High School Blade Works:

A High School DxD and Fate Stay Night crossover

Disclaimer: I don't own Fate Stay Night, Kinoko Nasu does. The same goes for High School DxD. For the first thing this disclaimer is meaningless. To those concerned, I am just a faceless person sitting in front of a computer. So why am I typing this disclaimer in the first place?

…Tradition, I guess.

Chapter 1: Twist in Fate

-x-x-x-

My name is Hyoudou Issei. Second year high school student attending Kuoh High. I cannot say I am proud of it, but I am extremely perverted.

Peeking at the Kendo Club from the lockers, peeking at the Athletics Club from a bush, peeking at the Swimming Club while…

My nose starts bleeding at the last memory.

Anyway, I am famous for being extremely lecherous.

Due to my reputation, the chance of my getting at a girlfriend is slightly above 0%.

So, it came as a surprise to when a cute girl named Amano Yuuma confessed to me.

"W-will you go out with me?" Her shy words still ring in my years. Actually, I thought it was a prank and she confessed to me on some sort of dare.

But ever since that day, I became a guy with a girlfriend. The world around me changed. I was in some sort of peace. I wanted to say 'it's my win' to every guy I walked past.

Anyway, it's my first date with Yuuma.

I arrived at the meeting spot three hours before Yuuma-chan did. As I waited counting meganekkos who walked past me, I received a suspicious leaflet from a weird person handing out leaflets. It had an occult feel, with a magic circle and a sentence- "Your dream will be granted."- written.

I wanted to throw it away, but since I couldn't see a rubbish bin, I stuffed it in my pocket.

When Yuuma-chan arrived, I said, "Don't worry, I also just got here." I always wanted to say that!

Yuuma and I walked while holding hands. Walking while holding hands with my girlfriend, what a dream come true!

We enjoyed our date by going to a clothing store and having a look at decorations for our rooms.

For lunch, we ate at a family restaurant like ordinary high school students. As I watched Yuuma eat her chocolate parfait, my stomach felt full just by looking at her.

So this what teenagers feel while going on dates. I felt like I was really alive for the first time. In my mind, I thanked my parents for giving birth to me.

As I was thinking about these things, afternoon had passed by. The climax of our date approached.

We were at a park that was away from the town. There was no sign of people, and no one was there beside us. My erotic imagination hyped up.

Yuuma-chan, having let go of my hand, is standing before the fountain. "It sure was fun today." As she smiled, the sunset behind her gave a good atmosphere.

"Hey, Ise-kun."

"What is it, Yuuma-chan?"

"There is something I want to do to celebrate our first date. Can you listen to my wish?"

This-this must be it!

"W-what is the w-wish you want?" The tone of my voice is deep and I stuttered. Damn! I finally blew it!

But Yuuma-chan just smiles at me, reassuring me.

I tense in anticipation. My first kiss-

"Will you please die for me?"

-x-x-x-

-Wait, what?!

Yuuma says these words with a cruel smile. Her outfit for our date is replaced with a bondage suit. Black wings pop up behind her back. In a flash of light, a glowing spear of light appears in her hands.

She flies in the air with her wings which most definitely cannot sustain her body. Taking aim with her spear in a javelin throwing stance, her eyes lock on my chest-

This is a dream. This cannot be anything other than a dream. Meanwhile, I am convincing myself to deny reality.

Just when the spear is thrown…

Dodge to the right.

A voice appears in my head, directing me.

Surprisingly, my body obeys. The spear aimed at my stomach only cuts my shirt.

Who are you? I question the voice in my head.

Who am I… currently there is no time to answer any questions. Do you want to live?

Of course!

And what are you willing to give up to achieve that?

Anything!

…To match her weapon, you need a weapon of your own. Fight her with this.

The image of two black and white twin steel blades appears in my mind.

"Trace… on." My body heats up. In a flash of light, the swords in my mind appear in my hands.

There's just a little problem…

I don't know how to wield them.

As I question the voice inside my head, I am replied with a disappointing answer.

Damn. Telling you to replicate that magic in a moment's notice was a hopeless task wasn't it? I am sorry, I couldn't save you… The voice is filled with despair. But I can't accept that! I don't want to die!

"Hahahaha! This is the Sacred Gear I was forced to track! Pathetic! What are you going to do with those swords? Throw them at me?"

Desperately, I do just that. The black blade in my right hand… I throw it at Yuuma.

Yuuma doesn't even try to dodge. Nevertheless, I completely miss.

"Pathetic. Well, it's getting late. I'll kill you quickly and go home." Saying that, another glowing spear appears in Yuuma's arms.

As she aims the spear, I give in to my despair. I have already accepted my death. My greatest desire… what was it, a harem? That shit doesn't even happen in anime, how could a pathetic person like me get a harem in reality? Just as Yuuma said, I am pathetic.

Do not despair. Even if it's your final moment… face it standing up. Like a man. The voice in my head reappears. It cannot save me. All it can do is offer me advice, which cannot save me.

…No, I have something which can save me, don't I?

The spear falls. I move before it can hit me. Even though I tried my best, there is still a hole in my shoulder.

But the adrenaline coursing through me nullifies the pain I should be feeling.

"Trace on." The black and white blades reappear. Once again, I throw them. The black blade misses completely. The white blade reaches near her, but is parried by Yuuma.

Once again, Yuuma summons her spear.

Once again, I dodge.

Throw. Throw. Dodge.

Throw. Throw. Dodge.

Throw. Throw. Dodge…

Five minutes later, the ground is littered with spears of light and black and white swords. My body is burning from the heat created with the use of the magic.

My body is completely exhausted, running purely on adrenaline. On the other hand, Yuuma looks like she is mildly annoyed.

"Well, Kalawarner will get pissed if I come back late. Sorry, this ends right here." Summoning her spear in her hand, she swoops down to stab me.

I back away as fast as I can. But at this moment, my body betrays me. My feet won't move. Swords won't appear.

My desperate desire to live overrides my body's surrender. Just as Yuuma stabs at my chest, I fall down in a crouch. As surprise fills her face, I claw at her feet with my hands…

…I don't know exactly what I did, but I managed to make her fall.

I need a sword, but swords won't appear. So, I pick up a blade buried into the ground.

Before Yuuma gets up, I clumsily slash her leg. As she screams, I realize that a slash to the leg won't stop her.

I get up from my crouch and stand up. Coldly, mechanically, I stab her in the heart.

A single gasp. That's all that comes from Yuuma before she dies.

I am left staring at the body. It doesn't magically disappear after her death.

Silky black hair. Slender body.

The violet eyes, still open after death. The surprised expression. The black wings, broken. Bloody chest. Bloody feet.

This image, I'll never forget it.

Unbidden, memories flow into my mind.

-The attractive girl in the school uniform. She came out of nowhere and confessed to me. I immediately accepted.

-Boasting to Matsuda and Motoyama about a girlfriend.

-Picking out clothes for my date.

-Getting to the meeting spot 3 hours early.

Yuuma's expression as we met, Yuuma's expression as we went on our date, Yuuma's expression as she announced my death...

The adrenaline leaves my body. I am going to faint. The wound on my shoulder won't kill me, but when I wake up, I'll be surrounded by weapons and a dead body…

Before fainting, I make a wish.

I wish all this never happened.

-x-x-x-

It's evening.

Yesterday, I returned from a training trip with Okita Souji-sensei. Even though he badly bruised me, I learnt many strong sword techniques.

Today, despite all, the exhaustion, I valiantly attended high school. Of course, I didn't absorb anything, but that will be remedied by a study session with the Occult Club.

As I was just lazing around in exhaustion in my bedroom, my pocket heated up.

…Damn, looks like my devil services are needed by a client.

I make my way to the magic circle carefully hidden by shelves.

Standing between the magic circle, I pour my demonic energy into the circle.

As I wait for the teleportation spell to activate, I cannot help but wonder who is calling for me.

I sure as hell hope it isn't some rich middle aged woman…

…

…It looks like a battle occurred. Swords and light spears are buried in the ground.

A Fallen Angel is lying dead on the ground.

Also, a human has also collapsed on the ground. Wait… those spiky hair look familiar…

"I-Issei!" I check him. Except for the hole on his shoulder and a large number of cuts and bruises, he looks alright.

As I check his pulse, he wakes up. "K-Kiba! Can you help me up?"

As I help him up, he glances at the dead body. Knowing what would happen, I back away as he empties his stomach on the ground.

"Are you okay?" Concerned, I ask him.

"Do I look okay?"

"Sorry. What happened?" I patiently hear as he tells me his sorry tale. From this, I conclude that he must have been attacked by a rogue Fallen feeling threatened about his Sacred Gear.

But what Sacred Gear would be strong enough for them to feel threatened?

As I am thinking, Issei gives one last cough. I brace myself for his questioning.

"So, how did you get here so quickly?" Oh, that's easy.

"I teleported here."

"Yeah, figured- wait, what!?"

"The explanation's kinda long, so I'll explain it to you tomorrow. Meanwhile, I'll help you cover this up. Can you take care of the swords?"

I draw up a magic circle around the Fallen's body as Issei makes the swords disappear. From this, it appears that Issei's Sacred Gear is a Sword-type Sacred Gear, just like mine.

For now, I'll concentrate on covering this up. I'll ask Issei about the details tomorrow.

-x-x-x-

The Fallen Angel Kalawarner is looking at the two boys, floating in the air with black wings. She was going to take care of the kid, but that plan got foiled after the Gremory Servant's appearance.

…Well, I'll just report to Kokabiel and hope he doesn't get too pissed off.

Five minutes later, she is safely in the old Church which is also the Fallen Angel hideout, magically talking with Kokabiel.

"…So, not only did Raynare get herself killed, you even failed to take down that boy?" The displeasure in his voice is evident. To appease him, Kalawarner quickly says, "W-wait! I found out about the kid's Sacred Gear! It created black and white short swords!"

"Black and white short swords! Could it be…" The voice on the other side appears to be thinking about something.

Hesitantly, Kalawarner says, "If you want me to, I could kill that boy later…"

"…No. Don't attack that boy. Actually, leave him alone for now. If it's who I am thinking about, he'll get stronger quickly. After that happens, maybe I'll fight him myself…" As Kalawarner fights to hide her confusion from her tone, the Fallen Angel Kokabiel reminisces about the greatest battle he ever fought in, and a certain red knight.

A/N- So, in this fic, Archer takes Ddraig's place. What changes will it make…

Actually, I don't know myself.

The name of Issei's new Sacred Gear, Archer's backstory, Issei's joining the Devils, Issei's Element and Origin, the possessor of the Boosted Gear Longinus… all these are to be decided.

For the first thing, I added an F S/N Style opening. How was it? Do you think Issei will still be a harem seeker after killing his first girlfriend? What about the Occult Club?

Note: Page segments fixed!

Please PM/ review your questions and opinions. I have yet to decide whether or not to continue this fic.
