Lien was born in Mistral to her father, Hoàng Khánh Văn Lê (Lê Văn Khánh Hoàng), an archaeologist, and her mother, Anh Kiều Thị Nguyễn (Nguyễn Thị Kiều Anh), who was a stay at home mom. She had a little sister named Linh Diệu Lê (Lê Diệu Linh) who she shared a close bond with. Her parents were caring and they had a nice home, a nice life. On one trip Hoàng took to take a look at some old relics in Vacuo, he brought his family along for Anh’s birthday celebration. Grimm attacked the family and the bodyguards left Linh behind because she was hidden by sand. Lien’s parents died of bloodloss at the hospital. She then was moved back to Mistral for the funeral and placement at an orphanage. She spent her time miserably there until her new parents adopted her, Akio and Nanami Shirogane.
The Shiroganes worked as (high-ranking) servants for Ning and Wei Yao, a powerful and wealthy Mistrali family to ‘repent’ for a crime they’d committed in the past. At first it was okay, the Yaos and Shiroganes being on good terms, but as the White Fang became more violent, the Yaos became scared because they took advantage of Faunus labor. Ning and Wei started to become crueler and more racist to Faunus in private, Lien included, who was now forced to work with her parents when not at school. They also grew paranoid that others would betray them, so they held Nanami and Akio’s crime over their heads to keep them loyal. When Lien was 10, Ning and Wei’s daughter, Yu, died, and the Weis become even more paranoid and embittered,hiring more security of the robotic kind to guard the manor and other establishments. Akio was made to do Wei’s dirty work, increasing the blackmail he had on the Shiroganes. Lien was treated even worse, and her parents even pulled her out of school, simply hiring tutors and combat trainers to keep her safe. She’d always wanted to be a huntress, so she relished the opportunity, even with her surroundings. When Lien was 15, the Yaos were setting up a plan to draw the White Fang out, sending some of their armed personnel onto a cruise ship they said they’d be going on while really staying at the manor. The White Fang caught wind of this and they sent a smaller group to sink the ship and a larger one to raid the manor, disguising it as a trip to steal to divert blame on the death of Wei and Ning. The White Fang succeeded, killing the Yaos. The Shiroganes escaped unscathed and ran to Vale, where they started anew and enrolled Lien in Beacon when it was time.
