Chloe was born to an Australian father and a Japanese mother in Narragyambie, making her a natural of the small town Tallygarunga's located in. The two decided to move there before her birth due to cheaper land, as they wanted to migrate their businesses: her father owned a small time bakery, and her mother wanted to open a multiple martial arts dojo, wanting something closer to home and wanting to retire from her competitive career so to take care of Chloe. The fact that there was so much youth around their general area because of the Academy made it so their businesses minimally flourished and they never faced much of a financial burden ever since.
Chloe was soon followed by a younger sister, with barely a year's difference in between them. The two were inseparable from then on, even if Chloe took over the role of overprotective big sister more than anything else. Despite her solitary ways growing up, she always made time to either tutor her sister in school (whether it be muggle or wizard) or to spend some quality time with her, regardless of how busy she made herself at any given time.
She proved to have quite a bit of energy to waste as a small child, which led her mother to enroll her in the few combat sports and martial arts her dojo actually taught. Chloe seemed to pick up on all of them instinctively; the apple did not fall far from the tree. However, unlike her mother, she didn't seem to present a competitive edge at all. Rather, she liked to exploit, study and perfect the art and never really bothered with wins and defeats. Frustrations aside, her mother concluded it wasn't meant to be. Chloe agreed to continue practicing regardless, actually liking to have a sound body.
Her magic developed not too long after, and so did her sister's. Their parents opted to let them conclude elementary school first despite repeated pushes from the school to let Chloe skip grades. They didn't listen as they saw their child developing what seemed to be severe social issues, and didn't want to separate her from her peers and make things worse. As such, she only reached Tallygarunga to take on the first year, skipping everything that came before completely.
Growing up she demonstrated an aptitude for logic and mathematics, and eventually technology, having access to plenty of it within her own household - her father was a bit of a geek himself, and allowed her free reign over his devices so long as she was supervised. When she eventually proved to be competent enough to handle things, he got her a computer and she requested programming books. This only increased her parents' worry, as she'd spend days upon days closed off in her room during break periods just to tinker with the machine.
The next step to help their daughter was to send her to the dormitories during the third year, even though they lived within walking distance of the school (or walking distance for Chloe anyway, as she rather enjoys to walk). She was given a magic-proofed smartphone so to keep in touch with them, but outside of that she wasn't given any sort of technology whatsoever to keep. This frustrated her greatly as she was only allowed home during days with no classes, and so she took on a second hobby - model making. She would sneak her figure to school during week days to assemble, and once that was achieved she'd bring it back home to paint and finish. The idea backfired and Chloe isolated herself further.
As the years went on the parents seemingly got desperate as they didn't know what to do for their daughter anymore; but Chloe is far more concerned with other things. What does she actually want to do? Programming? Teaching? Join the MRI? Or dive into her newly developed passion for magizoology? She could only hope the last two years in Tallygarunga would send her some sort of sign towards what she should do before it was too late.
Through the influence of Alexander Winfield, Chloe made the decision to join the local Nature Reserve as a trainee; luck wouldn't remain on her side, however, as the work load she was subjected to increased from all sides as the year rolled over to 2019. A combination of pressure from the incoming SPIDER exams, the work at the Reserve, and the newly acquired responsibility of instructing Muay Thai to newcomers of the dojo, along with more students to tutor on top of that, made it so the Sturt is constantly exhausted and prone to falling asleep in class.
At the end of May, her grandparents came to visit from Japan. The strict duo has made her and Lexi's life unbearable for the extended duration of their stay, and, for the moment, they seek out every potential excuse they can get to avoid their household: in Chloe's case, even socialization. She started paying much more attention to QuillBook, increasing her activity on the platform deliberately, and started hanging out with her friend, Tyson McKennis, more than she normally would - the fact their stay coincided with his break from college greatly benefited her.
