Warning before you continue:

The OC of this story will follow Rias Gremory because he doesn't have a choice. The beginning of this story is mostly (story-wise) the same as the original High School DxD because it is just the beginning of the story. The later chapters are in a way different than the original High School DxD. Also, the OC isn't a pervert. Now that's out of the way, enjoy reading.

My name is Akita Akio. My parents and students from my school call me "Aki".

I'm currently in highschool and in the second year.

I'm just a normal teenage boy, and I'm not that popular.

And no, I'm not a pervert who peeps at girls in the changing room.

I was in a room that has a hole on the wall; it is the storage room next to

the Kendo Club.

I didn't look in the hole. I was just looking at Matsuda and Motohama. Seriously, those perverts…

I look down at them in disgust, while they say perverted things.

I was fed up with them, so I left the scene.

After that, I found some students walking towards me. I told them what I saw, and continued walking.

However, something strange happened in front of me.

"Please go out with me."

A confession from a girl.

I felt confused.

For a guy like me who didn't have a girlfriend, and it was a first for me to receive a confession like that.

The name of my girlfriend is Amano Yuuma. She is a girl with silky black hair and a slender body.

I actually thought it was a prank. I even thought several times that it was the result of a penalty game and that her friends were looking at us from elsewhere.

That can't be helped. Until then, I believed that I was a guy born to be unpopular with girls.

But ever since that day, I became a guy with a girlfriend. After that, the world around me changed.

I started to feel sorry for the perverts, Matsuda and Motohama, who didn't have a girlfriend.

On our first date after we started dating—

I was ready to go on our date. I've brushed my teeth since yesterday night. I arrived at the date spot on time.

Before I arrived, I received a suspicious leaflet from a weird person handing out leaflets.

It was an occult leaflet with a weird magic-circle and a sentence - "Your dream will be granted!" - written.

I wanted to throw it away, but I decide to put it in my pocket.

When Yuuma arrived, I said this.

"I just got here too."

Then we walked while holding hands.

After that, we enjoyed our date by going to various shops ranging from clothing to furniture.

For lunch, we ate at a restaurant, while Yuuma chooses to eat chocolate parfait as a dessert; I choose to eat a donut.

I felt like she was faking her smile, and I also felt that something will go wrong later.

As I was thinking about all those sorts of things, it was already afternoon.

The date is nearly ending.

Will the date continue, or will we end it?

We are at the park that is away from the town. There is no sign of people, and no one is here besides us.

Yuuma already lets go of my hand and she is standing before the fountain.

"It sure was fun today."

Yuuma smiles while having the fountain behind her.

The sunset, which is behind her, gave a good atmosphere.

"Hey, Aki-kun."

"What is it, Yuuma?"

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

"What is your wish, Yuuma?"

Yuuma just continues to smile at me.

Then, she clearly says to me.

"Will you die for me?"

I knew there was something wrong with this girl. But, I decided to ask her to repeat it again.

"Sorry, can you repeat that again? I think there's something wrong with that question."

"Will you die for me?"

She clearly says it to me again while laughing.

Her words didn't make any sense.

FLAP

Black wings appear from her back.

She then starts to flap her wings. The black feathers float in the air and then drop down to my feet.

What is that?

Yuuma looks really similar to an angel. But, that can't be true, right?

Is it some kind of acting?

My beautiful girlfriend who is flapping her wings while the sunsets behind her. It looks like a scene from a fantasy story.

But there is no way I can believe something like this.

Her eyes change into cold scary eyes.

"It was fun. The short time I spent with you. It was like playing house with a little child."

Yuuma voice sounds very cold. Her tone is like an adult's. Her mouth is forming a cold smile.

BUZZ

A heavy sound vibrates in the air.

It's making a lot of buzzing noise and it appears in her hands.

A spear made out of light.

HYU

The sound of the wind with a nasty noise follows after it.

DON!

The moment I thought something grazed my stomach; the spear, which was in Yuuma's hand, pierces my stomach.

She threw that at me.

Then, the spear disappears, and the only thing left was a huge hole in my stomach. And blood which is flowing out from it. So much blood…

My head got dizzy, and my eyesight became blurry. I was already lying on the ground and by the time I realized it, my legs lost their balance.

Footsteps close in on me while I'm on the ground.

Then, Yuuma said in a small voice.

"Sorry. You were a threat to us, so we decided to get rid of you early. If you want to hold a grudge, then hate the God who put the Sacred Gear inside you."

Sacred Gear? That's the reason why she did all of this.

I can't even ask her a question and I'm in a state where I'm down on the ground. Her footsteps get further away from me.

At the same time, I started to lose my consciousness. The hole in my stomach must be fatal. I don't feel any pain.

But I realized that I was in a seriously bad condition because I could feel that I was about to lose consciousness.

Am I just going to die like this? Life is sure is strange.

Well... My life was short, but what can you do about it. You only live once (YOLO), right?

I can't even laugh in the situation I'm in.

…

My consciousness starts to fade away while I was having such thoughts.

…

It feels like many things inside me are disappearing.

…

Oh Yes, I wonder what's going to happen at school tomorrow?

Will my classmates be shocked? Will they cry for me?

I wonder what will happen to my mom, and dad…

It is hard to imagine what will happen…

Why I'm thinking of only these kinds of things when I'm about to die?

Huh? My hands can still move…

I touched my stomach and brought it in front of me.

My blood is crimson red. My whole hand is red. This is all my blood.

Then she came into my mind.

The one who I'm imagining is that one girl.

The beauty with the crimson hair, every time I saw her, my eyes were drawn to her crimson hair.

Huh? Why I'm thinking about her?

I started to feel like I am cheating on my girlfriend Yuuma because I am having these thoughts. Hold on, that Yuuma was the one who killed me…

Huh? I'm not dying…

Ha-ha, my thoughts don't stop even before I die...

My eyes got even blurrier...

Is this the end…?

Damn, I wanted to live a longer life...

…

"So you were the one who called me."

Suddenly, someone appears in front of me, and she talks to me.

I can't tell who it is since my eyes are blurry.

"Looks like you are dying. Oh my, looks like something interesting is happening to you. So it's you. This truly is interesting."

She's laughing as if she found something interesting.

What's so funny…?

"If you are dying, then I'll pick up your life. From now, you will live for me."

Before I lost consciousness, I saw a brilliant crimson hair in front of me.
