Disclaimer: I do not own Fate/Stay Night or High School DxD, or any of its character's, and make no money of this.

I find Fate/Stay Night-High School DxD crossovers rather entertaining so I decided to make my version of it (there might be some already used or cliché elements so plz don't hate me)

They say that if a person knows what his future holds he can either choose to accept and embrace it, while others will try to change it if they can't accept it.

But what can one do when he has a destiny that can't be changed no matter how much tries.

This is the story of a man who tried his best to bring happiness to the people he meet, sacrificing his own in the process. Some called him a hypocrite and a murderer, while others called him a Hero. He had only one dream, a world where everyone is happy, for that he tried to become a true hero. But in the end he never became the kind of hero he dreamed of, but he never gave up, driven by his dream and desire to one day reunite with his lost love.

But just because he failed to become his ideal hero in this world, that doesn't mean he can't become one in a different world.

Chapter 1:

Guardian of a new world

''Guess it's time.'' Were the single words a man uttered by a man standing on top a hill that was showing the landscape of the city know as Fuyuki, which lights were shining bright in the night.

The person was a man in his prime, late 20's or early 30. He is wearing a pair of black trousers, a black body armor that cover's most of muscular body except for his arms and a pair of metal plate shoes, which appear to be attached to his trousers. His skin was tanned as if he had travelled many dessert's, his spiky hair was pure white even though he was so young, and his eyes were same color as steel.

He was Emiya Shirou, ''The Wrought Iron Hero'' as some people have called him throughout the years.

He just sat on a nearby rock and gazed with sad eyes upon the city that was once his home town and reflected on what had happened 3 days ago.

3 days ago

Shirou POV

''GRAHHHHHHHHH!'' a black monster with blood red eyes screamed as it prepared a stream of dark magic to attack me with it.

''RHO AIAS.'' I shouted as the seven petal shield of the hero of the Trojan War ''Aias the Great'' appeared and blocked the dark attack. It was quite powerful being able to destroy 1 of Aias's petals, after all each petal was the equivalent of a fortress.

As the attack dispersed, I charger straight to the monster while projecting my favorite sword's, Kansho and Bakuya, but they would only stay in their current form for only a few seconds.

''TRACE OVEREDGE!'' I shouted as the swords began to grow and take the appearance of a pair of black and white angel wings.

I ran in front of the monster which was still recovering its prana from using the powerful attack. With swift speed I swung Kansho over its chest while immediately stabbing the monster with Bakuya into its neck.

''HHrrrrr...'' was all the demon was able to say. Black blood was dripping out of the demon's wounds as the light in its eyes was fading away.

I made my swords disappear and began walking towards a massive stone door. As I was walking I took a look at my body and frowned when I saw how it was covered with its black blood. All I could do was sigh.

''Man... I sure can't stand monsters.'' I said while looking at the monsters remains and remembered that this was not the first monster I had slain ... actually I lost track on how many I had slain.

I arrived in front of the door that the monster was guarding and with a gentle push I opened it. It was a tomb of some kind and in the middle was a monument on which a pure white jewel was placed, the size of it was as big as my palm.

''If Tohsaka saw it she would probably be drooling now.'' I thought with a small nostalgic smile on my face.

I slowly extended my hand and picked the stone. Everything changed when I touched it...

Images...or exactly memories... memories of my life started invading my mind... but were these my memories?

I saw different sets of memories, some were identical at first until they reach a certain points in my life ... The start of the 5th Holy Grail war.

I witnessed old and new memories, some which brought a smile while others brought horror and disgust. I fell on my knees while patting and trembling. Grabbing my head to stop the surge of pain that was invading it.

''Just what's going on?!'' I shouted as I couldn't understand what was going on.

I saw what one would call a corrupt Saber getting killed by my very own hands.

I saw a modern dressed Gilgamesh kill Illya and rip her heart out... or at what was supposed to be a heart.

I saw Saber disappears in front of me.

I saw Illya sacrificing herself to save me from my own death.

I saw a battle with Kotomine Kirei that I never had.

I saw a battle with Archer that I never had.

I saw the image of Sakura getting raped by Shinji.

I saw myself battle Berserker and defeating him.

I kept seeing different memories that were never my own, yet I knew they were mine. However my mind simply couldn't keep up and went blank and I passed out.

I began slowly opening my eyes, but closed them back moments later, my head felt like I went drinking all night.

I began to pull myself up, only to notice I wasn't wearing any shirt and that I was in a different place. I'm in a simple western room, it had a one person bed on which I was lying down and a wooden desk. But at that desk there was an old man dressed into a fancy suit with an ornamented mantle.

He was Kischur Zelretch Schweinorg one of five living Magicians capable of True Magic beyond modern science or Magecraft.

''Ara Ara Shirou-kun finally awake?'' he said with a laid back attitude while he was admiring the very jewel I touched earlier.

''Zelretch-san what are you doing here?'' I asked as I stood up and put a nearby black shirt on me.

''Well I thought you were taking rather long to finish the job I gave you so I came to check how you were, you should be grateful to me, you might have caught cold on that freezing floor.'' he said while smirking with that laid back personality which I just can't understand.

I then remembered what happened when I touched that jewel and I started to sweat.

''J-Just what is that jewel, the moment I touched it, it did something to my mind, I started remembering things I never done or more like I saw different lives I could have had. ''

''Hhhmmmm so it affected you huh? Well I guess I need to explain it to you.'' he sighted as he seemed to be lazy to do it.

It was then that he dropped the carefree expression and took a serious face.

''You see Shirou-kun this is a raw version of my Jewel Sword or more precise this is the main material that my jewel sword is made of. '' He explained while he took his sword out of his cape.

I was in literal shock, that jewel was the same as his sword, one of the few weapons I could never trace, more like one of the few weapons I wasn't even able to analyse.

''Don't be so shocked, you of all people should know that a good sword is made out of a rare material or two.'' he grinned like a kid.

''You see that jewel has power over dimensions, to be honest I didn't expect this to happen, maybe the fact that you made a contract with Alaya had an effect with it.''

''Do you have any idea what exactly happened?'' I asked as confused as earlier not understand what he meant.

''Well...you see Shirou-kun, what you saw were the lives of parallel versions of you, when you touched the jewel it made a link between you and other versions of yourself, but that's not all.''

''What do you mean?'' I thought what he's saying sounds kind of crazy, but considering what I saw in my life I'm ready to believe anything.

''You see while you were passed out I examined you and reached a conclusion, the memories you saw merged with you own.''

''Merged?'' I ask confused.

''Yes the memories, experiences and emotions of the other Emiya Shirou's became your own.''

''I think I understand, but these memories confuse me, I feel like not myself anymore.'' I said as I was looking in a mirror in the room, even though I look the same something just feels very different.

''Then answer this, who do you love?'' he asked with a mischievous smile.

''Huh it's simple, it's Sabe-'' I stopped myself out of embarrassment... even though at my age it shouldn't affect me anymore.

''See your still the same, while you gained their memories, experiences and emotion's they didn't change you, otherwise you might have said you loved Rin Totsaka or Sakura Mato which some of your counter parts did.''

''But let's see if the event caused what I believed it did.'' he replied as the childish smirk disappeared.

''Shirou try projecting something.''

I don't understand why but simply nodded and started projecting.

''Trace on.''

I decided to trace Kansho and Bakuya but I was speechless.

''Ho ho so I was right it did happen.'' he said while holding his chin with his hand.

''What going on?! The quality of my projections increased and the level of stress on my magic circuits was reduced drastically!'' I said with awe.

''You already know the answer just remember.''

It was then that I remembered the fight with Archer as I learned the secrets about projection, the battle with Gilgamesh and my path to become a hero of justice.

''You understand know, what you might think of an inconvenience is actually gift of the other Emiya Shirou's that took a different path than you.''

I actually found it interesting but it all was gone when I began digging deeper into those memories... a tragedy was about to take place... my bright face suddenly turned dark as I learned the truth.

''How long was I out?'' I ask emotionless.

''2 days.'' he said with a serious tone.

''So the day after tomorrow I will be executed huh?'' I ask emotionless.

''So you saw that one's memories huh.''

''It already started. Before you gave me this mission I was confronted by a calamity which had the potential of killing one hundred people before me, I decided to "make a contract" with the World to become a hero capable of producing miracles and become a Heroic Spirit after my death. I believed I could save both the lives of the dying people before me and save even more people as a hero after my death. Although I desperately fought to end a war, tomorrow I will be branded as the mastermind behind that war and subsequently executed because of the betrayal of my own allies.''

''And then you will become the counter guardian Emiya and exist to eliminate the possible threats of the world.''

''How did he know? I can't seem to grasp his level of information gathering.''

''Or at least that is what is supposed to happen, but I thought what if we can cheat fate.'' he said with a devilish smirk on his face. I was beginning to get scarred.

''Well Shirou that's why I sent you for that jewel, to give you a chance for a new life.'' he said while he was showing the jewel I secured.

''Huh?'' I blinked in a funny manner to this.

''Here's my offer: tomorrow night before you will be captured and executed for a crime you never committed I will send you to a world that is cut off by our world's grasps.'' he said while taking a dramatic pose.

''So you would just let me go to God knows where?'' I ask with a stupefied face.

''As ridiculous as it sounds it's not a joke, while I travelled to different worlds I came across a world that would be called a paradise for a mage overflowing with prana and without the existence of the WORLD or the existence of the counter force.'' he said while I was in pure shock.

''The counter force is a linked existence throughout worlds, even if you escape to a different world if that world has a counter force it will strike you the moment you enter... but this world is your salvation.''

''... I just can't believe what his saying, he is telling me that the only way for to not die and become a soulless killing machine was to in exile into an uncharted world.''

''Why? Why would you risk so much just to help me, a third rate magus like me, there must be more to it isn't it? '' I couldn't help not believing him, even if he knew about my destiny and had a means to stop it why would he do it, we weren't exactly friends, the only reason he would do it would be if he had something to gain from it.

''Dang you sure are paranoid one but your right, I'm not doing it just to help you, even thought that world doesn't have a counter force somehow I can't maintain myself there for too long because otherwise I will be transporter to a random world and believe me it's a real pain in the butt to find my way back here. '' He released an annoyed sigh as he seemed too remembered past experiences.

''So you want to send me there as a spy?'' I ask in serious tone considering it could be dangerous.

''Mmmmm not quite, more like an observer, just live an everyday life and observe how their world works, I will craft you an item similar to my sword but with a surveillance function so I can study that world.''

''It's not a bad deal you know, I get to have my curiosity satisfied and you will get to live a normal life.''

''I'm not sure what to say, you're telling me to defy my destiny and go in to an unknown world.'' although the thought of living a possible quiet and peaceful life seems very tempting it would be meaningless without her.

''Well aren't you good at doing business, then how about I add something extra if you will help me. If you do this until I say its over, I'll make sure that you will be able to meet her.'' the old mad said with a big smirk on his face .

My eyes literally exploded, is he tricking me? No actually it could be possible for him to do, if there isn't any known method to do it in our world but he could have come across one in his traveling towards different worlds.

''Well you still have time until tonight so think carefully.'' he said as he left my room and give me time to think.

Present day

I kept thinking what to do while staring at the moonless night until I finally found my answer.

I got up and arched my back and declare my answer to the world.

''SABER THERE ISN'T A DAY THAT GOES BY WITHOUT ME THINKING OF YOU, I KNOW WHAT I'M ABOUT TO DO MIGHT BE A MISTAKE BUT I'LL TAKE ON ANY CHALLENGE THAT AWAITS ME. IF THAT'S WHAT I NEED TO DO TO SEE YOU AGAIN SO PLEASE WAIT A LITTLE LONGER.'' I shouted like there was no tomorrow which was about right I either get executed or get sent to a different world, either way this was my last day this were my real feelings the life without Saber was empty and I've been searching for a way reunite with her but all was in vain, but this could be my only chance to find her.

''What a touching speech.'' Zelretch began whipping he tears. '' I should have filmed it, it would have been big a hit.''

''H-How long have you been there?'' I ask him with a blushed face

''For a while actually, I've wondered how long you will keep staring at the sky but I guess the waiting was worth it.'' he replied with his idiotic grin.

''Well jokes aside I take it you will accept my offer.''

''Yes ...even though I am betraying many people with my selfish desire I'm prepared.''

I am ready this is the path I must follow not just for me but also for my counter parts.

''Haven't seen that determination in your eyes in a very long time.'' the old man smirked but it was somehow happy one as he just saw an old friend after a very long time.

He then pulled a necklace out his pocket, I could tell immediately that it was made of the jewel he made me he gave it to me I felt nostalgic while I saw it. The jewel was shaped as a sword, her sword.

''Meet the Jewel Necklace of Zelretch, with this you will be able to travel to that world and keep in touch with me, also it has a built in surveillance system so anything you learn I learn. '' He explained as he was pointing to the necklace.

''So is there anything I need to know about this new world?''

''To be honest I don't know much myself, but technological their about a few years behind us, but when it comes to magic they seem to have a more developed system than ours since their world isn't as restricted as ours, I believe you will be able to use your magecraft more efficiently there.''

''But don't go around using your powers, while their magic is more developed they do seem to keep it as secret as our world does.''

''I think it goes without saying you can't say anyone you're from a different world, I mean you realize if you do that they will either think you're crazy or lock you up to interrogate you''

''Oh damn and wanted to go on and show off.'' I said in a sarcastic voice

''I have prepared what you need here: clothes, money, documents and other things you might need to use. '' He explained as he handed me a black metal suit case.

''Then prepare I'll open the portal shortly.'' he walked of and started to open a gate with his sword.

''Guess this is goodbye everyone, I'm sorry I couldn't say goodbye the proper way.'' I slowly looked one last time to my old hometown.

''Bye Totsaka, Sakura, Caren, Fuji-nee, Luvia, Issei, Mitsuzuri and... Saber.''

''Don't worry I didn't forget about you.'' I said as I slowly picked some nearby flowers and made a small bouquet.

I went to the edge of the cliff and summoned my bow and normal arrow. I tied the bouquet on the arrow then shot I looked in the distance. I see it did hit the mark.

At a grave that wrote ''Illyasviel Emiya''.

''Bye Illya, onii-chan will be gone for a while.'' I slowly started walking towards the now open portal.

''Oh right before I go take this.'' he said as he placed a weird piece of paper with odd markings on my chest, but the paper disappeared instantly as if it entered my body.

''What did you just do?'' I asked in shock.

''Let's just say I updated your arsenal.'' he said with a smirk

When he said that I concentrated and I saw them: swords, armors, bows, staffs, spears, axes and the list went on. He basically gave me a mental encyclopaedia of our world's legendary weapons, while I did receive a big choice of weapons from the Emiya that fought against Gilgamesh, this list has detailed information that I-no I mean that Emiya didn't have time to record during the fight.

''You never know when you might need those, so I thought I'd make you sure you don't die out on me. Make me proud kid.'' he said with a big smirk on his face.

Somehow I feel touched.

''I'm of.'' I said with small smile on my face as I jumped into the portal

Few seconds later

''AAAGGHHHHHHHHHHHH!'' I screamed I was literally being twisted around in the vortex of magic, it feels like I'm inside a freaking washing machine. How could that old man do this all the time?

A few minutes have passed, I felt like every cell in my body was screaming from the stress it was going through.

At last I saw a light, then I saw the sky...wait the sky... SHIT IM FALLING!

Guess even thought my luck is E-rank I was lucky today, it was just 20 meters above ground, and I landed on grass.

''Ouchhhhh... man he should have told me that it was going to a rough ride.'' I was fuming as I was getting up from the ground.

[''So Shirou are you there?''] I hear Zelretch voice but I couldn't realize where it was coming from then I noticed the necklace was in the ground so I reached for it.

''Guess I am, damn I'm surprised I'm still alive.'' I sighted as was dusting my hair, funny thing my hair felt rather different.

[''What the...but how...why...could it be a time line difference, but that never happened before.''] Zelretch was trying to say something but was panicking, that was a first.

''What are you rambling about?'' I asked as I got up from the ground.

[''Shirou... Trace a mirror.''] He said with a serious voice.

A mirror? Why would I trace a mirror? Actually can I even trace a mirror? I can trace kitchen utensils when I cook, but a mirror? Oh well might as well try.

''Trace on.''

A simple hand mirror appeared in my hand, I just looked in awe for a moment after which I realized what was in the mirror.

''WHATTTTTTTTTTTTTTTTTTTTTTTTTT?!'' I shouted as was examining myself. I looked the same as I looked during the holy grail war, my hair was rusty red again , my skin was white again, my eyes turned back to their golden color...but the only difference is that my height didn't too change.

''I'm a teen again...'' I just sighted as looked at the sky

[''I don't know why but it somehow happened...perhaps it has to do with your contact with the jewel before forging it the necklace or perhaps this world has a different time flow.''] He just seemed to go on rumbling as he couldn't find an answer, I just let him finish his debate and began checking my surrounding I was in a park, a rather nice one it reminding me of the one back in Fuyuki.

[''Shirou before you go anywhere how about putting some clothes on?''] Zelretch said with a chuckle.

As I looked at myself I noticed that my clothes were in a complete mess, more like they were almost gone.

''R-right.'' I said as was opened the black suitcase and changes my clothes behind a tree.

''Guess I'll need some new clothes, these are too big for me now '' I said as the clothes I was wearing now were hanging on me.

Even thought my height didn't change my muscles did, they are still bigger and better than they were during the grail war but their still small for my clothes.

[''Now Shir... Huh wha... Damn can't...''] the old man was trying to say something but I couldn't understand.

''Zelretch I can't understand what you're saying.'' I shouted to the necklace.

[Shirou...communication...can't...signal...good luck Shi...''] and he was just cut off.

''Guess I'm all alone now huh.'' I said as I sighted and started walking

And so a month has passed

''Thank you so much Emiya-kun for helping us again.'' a girl with glasses told me with a smile.

''Nah it's not a big deal, I like to give a helping hand whenever I can Shinra-san.'' a replied a small smile on my face.

After I lost communication with Zelretch I wondered around the city in search for a place to stay, I initially thought I'd have to get a part-time job to have money for rent but when I checked the suit case my eyes popped out... That old man did tell me he put some money in my luggage but ...does some mean to him 1 FRICKING MILLION DOLLARS?!

I MEAN REALLY 1 MILLION DOLLARS!?

I know I need money but 1 million really? Well after I thought a little, it was a little logic Zelretch did send here to act as an observer of this world and he probably known that I would have refused the money if he told me the amount, and I'd rather get a part-time job and that would have meant I'd spend a lot of time of the day working.

So since I can't send him the money back I thought I might as well use it. What does surprise me is that this world has the same money as my own.

I bought a place to stay, a traditional Japanese home, it has 2 bedrooms, a bath, a living room, but most important it has a BIG kitchen.

Don't get shocked about the 2 bedroom thing, I'm living alone but I'm using one bedroom as a training room, for physical training and projection training, since Zelretch gave me a lot of new items I can project.

Even thought my appearance changed I am still tall, my face and features are back to how they were when I was 17 years. Because of this I had to do something I didn't think I would ever do.

Go back to school... Yeah I know, kinda obvious right? Well it can't be helped, it would be weird if a kid would go wondering all around the city all day long. Don't want unnecessary attention.

As weird as it sounds a school could be a good place to study this world, like studying how normal people act here, what is common sense I modified the documents Zelretch gave me and enrolled at a high school in this town call Kuoh Academy.

I heard it went co-ed in the recent years, this could explain why there are some many girls here... not that it matters to me.

From what I realized the past month of observation, our worlds are pretty similar or at least when it comes to education and common sense, also it seems that this world history is the same as mine or at least the public one.

I tried to keep a low profile so I didn't join any clubs or join any groups, but it seems as my body returned to how it was when I was 17 so had some old habits.

More precise my helping habits.

''But really Emiya-kun you help people too much, ever since you transferred here a month ago you've been helping each club with their electric equipment, but also been doing any small task anyone has asked you and you don't want anything in return.'' she said with a calm and collected tone.

This person here is Tsubaki Shinra the Vice-President of Kuoh Academy's Student Council.

''Well that's the kind of person I am.'' I replied with a small chuckle.

''But really people starting calling you The Scarlet Saint of Kuoh Academy.'' she said with a small smile and I mean very small smile which was pretty rare for her.

I released a small sight at this... I mean come on.

''I've been called many things during my life but a Scarlet Saint really?'' I replied with a tired expression.

''Must be your hair, you're the only male student here with that hair color, remember the first day you transferred here, the President stopped you in the corridor and demanded you wash your hair dye.'' she said with a calm face.

''How could I forget, I took me a long time to convince her that this was my natural hair color, although with the risk of sounding mean it was a bit amusing how she got embarrassed after the situation was cleared, she kinda reminded me of an old friend.'' I said while I remembered Totsaka, even though she always tried to keep a perfect student image it was pretty amusing when she got embarrassed.

I guess this is what that Lancer meant by 'it's amusing to tease a girl'.

We arrived shortly at the student council room, as we entered we were greeted by the members.

''Oh morning Emiya-san.'' I was greeted a blushing Momo Hanakai, wonder if she's sick?

''Hello Emiya-senpai.'' I was greeted by Ruruko Nimura.

''Yo Emiya.'' I was greeted by Saji Genshirō the only male member of the council it seems.

''Oh Emiya-san helping us again?'' the president Sona asked with a curios face.

''No I'm just passing by with a box in my hand'' I replied with a sarcastic voice.

''Well anyways thank you, did you get adjusted to our school?''

''Pretty good, the courses are ok, I go along with of my classmates but some of the guys seem to hate me for a reason.'' at this reply the girls started chuckling at it as if they knew the reason.

''Well it's good to know you're doing fine. I hope you don't mind but we are going to have a council meeting in a few minutes, would you mind if you leave us?''

''No problem, I was going to leave anyway.''

I simply left the room and closed the door behind me.

''Did you figure something Tsubaki?'' Sona asked with a serious tone

''I can't tell, he seems to have a unique magical signature like nothing I felt before. I'm not sure if it's sacred gear or if he belongs to a different species or if his a human magician.''

''But his magical signature ...how should I put it...feels sharp...like a blade.''

''A blade?'' all students asked in unison

''It's like his very existence was forged like a blade...it's like you would get cut down if you get in his path.''

''Do you think he might be a threat?'' Sona asked confused of her colleague's statement.

''That I don't know, I never meet someone so complex, while he does seem a kind and gentle person it feels like if make a mistake I will be cut down. ''

''Guess we will have to wait and see what he's planning.''

''They figured me already it seems.'' I thought while I was leaning against a wall

After I received the memories of my counter parts I learned many new techniques, one of them is Advance Self Reinforcement, a superior version of Self difference. The difference in quality is something similar between iron and steel.

A handy one technique but one mistake and I can end up crippling the reinforced area. By reinforcing my ears, I can hear what the student council was talking about me even through thick walls.

''Well it can't be helped that they suspect me considering that their concept of magic is different than mine, guess I need to suppress my mana presence more than I do.''

I know already that in this school there are a number of mana presences most of them coming from the student council and a club called the occult research club. What makes keep my projections on standby every time I meet any member of those two groups is that their energies smell somehow demonic, but it doesn't feel evil but rather it's like their filled with desires...that and the fact that they don't look anything like the demons in my world.

I can't say I trust the members of the student council but they don't seem to be a threat... or at least not yet so I decided to take it easy and not risk any incident that might end involving the students. I guess you can say that I'm enjoying a quiet high school life for the moment.

I went outside and just laid on the grass and enjoy the sun and started thinking what should I make tonight for dinner.

My shear of thought was cut soon after though.

''GET THEM, DON'T LET THEM ESCAPE!'' I heard many girls shout as 3 guys were running towards me.

They were Kuoh Academy's Famous Perverted Trio: Issei, Matsuda and Motohama.

They were going to arrive next to me judging by their speed in the next 5 second's and by the look of the girl's faces, they would probably beat them up pretty bad so I decided to interfere. They were about to pass by me, I grabbed Issei by the collar and lifted him up, it was a rather funny image as he was still running in the air.

''Ahghhh!'' was all Issei could say since his oxygen was cut off from his head.

''W-what the heck man let me go! Guys help me out here!'' Issei shouted at his friends who didn't stop running.

''Issei you're on your own!'' the other 2 members of the pervert trio declared as they ran away.

''TRAITORS!'' Issei said as he was crying in a funny manner.

''KYAHHHH Emiya-senpai caught one of them.'' the girls said in union.

''He's so cool. '' A girl said.

''And tall.'' the second girl said.

''And handsome.'' the third girl said.

''Peaking?'' I asked even thought I already knew the answer.

''YESSSSSSS!'' they all said with unison with rage in their eyes.

''Well how about I teach him a lesson and you girls go after the other two, not to gossip but they were calling you stupid a few seconds ago for not going after them.'' I said with a smirk on my face.

''THEIR DEAD!'' the girls shouted in unison as they went after the other 2 perverts

''Guess I'm starting to behave like Archer more than I thought.''

I simply put Issei down and set next to him.

''Can't believe that you never learn Issei. '' I asked him while releasing small sigh.

I don't know about the other two that were with him but Issei isn't a bad kid, but he's just a first class pervert and the irony of fate we live in the same neighbourhood and if that wasn't enough were even classmates.

''Oh shut up. A popular guy like you can't understand how I feel, just how do you do it anyway did you sign a contract with a devil or something?'' He asked with tears in his face.

''Would you have preferred to let the girls castrate you?'' I ask with a smirk on my face.

''...fine you win.'' he said with a pissed off face.

''Issei you must realize that if you continue like these girls will keep running away from you. ''

''I know ...BUT I CAN'T HELP IT, I LOVE BOOBS!'' he shouted with all his might. I could only sigh at him.

''I'm not saying you should change your taste but try to control yourself until you get a girlfriend.''

''...'' he was just staring to that old building.

''Hello Issei you ok?'' I asked as he simply stared.

''Did he froze or something?'' I Wondered

''Beautiful.'' he said with a blush on his face

''Huh?'' I said while looking where Issei was starring, at the window of the old school building there was a beautiful girl with long red hair.

''I knew who she is... She is the president of the occult research club.'' I thought as I remembered seeing her sometimes in the school halls, she's kinda like the top idol of our school. I must say she is quite gorgeous. But her smell is intoxication, she definitely has a very dangerous power around her, like it pure destruction.

The school bell rang

''Guess I'll see you later Issei.'' I said while getting up.

''Huh...oh yeah bye.''

''Guess I'll go shopping for dinner later. ''

A few hours later I was in the shopping district and finished my groceries shopping.

The sun was slowly fading and the sky was getting painted red, it was what some people would call a romantic setting. I was walking and a girl was approaching me, she had long black hair, purple eyes and wore a school uniform, judging by her looks she was about my age, or at least my current age. She was slowly approaching me and just passed by me but...not until she sent me a chill on the back of my spine.

Her smell...The smell I got from her was somehow similar to the ones at school but unlike the ones I felt from the students from my school hers felt tainted...like something that was once white got tainted black. However, the thing that really startled me was the feeling she was emitting ...blood thirst...like a wild animal that just spotted a new pray and it's waiting for the perfect moment to strike.

As I turned my head back she was gone...even her presence was gone.

''I need to be more careful next time I meet her.''

NEXT DAY

It started as a normal day...or at least that was I thought.

Issei came to me all happy and told me that he got a girlfriend...at first I didn't believe him and thought he was joking...that was until he presented her to me.

...What shocked me wasn't the fact that he got a girlfriend but rather the fact that the girl that is in front in me right now is that black haired girl I saw yesterday.

''SOOOOO Shirou this is Yuma-chan, MY GIRLFRIEND.'' he said while boosting himself like he was superior or something.

''Nice to meet you Emiya-san.'' she said with a gentle smile yet I can't help but be cautions as she wanted to shake hands.

''The pleasure is all mine.'' I said while faking a smile.

The moment I shook her hand my suspicions were confirmed... Blood thirst ...and is way bigger than yesterday. I'm starting to suspect that Issei's life may be in danger... I have to do something.

''Well Shirou if you'll excuse us we got a date to on today.''

''Bye Bye Emiya-san'' she said with a sweet voice.

''Have fun then.'' it was all I could say with a fake smile...I'm not the same reckless kid I was before, if I had interfered right now Issei could be in danger so I need to strike when I confirm that she's a threat.

I follow them from the distance with help of my reinforced eye-sight but what I saw shocked me.

Issei...Issei...Issei took her on a classic date...

They went shopping, eating, he bought her a gift ... The heck it reminded me of my date with Saber. I would have never thought that a pervert like Issei would be so pure.

''Was I overeating and confusing blood thirst for passion...during their date she never once tried to harm Issei, was I really wrong about her? '' But my suspicions were confirmed when they stopped at an artesian fountain.

I felt something cover the surrounding area ...it felt like a kind of bounded field and the sky began to darken.

I knew something was wrong...and it was clear when Yuma changed, her clothes changed into something similar to what a prostitute would wear, her gentle smile was now replaced by a sadistic one, but what struck me were the 2 black wings that erupted out her back but my gaze then change to the spear of light she formed in her hand.

''SHIT, SHIT, SHIT!'' was all that was going through my mind as I bursted towards them reinforcing my legs to increase my speed and also using prana burst.

''Would you mind dying for me?'' were her last words before she threw her spear of light towards Issei.

So this was chapter 1 hope you liked it

This chapter was a Shirou POV but the next ones are gonna be from authors perspective.

I tried to explain how Shirou got in DxD world with a believable story.

About the memories part: my OTP is shirouxsaber but I like the Shirou from UBW more so I thought to merge them but I thought why not merge all Shirou's together, it will play some parts in the future chapters.
