Nyss

Synn's sister, created by the Alchemist Dahlia.
When both sisters woke up from the animation the distinctive features where put on each of them by the blood of Dahlia, while Synn got black hair and the tattoo that Mia brandishes, Nyss took the red of that mark on her hair. But there was more than just the physical traits that made the sisters different, while Synn was polite and educated, Nyss was incapable to even speak, almost as a child and as a child she stood close to her mother at all times.
As time went by, some traits where found on the two girls, Nyss fought as graceful as Mia and using the same weapon while strangely Synn started to use the Chinese sword, oddly enough it seemed like the own shards of the soul blades had memories of their own too at least for combat purposes, still Nyss wouldn't develop any other skill, she acted as an infant only being able to say "mama" although it was good enough for Dahlia.
Some time later, Dahlia decided to make a last try with a daughter made of the white ryugami himself and this last was the perfect result of all her efforts.
While Dahlia was creating her new daughter, both sisters felt neglected by her new sibling, on one hand Synn went away and leaved her home while Nyss grew a grudge towards the new girl, so great to even kill her.
Even though Dahlia noticed her daughter to be gone, she decided to stay and put all of her to train Dracia, given to her fresh memory and the fact of her being close to become as her “father”.
Nyss couldn’t stand the situation; her mother was being taken away by that blue eyed girl and blinded by hatred she decided to kill her. Though Dracia wasn’t aware of the blow she reacted just a second in time avoiding the imminent decapitation, Dracia tried to talk some sense on Nyss but nothing would stop her even worse, the only thing she had to defend herself was her wooden sword which was quickly crushed by the merciless ringblade of Nyss, the slashes were quick and deadly, and Dracia was being wounded by the frenzied barrage of the red headed girl. With no other choice, Dracia used her dragon shape to finish this fight and threw a powerful bite at Nyss trapping her hands between her jaws but even then Nyss wouldn’t stop fighting, she pulled away to keep fighting but this was fatal for her given that she would lost her hands on that struggle. Nyss shrieked in pain bleeding all over the field and still punching the dragoness with her stumps crying while she called over and over again for her mother, till Dracia flew away.
Nyss fell to the ground quivering by the hatred she felt toward that white dragon. Synn felt the pain on her sister and made her head back to look for her, when she found her laid down on a puddle of blood, barely whispering “mama” she took her and headed back home.

With Dracia gone, there was no more distraction for the love of her mother but the hatred Nyss felt was too powerful to let the white dragon just go, she needed to pay for all she did.
Dahlia felt the guilt of letting this happen to her daughter, it was horrible to see her beautiful creation suffering because of her, so she decided to make amends for her child.
Given that she didn’t have the hands she needed to make some new ones for her, so she worked night and day to craft a pair of hands. The night she finished the hands she went to Nyss’s room to put them, and when she gently attached the new hands, Dahlia whispered to her daughter “this will be the wish you waited for my child” as this hands attached to the forearms it started to morph into something else, the beautifully crafted pair of hands grew into a pair of dire claws. “Her wish is revenge mother” said calmly Synn while she stood by the door drinking from a glass.
Now Nyss had talons, each claw was a dragon slayer. She remained calmly beside her mother who put a magical choker to calm the enraged spirit of her daughter.
Even though Dahlia calmed her daughter she fears that one day the two daughters meet again and not even all the magic in the world can avoid the rage to burst thru Nyss
