Summery: Y/n Scarlatina was your typical friendly faunus that acted more of a big sister to most of the Union Academy students and staff. After being born she was just an ordinary faunus with no Quirk, Semblance or Powers to speak of. However what she lacked in powers she made up for it in her IQ. Fallowing her Grandfather Jack's footsteps. At the young age 5 she had already started building her own inventions despite looking so young. Jack even noticed that she had potential and started teaching her in the ways of making inventions, mixing chemicals, and so on. He even bought her books that seemed to advance for her age, but she still understood them with great ease. 

After her younger sister, Velvet was born the two grow even closer. Even after Velvet had enrolled in to U.A. she started introducing her older sister to her friends. She even meet Demon's thanks to Sirzechs Lucifer, who is one of the founding headmasters of U.A. Going even out of his way to introduce her to the other two headmaster's of U.A. Ozpin and Nezu. The three of them wanted her to join them at U.A, but she respectfully decline their offer, do to the fact that she was already working with her Grandfather making inventions to help people across the world.

During an expedition to the Emerald Forest, with her Grandfather. Y/n being left to explore the forest she came across a strange dark purple crystal, that was roughly around 10 inches. After sharing her findings with her Grandfather, the two sat out to make experiments with it. After having the higher-ups approve of the experiments they started doing the first test run.

During the test run everything way normal, and all seem good. But just as everything was about to finish an earthquake shock the lad, and made the experiment unstable. As the experiment started to lose control, it caused a large explosion that took not only the lab, Jack, and Y/n, but it also took several innocent bystanders.

Despite the fact that the crystal was lost, all of the staff that worked in the lab had lost their lives in the ensuing explosion. It was only after waking up in the hospital that it was revealed that one person had Survived, Y/n. Jack had shielded her from the blast at the last possible moment, but at the cost of his life.

Despite having had lost the people that worked with her, she still tried her best to live up to Jack's dream of trying to help the people around her. After finally being released from the hospital several of her friends and family came to try and help her move on from her grief. And so she did.
