"Curses! That damn Demonic Emperor will destroy everything, if he's not stopped."
These words were spoken by a long black haired woman, wearing white mystical robes. Surrounding her is a never ending void filled with stars. In front of her is a huge planet, bigger than earth.
"But no one in the seven worlds is capable of killing him. (Sigh!) I guess I have no choice. I'll just have to look elsewhere."
With that the woman disappears and goes deeper into the stars.

Earth (DxDverse)

The woman is now standing in front of Earth with a frown on her face.
"Hmm. Such a small world. I doubt I'll find anything here. But it won't hurt to look. World show me your history."
With words of power she commanded the world to obey. What she found surprised even her. As within this small world are beings unfamiliar to her known as god, unusual devils, and other creatures hiding from civilization. Another thing were the hidden realms surrounding the world. Some much bigger than the planet. Of course she could not find much because as soon as the other entities found her snooping around they quickly shut their doors, so to speak.
"Ohh! Their might be something here after all. World show me your greatest hero!"
With that she expected the results to come instantly. But after a few second nothing.
"Did I not do it correctly?"
OPPAI!
ZOOM ZOOM IYAAAAA!
"W-what?!"
I will be Harem King!
Soon images come into her head of a certain famous Oppai Dragon. At first she was revolted and disgusted by the perverted acts of this young boy. Peeping into girls changing room, ripping the clothes off his female opponents and his obsession. But soon that frown turns into a smile, as she watches deeper into who Hyoudou Issei is. By seeing the hardship and challenges that boy goes through.
Rias Gremory's virginity is mine!
Fighting for the freedom and honor of his love. Protecting an innocent girl that only wanted a friend. The bravery he showed even as the situation was hopeless. The rage he felt at the thought of his loved ones being in danger.
ASIAA!
And the madness he felt at almost losing something precious to him. Following the forbidden aria that should have never been said.
Soon the woman was no longer feeling disgust, instead she is now found with a face of full of expectations, joy and worry at the hero, with each victory and defeat, almost like a true fan of a show. She felt sadness at the grief the hero felt when he was betrayed by his first love. She cried when the boy died. And her face was full of joy at him coming back stronger than ever. She sees his opponents friendly rivalry, a true rival, the fallen, devils, dragons, gods, heroes, and monsters. With this she comes to a conclusion.
"I highly doubt I can convince the Infinite and Dream from leaving their domain. And while the White Dragon Emperor would fit right at home in my world, I believe it would cause more harm then good. So I guess I have no other option but to entrust my future to the Red Dragon Emperor." She says trying to save face and dignity by hiding her joy with a helpless attitude.

Night time, Hyoudou household, Issei's room.
A fifteen year old, Hyoudou Issei, was seen in an awkward sleeping position with a perverted expression on his sleeping face, probably dreaming about women. Suddenly the air shifted and out came the woman in white robes looking at the sleeping boy with joyful eyes.
"I doubt the Issei after becoming a devil will what to leave his women, family, and friends. So I guess this age should do. It weird such a weak, talentless boy, holds so much potential."
With that a light glow starts to shine around Issei as the woman holds his cheek affectionately. With that both then disappear.

Outside Martial World.

The woman is now seen in the outer space of a world with Issei still sleeping, floating beside her. After she sees her world her joy starts to fade. Soon a contemplated looked appears on her face.
Sigh! "I guess it just came to me. This world is cruel, a world filled with competition ready to leave anybody in the dust. For me to bring this innocent and honest boy to this world by ripping him from his home is beyond cruel. A part of me wants to take you back, but I came to far to change back. If we meet again and on your face shows nothing but hatred for me. I shall accept it by being killed by your hands. But a large part of me already knows that your face would only show acceptance and a will to help a woman in pain. Knowing that it only makes the feelings of guilt worse. Hah! To think that this Empress that once killed millions just for getting in my way would feel these emotions. My enemies would truly wonder if this is the same woman who murdered their family and disciples."
She soon turns to the boy trying to understand what caused this change.
"I guess I can only give you my love and adoration to you. I will do my best to help you and accomplish whatever dreams you have."
With a sad smile on her face she quickly captures the lips of Issei with that a glow shine on Issei's body.
"This should help you take your first step into cultivation and bring your connection to the Red Dragon closer. Also it is my show of my honesty to you. If I remember right the first kiss of a woman is special. "
Then a small mystical blue marble is then placed in Issei's hand.
"This is a treasure I found one day. Strangest thing is even I don't what it does. But I'm sure you'll find out. Until we meet again, Hyoudou Issei. I will keep watching until your strong enough to stand on your own two feet. Grow and never change."
