Author's Note: Welcome to my first fanfiction ever. I hope this little imagination outlet of mine can provide some form of mediocre entertainment to whoever bothers reading this. Feel free to review or not, and I'm always open to suggestions. If you didn't bother reading through the whole summary then read this. THIS CONTAINS YURI. In fact. Almost all the romance in this will be yuri as the OC (generously provided by the true ending of One Way Heroics Plus. Great game, should totally check it out) is indeed female and will be replacing Issei. So if hate the idea of girls kissing girls (and the main character not being a Mary Sue) then you might not enjoy this. Even if this OC has the power to control reality, none of that will done in the battles. This will mostly follow the canon story with a few changes here and there to accommodate Saya's personality. I'm always open to suggestions about who to add to the harem though, and I'll try fulfill those wishes.

Tl;DR: First story, review if you want, yuri, FemOC replaces Issei, yuri, no Mary Sue, harem suggestions

This is a fanmade parody. Highschool DxD is originally written by Ichiei Ishibumi. I take absolutely no credit for the original canon of the story.

"Hey~! Wake up! If you don't wake up I'll... stab you~!"

"Hey~! Wake up! If you don't wake up I'll... stab you~!"

"Hey~! Wake up! If you don't-" *click*

My hand retracted from the novelty alarm clock's head before I rubbed the sleep out of my eyes and sat up. I sighed and slid out of my bed to begin with my morning routines.

It's already been sixteen years since I've been born into this world. It may sound like a strange way to say how old I am, but in actuality, this isn't the first life I've lived. In truth, I am the recently appointed (if you can call roughly 200 years recent) Dimensional Ruler, a being that is able to travel through space and time and to bend reality to my will. This will have been my fourth life, my fourth journey, the fourth world I've been to since I got my powers. And to be honest, I absolutely hate it. It definitely is nice to be able to experience all the different worlds I go to. My adventurer spirit can attest to that.

I violently shook my head to bring myself out of my thoughts as I finished brushing my hair. Now wasn't the time to be thinking of these kinds of things. For now, I'm just another normal high school student with an ancient dragon sleeping inside of her.

Standing up, I examined myself for any stray mishaps on my school uniform once more. It was the standard Kuoh girl's uniform that consisted of a white long-sleeved, button-down shirt with vertical linings, a black shoulder cape, a matching button-down corset, a magenta skirt with white accents, and a black ribbon tie to finish it off. Satisfied with my look, I nod and head downstairs for breakfast.

The morning commute to school was normal enough. Nothing out of the ordinary today either. It was a good sign. I wouldn't have to be dragged into this world's problems just yet. Peace was something I've learned to enjoy during my travels with the amount of chaos that followed me. Just then, a sudden collection shrieks from my right side broke me from my reverie.

"Kya! It's Saya-sama!"

"Saya-sama~!"

"Marry me, Saya-sama!"

I turned to see who it was only for me to find out that it was a gaggle of female followers I had garnered the attention of. Not to brag or anything, but I am quite the celebrity being one of the three great onee-sama's of the school. The other two being a red-haired third year by the name of Rias Gremory who is the president of the Occult Research club (spooky), and another third year by the name of Souna Shitori who is the president of the student council. They both excelled in anything and everything they did and they both had looks that any man (or woman) would fall for. Unlike them, though, who both had bombshell bodies, mine was slender and didn't have much going on at the chest region. Not to mention I was only a second year. I only managed to get the title because of my helpful nature.

Smiling and waving to all of my admirers, I mentally groan at all the attention I was receiving as I make my way to my classroom.

"For the last time. I am only interested in other girls, and even if I was into guys, I would never consider going out with you two dolts." I sigh exasperatedly when I repeated my sexual preferences for the umpteenth time to the Perverted Duo of the school; Motohama and Matsuda.

"And yet, you still hang out with the two of us like it's no big deal Miss Third." Motohama adjusted his glasses while saying that.

"Well, I'm just trying to live up to my expectations as the third Onee-sama by trying to stop you two from perving on girls all the time."

Matsuda's eye twitched. "Of course we would! This school is a paradise for us true men! We came to this school in hopes of having casual sex with hot chicks and then never see them again! They should all be jumping at the chance to sex us up but you and that damn pretty boy prince keeps stealing all our chances from us!"

All I could do was sigh again and tune Matsuda out as he began rambling on again. This was how I spent a lot of my time after school ever since this school turned co-ed. I have no idea why I befriended these two, in fact, it didn't even start like that in the beginning. All I wanted to do was try to reform these two from extreme perverts to at least slightly more approachable perverts. As it stands now, though, even I couldn't do anything to fix their behavior.

Suddenly, I feel a chill run down my back causing me to look around for the source of it before my dark blue eyes finally landed upon a pair of green-blue ones staring at me from a window of the old school building. I didn't have a chance to see who it was before they turned around and disappeared into the shadows. I did catch a glimpse of a crimson hair though.

I stand up from the area my 'friends' and I were sitting at and brush the grass off of my skirt before starting on my way home. "I'm going home for now, you two. Don't stay out too late, and don't bother looking for those mags of yours. I've already burned them."

Just as I was exiting the school gate I hear a shy voice try to grab my attention.

"Um... Excuse me... Are you Hyoudou Saya by any chance?"

I turn to see that a girl around my height had approached me. Her appearance wasn't much to look at, but she had an almost classic girl next door look to her with her straight black hair and kind looking eyes. She had on a school uniform that I didn't quite recognize although it did have an emblem with the letter 'P' on it.

"Yes, I am, can I help you?" I reply with a small smile.

She fidgeted a bit while glancing around nervously before finally meeting my eyes again. "Well... Are you seeing anyone right now?"

"Hm... No. Not at the moment. Why?"

Once those words left my mouth her face immediately lit up with a smile. "Oh. Well in that case would you like to be my girlfriend?"

I played around with the idea in my mind for a few seconds. Maybe if I found myself a lover I could tone down the constant fangirling I get from my peers especially because this girl was from another school.

"I don't see why not. But I think it'd be a start if you introduced yourself first. I think it would get pretty old if I just called you beautiful all the time."

I smirked as the girl's face lit up in a blush before she managed to stammer out. "O-oh, right I'm s-sorry. My name is Amano Yuuma. Um... H-how does this Sunday sound for a date."

"Wonderful. How about we meet up at the plaza?"

The girl, Amano Yuuma, nodded happily. "Yes! That sounds great! Here, I'll give you my number so we can stay in contact."

After we've exchanged cell phone numbers, she bounded away while waving back at me as I waved back.

The next few days of school went by normally as nothing out of ordinary happened. I did announce my relationship status to Motohama and Matsuda in hopes that they would start some rumors to get all of the lesbians in school to stop trying to get my affection. Of course, I made sure not to mention the girl's name as I didn't want to cause her unneeded trouble. All I said was that I just started going out with a girl from another school.

And so, the day of the date finally arrived and I was waiting at the promised location. While I was waiting for Yuuma to arrive a girl dressed up in a bat themed costume gave me some sort of strange flyer with a magic symbol on the back. I just dismissed it as I folded it and pocketed it. I made sure to arrive half an hour early so I had time to go over the day's plan in my head. It wasn't much, really, standard run-off-the-mill first date stuff. Go to the movies, have lunch at a cafe, go shopping, and wrap it all up with a stroll through the park. I kind of felt bad for the girl. She was definitely attractive, but I was only using her as a means to an ends. I didn't ever want to have real friends or fall in love after my second journey. The girl would probably be heart broken if she knew how I really felt.

"Saya-saaan!"

I smile and wave to Yuuma as she ran towards me.

"Sorry if I'm late."

"Don't worry about it. We both got here early. Well? Shall we go?"

I took a hold of her hand before leading her away to our first destination of the day.

The movie we watched was some old horror movie about this crazy possessive girl that murders her boyfriends if she even finds a picture of their ex or something. I wasn't really paying attention to it much to be honest. Yuuma seemed to enjoy it a whole lot for some reason at least.

Next, we went to a cafe that was nearby the theater. To food wasn't much but hearing Yuuma talk about her life and her friends was surprisingly heart warming. For desert, we shared a special couple's parfait.

The stores we went to after lunch were mostly clothing stores and we took turns showing off each other's choices. I... hate to admit it but I got caught up in the moment and had a little too much fun. In the end, we each bought our favorite choices and got matching key-chains for our phones. Her smile was too genuine when I gave her the key-chain and I found myself start to fall for her. Even though I know I shouldn't.

Now at the climax at of the date, we were silently walking hand-in-hand in the park enjoying the glow of the setting sun. My face had a smile plastered on it, but my mind was in turmoil. I had started to care for this girl, Amano Yuuma. I had started wanting to be with her more. Her smile, her innocence, I wanted to see more of it. I couldn't help it. I was always too influential. Always too impulsive. Not to mention, she reminded me of her.

When we reached the fountain at the center of the park, she suddenly let go of my hand and walked ahead of me before turning around.

"Hey... Can I ask you a question?"

I just smiled and urged her to continue. Ignoring the growing unease I was feeling.

"In commemoration of our first date... I'd like for you to do something..." She paused before leaning into my ear and whispering. "Can you die for me?"

I gasp and my eyes shoot open in shock, "What? I'm sorry. I don't think I quite heard you."

Yuuma smiled sadly and stepped back. "I had a lot of fun today to be honest, and I didn't want to do this to begin with." A bright light began enveloping her and when it dispersed, it revealed Yuuma with two black feathered wings sticking out of her back dressed in... something that you should only see a girl wear in a strip club. I would have sweat dropped at the sudden change from innocent schoolgirl to stripper dominatrix if my brain wasn't still trying to process what she had said before.

Before I could react I felt a sharp pain erupt from my stomach and I look down only to see that a spear made out of what looked like light had pierced through me.

"Damn, I let my guard down... If only Ddraig was awake," I thought as I dropped to my knees. It all made sense now. The feeling of foreboding when I first met her. The sad looks she would sometimes shoot me when she thought I wasn't looking. Her name as well. Yuuma, meaning 'evening daze'.

"I'm sorry you had to die like this. If you're going to blame anyone. Then blame God for putting that Sacred Gear inside of you." With those last words, Yuuma took off and flew into the distance.

"This is what happens when I let my emotions get the better of me. I shouldn't have been hit by that. I can't die now. Not yet. Not while... I still have work... to do..." I could feel my consciousness fading away as I lay in a pool of my own blood. "Ah... This feeling again... So familiar..." Red. Red was all I could see now. Such a beautiful color. Red. "Just like her hair." Red. "Who was she again..?" Red. "Rias..." Red. "Gremory..." Red.

Just as the last vestiges of my life was slipping away, I caught a bright light shine at the edge of my vision, followed by a muffled voice.

Black.
