Cold and sharp. Sabrina always tries to supress all type of emotions, specially when she is working. She shut herself when she was a child due of shock, but also was taught to always be calm to supress her demon nature. Still, her nature made her overall work easier since she doesn't take sides because of emotions and is always calm enough to think in the logic path even in difficult situations.

Even so, she isn't heartless. She doesn't show affection as others do, thinking that worrying about a person's life and telling the blunt truth is the most important thing to do for those she appreciates. She cares about those close to her, and will always tries to be there if she is needed.
Still, she dislikes people who always gets carried away by their feelings, seeing it as a huge weakness in success. She is someone who will actually step in from of them an tell them the truth of the situation around them, not only because it gets annoying to her, but also because she thinks is the only way to make everything going smoothly. Sabrina is not scared of being ruthless or inconsiderate if it means it can be of any help for the rest.

Even so, Sabrina is actually a kind person, specially on free time. Losing her family at young age and being mostly alone, made her appreciate those who always stayed by her side. Observing other made her really attentive and even if it takes a bit, she is able to empathize with others. She isn't used to socialize, having spent most of her life alone or interacting with others mostly because of work, Sabrina normally doesn't have any conversation topic unless is pure academic.

Sabrina has an obssesion with organization. Finding just a single thing dirty or out of place will make her re-arrange everything needed. Always keep a schedule and organizes everything by date or name, making everything easier when it comes to find things. She even has an eating schedule, not only extrictly follow it, but also cancelling or denying any other activity during that time.

Sabrina has been in touch with demons since she can remember. Her own mother was a Nephilim like herself, and also a skilled Tamer Exorcist. Having no one else but her mother, Sabrina grew up in the company of various demons, her mother's familiars, who where like her babysitters most of the time, and when she was a bit older, Sabrina's mother started taking her daughter with her to the Order Quarters and even on missions. Sabrina's mother was usually accused of being careless and irresponsable with Sabrina, but in fact she always protected her daughter, and was very proud of how the little Sabrina learned a few things of exorcism just by looking. No much later, little Sabrina was taught exorcism by her own mother.

Despite seeing how the little girl enjoyed the lessons, the main reason for it was to train Sabrina in control her own powers. Nephilim abilities sometimes could be a danger in the eyes of the True Cross Order, and had to know how to keep them under control.

It was during the Blue Night the first time Sabrina lost control of herself.
Like other exorcists in the place, Sabrina's mother was a victim of Satan trying to take over her body. She saw her own mother burning in flue flames just in front of her, trying to keep up as much as possible to survive, but finally most of her body turned into ashes.
In the middle of the panic, Sabrina lost her mind, and the demon, uncontrolled side of herself to get out and start attacking indiscriminately.

Having already Satan's threat out of hands, the first order was to eliminate Sabrina inmediately, and if it wasn't for Osceola's intervention, who was a close friend of Sabrina's mother, that was able to stop the demon girl and disabling her, puttin her to sleep.

The next time Sabrina woke up, some days have already passed. She wasn't able to remember most of the things that happend, but the image of her burnt mother never left her mind.
Exorcist from the order where around her, placing a provisional seal to keep Sabrina going out of control again. Without being able to think about it, say anything or even process it, Sabrina was strictly tied to exorcism and the order. Only thanks to the word of some high rank members, the confused little girl was able to avoid execution, but had to devote to the Order until the day of her death.

Sabrina's training started not long before she got out of the hospital. Not only had a normal exorcist training, but also had extra lessons on how to control herself in any situation. A lot was demanded from her, and she had to give results very quickly.
Under the direct guidance of Igor Neuhaus, Sabrina learned most of her skills as exorcists, and admired the older man even if he didn't showed any apreciation for her student.

At the age of 16, Sabrina was allowed to graduate after extra examns about her condition and the aprovation of high ranks in the Order. Thanks to her grades and training, was easly ranked as an Upper Class exorcist and inmediately sent in difficult missions.
A few years later, she caught the attention of Lewin Light as "an interesting individual" and requested her as a temporal partner. Sabrina, who used to admire Lewin's achievements, accepted the offer with the intention of learning from her superior, even if his behavior was a dissapointment to her. But thanks to her organization abilities and personality in missions, she kept working mainly as Lewin's assistant to the date.
