Gabrelle tries very hard to be like the gangsters in her favorite movies and she idolizes Giganna, whom she sees as the empitome of punk cool. Gabrelle also looks up to Crystal and Kumi, and even acts as their toady for all sorts of mean pranks. Min-chan is often the target of Gabrelle's cruelty. She loves to boss around anyone weaker than herself and has a flagrant disregard for authority, but she doesn't have the strength to back up her bravado. Basically, her bark is worse than her bite.

Around school, Gabrelle is constantly skipping out and she's been held back a couple times. She doesn't really have any close friends, which may be why she is so disagreeable. But underneath it all, Gabrelle really just wants to fit in.

She actually has a secret passion for fashion and any number of magazines can be found hidden in her dorm room, though some of them are of an adult nature.
