The Demon Exorcists and the Noah
They found a girl with great strength that wasn't Noah, she had no stigma, wasn't Akuma, and only half human from DNA tests. They experimented on this poor girl child for many years and kept her locked away. She was found at the age of four and was kept locked up for her whole life after being taken by them. Soon when she was six they took her to Hevalska the guardian of the cube and keeper of Innocence. By then she was nothing more than a shell. The attributes she had that made her not human were sealed away with a spell along with her memories u till that point.
She had long crimson red hair the color could be attributes to fresh blood and eyes so blue they make the Ocean seem pale in comparison. She was small for her age and wore only a large white dress shirt covering her pale form that made her seem even smaller.
Koumi and Leverier were there as well. Koumi was disheartened about what was happening to the girl that was the same age as his sister. He asked about her background and was simply told that she was an orphan with great potential that the Vatican was taking care of. 'In other words she has a top class secret background and they would get in trouble if the rest of the organization found out about it' thought Koumi wirily. It wasn't the first time the Black order destroyed loves for the sake of the Holy War against the Earl.
They watched at Heveleska picked her up underneath her armpits as she swayed like a rag doll in her ... arms? Heveleska glowed for a few moments before a innocence rose up from within her that responded to her. Heveleska was surprised that, THAT particular innocence chose the child as its wielder since it has never EVER been able to be used before and it always felt different from the rest of the Innocence...not like it was the Heart but more like it was a black sheep in a family of white ones.
They watched as the innocence went to her and then went inside of her surprising many since it was supposed to be an equipment type from their scans. Leverier was demanding to know what was going on to Heveleska when she replied it was bonding with her soul after a few moments as the girl was engulfed in a glow of green energy. She started counting for synchrorate and surprised many when she got up to 90%.
The girl suddenly shook and her gaze went to the surrounding shadows and everyone jumped when they saw their shadows start to move. Clearly freaking out the shadows extended towards the girl as Heveleska quickly put her down and darkness was on the platform underneath her feat like rising clouds or wisps surrounded her and she seemed possessed and reached into the darkness surprising many and pulled out an intimidating scythe (link on profile).
"Shadows will shift over the moon,
A being who wields the blade of the moon,
She shall control darkness itself,
Girl from both Light and Darkness..."
Heveleska said as the girl collapsed and the blade disappeared and the shadows receeded. Koumi and the others on the platform knew that Heveleska sometimes gave prophesys but to others it sounded more like a legend. Who is this girl they all thought but Leverier was thinking of the correct decision they made about her and the powerful excorsist they now have on their side.
This girls name became known as Shiki nothing more and nothing else. It was a name that came from her mouth and seemed surprise to even say it. An embedded memory perhaps but they kept it and soon became an apprentice to a general many feared for his blood lust or in his case Akuma lust for destroying.
She was never given any help and learned to follow her instincts and master her blade and manipulate her shadows listening to them as they whispered their secrets to her and being able to do things that many thought made her seem like the reaper himself has come since then she became known as Shiki the Shinigami to Akuma who whispered her name in fear and respect.
