Saira grew up as an only child due to her mother having serious complications after her birth. Saira being the only biological child her parents were going to have put a lot of pressure on her. Her parents built themselves from nothing, they credit their success to their hard work and dedication to academics. They did not want their only daughter to live the lives they had once led prior to their success. For this reason, they planned to put her through the most rigirous academics they could muster to give her an even greater oppertunity than they had. They raised her like any other child up until she had to end up going to school, they decided it was best if she went to an elite boarding school where she could get the finest education. This boarding school was in another country and away from anything she was ever familiar with. But she respected and cared for her parents a lot and went to the schools she was assigned without any rebellion.

Saira was fairly sheltered growing up, and did not socialize with many children her age before school. When the time finally came for her to attend school, she had a hard time making friends or keeping up in conversations so she usually ended up on her own. Despite her lack of social life, she took it in stride and put a lot of work into her studies. She was diligent and out-preformed many of her peers at a young age. Her parents praised her for this and were very proud of her.

Throughout her academic career in K-12, she ended up being isolated from her classmates more and more. Growing up as the foreign exchange student that never talked to anyone else shaped a reputation that stuck with her even as she became more outgoing. The few mutuals she did make never truly became more than that. These years were particularly lonely for her, as she barely returned home and only kept in touch with her family though letters. Their praises about her grades is what kept her afloat. That was until she started to not preform as well as she used to. She was still an explementary student, but she wasn't excelling in comparison to her peers as she did when she was younger. Her confidence started to dwindle as she began seeing herself as a failure with no other means of support.

Even so, she pushed herself to graduation and was finally able to return home. Finally being back did not give her as much relief as she expected it to. Her parents felt like strangers and the burden of even higher education was the only thing on her parent's mind. She had gone through so much work and turmoil just to be faced with having to leave again and work harder in something she felt like she was failing at. Saira felt like there was no escape and decided to take a very calculated risk. She told her parents that she was accepted and going to a prestigious college, a notion that did not surprise the parents, but it was all a lie. Having never been a trouble child, her parents took her word without asking for any proof. In reality, when she left home she was going on a personal journey to explore herself. Being an adult, she knew that even if her parents found out, there was no way they could legally stop her. Though, she still did not want to disappoint them and risk their resentment and decided to lie as they were the most valued people in her life.

While on her travels, she took various odd jobs to stay afloat to try and find something she was passionate in but nothing ever seemed right. One day, she ran into [Hashira Leader] accidentally, she had no idea who they were or anything about demon slayers but when [Hashira Leader] offered a stable job position for her she could not refuse. They wanted her to do research on wisteria to find ways to utilize the flower against the demons. [Hashira Leader] needed someone who specialized in biology in order to even begin this project and saw the perfect spark in her.

Saira stayed in a simple research position for a few months living on the land where the Hashira trained. She would get to know the Hashira little by little and showed a bit of interest in the training. She began to join training sessions on her free time and found herself to be fairly affluent with a weapon. She had never previously tried many physical sports/activities before and did not realize how much she enjoyed them. She trained for about a year until she was ready to begin killing demons and climbing the ranks. Wanting to prove her usefulness beyond her intelligence, and striving for a purpose, she rose to the top very quickly. At the same time, she continued the job assigned to her by [Hashira Leader] and had created a breathing style that acclimated to her better using her research.
