Oboro's family once owned a well-known kimono shop that bore strong connections to the royal family of Hoshido. These connections proved to be fatal to her parents, as the political and economic influence that they gained caused them to attract the attention of Nohr, resulting in them being ambushed and killed by a Nohrian assassin when they were en route to Nohr on a business trip. Oboro survived by hiding in a cart, and she was thereafter taken in by relatives who worked directly for the Hoshidan nobility. Through this connection, Oboro eventually learned how to wield the Naginata, thereafter enlisting as a soldier in the Hoshidan army. Some time after her enlistment, Oboro was appointed as one of Prince Takumi's personal retainers. She is the quickest in changing clothes. Her birthday is November 28th.
