Please forgive my spelling and grammar, my ipad doesn't have spellcheck. This story was pretty heavily inspired by behind the wall, so go check out SarottiFlotti's story. Also, I don't own Miraculous Ladybug.
Fifteen years ago, a man was hit by a car. He was unconscious and rushed to the hospital. There, they drew blood from him. As soon as the doctor punctured the mans arm with the needle, the mans whole form rippled. His flesh seemed to melt away from his body, leaving behind a creature, if it could even be considered a creature. It had no definite shape, consisting of an almost solid shadow, with the only definitive feature being a vague human head. After the doctors watched the entire transformation in muted terror, the beast woke up. Where before there was intelligence and recognition, now its eyes were like staring into a black hole. They seemed to suck all of the light out of the room, leaving behind only the beasts muted purple eyes. The purple eyes had an almost hypnotizing effect, they had a sort of otherworldly beauty that seemed to suck you in. If the doctors weren't horrified before, the beast made sure of it. It opened its mouth and showed that it did have a few physical objects, teeth. They were sharper than razor blades, and appeared to be coated in a purple substance. The monster did not only open its mouth to show off its teeth, it also let out a cry that seemed to reverberate in the doctors ears, causing them to fall to the ground with open mouths as if screaming, but while their mouths looked like screaming, no sound came out. The monster seemed to grin, or as close as it could get to a smile, with its shadowed face.
Marinette heard a noise in the hallway outside of her room. She stood silently from her bed, unsheathed her knife with the quiet rasp of metal on leather, and moved to the left of her doorway. The doorway slowly opened without any noise, and Marinette held her breath. Seeing the beginnings of a humanoid shape, Marinette pulled the door open all the way, reached her arm out, grabbed hold of the shadowed being, pulled it close to her, and held her knife to the humans throat.
The human protested at this new development, "Come on, can't I ever get close enough to draw a sharpie mustache on you." Marinette sighed and withdrew her knife from Alya's throat. Somehow Alya wasn't fazed by anything. Not even being held at knife-point.
Marinette grumbled at Alya, "What if I had been a Akuma?"
Alya shrugged and smirked, "But you're not. Also I trust you to keep us safe."
Marinette couldn't help feel a small surge of pride, but shook it off and sighed, "Get to the table."
Alya sighed, "You don't have to be so negative." When Alya saw Marinettes expression, she quickly realized that pursuing the matter would get her no farther. Alya grumbled and walked into the kitchen.
Marinette groaned quietly and rubbed her forehead, "Why couldn't Alya understand that they were both orphans. They were living in the fourth wall, were only the poorest people lived. No one cared about them, and Alya acted like they were teenaged girls before the Akuma protection act." Marinette shook her head to clear her head and dispel all of her secret worries, then she sighed and walked into the kitchen to prepare breakfast.
