High School DxD Futa Harem x OP Shy Female Reader

Prologue

There was once a war between the 3 Factions. The Great War between the Angels, fallen Angels and Devils. In between the war of these 3 factions, there was one faction who didn't pick a side: the dragons. These powerful creatures only sought after there own goals. But then 2 dragons picked a fight, the 2 heavenly dragons albion and ddraig. Their fight brought chaos there were they appeared. The fight between the red and white one were stopped when the factions united and defeated the dragons. The war ended. Between this was a dragon who was feared even by god and the satans. A dragon beautiful, yet powerful. A dragon only sought by her greed to power. The dragons name was Fafnir. A dragon god even more powerful than great red and ophis. She would only need her 2 hands and then poof, both were gone. But this dragon we talk about is also lazy, lazy because of her absolute power. But one day she was challenge by a mere human. But this human had an ace in the sleeve. The sword gram, smithed for one purpose: to kill her. Ascalon may be a dragon killer but wasn't powerful enough to harm her. But this sword was an exception. It would not damage anything but her. The factions saw their chance and bestowed the mere human with blessings. To no avail. The prideful human thought, after the blessings, he was invincible. But Fafnir never underestimated her enemies, a rare thing for dragons, maybe that was what brought her power and saved her. She won. She defeated the human with magic that was never seen before or thought to be long lost. She knew too much. Then she did the unthinkable. She sealed herself with gram. She bound the sword to her soul so no one could use it but her. But that had its price. She died. But she couldn't die. She reincarnated, disguised as a sacred gear in a human which would be her reincarnation. The 3 faction accepted this, knowing they had a problem less to worry about for the time being. They ignored the signs and thought this monster would be forgotten and sealed to the end of time.

And here starts the story of our (Y/N). She awoke in a grass field. Not knowing what's happening she stood up. There she saw a huge dragon. Strangely she kept her calm. The dragon almost felt to her related.

Then it said: (Y/N). I'm Fafnir dragon god of power and greed. You and I are the same.

(Y/N) was shocked. What is this dragon saying? What is going on? We are not the same she thought.

Fafnir: You think we aren't? Then I will tell you this: you are my reincarnation. You are the new me and I will aid you on your journey. I want you to have fun. Live like a human in peace.

(Y/N): I have so many questions...

Fafnir: Then go on. We have enough time here in our dimension.

(Y/N): Our dimension?

Fafnir: Yes. I can control time and space. An easy task.

(Y/N): Who am I?

Fafnir: As I said, you are me and I am you. I sealed a powerful weapon but was weaknd in the progress. And i was through with the war and stuff. I wanted a new way of life, so I chose to reincarnate. Don't worry about you start. I got you a home and a school. And yes we will start at age 18. who needs the years before that anyway. Over in a blink of an eye, pff.

(Y/N): soo.. can you inform me on... maybe everything?!

Fafnir said the girl everything she needed to knew. She would go to kouh academy. Fafnir said, there would be funny stuff happening. Fafnir told the girl about angels, demons and the like. She knew know about the supernatural. Now a bit of common sense and boom we are good to go.

(Y/N): Okok. How do I start?

Fafnir: We will go now to our house. Put on the school uniform and start in your first day!
