Name: Sarah Tustin
Appearance: Sarah is 5"6', with shoulder-length black hair, brown eyes, and somewhat pale skin. She looks slightly Asian, although it's only in the face. She's somewhat overweight, something she is aware of. Her general wardrobe consists loose t-shirts, sometimes with pictures or phrases on them, and blue jeans, along with a black windbreaker with a blue interior. In colder weather she'll wear a thicker red and white jacket. Both of these have large pockets, and she'll keep all sorts of things in them such as paper scraps, mechanical pencils, and loose change. She also wears a pair of brown hiking shoes, which have probably never been used for actual hiking.
Personality: Many seem to find Sarah far more mature than her age would show, and yet at the same time seems to be rather childish. Despite her age, she doesn't seem to be quite ready for the adult world, and still enjoys things that would normally be enjoyed by children. She also tends to be quiet around people she doesn't know or doesn't want to talk to, but will talk openly with friends and people who she thinks are friendly.
Having siblings much younger than her has made her quite tolerant, and she rarely ever seems to get angry. She also dislikes conflict, and usually will try to resolve it when it involves friends of her. However, while she rarely gets angry, she does get annoyed or exasperated, and will often simply get up and walk away if she doesn't want to deal with situations. She's also prone to panicking when things start to go wrong, and often needs to be calmed down by others or her Navi so she can think rationally again.
Sarah's a computer geek and is fairly good with technology. She could almost be considered 'gifted', but she lacks the drive to make particularly complex things, and most of the time she just fixes and upgrades existing tools.
PET Modifications: Her PET has a dark green body with basic black trim. It has the ability to store a gigabyte of data. It can also show a first-person view of what Basilisk sees through her visor.
