Photographic memory, good observational skills, strong enough to lift another person, lightning fast reflexes, and an interesting aptitude for magic . . . .
The strength, observation skills, and reflexes could potentially have been developed as survival mechanisms from whatever hell her "adoptive parents" put her through. Her magic may be some kind of "monkey see, monkey do better" baloney, but I'm going to assume from the pacing and immediate introduction of a rival that that's not the case - she was probably just kinda slapped together to be able to handle just about anything with little to no character development.
Ah, well, it's still interesting :)
