Yes I've done the unimaginable. While others have thought about it I have acted on it. A RWBY/Monster girl encyclopedia crossover. The idea came to me after discovering and reading MGE in a Harry Potter/MGE cross-over one-shot by whitetigerwolf titled: "The Monster's Husband" and later reading "Harry Potter: the Demon Prince" and "Harry Potter, Savor and Monster Lord," by DRAGONDAVE45.

Thank you both for making great stories and hope you make more in the future.

This is my second chance of making a story with the mystery presumed dead mother, Summer Rose. The first one has nearly 200 followers and gained nearly 100 favors before the second week was out. My hopes are for a similar following as things are about to get crazy with this story in the later chapters.

Note: this mostly going to be switching back and forth from either Summer or Ruby's point of view in the first couple of chapters. As I have trouble righting in a general point of view and apologies to all for any typo's I may have missed that you may find.

Another note: this is going to be three chapter story before it continues on to test the waters of how I'm going to make this work.

Enjoy and place your comments down below. I'd like to hear some feed back on your thoughts on this. Will continue if I have time.

Chapter 1: Rock bottom & forgotten memories

Faster. Faster. The girl in red ran desperately up the destroyed tower. Her mind was running through all that had happened to lead up to this. Beacon Academy was holding the Vytal Festival, the tournament it had brought schools from all the nations of Remnant to show the skills of their students. It was supposed to be fun and exciting but had been destroyed in the worst of ways imaginable.

Yang, her big sister, framed for an injustice she realized she didn't commit, followed soon by the death of her friend. Penny... Ruby steeled herself running faster to forget the memory, the sight of seeing her friend in pieces like that again made her want to cry. The thought of that brought the teen back to where she was now. Running up the tower to rescue another friend from certain death. Just hold on, I'm coming!

She ran with her semblance at full power, rose petals flying behind her caped hood just as she reached the top. The young teen landed at the top of the broken tower, her eyes transfixed at the figures before her. The large Grimm Dragon was watching from the other side of the tower. She saw a girl in a red dress, eyes a glowing gold holding a black bow and arrow before firing at her target. Her eyes widened in shock as the arrow pierced at the person she was supposed to protect. The red-headed huntress in training in golden armor was on her knees, a black arrow piercing her chest without the help of her Aura shielding her.

Pyrrha…? The hooded girl watched as the murderer of her friend stepped toward her, her hand touching her victims face when suddenly she flashed in a golden light. Soon Pyrrha's body began to turn to ash. Blown away by the wind with only her bronze circlet left on the ground. Not again… No… No… She was too late, she lost another friend, another friend died right in front of her eyes. It tore her apart. It angered her, seeing that murderer standing where her friend had died. She couldn't take it anymore, "PYRRHA!"

She screamed into the air, power flowing through eyes exploding with a flash of bright light that enveloped the tower. The dragon was soon enveloped in that very light as it seemed to scream in pain.

"What!?" The murderer was taken back by the sudden power and soon found even herself enveloped in the light. It shined bright all across Beacon but soon disappeared as fast as it came.

"What a lovely day." Said the monster.

At the edge of a vast forest roamed a single individual on an old deer trail. At first glance, she would appear to be human, but you couldn't be far from the truth if one would give a closer look.

Walking along the deer trail walked a she-demon, a succubus to be exact. Only she was oh so much more.

What walked stood the Current Demon Lord of the Demon Realm.

She stood tall, reaching nearly 6. 5 ft, with her black horns adding another 4 inches. Her skin was glistening pale skin reflects the light, bringing out a warm color to a bar of near light peach. Her eyes were red with silver pupils shinned in her black sclera eyes. Ears pointed out like those of an elf, and her sparkling smile showed abbreviated fangs. Large magnificent white bat wings folded on her back. The ends of her black horns horns, wing-talons, and tail adorned with blood-red gems, her snow-white hair tipped red at its ends cascaded down her back to her perfectly shaped childbearing hips like a wavy, white waterfall. Her hourglass figure and EE-cup breasts would make any man be swoon with her looks and make many women jealous of envy.

The Overlord had decided to take a walk in the nearby woods of her home. It had been such a long time since she had done so, years even. Between keeping the balance of power of ruling over demonkind, having fantastic sex daily with her magnificent husband, and being a mother to many children. She hadn't had much of any time to just take a walk and think about her life anymore. Even after living over a thousand years of doing so.

Most of her elder children were self-sustaining Lilim. Many of them live close by in either the castle or in the surrounding villages. A few have gone off and are currently traveling the world much like she did in her youth. Some even enjoyed it so much they prefer it over settling down and have traveled all over the globe, rarely coming home to visit. She was happy for them when they do as they told many adventures to their siblings and bring closer to each other as a family. A sight that always brought much pride to the Demon Lord.

Her thoughts vanished when she felt a powerful magick disturbance in the disturbance in the area nearby. The Demon Lord twisted her body towards the general direction of the power.

"What is this power?" She whispered. "It feels familiar...similar to that of holy magic of the gods but doesn't feel it. Nor does it feel like any Angel, Valkyrie, or other lesser deities either." The Overlord used her magic to get a better feel of it, but as quickly as it came, it vanished. From her spells, the Lord cast, she found a single young soul not far from her. "Well, now, this might prove interesting."

Heading to where the soul was, the Demon Lord couldn't help but wonder about who the owner of this power could be. There was also the point of why it felt familiar somehow but couldn't place it. The Demon Lord felt a little frustrated that she couldn't remember where she felt it from. She has a great memory of events and encounters, even after centuries of constant daily sex.

The direction led to an open clearing where a large oak tree stood solitary over. Feeling the soul, she felt earlier before a lot closer now. The life force that surrounded it felt weak, like a warrior resting peacefully after a considerable battle. But something else was confusing her. The soul felt human, but it was so similar to that of one of her daughters. That couldn't be possible? She hadn't sire any humans, nor does she remember any of her daughters having any human offspring. When a mother has a child, it is creating life in the purest form, no matter if its light or dark. When a new life is created from the mother, a piece of her soul detaches itself and becomes part of the new entity. Like a signature or a family crest. Reaching closer, the Demon Lord found out what had caught her query.

"Oh my. You held my interest, but now you have my attention." The Overlord looked closing at what she found. There lying was a fair-skin young woman.

Casting a few spells confirmed that the young women was indeed the source of the powerful wave of unique magic. The Overlord felt there was still magic in the so she waved her hand in a circular motion. The air grew warm as specs of light rose up and gathered into a little ball in her hand. She then conjured up a unique glass jar around it to keep the magic in place to study latter. Now looking back at the women.

She was out like a light and resting peacefully. Dark red shoulder-length hair laid out in the grass. The Demon Lord loved the black long-sleeved dress she had on with a high collar and red trim on the sleeves. They went well with the black stockings and strange black boots with red laces. To complete the look, a red hooded cloak fastened to her shoulders by cross-shaped pins. Lastly, she had a black belt with a red and black boxy construction under her waist that reminded her of the Automatons.

The Demon Lord noticed something shinning that looked like had fallen off the girl. Kneeling down, she picked up some kind of brooch that was pinned to the young women. Looking it over, she saw it was a...silver...rose.

*CLOCK!*

The Demon Lord head whipped back and clutched her head. A massive memory seal that she had just been broken when she caught sight of the large silver brooch of a rose on the black belt. It was a trigger for something she didn't think she will ever occur.

Her life as a human before she became a demon.

She had her memories sealed long ago, not long after she was forcefully monsterized. Women who've only just become monsters still have their human values, but with the monstrous body, that's hot for men. It was why she had them sealed in the first place. The intense feeling of hunger, the human mind can't hold out. Driven by desire, she would have ended up attacking any human men she came across. She had them sealed by a powerful witch in exchange for a favor, to which she paid off a century later.

Images and memories of being human were held back by the seal. With it now open flooded into Demon Lord's mind of her life before she got her demonic powers. Looking back at the young women, the answers to the questions that were cropping up in her head became as clear as the tears that fell from her eyes.

Summer Rose. That was her name. She had remembered her human name and of her firstborn daughter.

"Ruby?"

The Demon said in a fear-filled voice. Hoping beyond hope that this wasn't a dream. That Summer was seeing her firstborn again for the first time in a millennium. The young redhead stirred in her sleep but did not wake up. She knelt down to placed her hands on her long lost daughter, cupping her cheeks. She cast several medical scanning spells on her little flower.

She found that she had bruising over her body that was hidden under her clothing. Thou mostly what she found was that her daughter was exhausted, both physically and mentally. The Demon Lord was relieved to see she was unharmed. More more than that, she also cast a spell on her soul to confirm it was her daughter and came back positive.

"Impossible...You were born over a thousand years ago, and you look like your bearly an adult, how is this possible?" She asked. Her mind raced for questions, and the obvious was the answer. "Remnant is on a different realm so they must operate on different a time dilation. No wonder you're not a set of bones."

"Mother!"

Looking behind her, she saw many of her daughters in battle-ready armor landing near her. "Mother, are you alright?!" One of her Lilim asked her. She recognized her as one of her oldest daughters and captain of the castle guard.

"I'm fine, Elle. I'm fine." She reassured her daughter.

"Father sensed a great disturbance in the area of where you've gone and sent us to aid you if a battle had commenced. Is she the cause for all this?"

"She is, but she is not a threat. Return home and prepare a room. Have your father meet me when he is able. There is much to discuss..." The Demon Lord ordered her Lilim daughters.

Elle nodded and flew off, leaving two of her younger daughters behind. Turning back to her sleeping rose, she reached down and held the young women within her arms. The only way for her rose to get here is if she had activated the magic within her eyes. Something must have happened to her old home, and only her little Ruby knows what that is. She'd been neglecting her daughter long enough and has failed in her motherly duties. Someone had hurt her daughter, and as the former human Huntress Summer Rose, Current ruler of the Demon Realm, Lilith. She was ready to unleash hell.

Ruby is going to be in one hell of a wake up call.
