my business but I have one question or rather request may I train with you you see I suck at magecraft and I need a little bit of a boost so how does that sound huh now give me some of that g damn X now huh

Kirei: hmmm that sounds reasonable on the condition you keep it secret from everyone else got it

Shirou: yes sir I will not tell all the idiot morons about this I promise that much

after that Shirou then went back home and sat down thinking of his strategy to enter the war and planning ahead...

(Wow guys that was something anyways hope you enjoyed it and comment down below what your thoughts are and any suggestions to improve or add to next chapters also some are confused why I may want Kiritsugu alive somehow IMO for this Emo Shirou it will add a inner conflict and a another obstacle for him to conquer and for him to crush his ghosts from the past that's all)
